Re: Media server died

This problem can happens when you are using encrypted TS chunks data. Is your stream data has strongly decrypted mpeg2-ts chunk?

I recently experience this on a Verizon Galaxy Nexus running 4.2.2.

I tracked this down in the Android source.

The call to CHECK_EQ( sync_byte,0x47u) is made in:  ATSParser.cpp

CHECK_EQ is defined in:   ADebug.h

It appears this is calling assert to cause a fatal error.

Question for Android dev team:  Why in production code is there an assert?

Hi,

I'm using OpenMAX AL to design a MediaPlayer.

I'm using a Jelly Bean device (4.1.1).

After a few seconds, I have a crash in libstagefright (see attached logcat traces).

Here is a short extract of the traces:

04-04 08:10:26.281: A/ATSParser(10915): frameworks/av/media/libstagefright/mpeg2ts/ATSParser.cpp:1187 CHECK_EQ( sync_byte,0x47u) failed: 70 vs. 71

My problem is that the same application runs without any issues on ICS devices.

Does it ring a bell to anyone?

I have looked at the code you linked (and code it calls) and I can't find an asset in there.  Can you link the file with line number where you think the assert is getting invoked?

[Peter Tran]

I believe this is the call sequence:

  CHECK_EQ ==> CHECK_OP ==> LOG_ALWAYS_FATAL (ADebug.h line 67)

    LOG_ALWAYS_FATAL ==> android_printAssert (platform/system/core/include/cutils/log.h line 301)

      android_printAssert ==> __android_log_assert (platform/system/core/include/cutils/log.h line 442)
