In particular I'd like a command for mpv that will automatically play youtube links I add in order. For example, at a party I might want to queue up songs as we think of them, and have them automatically play.

For some reasons, I can't get to play certain mp4 files downloaded from Microsoft Teams. It could play those files, but it started crashing randomly. I'm on arch linux and I suspect it is because of an update, so here's all the packages I updated before I started getting this problem: - alsa-card-profiles -> (1:1.2.7-1) - htop -> (3.3.0-3) - libx11 -> (1.8.11-1) - imagemagick -> (7.1.1.44-1) - libpipewire -> (1:1.2.7-1) - libsm -> (1.2.5-1) - libsynctex -> (2024.2-6) - linux -> (6.13.5.arch1-1) - pipewire -> (1:1.2.7-1) - pipewire-audio -> (1:1.2.7-1) - pipewire-session-manager -> (1:1.2.7-1) - pipewire-alsa -> (1:1.2.7-1) - pipewire-jack -> (1:1.2.7-1) - pipewire-pulse -> (1:1.2.7-1) - xorg-xauth -> (1.1.3-1) I tried playing different files and different mp4 and they all worked, but I really need to get mpv working again with these files. I tried installing mpv-git from the AUR, but it didn't help. Do you have any idea what could be the problem? Let me know if specific command outputs are needed to have a better insight of the problem. Here is some more info and clarifications: - The exact same file can be played on the same exact machine with vlc. - I tried redownloading the file and also tried different files downloaded from MS Teams and they all stopped working on this machine. - Here is the crash dialogue from mpv:

61624 segmentation fault (core dumped)  mpv Video/Lezione\ 8\ -\ 08_03_2023.mp4

- The same files can be played on a different machine with mpv. This other machine uses Ubuntu with mpv version 0.34.1, while the machine where files are not playing uses mpv 0.39.0. Here is the output for mpv -version on the machine where files are not playing correctly:

## "Solution" ## I find out that using mpv --ao=alsa file.mp4, the problem does not occur, so it seems to be caused by the recent updates to pipewire. ## Actual solution ## Most recent update for pipewire and related packages solved the issue.

I've been using mpv for a while, but now whenever I try to play a youtube video the following output shows up: [ffmpeg] https: HTTP error 403 Forbidden Failed to open https://rr5 . . . EDL: Could not open source file: 'https://rr5 . . .' No video or audio streams selected. Oddly, I can play videos on other platforms, such as Odysee and Rumble. I've looked for answers in this substack and elsewhere and haven't found a solution for this specifically.

I want to compare two videos (with different resolutions) and want to go though both videos frame by frame (forward and backward) in sync. I managed to do so using

mpv somevideo720.mkv --external-file=somevideo1080.mkv --lavfi-complex='[vid1] scale=960x540 [vid1_scale]; [vid2] scale=960x540 [vid2_scale]; [vid1_scale][vid2_scale] hstack [vo]'

(compare [here](https://github.com/mpv-player/mpv/issues/3854#issuecomment-571424357)) However I also want to set up two different starting positions of the videos. How can I do this without modifying the videos itself? The best solution would be if it would be possible to open both videos, navigate in both videos to the desired starting position, then go into "sync mode"...

I prefer streaming Youtube videos via mpv, mpv https://www.youtube.com/watch?v= However, for long videos sometimes the audio breaks down in the middle, leaving error messages like > [ffmpeg] tls: Error in the pull function. Restarting the video is starting it from the beginning. How can I either directly in the command line start from, let's say, minute 30, or alternatively jump in the mpv interface to minute 30 *without* pressing 30 times the up button (which also has issues if done too fast)? I haven't found an answer related to that issue in the man page. Is it possible at all? Also alternative suggestions for streaming are welcome.

