When I try to play Amazon Prime videos on my Fedora laptop, they never start. Instead, the screen gets stuck on a loading animation (spinning circle) indefinitely. How can I fix this? Is there a step-by-step guide or checklist I can follow? [Edit July 31] This appears to be hardware dependent. It works okay on my desktop (Intel i7-4790 with GeForce GT 730) but fails on my laptop (Intel Celeron N4500 with Jasperlake embedded GPU) despite having followed the checklist on the Fedora website. Just today, I found the

utility. On both systems, it says in the properties section:

What command would I use to convert an mp4 or mv4 video file to an animated gif, and vice versa. That is, convert a animated gif to a mp4 or mv4.

I used intel xorg driver (xserver-xorg-video-intel) plus i965-va-driver on Debian Bookworm; everything worked fine, 2D, 3D, video acceleration. After updating to Trixie, intel xorg driver (same setup as bookworm) doesn't provide acceleration. glxinfo shows LLVMpipe instead of Mesa Intel(R) HD Graphics 630 (KBL GT2) (that's the graphic device on my laptop). I switched to modesetting as suggested for years on Debian; 2D, 3D acceleration works fine on modesetting, but as expected, I have screen tearing on videos. I'd prefer to avoid xorg compositors. Wayland is not an option for me due to certain apps I use and still don't work well on it. Any ideas how to have acceleration using intel driver on Trixie, as in Bookworm?

all. Hope you guys are doing well. I have downloaded a 28min mp4 from a site but its audio and video got downloaded into 2 separate mp4 file both of 28min. Now how can I merge them? Thanks in advance Attaching ffprobe info for those file below

My notebook, an older Apple MacBookAir 13" with Intel Core i7 an Intel HD Graphics 5000, used to work fine before the upgrade to Trixie (Debian GNU/Linux 13). Now, after the upgrade, all rendering is done using the CPU instead of the GPU. This is annoying and makes the machine feel slow. I would like to have accelerated hardware rendering back, but I don't know where to start troubleshooting this. All relevant packages seems to be installed. The GPU is detected. But llvmpipe is used for all rendering instead. System info:

There is no /etc/X11/xorg.conf on my system. /etc/X11/xorg.conf.d/ contains a file called 20-displaylink.conf:

Section "Device"
    Identifier  "Intel"
    Driver      "intel"
EndSection

Plus, another file called 90-xpra-virtual.conf which was automatically created:

# Ignore all xpra virtual devices by default,
# these will be enabled explicitly when needed.
Section "InputClass"
        Identifier "xpra-virtual-device"
        MatchProduct "Xpra"
        Option "Ignore" "true"

A *systematic troubleshooting guide* would be most helpful/appreciated. Unfortunately, I could not find a suiable one online = one that is specific to this piece of hardware and one that does include a fix, not only diagnosis. P.S.: I have another older computer (an older MacMini) that also has an Intel chipset/GPU, also uses the i915 driver and suffers from the same type of problem (renderer: llvmpipe instead of GPU, even though GPU seems to be "recognzied"). So I am pretty sure that this is related to the upgrade to Trixie/Debian testing. Other than that, I have no idea as where to start troubleshooting this.

Anyone knows how can I check/test my 2d acceleration? See if it's on/off and working correctly and as efficient as it should? I have SIS 771/671 on Zorin OS 8 Lite. I believe the resolution should be better (it's 1024x768 right now and it looks a bit stretched horizontaly I assume 1024x1800 could look fine) and I feel video could go more smoothly and also I see some horizontal lines on the screen when playing movies. So basically I think that the video driver is still not proper here. I found this instruction here at comment #230: sis drivers discussion I have a patch here : https://www.archlinux.org/packages/?name=xf86-video-sisimedia btw the patch is for 13.04 - will it also work or be needed for 13.10? Otherwise is there any other recommended lite distro on which SIS 771/671 could work fine and with acceleration ON?

