I was thinking that MPEG2-TS container format may contain video stream encoded differently other than H.264. So is it good to take out the container part and exposing the raw stream? I faced problem when I was storing H.264 stream only using gstreamer. Video was running too fast with no timing information and VLC was unable to play that stream. how did you deal with the FID problem? coz MPEG2-TS does not provide such information. What I did was to count certain number of packets and toggle FID forcefully so that buffer is ready for reading. It looks like you are missing some packets coz of which video is bad. I faced the same problem untill i added that FID hack. I hope this will help you. Please let me know if I can help you in this.
