MPEG2TS Stream Change not Handled

[Jose Santiago]

Summary of the bug:

Sometimes when I stream different MPEGTS streams to FFPlay it cannot play some of the streams. This does not happen very often. I have one set TS streams that when I stream them one after another to FFPlay it is not able to handle the second stream. If I restart FFPlay it will handle the stream until the second stream starts again. VLC does not have this issue. I will upload the streams after the ticket is created.

How to reproduce:

The files are located at ​http://162.97.176.3/ffmpeg-issue-4377-part1.ts and ​http://162.97.176.3/ffmpeg-issue-4377-part2.ts . I have also uploaded the script to stream them at ​http://162.97.176.3/ffmpeg-issue-4377.sh .

I am streaming the TS files using 'tsplay' from TSTools at ​http://code.google.com/p/tstools/ .

The following is an example of a simple script that can be used to stream them:

#!/bin/bash

trap "exit 0" INT EXIT TERM HUP PIPE QUIT ILL KILL ABRT

while true
do
   eval ./tsplay \
      ./ffmpeg-issue-4377-part1.ts \
      239.36.13.100:4900 -hd
   eval ./tsplay \
      ./ffmpeg-issue-4377-part2.ts \
      239.36.13.100:4900 -hd
done

You can also see the issue by appending the two files together and playing them using FFplay.

NOTE: Plays fine in VLC.