I am trying to get my Blackmagic Quad HDMI Recorder working on Arch Linux. Since rebooting after the first installation, the device was never recognized by Blackmagic Software on Arch, while it continues to work on Windows. I suspect that this has to do with [the latest version of Desktop Video not released for Windows.](https://www.blackmagicdesign.com/support/family/capture-and-playback) A Fedora user created module patches for the [blackmagic](https://forum.blackmagicdesign.com/viewtopic.php?f=12&t=223633) and [blackmagic-io modules](https://forum.blackmagicdesign.com/viewtopic.php?f=12&t=215626) , but they failed on my PC.

How can I use [ffmpeg](https://ffmpeg.org/) to reduce the size of a video by lowering the quality (as minimally as possible, naturally, because I need it to run on a mobile device that doesn't have much available space)? I forgot to mention that when the video can use subtitles (*.srt or *.sub), I'd like to convert them too to fit the parameters of the converted video file.

I want to completely disable the output of any messages on the screen when the system boots. nomodeset, quiet - don't work properly for me. Error messages still appear. Ideally, I want to see a message on the monitor - "no signal". The best I've been able to achieve is setting console=ttyS0, but I'm not going to use the serial port. I tried to disable the framebuffer but that doesn't work either.

I have the following setup:\ i.MX8MM + uDP72020 (PCIe to USB-3.0) + UVC-Camera\ Linux: 6.6.69\ GStreamer: 1.24.0 (imx) GStreamer pipeline I am using:

gst-launch-1.0 -e -vvv v4l2src device=/dev/video0 \
               ! video/x-raw,width=1920,height=1080,format=YUY2,framerate=30/1 \
               ! imxvideoconvert_g2d ! kmssink connector-id=35 can-scale=false sync=false

Unfortunately this doesn't work, as I get around 1 fps. Lower resolutions like 1280x720 work fine. So I thought maybe it is a performance issue on the host side, but the i.MX8MM should be able to handle this resolution. While debugging the issue and looking into stuff, I started usbmon to maybe see errors or something. But as soon as I started usbmon, everything worked fine, even at 1920x1080@30fps. So the above GStreamer pipeline only works when usbmon is running at the same time! So my question now is, why? Why is the USB communication suddenly so much better when usbmon is running and logging all the traffic? Is there anything usbmon does, which I could potentially also do to improve my setup? Thank you and best regards, Stefan

This is a really specific question, I have come here before because of it but now I really think I am out of options and trying to see if anyone has experience with this specific video card. Have tried to install the drivers for it 4 times in the past and nothing has worked. First time with the .run available in their webpage, nothing happened because an error appeared. Then tried using nvidia-detect but it didn't detect anything. So I added the non-free path to download nvidia-driver, nvidia-smi and nvidia-xconfig packages. The first time I ran them only having installed bumblebee but not bumblebee-nvidia so system wasn't bootable after restarting, had to purge everything of nvidia's and restore /etc/X11/xorg.conf to blank (original state), filed a bug report as someone in here recommended and they told me I needed bumblebee-nvidia for it to work. Downloaded bumblebee-nvidia, downloaded all those packages again and the system wouldn't boot after restarting, again. Then tried again with the package from NVIDIA's webpage, this time without a graphics interface since it required that, and system crashed again. **For all those 3 times that the system crashed I had to purge everything nvidia related and restore to blank the xorg.conf file and then type startx to have graphical interface again. Next I tried what Debian's official page says , basically get things from backports, followed the steps to the line and it wouldn't boot again after restarting, purged everything I installed and everything nvidia related and it wouldn't boot having used the same fix I had done the previous times. A kind heart told me I had to reinstall nouveau for it work again, and it did after doing that. Can you please help me on how I could install this specific video card's driver? I have tried everything I have found online and I don't know enough to make up solutions as I go. I can't change the brightness of the screen, can't connect extra monitors, can't use redshift (my eyes are sensitive) and can't even invert colors because of the lack of the driver. Previously asked question here on the site Bug Report with more information Using Debian 8 with Gnome 3, my computer has two video cards an intel (integrated) and the NVIDIA card. Please tell me if more information is required. --------------- Edit: to put the results of the comment $ sudo apt-get install bbswitch-dkms intel-microcode firmware-linux-nonfree bumblebee bumblebee-nvidia primus primus-libs primus-libs:i386 linux-headers-$(uname -r) nvidia-driver Reading package lists...

