[gst-devel] H.264 over MPEG2-TS

[Navneet Jagannathan]

You should be able to get some AVI clips here (containing H.264 video)
http://www.vsofts.com/h264/videoclips.html

I guess you could extract the video using gstreamer and encode it using
ffmpeg ("ffmpeg -f h264 -i inputFile.h264 -f mpegts outputfile.ts", I
think)

Regards,
Navneet