I have tried a combination of: * v4l2loopback * ffmpeg * mpv But either the web-cam view, or the web-cam record works, but never both together. Can anyone provide a script that achieves this? This is what I've tried so far:

#!/usr/bin/env bash

set -x

# This needs the video loopback module to be installed.
# sudo modprobe v4l2loopback devices=1 video_nr=10 card_label="VirtualCam" exclusive_caps=1

# use pw-cli list-objects | grep node.name to get the audio device
AUDIO_DEVICE="alsa_input.pci-0000_00_1f.3.analog-stereo"
VIDEO_DEVICE="/dev/video0"
VIRTUAL_VIDEO_DEVICE="/dev/video10"

read -p "Enter a name for the video: " VIDEO_NAME

if [ -z "$VIDEO_NAME" ]; then
    VIDEO_NAME="unnamed_video"
fi

OUTPUT_FILE="$HOME/videos/${VIDEO_NAME}_$(date +%Y%m%d_%H%M%S).mkv"

trap 'echo "Stopping recording..."; pkill -P $$; exit 0' SIGINT

ffmpeg -f v4l2 -framerate 30 -video_size 640x480 -i "$VIDEO_DEVICE" \
    -f v4l2 -video_size 640x480 -i "$VIRTUAL_VIDEO_DEVICE" &

sleep 2

# Start displaying the virtual webcam feed with mpv
mpv --no-osc \
    --no-input-default-bindings \
    --profile=low-latency \
    --geometry=50%:50% \
    --autofit=100% \
    --input-conf=/dev/null \
    --title='WebcamDisplay' \
    --framedrop=no \
    --vf=scale=640:-1 \
    --vo=vaapi \
    "$VIRTUAL_VIDEO_DEVICE" &

# Start recording from the virtual device with ffmpeg
ffmpeg -f v4l2 -framerate 30 -video_size 640x480 -i "$VIRTUAL_VIDEO_DEVICE" \
    -f pulse -i "$AUDIO_DEVICE" \
    -c:v libx264 -preset ultrafast -crf 28 -pix_fmt yuv420p \
    -c:a aac -b:a 192k -ar 48000 \
    "$OUTPUT_FILE"

# Stop all processes when done
pkill ffmpeg
pkill mpv

This is my loopback setup:

$ v4l2-ctl --list-devices
VirtualCam (platform:v4l2loopback-010):
        /dev/video10

Integrated_Webcam_HD: Integrate (usb-0000:00:14.0-12):
        /dev/video0
        /dev/video1
        /dev/media0

I'm facing a peculiar issue. I've copied media file to USB flash (using Linux Mint). Now when this files is played by mpv at one point it freezes for some time displaying what looks like green foreign language symbols all over the screen (and no subtitles after unfreeze). When played from initial disk it plays fine. Hashes as calculated in terminal are same. I wonder how playing same file can lead to different results.

In mpv, there's the --start switch, which allows me to provide a number of seconds to skip. This way I can start playback at a random moment in a single file. And there's --shuffle which allows me to start playback at a random file within a given playlist. I combine both to: 1. choose a random file and 2. start playback at a random moment in that file with this command line:

mpv --shuffle --start $POSITION --playlist=/tmp/list.m3u

### Issue However, the --start parameter will be considered for each and every file that follows later on in the list as well and those will also have their first X seconds skipped. I don't want that. ### What I tried Currently I invoke mpv twice, in sequence, but that's ugly. ### Questions Is there a way to have --start only affect the very first file played? Or, even better, get mpv at a completely random moment in the random playlist. So, if the list is 123 minutes, it would start at 31 minutes 13 seconds, regardless of how far or not that would be into the file.

How can I control mpv in command line? Like is there a mpv next/prev command that I can use to play next or previous media file?

I start music or video with right click and "open with" in Thunar (Xfce). For every entry, there is a *.desktop file in ~/.local/share/applications or /usr/share/applications. I want to start an application with a pipe and save the output in a file. This works in terminal: mpv file.mp4 > log 2>&1 But that doesn't work when I add the same line to the desktop file: Exec=mpv file.mp4 > log 2>&1 The file is started, but there is no output. How can I do this? Is there something special when using desktop files? also starting with terminal=true, but that didn't work.

