Thanks, Ravi. I will have a look at updateclock.
The crash eventually lies in video decoding thread but before that, I find
GetCurrentTime64 returning unreasonable data.

Have you tried logging the android_audio_mio.cpp ... function:
AndroidAudioMIOActiveTimingSupport::UpdateClock(). Check if the clock
value is overflowing.
Also, when you did see a crash, did you get a stack trace, or do you
know where it is crashing?

My video clip is 80min but it crashed sometime in the mid of somewhere,
and
othertime after 1-2 round playing. But According to Dave, it was 5 Hrs. I
thought this might be different due to hardware platform.
Do you have any idea of this?

How long is the long duration?

Hi all esp. PV engineers,
I am working on a hard bug found during long duration video playback
by
OpenCORE v1.0 and it hangs mediaserver.
I find an extremely old email talking about bugs related to long
duration
avsync playback of opencore by Dave Sparks. It seems to be about
OpenCORE
v1.0. I'd like to know the details about this bug, e.g. description
and
root
cause and workarounds? Thanks.
Please refer to the following statements by Dave Sparks. Thanks.

The audio MIO counts the number of audio samples output to the
audio
sink and divides by the frame rate. This value is adjusted by the
latency reported by the audio sink (which ultimately comes from the
audio HAL plus the latency in the software mixer engine). For some
reason with OpenCore 1.0, we could never reconcile the real
hardware
latency with the presentation of video frames in the MIO, so we had
to
add a fudge factor. We are hoping that OpenCore 2.0's new media
playback clock will resolve this issue.
I think there is an outstanding bug related to the playback clock
and
long streams, but I seem to recall that was 5 hours. For most
mobile
devices, the battery is going to die long before that if the DSP
and
backlight are powered up the entire time.
