Comment (by Kozlov Sergey):

 Graph Studio Plays The File.

 I found it:
 the error is in mp4muxer or in mp4demuxer (both from GDCL).

 I will write them.
 You may also take a look at this file.
 But it is not encoder or decoder error.

 mp4muxer does not give video stream to decoder.
 There is offset overflow while reading chanks (negative offset in long
 variable).

 This may be causer by writer (mp4muxer) (wrong data written to file) or by
 reader mp4demuxer (wrong data reading place).