In my .bashrc I have a function which I use to play random videos (not written below, just fyi), and another one for all media files, e.g.: createmediafiles() { find ~+ -type f -iregex '.*\.\(mp3\|wav\|ogg\|flac\|mp4\|mov\|avi\)' > ~/mediafiles.txt find ~+ -type d -name VIDEO_TS >> ~+/mediafiles.txt } playmediafiles() { while true; do while read -r line; do shuf -n 1 | tee -a ~/played-log.txt | xargs -d "\n" mpv done < ~/mediafiles.txt done } I want to add the VIDEO_TS line to createmediafiles, but in the playmediafiles function I want to add an IF statement, such that if the line shuffled to in mediafiles.txt is a VIDEO_TS then rather than using mpv to play a file, it will do: tee -a ~/played-log.txt | xargs -d "\n" vlc --fullscreen Piping in mediafiles.txt read the same way as it does with mpv. How do I throw that in an IF statement with the condition being that the line ends in VIDEO_TS?

I'm trying to capture video from an Elikliv UVC microscope in Linux. We can do direct frame-by-frame capture using this command:

v4l2-ctl --device /dev/video0 --stream-mmap --stream-to=stream.mjpg

... and I can see it live using this big crazy command:

v4l2-ctl --device /dev/video0 --stream-mmap --stream-to=/proc/self/fd/1 | \
  ffmpeg -i - -fflags discardcorrupt -c:v copy -f matroska - | \
  mpv --profile=low-latency -

..but I can't get it to work directly with V4L2-aware software (ie, MPV, VLC, OBS) without the help of v4l2-ctl to stream it into ffmpeg and then mpv. ## **Question:** Is there a way I can tell configure the V4L2 device to work in a "normal" way, directly from /dev/video0, without a big crazy pipe? ## MPV says

# mpv /dev/video0
[lavf] avformat_open_input() failed
Failed to recognize file format.

## VLC says

Your input can't be opened:
VLC is unable to open the MRL 'v4l2:///dev/video0'. Check the log for details.

I have very limited data in a remote area and so I listen to youtube (and other video platforms) using

--no-video

. Does anyone know how to lower the audio quality so that I can reduce my streaming data usage even more? (most of what i listen to is just talk). I tried adding

=fast

in

.conf

but mpv didn't recognize it. I also searched through

mpv

but couldn't find what I wanted. I am using Linux Mint 21.2 UPDATE: Using the accepted answer and searching

mpv | grep ytdl

, I ended up with:

--no-video --ytdl-format=worstaudio/worst

This reduced data usage by almost half and as far as a podcast goes, there is little difference in listen-ablity.

I'm trying to play both front and rear footage from my dashcam at the same time as a playlist in mpv. Front and rear video files are in F and R directories. I can easily add all files from e.g. F directory to the playlist: mpv F/* I can also run a picture-in-picture overlay for a single pair of front/rear footage: mpv $front_video --external-file=$rear_video --lavfi-complex='[vid2] scale=640x360 [small]; [vid1] [small] overlay [vo]' I'm having trouble combining both, i.e. I want a playlist of picture-in-picture overlays. The issue is I always get the rear view from the first video: mpv \ REC_200607-175943F.MOV --external-file=../R/REC_200607-175943R.MOV --lavfi-complex='[vid2] scale=640x360 [small]; [vid1] [small] overlay [vo]' \ GSR_200607-180444F.MOV --external-file=../R/GSR_200607-180444R.MOV --lavfi-complex='[vid2] scale=640x360 [small]; [vid1] [small] overlay [vo]' \ GSR_200607-180943F.MOV --external-file=../R/GSR_200607-180943R.MOV --lavfi-complex='[vid2] scale=640x360 [small]; [vid1] [small] overlay [vo]' 1st overlay, all fine: 2nd overlay, plays rear view from the 1st one: For now I'm using a script that runs mpv for the next pair of videos as soon as the first one quits so I can watch all of them from start to finish but I miss the features like jumping to previous/next video, checking where in the playlist I am, setting a playback speed, volume, contrast, etc. Also, it's cumbersome to stop in the middle of playback because quitting one mpv instance runs the next one: #!/bin/sh for front in $(ls -tr); do rear=../R/${front/F./R.} mpv $front --external-file=$rear --lavfi-complex='[vid2] scale=640x360 [small]; [vid1] [small] overlay [vo]' done Any suggestions?

