Comment (by hungnv):

 As you see in ticket I opened, I have been trying to use FFMpeg API to
 transcoding mpegts -> mpegts, to change video heigh, width and bitrate...
 Attached source code works, but duration of video changed and/or some
 frame was dropped. So, if I use the transcoded video and make a m3u8
 playlist, video will be sometime distorted, it's not continuous.

 I would like to transcode mpegts file to mpegts without making changes of
 its duration, and frame number.

 Can you help?
