Was this in normal playback, time stretch or fast forward? AFAIK the
IllegalStateException that the sledge hammer handles only happens in
fast forward or occasionally in skip/jump. (i.e. when flush is
used).<br>

According to mediacodec documentation, IllegalStateException only
happens on dequeue output if the decoder is not executing or it is
in asynchronous mode.<br>
<br>
It is not in asynchronous mode or dequeue output would never work.<br>
<br>
The ways it can stop executing are if you call "stop" or "reset" or
"release" it. In ffmpeg there is a "stop" routine but it is never
called, and there is no reset routine. It seems that there is no
way to get into a non-executing state. Prehaps it is in an error
state. Unfortunately there is no native API that will tell you the
state.<br>
<br>
It seems that this may be a bug in mediacodec on the shield. I don't
know how much I should do to try and work around it. I have tried
reordering calls and adding a stop and start after the flush, but
nothing has helped.<br>

. Kodi doesn't use ffmpeg (AFAIK) for MediaCodec. I don't know about
Plex.

Perhaps I need to report this to NVidia<br>