I have looked in mpv.conf and in input.conf and don't see any setting for subtitle font. I see size but not font name. However I see that it must be a configurable value because I have mpv running on two different machines and see they are different from each other.

Mpv is not loading and playing lyrics files, even though they're in the same directory with the same name but different .lrc file extension. and I even have the following in my mpv.conf file

.conf
autoload-files=yes
sub-auto=fuzzy

When using mpv to step through frames (. for stepping forward and , for stepping backward), the forward stepping rate is much faster than the backward stepping rate. The forward rate is about the same as the video frame rate (60fps for the video in question, which is an mp4 file prepared from a set of png images using ffmpeg with libx264 encoding) whereas the reverse stepping rate is about 1fps. Is there any way to control the stepping rates? Why would the forward/backward rates be so asymmetric? If an alternative video player is available for linux systems that supports variable (or at least equally fast) video frame stepping, please advise (mplayer is not better than mpv in this regard).

**tl;dr** how can I substitute a string (i.e. a youtube/streaming url) in an alias such as alias mpvyt='yt-dlp -o - | mpv - ' ? I live in a mezzanine studio using a M1 macbook for a workstation (writing/editing) and my old laptop with openbsd as a local server. I play music from that *obsd* server upstairs, which thus fills the whole room down to my desktop through the plugged-in speakers. My hosted library plays fine with [mpd](https://openports.pl/path/audio/mpd) and [ncmpcpp](https://formulae.brew.sh/formula/ncmpcpp) , and I just figured out it's not so difficult to [use mpv to play streamed youtube videos](https://www.reddit.com/r/mpv/comments/opoorx/comment/j7exh1n/) , since firefox in [XQuartz](https://www.xquartz.org/) streaming from [xenocara](https://xenocara.org/) is way too slow anyhow. I use a variety of different alias**\[1\]** as shortcuts to frequent commands, and [understand](http://sylvain.sab.free.fr/cestquoi/) [the basics of programming](http://sylvain.sab.free.fr/cestquoi/programmation/) but am an absolute beginner when it comes to [shell/ksh88 syntax](https://man.openbsd.org/ksh) . I would like to use a short command for streaming youtube videos from the obsd server which I connect to using ssh. The following : yt-dlp -o - | mpv - -force-seekable=yes works well but **how can I do something like alias mpvyt='yt-dlp %s -o - | mpv -' ** so that I don't have to type the full command ? I suppose it involves a **basic string substitution using the** **ksh88** **syntax** which I am clueless about ... **or** perhaps I need to go as “far” as to use **a little standalone shell script a.k.a snippet ?** To go further, a great bonus would be if I could stream playlists, as well as separate the video and audio streams so I can play the video on the workstation screen, I will look into the [mpv documentation](https://mpv.io/manual/) for this. **\[1\]** (you may skip this irrelevant block of code, I just copy-pasted my terminal output to brag about my network and aliases) Last login: Tue Oct 31 06:54:34 on ttys002 sylvain@sylvainmac ~ % more /etc/hosts ## # Host Database # # localhost is used to configure the loopback interface # when the system is booting.

For e.g. I have this sort of subtitle 1 00:01:55,201 --> 00:01:58,401 It's absurd going to school every day. The school's closed today. Now I'm unable to figure out the font color. Is there a way to get the color chart or give names or something that makes it clear what the color of the sentence is ?

I'm tracking several GitHub repositories, from which I often fetch configuration files for tools like mpv and hyprland. Given that these repositories frequently receive updates, I'm seeking a more efficient process to pull the latest changes without manually inspecting each repository and merging with my custom changes. **Current Process**: 1. Subscribe to changes on these repositories. 2. Manually download the updated config files. 3. Compare old and new config files (figure out what thing i chaged in which config, which was changed by developer) 4. Resolve conflicts manually. 5. Repeat this cycle. **Repositories** (for reference, there are many more): - - - - - This problem isn't new but i can't find any reference to this. Maybe i can't phrase it correctly.Does anyone have any strategies, scripts or tools help streamline this process? I'd like to be able to easily pull updates, see differences, and manage conflicts more efficiently.
