thanks Ingo. you are probably right. we may need to recencode the MPEG-TS format to MP4 format for this to be valid test.
you could try remuxing it like this using ffmpeg
The reason I'm asking if you can do it, is my ME may not stutter the same way, so I can't really test for improvements .ffmpeg -i input.ts -acodec copy -vcodec copy out.mp4
But what I'll do is revert 2 changes made and post 3 videosink files (revert 1, revert 2, revert both) to test the streaming.
