[packman] HandBrake on Leap 15.3 does not produce hearable audio tracks

[Manfred Hollstein]

Hi there,

I normally use HandBrake to convert AV recordings from my Dreambox into
a format to keep on my local server. Doing this on Leap 15.3 produces a
video which can be seen, and it also produces audio channels which are
shown normally using e.g. "mpv" - however, the audio is not hearable,
it's just silent.

Trying to playback that file using "vlc" then shows:

$ vlc S01E05.D\303nnes\ Eis.mkv
VLC media player 3.0.13 Vetinari (revision 3.0.12.1-158-g6977abc430)
[0000555864925f90] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.
[0000555864a09f30] main audio output error: too low audio sample frequency (0)
[00007fc0ccd0de10] main decoder error: failed to create audio output
[00007fc0b4007020] gl gl: Initialized libplacebo v2.43.1

libva info: va_openDriver() returns 0
[00007fc0ccc35ee0] avcodec decoder: Using Intel iHD driver for Intel(R) Gen Graphics - 20.3.0 () for hardware decoding

Note the "main audio output error: too low audio sample frequency"! I
guess this is the reason why there is no audio. Trying to play back the
same file on Leap 15.2 does not change anything, so the issue is caused
on the conversion side, i.e. on Leap 15.3. Using the same preset on Leap
15.2 I get a fully functional video with hearable sound! AFAICS, the
main difference between Leap 15.2 and 15.3 is ffmpeg-4.2 vs. ffmpeg-4.4.

Did anybody see similar issues on Leap 15.3? Or, is anybody able to
create working audio streams using ffmpeg-4.4 based AV tools?

TIA, cheers.
