I am unable to get ffmpeg to export mpegts. I've tried slightly
different compile time options, and I always get the same error:
'dts < pcr, TS is invalid'
I have been following the directions at:
http://www.ioncannon.net/programming/452/iphone-http-streaming-with-ffmpeg-and-an-open-source-segmenter/
Interesting thing to note... if you have rpmforge loaded into yum, and
then yum install ffmpeg... I can export the mpegts successfully(?),
but it is still unusable by the segmenter.
If I'm reading the following links properly... there appears to be an
issue with mpegts...

Is that correct, and is there any fix on the way?
