 With the sample from ticket #2424, it seems to be building the wrong
 index_entries list so when you seek it does not seek to a keyframe and
 long pause before video animation can begin again.

 The file plays fine for me and just a seek problem. ffplay and ffmpeg have
 problems with playback (#2424) so did not test there.

 Seems fine in WMP.

 Here's part of the index_entries list it builds. Notice pos is same for
 many and pos jump at index 66
