LibVLC complains about missing codec (h264)

[Glandos]

When trying to play https://www.youtube.com/watch?v=3J06af5xHD0 here is the output:

(Sorry for the French inside…). However, when I try to play it with VLC on the same machine, everything is working fine.

Is there something I can do to know why libvlc is not working and vlc does the job?

I'm using Debian/unstable with MotionBox 1.6.0-6.

Here are some relevant logs from VLC itself when playing the same video:

So maybe ffmpeg is not used/detected?

Oh wow, never encountered something like this. Can you confirm you have no libvlc.so in your MotionBox folder and you start things with start.sh ?

[Glandos]

user@complexe ~/T/MotionBox-1.6.0> pwd
/home/user/Téléchargements/MotionBox-1.6.0
user@complexe ~/T/MotionBox-1.6.0> find -name '*libvlc*'
user@complexe ~/T/MotionBox-1.6.0>

And yes, I start it with sh start.sh. Note however that it is working with https://www.youtube.com/watch?v=hsxukOPEdgg because it's AV1 at 480p. I was using 480p for the failing stream also.

Strange, what's the VLC version on your Debian ?

[Glandos]

The current version on unstable : 3.0.11.1-1

[kodxana]

Having that same problem :P

[3unjee]

@kodxana What distribution / version are you using ?

Could you guys try this artifact (Linux 64 bit): https://dev.azure.com/bunjee/MotionBox/_build/results?buildId=2239&view=artifacts&type=publishedArtifacts

This could be related to this: http://omega.gg/t/some-youtube-videos-dont-start/100/15

[kodxana]

@3unjee Yup this artefact works perfect. Pop_OS! 20.04 64bit

[Glandos]

It also works here!

[JimboJoe]

I confirm the above-mentioned artifact fixes the problem on Linux Mint 20 👍

[3unjee]

OK, I'll push the new version ASAP and close this.

I am also facing the same issue that libVLC is not able to play video whereas VLC does.
I am using UBUNTU mate 20.04.1 LTS on raspberry pi 4.

[0000ffff60035af0] main decoder error: Codec `h264' (H264 - MPEG-4 AVC (part 10)) is not supported.
[0000ffff60035af0] main decoder error: Codec not supported
[0000ffff60035af0] main decoder error: VLC could not decode the format "h264" (H264 - MPEG-4 AVC (part 10))

Can someone please help me

[3unjee]

That shouldn't happen on Ubuntu 20.04 with VLC installed, have you tested the lastest archive -> https://omega.gg/MotionBox/get ?
