Failed to initialize a decoder for codec 'av1'. #135

Closed mrkapqa closed 4 years ago

mrkapqa commented 4 years ago

Hello,

i built mpv with vaporsynth support according to these instructions here

https://www.svp-team.com/wiki/SVP:Linux

echo --enable-libx264 >> ffmpeg_options echo --enable-vapoursynth >> mpv_options echo --enable-libmpv-shared >> mpv_options ./rebuild -j4 sudo ./install cd ..

now when playing some video through youtube-dl-hook+mpv i got the error

mpv https://www.youtube.com/watch?v=Dt-PEVm8754 (+) Video --vid=1 () (av1 1280x720 29.970fps) (+) Audio --aid=1 --alang=eng () (opus 2ch 48000Hz) Subs --sid=1 --slang=en 'vtt' (webvtt) (external) Failed to initialize a decoder for codec 'av1'. Video: no video

could you please show me which options i would need to get full ffmpeg support here?

Thank you very much.

install libdav1d and --enable-libdav1d in ffmpeg_options

thanks!

in ubuntu 20.04 there is only "libdavix0v5" under "libdav*" that won't be the right package i assume?

mrkapqa commented 4 years ago

on ubuntu 20.04 could not get libdav1d to install

1.option here

https://snapcraft.io/install/dav1d/ubuntu

would not install libdav1d and error is ERROR: dav1d >= 0.4.0 not found using pkg-config

  1. option here

https://code.videolan.org/videolan/dav1d/-/wikis/compilation-guide

after ninja one is supposed to add ninja install which on my computer fails

error has been solved; has been onmy part - thank you.

mrkapqa commented 4 years ago

however, after

ninja install

[1/2] Installing files. Installation failed due to insufficient permissions. Attempting to use polkit to gain elevated privileges...

and afterwards building mpv with these options

echo --enable-libx264 >> ffmpeg_options echo --enable-vapoursynth >> mpv_options echo --enable-libmpv-shared >> mpv_options echo --enable-libdav1d >> ffmpeg_options ./rebuild -j4

would still result in

thank you, this has been solved by adapting

$PKG_CONFIG_PATHto whatever is the location thatninjainstalleddav1d.pcto, in my case/usr/local/lib64/pkgconfig/(i.e.export PKG_CONFIG_PATH=/usr/local/lib64/pkgconfig`).
