Ever since switching from Windows to Linux, I have been unable to render any videos in Blender's VSE with the audio tracks.

The audio codec is selected in the scene tab: The "Output" tab in Blender's properties panel. The container is set to MPEG-4. The video codec is set to H.264, and the audio codec is set to AAC.

However after rendering with Render > Render Animation the created file has no audio data whatsoever. ffprobe gives this result:

$ ffprobe -i wheel.mp4
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'wheel.mp4':
    major_brand     : isom
    minor_version   : 512
    compatible_brands: isomiso2avc1mp41
    date            : 2020/08/13 09:38:02
    encoder         : Lavf58.49.100
  Duration: 00:00:06.67, start: 0.000000, bitrate: 5835 kb/s
    Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9], 5832 kb/s, 30 fps, 30 tbr, 90k tbn, 60 tbc (default)
      handler_name    : VideoHandler

When I attempt to render the audio on it's own via Render > Render Audio > Mixdown, Blender crashes without a log file regardless of how I attempt to mixdown the file.

This is happening regardless of my choice of rendering engine, and I don't think it's an out of memory error since I have plenty of available memory before the crash and the video portion renders fine.

Has something changed between rendering files from the VSE between 2.7 and 2.8, or is there something I don't know about rendering audio in Blender on Linux that's causing a crash?

  • $\begingroup$ I've had a few issues with blender on non-ubuntu based distros that were all solved by using the tarball on blender's website as opposed to the repos. $\endgroup$

  • $\begingroup$ Fedora (and probably other red-hat based distros) don't have support for ffmpeg non-free libraries out of the box. blender.stackexchange.com/questions/28681/… $\endgroup$

  • $\begingroup$ Those are fair comments. I'm running Manjaro, and using Blender from the Arch package repository. I'm not sure if this is specifically a problem with using nonfree codecs because I had this issue with VP9/Vorbis as well. I'll try with the official tarball and report back. $\endgroup$

  • $\begingroup$ I'll be darned, that worked right out of the box. I'll go ahead and answer my own question I suppose. $\endgroup$

After a few comments on the above post and some experimentation, it seems not all distro packages are created equal. If you're experiencing some weird bugs like this, try downloading a tarball right from Blender.org.

  • $\begingroup$ Packages from repositories are not created by the developers of blender, so go figure how they are compiled and what is included or left out. $\endgroup$