I am having a problem with VLC when I play HQ videos (720p and higher): when I try to look for a particular scene (say I am playing a movie and want to get to go to 30 minute mark) the sound goes off. It doesn't happen always but it does happen frequently, and when I loose the sound is only on the video I am playing. I never have this problem on Parole Media Player, so I think something must be misconfiguled on VLC. Does anybody have any idea what could be wrong and how can I fix it? ----------------------------------------------------- **Update:** Following the advice from Skuminder, I ran vlc -vvv my_video.mp4

I noticed that VLC could not display the sound of videos that used AOMedia's AV1 codec, or AOM-AV1 in short. When I tried to play videos in that specific codec, I could only hear the sound of the video. This did not occur in other codecs such as H.264 and H.265. I ran video players in terminal, hoping to catch error messages.

This EDID is from a Lenovo P32p-20 4k monitor connected to a ThinkPad P16v Gen 2 laptop (Intel 155H). On other laptops (older thinkpads and macbooks) it works at 4k@60hz but on newer Intel ThinkPads including P16vG2 & X1 Carbon Gen 12 it only works at 4k@30hz. On Windows 11 I can select 59.95hz but then the resolution drops to 2560x1440. Going back to 4k reverts to 30hz. I originally suspected a flakey EDID or Linux decoding it but now I suspect the Intel/ThinkPad hardware. I note it says "EDID conformity: FAIL". The laptop's built-in panel (eDP-1) correctly shows "3840x2400 59.98*" but the external Lenovo monitor (DP-4) only goes to 30hz according to xrandr. OS is OpenSUSE w/KDE + Wayland however I think the desktop environment is unrelated because it's a kernel issue decoding the available modes, right? edid-decode (hex): 00 ff ff ff ff ff ff 00 30 ae a2 62 00 00 00 00 1c 1e 01 04 b5 46 27 78 3a e5 a5 ae 4f 43 ab 26 0c 50 54 a1 08 00 d1 00 d1 c0 b3 00 81 c0 81 80 95 00 a9 c0 81 00 4d d0 00 a0 f0 70 3e 80 30 20 35 00 b9 88 21 00 00 1a 00 00 00 fd 00 17 4c 1e a0 3c 01 0a 20 20 20 20 20 20 00 00 00 fc 00 4c 45 4e 20 50 33 32 70 2d 32 30 0a 20 00 00 00 ff 00 56 4e 41 34 59 35 33 52 0a 20 20 20 20 01 b7 02 03 1b f1 4e 61 60 5f 10 1f 05 14 04 13 12 11 03 02 01 23 09 7f 07 83 01 00 00 a3 66 00 a0 f0 70 1f 80 30 20 35 00 b9 88 21 00 00 1a 56 5e 00 a0 a0 a0 29 50 30 20 35 00 b9 88 21 00 00 1a 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0c ---------------- Block 0, Base EDID: EDID Structure Version & Revision: 1.4 Vendor & Product Identification: Manufacturer: LEN Model: 25250 Made in: week 28 of 2020 Basic Display Parameters & Features: Digital display Bits per primary color channel: 10 DisplayPort interface Maximum image size: 70 