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:

SUBSYSTEM drm
DEVTYPE drm-minor

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.

When I tried GNOME Video, also known as totem, it didn't even play the sound.

GUI - An error occurred: Could not initialise OpenGL support The videos play just fine on VLC on Windows so the videos aren't corrupted. What packages need to be fixed here?

I noticed that AlmaLinux 8.10 lacks the packages mozilla-openh264 and it's prerequisite openh264, and that both are absent from official repositories too. To my knowledge, I need these both in order to be able to play H264 videos on Firefox, like on https://udemy.com . I downloaded the packages from these URLs: 1. https://rhel.pkgs.org/8/raven-multimedia-x86_64/openh264-2.4.1-2.el8.x86_64.rpm.html 2. https://rhel.pkgs.org/8/raven-multimedia-x86_64/mozilla-openh264-2.4.1-2.el8.x86_64.rpm.html Then installed them with: sudo rpm -i .rpm I also activated the H264 plugin on about:addons. But still, about:support points H264 as not supported. What am I missing?

I am using Fedora 40 with Gnome. I am somehow able to play mkv video files with vlc after installing its plugins but I want to install codecs in the system so that I could play videos with any player like Gnome videos or Haruna. Tried rpmfusion and many other but idk if I missed something there, nothing worked. Can anyone guide me to get things working?

My girlfriend accidently bought an audio book on the internet and she saved it on my hard disk in windows media audio format (.wma) and now she asks me how to listen to it. I'm a bit puzzled this format still survived. I'm on ArchLinux, kernel 4.2.1-1-ARCH. My first idea was simply trying to read it with VLC as it usually is a general problem solver for audio files and comes with a couple of codecs. But it didn't work. Second idea was converting, I usually use Audacity for quick format swaps, but after several attempts of exporting to ogg/vorbis or ogg/opus I noticed Audacity already failed to read the proprietary file format. I looked up the codecs section on arch wiki but it does not contain any hints for WMA. How to proceed? How to convert audio/x-ms-wma to audio/ogg, audio/vorbis, or audio/opus format?

I recently installed KUbuntu on a Lenovo Ideapad laptop. It's functioning fine aside from a problem that came up with a recent update—after updating all packages, three remained: GStreamer Multimedia Codecs libgstreamer-plugins-bad1.0-0 libgstreamer-plugins-base1.0-0 With the message that: Package failed to install: Error while installing package: trying to overwrite '/usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstcamerabin.so', which is also in package gstreamer1.0-plugins-good This is very strange. The only things I've added on to the system have been Krita, Blender (as a direct download, nothing fidgety), and OpenToonz through Snap. Attempting sudo apt upgrade from the terminal gives me this output: Reading package lists... Done Building dependency tree... Done Reading state information...

I am using openSUSE Leap 42.2 and Opera 46.0.2597.57. Some videos on the internet (maybe the half on YouTube) do not work on Opera. YouTube tells me that I cannot watch the video and suggests me visiting https://www.youtube.com/html5 . *H.264* and *MSE & H.264* are not supported by my browser as the page mentions, although Opera is listed as suported. I did some research and installed the following packages (which were not the sollution): - chromium-ffmpeg-extra - chromium-ffmpeg-extra-debuginfo - chromium-ffmpegsumo Maybe I need to mention that Firefox works pretty fine with YouTube and other videos that do not work on Opera. Thanks a lot for your help. PS: If this issue is fixed with openSUSE Leap 42.3 this would be an option for me, but I still hadn't enough time for an update.

I'm trying to play videos I recorded from my mobile phone (the stock video / photo app on a Samsung Galaxy On7). When I click them I get the following error message from Totem on Fedora 28:  > H.264 (High Profile) decoder is required to play the file, but is not installed Clicking "Find in programs" doesn't find an appropriate codec. --- The file tool labels them as "ISO Media, MP4 v2 [ISO 14496-14]". --- This is the error log when I run Totem from the CLI: > ** Message: 12:57:35.979: Missing plugin: gstreamer|1.0|totem|H.264 (High Profile) decoder|decoder-video/x-h264, level=(string)4, profile=(string)high, interlace-mode=(string)progressive, chroma-format=(string)4:2:0, bit-depth-luma=(uint)8, bit-depth-chroma=(uint)8 (H.264 (High Profile) decoder)

Resolve is a commercial video editor with a free version that can be run on linux. On the linux version, some videos in mp4 format will have no video content when they are imported. This is apparently because the AAC codec is not supported by the free version Resolve on linux. Apparently these videos can be transformed before being imported into Resolve, so that AAC support isn't required. Apparently ffmpeg is the correct tool for this job. If I simply copy ffmpeg commands that I find on the web, I get errors that I do not understand. At present I'm trying this command: > ffmpeg -i video-to-transform.mp4 -c:v prores_ks -profile:v 3 -vendor > apl0 -bits_per_mb 8000 -pix_fmt yuv422p10le > outout.mp4 ...

