FFmpegWrapper error during long registration

[Arlem]

@JajuanWang I solved (this) problem! Open FFmpegWrapper.c, go to line 420 and modify the code from:

packet->pts = (int) jPts;

to:

packet->pts = (int64_) jPts;

Then, recompile the FFmpeg library and wrapper with

sudo ndk-build.sh

and copy the generated library in the correct folder of your project.
I've done registration for more than 1 hour with this change.
I have checked that the error originates from jPts being a jlong, which overflows when casted to int (at around 35-40 minutes).
I don't know why it was casted to int, since pts is int64_t (as described by https://ffmpeg.org/doxygen/2.8/structAVPacket.html).

Just a small update, I have made more tests and can now exclude that the size of the data written (1.5GB) or the number of .ts files are the culprit; all registration stopped at approximately 40 minutes, as before.
Since it is a problem with FFMPEG, I will try to compile the newer version and go ahead from there.

[Arlem]

I updated FFMPEG to version 2.7.1, no differences encountered.

@OnlyInAmerica Have you got a chance to look into this?

[gouravd]

@Arlem I am having a hard time building FFMPEG 2.7.1 with rtmp. WOuld you be able to help? I want to use the native rtmp instead of librtmp.

I am able to separately build ffmpeg, openssl (using a different method than guardianproject's). I am not able to build librtmp. I am looking for a script that can build librtmp with my generated openssl. Any help would be appreciated

[JajuanWang]

@Arlem I have also encountered this problem.Stoped at approximately 35 minutes every time.To reproduce the bug running at least 35 minutes.
Have you solved it? Looking forward to your reply，thanks

[JajuanWang]

Working properly before approximately 35 minutes, but after about 35 minutes it stop recording and log that:
08-27 23:58:05.158: E/FFmpegWrapper(28230): av_interleaved_write_frame video: 1 pkt: 60493 size: 8892 error: Invalid argument

[Arlem]

@gouravd Sorry, I am using hls and haven't tried to build FFMPEG 2.7.1 with rtmp.
@JajuanWang No solution found, do you have any guess?

[JajuanWang]

@Arlem https://github.com/OpenWatch/FFmpegWrapper-Android/blob/master/FFmpegWrapper/jni/FFmpegWrapper.c on line 413 //packet->pts = av_rescale_q(packet->pts, *videoSourceTimeBase, (outputFormatContext->streams[packet->stream_index]->time_base));I was going to comment this line，because i need not to adjust the time base,I guess the problem is caused by the this.I have tried to verify it，but recompile the .so files failed

[JajuanWang]

@Arlem and you can see the link http://www.ffmpeg.org/doxygen/2.0/mathematics_8c_source.html on line 130 int64_t av_rescale_q(int64_t a, AVRational bq, AVRational cq),I just known it is used to adjust the time base

[Arlem]

@JajuanWang It fails when you run ndk-build.sh or build_ffmpeg_for_android.sh?

[dyoungjr08]

I have FFmpegWrapper.so and cant view or edit it. what would be the solution in this case. Thank you.

[dyoungjr08]

@Arlem can you please share the corrected and updated. .so files. Thank you

[Arlem]

@dyoungjr08 This is my .so file of the FFmpeg wrapper (for armeabi and armeabi-v7a).
libFFmpegWrapper.zip

Tell me if you need the other FFmpeg library also.

By the way, have you seen this project? https://github.com/OnlyInAmerica/FFmpeg-Android you might need to recompile on your own in the future.

[dyoungjr08]

Thank you. I believe I do need the others. Im getting this crash now when I try and start a stream:

@dyoungjr08 These are the ones I am actually using. Let me know if they work