cm x 39 cm Gamma: 2.20 DPMS levels: Off Supported color formats: RGB 4:4:4, YCrCb 4:4:4, YCrCb 4:2:2 First detailed timing includes the native pixel format and preferred refresh rate Color Characteristics: Red : 0.6826, 0.3105 Green: 0.2626, 0.6689 Blue : 0.1503, 0.0488 White: 0.3134, 0.3291 Established Timings I & II: IBM : 720x400 70.081663 Hz 9:5 31.467 kHz 28.320000 MHz DMT 0x04: 640x480 59.940476 Hz 4:3 31.469 kHz 25.175000 MHz DMT 0x09: 800x600 60.316541 Hz 4:3 37.879 kHz 40.000000 MHz DMT 0x10: 1024x768 60.003840 Hz 4:3 48.363 kHz 65.000000 MHz Standard Timings: DMT 0x45: 1920x1200 59.884600 Hz 16:10 74.556 kHz 193.250000 MHz DMT 0x52: 1920x1080 60.000000 Hz 16:9 67.500 kHz 148.500000 MHz DMT 0x3a: 1680x1050 59.954250 Hz 16:10 65.290 kHz 146.250000 MHz DMT 0x55: 1280x720 60.000000 Hz 16:9 45.000 kHz 74.250000 MHz DMT 0x23: 1280x1024 60.019740 Hz 5:4 63.981 kHz 108.000000 MHz DMT 0x2f: 1440x900 59.887445 Hz 16:10 55.935 kHz 106.500000 MHz DMT 0x53: 1600x900 60.000000 Hz 16:9 60.000 kHz 108.000000 MHz (RB) DMT 0x1c: 1280x800 59.810326 Hz 16:10 49.702 kHz 83.500000 MHz Detailed Timing Descriptors: DTD 1: 3840x2160 59.996625 Hz 16:9 133.312 kHz 533.250000 MHz (697 mm x 392 mm) Hfront 48 Hsync 32 Hback 80 Hpol P Vfront 3 Vsync 5 Vback 54 Vpol N Display Range Limits: Monitor ranges (Bare Limits): 23-76 Hz V, 30-160 kHz H, max dotclock 600 MHz Display Product Name: 'LEN P32p-20' Display Product Serial Number: 'VNA4Y53R' Extension blocks: 1 Checksum: 0xb7 ---------------- Block 1, CTA-861 Extension Block: Revision: 3 Underscans IT Video Formats by default Basic audio support Supports YCbCr 4:4:4 Supports YCbCr 4:2:2 Native detailed modes: 1 Video Data Block: VIC 97: 3840x2160 60.000000 Hz 16:9 135.000 kHz 594.000000 MHz VIC 96: 3840x2160 50.000000 Hz 16:9 112.500 kHz 594.000000 MHz VIC 95: 3840x2160 30.000000 Hz 16:9 67.500 kHz 297.000000 MHz VIC 16: 1920x1080 60.000000 Hz 16:9 67.500 kHz 148.500000 MHz VIC 31: 1920x1080 50.000000 Hz 16:9 56.250 kHz 148.500000 MHz VIC 5: 1920x1080i 60.000000 Hz 16:9 33.750 kHz 74.250000 MHz VIC 20: 1920x1080i 50.000000 Hz 16:9 28.125 kHz 74.250000 MHz VIC 4: 1280x720 60.000000 Hz 16:9 45.000 kHz 74.250000 MHz VIC 19: 1280x720 50.000000 Hz 16:9 37.500 kHz 74.250000 MHz VIC 18: 720x576 50.000000 Hz 16:9 31.250 kHz 27.000000 MHz VIC 17: 720x576 50.000000 Hz 4:3 31.250 kHz 27.000000 MHz VIC 3: 720x480 59.940060 Hz 16:9 31.469 kHz 27.000000 MHz VIC 2: 720x480 59.940060 Hz 4:3 31.469 kHz 27.000000 MHz VIC 1: 640x480 59.940476 Hz 4:3 31.469 kHz 25.175000 MHz Audio Data Block: Linear PCM: Max channels: 2 Supported sample rates (kHz): 192 176.4 96 88.2 48 44.1 32 Supported sample sizes (bits): 24 20 16 Speaker Allocation Data Block: FL/FR -

