Mpv: comfirm mpv is compiled using ffmpeg and not Libav

[LandisTwo]

mpv version and platform

mpv 0.22.0 built on Nov 20 2016
installed from Packman for OpenSuSE 13.2
If you're not using git master or the latest release, update.

Reproduction steps

mpv docs say to use ffmpeg and Not Libav as some options are not available with libav.

mpv --version

mpv 0.22.0 (C) 2000-2016 mpv/MPlayer/mplayer2 projects built on Nov 20 2016 ffmpeg library versions: libavutil 55.17.103 libavcodec 57.24.102 libavformat 57.25.100 libswscale 4.0.100 libavfilter 6.31.100 libswresample 2.0.101 ffmpeg version: 3.0.4

Expected behavior

I would think that there would be no 'libav' files if mpv were using ffmpeg and Not Libav.

Actual behavior

How can I verify this binary from Packman repo is using ffmpeg and not libav
I'd build it myself, but There are SO many other files (gstreamer, ffmpeg libraries, codecs etc) that I'd rather not. I've installed mpv, smplayer Many times on OpenSuSE over the years on Many systems that I know the littlest file, library version can cause many problems. I'd like to stick to the binary.

Log file

Thankyou for producing mpv... It & it's predecessor mplayer have made using Linux over the past many years, much nicer. Thanks. Landis.

Make a log file made with -v or --log-file=output.txt, paste it to

Providing a log file is strongly encouraged. It is very helpful for reproducing
bugs or getting important technical context. Without a log it might not be
possible to analyze and fix certain bugs.

libav* are the libraries' names. They were named that way before the libav fork.

The definitive way would be to check ldd $(which mpv) | grep libavcodec, then look up that filename in your package manager's installed packages, e.g.

λ equery b /usr/lib64/libavcodec.so.57
 * Searching for /usr/lib64/libavcodec.so.57 ... 
media-video/ffmpeg-9999 (/usr/lib64/libavcodec.so.57 -> libavcodec.so.57.66.103)
media-video/ffmpeg-9999 (/usr/lib64/libavcodec.so.57.66.103)

That's not very definitive. Just look at the micro version numbers - if they're below 100, they're Libav.

You could:

1. Check PMBS
2. Grab the source RPM
3. Ask on the Packman mailing list
4. Look at mpv’s version output (it actually prints “libav” instead of “ffmpeg” if it looks like it’s built with Libav library versions)

haasn - thanks I'll look.
mine looks like this:
libavcodec.so.57 => /usr/lib64/libavcodec.so.57 (0x00007f24e4dab000)

wm4 - so, Libav (big L) are the libraries mpv docs say limit options, right.
Where libavxxxx (small L) are ffmpeg files and should have micro version above 100? like mine: libavutils 55.17.103 or libavcodec 57.24.102,, 103 and 102 being above 100, so NOT Libav (big L), yes?

Thanks.
Landis.

if I do ffmpeg -version mine looks like this... presumably Libav libraires, yes?
libavutil 55. 34.100 / 55. 17.103 libavcodec 57. 64.101 / 57. 24.102 libavformat 57. 56.100 / 57. 25.100 libavdevice 57. 1.100 / 57. 0.101 libavfilter 6. 65.100 / 6. 31.100 libavresample 3. 1. 0 / 3. 0. 0 libswscale 4. 2.100 / 4. 0.100 libswresample 2. 3.100 / 2. 0.101 libpostproc 54. 1.100 / 54. 0.100 landis@linux-e6420:~> mpv -version mpv 0.22.0 (C) 2000-2016 mpv/MPlayer/mplayer2 projects built on Nov 20 2016 ffmpeg library versions: libavutil 55.17.103 libavcodec 57.24.102 libavformat 57.25.100 libswscale 4.0.100 libavfilter 6.31.100 libswresample 2.0.101 ffmpeg version: 3.0.4

What 'options' am i missing if my binary is compiled using Libav instead of ffmpeg? I haven't come across anything I want to do, that I have not been able to do.

I see you're on irc.. I'll ask there. Thanks.

guys - it's not really that important to me.
mpv works now and i don't produce video, so as long as it plays i'm good.

I was having an issue where mpv would crash, but only after movie/video was paused for a long time, then resumed and the log kept saying the shared version of ffmpeg is not the same version mpv was compiled against.

Well, that is almost Always going to be the case. Many apps, especially something like youtube-dl which is updated almost daily will stop working if the ffmpeg version becomes 'too old' and ffmpeg needs to be updated.
Eventually I'll be right back at ffmpeg is not the same ver mpv was compiled with... right.

So, it's working at the moment, but I haven't tried youtube-dl to see if ffmpeg version is 'ok with it'.

Thanks for your time, maybe i'll see you on irc.
Landis.

It really shouldn’t be. That is a packaging problem.
