Currently running 9.0.0 on a C2, though I’ve noticed for a while now that sometimes after a commercial break watching FX using liveTV that the audio and video will be far out of sync. If I skip back a few seconds, it fixes itself. I finally managed to capture a small sample that demonstrates the issue and that is reproducible:
Playing back on my PC with mplayer, there seems to be a problem spot around 10 seconds in when the commercial changes:
[ac3 @ 0x7fd60b3a18c0]exponent -2 is out-of-range
[ac3 @ 0x7fd60b3a18c0]error decoding the audio block
Playing back the same sample file on an RPi with Kodi 18 doesn’t exhibit the problem, so the issue appears to be specific to amlogic decoding. Since the TV stream is coming from my cable provider and/or FX, the real issue may be with the data in the stream but I’m hoping the problem can be worked around since it plays fine using mplayer and on RPi.