Well, my problem is very complicated, I've an old machine (Dell Vostro 1000) where I'm using Debian 8 with XFCE. This machine have an integrated video card (ATI MOBILITY RADEON XPRESS 200 - Model: 1150), and it doesn't work with Debian default configuration. Let's see what I already have tried: - To turn on my laptop without it shows the notorious colored stripes I need use the "nomodeset" code on grub.cfg. - The Debian 8 appears don't have the xorg.conf (???), I made a Xorg.conf following the instructions at https://wiki.debian.org/AtiHowTo , without success. - I tried already tried follow the procedures in the page above, cause the current proprietary driver is not compatible with my old video card. and the older version (legacy) can't be installed and shows some conflicts with "X". This way I have to use the generic linux driver. - I tried set the display resolution using XRANDR, but it fails and when I made the insertion of another resolution, I just can't select this. - Thinking about modules, maybe I can see a little ligth in the end of tunnel. I find a blacklist file into "/etc/modprobe.d" and removed the module "radeonfb" of blacklist, but when I tried to restart, the machine only shows a black screen with the mouse pointer only. to fix this I changed the "quiet" entry of boot line and changed it with "single" to show the command line and I can see that when the module "radeonfb" is loaded, the letters of command line become small (like it have made a resolution adjustment) but I need understand why only a black screen and the mouse pointer is showed. **NOTE:** The xorgs and firmware-linux are installed but doesn't work. I really don't need 3d acceleration, but I need to resize my screen. Actually it's 1024x768 but the hardware can show 1280x800.

I am trying to configure my [Blackmagic DeckLink Quad HDMI Recorder](https://www.blackmagicdesign.com/products/decklink/techspecs/W-DLK-36) to work with OBS on Arch Linux. On Windows, I could go to [their website](https://www.blackmagicdesign.com/support/family/capture-and-playback) , install their Desktop Video 14.5 Program. Once the drivers were installed, OBS would recognize the device. Linux wasn't as straightforward. I downloaded [14.4.1](https://swr.cloud.blackmagicdesign.com/DesktopVideo/v14.4.1/Blackmagic_Desktop_Video_Linux_14.4.1.tar.gz?verify=1748017031-8xieTBOzdt4rQ%2FPasifFSs1vESAzwvSPyHGl7hgaJv0%3D) because they did not provide a Linux version for 14.5. I unzipped the

.tar.tar

which contained

for Debian,

for Fedora, and

for miscellaneous systems. I navigated to

./other/x86_64

and unzipped

-14.4.1a4-x86_64.tar.gz

. I then moved to

./usr/bin

, where I found the executable

. When I ran it I got

Desktop Video Device Detected

. The files in the folder were subsequently found in my actual

/usr

and

/etc

, so the installer likely did its job. However even after a reboot OBS still won't recognize the device. Neither

Capture Device (V4L2)

nor

Capture Device (Pipewire) (BETA)

display my capture device as an option.

I am not sure what I am supposed to do now, as the OS does recognize the device.

I'm using Linux Manjaro 0.8.13 on my laptop and want to install proprietary drivers. Here is what I have: efog# lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Thames [Radeon HD 7500M/7600M Series] (rev ff) At first, I've tried to install drivers using "Manjaro Settings Manager" and "Hardware detection". Right-clicked on "video-catalyst", then "Install", rebooted and got black screen without X. Then I've tried to install it manually. At first I downgraded my xorg-server to version 1.15. Here is all of what I did then: yaourt catalyst-test #conflict with mhwd yaourt catalyst-total-pxp #conflict with mhwd sudo mhwd -i pci video-catalyst #ok, but black screen Then I removed mhwd with -Rdd option and tried to install catalyst again.  I got this: Building fglrx module for 3.18.15-1-MANJARO kernel ...
