Comment (by fulinjie):

 Reproduced this issue in the latest version of ffmpeg.

 The root cause of this issue is the redundant PPS slice info attached
 behind the last frame of each segment_x.ts.

 PPS info is attached behind frame data in one PES packet, and the
 redundant info will be found while parsing.

 In h264_parser, h264_find_frame_end for last PPS info returns
 END_NOT_FOUND, and causes the following IDR frame of next segment.ts to
 return END_NOT_FOUND too. And this leads to the failure of parsing pts.

 Provide a patch to skip the redundant pps info and parse the pts info of
 following frame correctly.
