MPV media player in BionicPup64 won't play .mkv files

[bigphil]

Hi all,

I'm running Bionic 64 bit version, frugal install, and as the subject states, I can't get .mkv files to play.
As well as MPV I've tried several VLC players, one from Quickpet and Mikes one here -
viewtopic.php?f=88&t=153&p=6056&hilit=mkv#p6056.
None of them work.
However if I boot into Windoze and run it's VLC they play OK.

Any of you clever people got any ideas.

Regards
Phil

hi @bigphil

try running mpv in in a terminal

Code: Select all

mpv /path/to/my/video.mkv

[taersh]

It seems there is different .mkv versions existing. I also have this problem on some .mkv videos. Though, some of them playing fine. I think I can recall an error message like playing mpeg4-2 not supported.

a link to a problem mkv would be could if you're happy to post a link to it

[taersh]

Yet I don't have a direct link, but some current videos I had downloaded and there wasn't an option to download .mp4 or .webm.
These videos are .mkv videos that won't play video, but playing audio only.

Error message from VLC is (codec not supported):

Codec wird nicht unterstützt:
VLC konnte das Format „av01“ (AOMedia's AV1 Video) nicht dekodieren

Search YouTube for these videos:

Heilung Berserker's Songs
1 Hour of Dark & Powerful Viking Music
Danheim Skapanir (Full-album-2020)
Heilung LIFA

Here's a sample video with this AV1 codec: https://github.com/SPBTV/video_av1_samples

Just checked and it plays fine in Fatdog with VLC and ffplay.
We have libaom preinstalled and VLC/ffmpeg linked against it.

MKV is the container and is able to contain almost every codec. A missing codec is mostly the reason if a player doesn't play the video.
Here a link to a video with mpeg-4 part2 codec in a mkv container.

In my case mpv is playing this video.
Check your ffmpeg version.

Libaom seems not to exist in Bionic repositories.
Only Focal, but it complains about GLIBC_2.29 not found when installed into Bionic.
Needs to be compiled from source - if possible for Bionic?

@norgo
The video plays fine here.

@JakeSFR
The video doesn't play here.
Only the audio bip bop is playing.

Libaom seems not to exist in Bionic repositories.

Just in case, try a search in ppm for "av1" if you didn't do yet.

@JakeSFR
The video doesn't play here.

Same problem here. It said something about a video codec problem BUT real problem was it got downloaded wrong (95KB was reported the first time. Second time the file size was 240KB and now it worked ok with mpv).

Personally, I'd give norgo's SMPlayer builds a look. I've never had the slightest issue with playing anything in these. (May need to install mPlayer from the repos, if it's not already installed.)

I would, however, endorse what's been previously stated on this thread. Check ffmpeg! Puppies often come with older/stripped-back variants of this, so it's worth seeing if you can update it.... John van Sickle's static builds are highly recommended. (You may need to search the "old releases" to find a date-sympathetic version for the age of your Pup, however; despite being 'statically-compiled', the newest versions can still sometimes complain about stuff missing that's needed.)

It's solved several issues for me over the years. Curiously, Bionicpup64 has thrown up a LOT of issues for me; things that worked fine in earlier Pups have refused point-blank to play ball with this one.....and have then inexplicably started working again in later Puppies. Weird.

Mike.

Installing the static build of ffmpeg doesn't change anything on that issue.
VLC still plays audio only.

av1 test

at first I compiled aom from source
after that ffmpeg with option --enable-libaom

huge effort for a rare codec

[666philb]

using a combination of this PPA and the PPM you can update mpv & ffmpeg in bionicpup and get av1 working https://launchpad.net/~mc3man/+archive/ ... /+packages

[taersh]

There's two different ffmpeg in the ppa and there's two different mpv in the ppm.
Which files to download to get this to work?
Does this need libaom also?

[bigphil]

Oh dear - gloom and doom.
Installed mpv - 2:0.30.0~vs~bionic from the PPA suggested by 666philb and updated ffmpeg (to the best of my knowledge) and now MPV won't run at all.
Attempted to run it from the terminal and it reported -

mpv: error while loading shared libraries: libshaderc_shared.so.1: cannot open shared object file: No such file or directory

attempted to run ffmpeg from terminal and it reported -

ffmpeg: error while loading shared libraries: libmysofa.so.0: cannot open shared object file: No such file or directory

Unfortunately I don't have the knowledge to know how to proceed.

[666philb]

you'll need shaderc from the ppa and quite a lot of other stuff. running in a terminal will show what you need. there's also a few bits from the ppm if not in the ppa

[taersh]

Sounds like a solution not being a solution for real.
At least nothing being easily accomplished...

[666philb]

this seems to work.

open /var/packages/woof-installed-packages and delete the ffmpeg & mpv lines
then in a terminal

Code: Select all

pkg add-repo ppa:mc3man/bionic-media ubuntu bionic

Code: Select all

pkg repo bionic-mc3man

Code: Select all

pkg get ffmpeg mpv libcodec2 liblilv libpostproc

[bigphil]

Above didn't work for me I'm afraid.

However when I entered the second terminal command it reported -

root# pkg repo bionic-mc3ma
The name 'bionic-mc3ma' is not a valid repo name. These are:
bionic-mc3man
noarch
common64
xenial64
tahr64
bionic64
bionic-main
bionic-universe
bionic-multiverse

Maybe it's time for me to admit defeat but thanks anyway 666philb

[666philb]

@bigphil
oops .... spelling mistake on my part

Code: Select all

pkg repo bionic-mc3man

will fix my post

[bigphil]

stranger and stranger
ran pkg repo bionic-mc3man in terminal and it reported -

root# pkg repo bionic-mc3man
The name 'bionic-mc3man' is not a valid repo name. These are:
bionic-mc3man
noarch
common64
xenial64
tahr64
bionic64
bionic-main
bionic-universe
bionic-multiverse

and yet it states that bionic-mc3man is a valid repo name

????????

[rockedge]

I see this also from time to time. What I do in this case is highlight the repo name from pkg repo-list and then type in the terminal pkg repo and then I paste the repo name in.
For some reason it will then use it correctly.

After replacing the installed ffmpeg by the new one, KdenLive won't extract audio from video files anymore.

[OscarTalks]

I think we really need to know what the codecs are in the .mkv files that are not playing for original poster bigphil.
I would normally use ffinfo for this, but don't think it is installed.
The .mkv files which I tried did work in MPV. I notice that BionicPup64 does not have libmatroska, but this probably won't help with MPV. If it was a missing dependency, MPV would not start at all. There is a chance that it might help with VLC. I found this when compiling VLC in FossaPup, but VLC uses plugins whereas MPV does not as far as I know. Matroska is better at demuxing than relying on ffmpeg libraries if you want a wider range of codecs to play.

[bigphil]

@rockedge

tried that but still no go.

[666philb]

After replacing the installed ffmpeg by the new one, KdenLive won't extract audio from video files anymore.

just tried this with an avi and it worked for me. maybe run kdenlive in a term and see the error.
most likely some extra ffmpeg stuff missing from https://launchpad.net/~mc3man/+archive/ ... hive-extra
