Sorry, I am a little bit confuse. We can said that StageFright support MPEG2TS playback, but supporting MPEG2TS playback in RTSP is one thing, while supporting MPEG2TS playback in HLS is another one. I can see no reason that the problem in HLS can be resolved by turning on MPEG2S playback in RTSP. Do I miss anything?