The command generates many of the same warnings as when reproducing with VLC:

I am a hardware designer who is working on a custom processor circuit board with audio support. Our intention is to have the processor running some flavor of Linux and interface with the audio chip over PDM/I2S. One of my considerations in selecting an audio chip is minimizing headaches for our software team. I would like to pick something that simplifies the driver development process, if possible. In my research, I came across this Texas Instruments Linux driver page that explains that they have a driver "available in the Linux mainline". My gut sense is that having mainline Linux support sounds like an advantage, but I don't understand it enough to explain what the advantage is, or have a sense of how much effort it will save. I also came across linux/sound/soc/codecs in the Linux kernel Github page. Is this the list of audio chips that are "available in the Linux mainline"? Can I pick any of the chips listed here and assume that it will make the software team's life easier? Will they be able to simply enable the driver in the kernel, and the OS will recognize the audio chip automatically? What exactly does it mean to have a driver in the Linux mainline? How do I know what chips have mainline drivers, and how much of an advantage is it to use them?

As can be seen on https://www.kernelconfig.io/search?q=wm8962&kernelversion=4.19.165&arch=arm64 there are seemingly two different kernel modules for the audio codec WM8962 and they have entirely different dependencies as well. Is there a good way to determine which one should be utilized? I understand that one of them is for i.MX boards but what exactly is the difference? Does one need to dive into the code to find out about the variations?

I want to share my script to do this with Media Info CLI and python. At first I tried with pure bash but should have just gone python at first, much quicker and adaptable (for me). My task was to recursively go through all files in a specified folder (in this case on a NAS), and print as well as store in a txt file all the video codec and profile level used in each. The reason be I found some older Samsung TV wont play H264 with profile level greater than 4.1 , so some re-encoding was in order, also the latest Samsung TV have dropped support for xvid/divx.

I used to cut recordings from my satelite receiver (mts files with one video and multiple audio streams) with openshot, but I have a problem since upgrading from good old debian jessie to buster: - Converting the mts video and ac3 stream gives me a video with silent audio stream with only rare random noise - Using the mp2 audio stream of the mts instead works as expected - Playing the mts video in openshot (which seems to use ffmpeg internally) gives wild noise with almost no relation to the correct audio stream - I can isolate the video and ac3 stream with ffmpeg -map 0:0 -map 0:4 -c copy to another mts file, which I can open in openshot and hear the correct audio, unfortunally with a one-second-lag between video and audio - vlc can play all audio streams of the video without problems - The output doesn't show any obvious errors or warnings The configuration is unmodified buster configuration:

How to find out what goes wrong?

I just installed OpenSuse for the first time in my life. I am trying to run some videos on it. But VLC throws an error VLC could not decode the format "h264" (H264 - MPEG-4 AVC (part 10)) I tried searching for some solutions but could not find any concrete solutions for it. I tried making an account on the Suse forums, but somehow cant get my new account to work. So I am asking it here. I have all the codec packs installed I think.

I heard that Netflix needs PlayReady 3.0, Widevine, HEVC 10 bits de/encoder, HDCP 2.2... to play 4K/UHD contents So I want to know if Linux support these technologies, and if Netflix support those Linux frameworks I want to know too, if Linux can't, if a VM with W10 can support as is those technologies so Netflix can play 4K medias, or if it can with some pass-through I know this question doesn't belong completely here but idk where it can belongs otherwise, considering that Netflix support place is the last place to ask that, considering that they don't want to hear about any non official method (and this is normal for a dev. to work hard and clean on supported method but not on unofficial ones). If you know better place doesn't hesitate to tell me

