Hello,
I noticed that some streams are being closed in the last branch of ffmpeg
2.5.x. THE SAME DIDN'T HAPPEN in 2.4.x and probably in the previous
versions as well.
I don't know the real reason of it since ffmpeg does not output any error,
it just closes without a reason.
It's not a stream problem 10000%, since exactly THE SAME TIME i tried with
FFmpeg 2.4.5 and it works perfect. I also started the streams multiple
times to ensure that it is a bug.
I tried it with the latest git version, and same happens so i will just
use the FFmpeg 2.5.3 in this bug report.

It just says PES packet size mismatch (in yellow colors) and closes
without any other error.
The same happens if i output the same stream into mpegts.
'''IMPORTANT NOTE 1'''
I noticed that without -probesize 10000000 -analyzeduration 15000000 IT
WORKS but even in this case, it is a bug, it shouldn't happen. In FFmpeg
v2.4.x that works even with these arguments in the command.
'''IMPORTANT NOTE 2'''
I also noticed that by applying +nobuffer in the -fflags it works and the
stream doesn't close, however still seems to be a bug in me.
'''IMPORTANT NOTE 3'''
+genpts doesn't affect anything.
