 (Originally reported in ticket #403, maybe related to ticket #424).
 I will provide a link to a very long transport stream containing h264
 video and aac audio.
 ffplay, ffmpeg and mplayer -demuxer lavf play / transcode the sample with
 wrong video speed (video is too slow), works fine with mplayer -demuxer
 mpegts.
