Maybe there is no way out of reverting the commit upstream ?
I see no reports about this issue in
https://trac.ffmpeg.org/search?q=kodi. Could you forward the issue to
the ffmpeg upstream bug tracker ?
If you cannot or do not have the time to open an ffmpeg upstream bug
report, tell me I will open an upstream bug, but I just do not know yet
how to bind such an upstream bug report to Debian BTS.
PS: I have a setup that can reproduce the issue (Kodi + NextPVR) so I
may be able to test code if that is requested by upstream. Though I do
not know Kodi internals.

The author of the code is Andreas Rheinhardt. Do you want to forward
your email to him too ?
All in all I believe this material for the ffmpeg bug tracker not
personal emails.
