1425	Clips generated by ffmpeg using segment muxer are not correctly played on some videoplayers	knovz		"What I am trying to do:
I am trying to record a video stream from an IP camera (Axis 210). I am using segment to split the output in 5 second chunks and generate a playing list. 
I would like to be able to play the videos on the playlist one after the other seamlessly.
And/or be able to reproduce each one of the segment clips as an standalone movie.

What happens:
During the recording there appears to be no problem, and the clips are generated without a problem.

If I open the playlist on VLC the first clip plays smoothly. Then I have 5 seconds where VLC counter is working, but no video is played, then the second clip is played (while the time counter goes up to something like 10/5). Then 10 seconds pause, and increasing for every clip.

It also happens when playing each of the clips separatedly.
On VLC each one will have a ""no video"" time equal to the added length of all preceding files (equal to the ""start"" time), first plays ok, 5 seconds before the start of video for the second, 10 for the third... 

MPlayer OSX Extended plays the videos correctly, but the time line below the image is not correct. It indicates playing time starting on ""start"" (5 to 10 seconds on de second clip, ...) but if I try to move the video using the handle it tries to play the first 5 seconds (therefore restarting the clip).

Gnome MPlayer plays everything as I would like it (as if those were standalone movies of 5 second length).

Totem on Ubuntu plays it ok as well.

Quicktime opens and plays the first clip smoothly.
The rest of the clips, Quicktime opens them without any problem nor error message, but presenting a black screen. If I click play it plays a black screen as if everything was normal, for the duration of the clip (more or less 5 seconds in my test). Then it stops. 
On the second clip a few frames may appear at the end (the length of the clip is 5 seconds, the start time of the stream is a little before than the end).

Ticket #910 (closed as invalid) might be related.

The command:
{{{
% ffmpeg -v 9 -loglevel 99 -report \
  -i ""rtsp://192.168.1.222/mpeg4/1/media.amp"" \
  -map 0 \
  -vcodec mpeg4 \
  -t 60 -f segment \
  -segment_time 5 -segment_format mp4 \
  -segment_list testsegmentedmp4.m3u8 -segment_list_size 30 \
  testsegmentstartdelay%03d.mp4
}}}