# background I have a bunch of video files that I would like to play on my roku through it's "Roku Media Player." However many of them simply do not appear in the list of available videos on my roku which would suggest they are not in the correct format. According to roku it supports the following formats: > The following file formats are supported: > - Video – H.264/AVC (.MKV, .MP4, .MOV) > - Audio – AAC (.MKV, .MP4, .MOV); MP3(.MP3, .MKV); WMA (.ASF, .WMA, .MKV), FLAC (.FLAC, .MKV), PCM (.WAV, .MKV, .MP4, .MOV), AC3/EAC3 (.MKV,.MP4. .MOV, .AC3), DTS (.MKV, .MP4, .MOV,.DTS), ALAC (.MKV, .MP4, .MOV, .M4A), Vorbis (.OGG,.MKV,.WEBM) > - Playlists –.M3U, .M3U8, .PLS > - Image – JPG, PNG, GIF (non-animated) > The following media formats are supported on Roku devices that support 4K > - 4K Video – H.265/HEVC (.MKV, .MP4, .MOV); VP9 (.MKV, .WEBM) > - 4K Video – H.264 (Roku Premiere, Premiere+, and Ultra only) > The following media formats are supported on Roku TVs and some Roku players > - Video – H.262 (.MKV) # issue Many, if not all, of the videos are using H.264 AVC1 as far as I can tell, this includes both the working and non working videos. Video and audio codec information seems mostly Greek to me so I'm not entirely sure what I'm looking at but below is a sample of both a working video and a non working video: ## working $ ffprobe 21\ Jump\ Street.mp4 ffprobe version 4.2.4-1ubuntu0.1 Copyright (c) 2007-2020 the FFmpeg developers built with gcc 9 (Ubuntu 9.3.0-10ubuntu2) configuration: --prefix=/usr --extra-version=1ubuntu0.1 --toolchain=hardened --libdir=/usr/lib/x86_64-linux-gnu --incdir=/usr/include/x86_64-linux-gnu --arch=amd64 --enable-gpl --disable-stripping --enable-avresample --disable-filter=resample --enable-avisynth --enable-gnutls --enable-ladspa --enable-libaom --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libcodec2 --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libjack --enable-libmp3lame --enable-libmysofa --enable-libopenjpeg --enable-libopenmpt --enable-libopus --enable-libpulse --enable-librsvg --enable-librubberband --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx265 --enable-libxml2 --enable-libxvid --enable-libzmq --enable-libzvbi --enable-lv2 --enable-omx --enable-openal --enable-opencl --enable-opengl --enable-sdl2 --enable-libdc1394 --enable-libdrm --enable-libiec61883 --enable-nvenc --enable-chromaprint --enable-frei0r --enable-libx264 --enable-shared libavutil 56. 31.100 / 56. 31.100 libavcodec 58. 54.100 / 58. 54.100 libavformat 58. 29.100 / 58. 29.100 libavdevice 58. 8.100 / 58. 8.100 libavfilter 7. 57.100 / 7. 57.100 libavresample 4. 0. 0 / 4. 0. 0 libswscale 5. 5.100 / 5. 5.100 libswresample 3. 5.100 / 3. 5.100 libpostproc 55. 5.100 / 55. 5.100 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '21 Jump Street.mp4': Metadata: major_brand : isom minor_version : 1 compatible_brands: isomavc1 creation_time : 2012-06-09T07:12:42.000000Z Duration: 01:49:37.66, start: 0.000000, bitrate: 1956 kb/s Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1920x816 [SAR 1:1 DAR 40:17], 1859 kb/s, 23.98 fps, 23.98 tbr, 96k tbn, 47.95 tbc (default) Metadata: creation_time : 2012-06-09T07:12:42.000000Z Stream #0:1(und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 93 kb/s (default) Metadata: creation_time : 2012-06-09T07:20:20.000000Z handler_name : GPAC ISO Audio Handler ##

Others have suggested converting from mp4 to mkv, or vice versa, or from one to the other and then back. I have tried this without any luck. Another post (which I can't seem to find now) I found suggested it may have something to do with the metadata such as cover art not being supported but I'm not even sure how to see that information and as far as I can tell it doesn't exist on at least the above example. # question What ffmpeg command can I use to make the non working file more similar to the working file in hopes that it will be supported by my roku?

Say a song is recorded somewhere on the planet with a computer, and that stream of data is stored. If this is stored using Audacity , you can set it to .aup format, which is a very simple XML file. Why do we need anything else than a few data points in a file? Why would we use .mp3 or anything? In fact, encoding this increases the size for a few local samples. I think the issue could be size for images for example, but I can't say that for audio files.

I have converted a video of mine with ffmpeg into H265 codec. Great: Much smaller at the same quality. But then I noticed the video is blocky. I thought there was an error during re-coding. But no: I noticed that it gets blocky if I run other programs than VLC. I looked at how much of the CPU is required: 16% with the old codec, 60% with H265. So: Is H265 too demanding for me, since my computer (from 2013) is too weak?
