Re: [Live-devel] problem by changing the framerate

However, you should - as always - make sure that each of your H.264 NAL units (coming from your "H264VideoStreamFramer" subclass) 1/ Have an accurate "fPresentationTime" (which is aligned with the 'wall clock' time that you'd get by calling "gettimeofday()", and 2/ Have accurate "fDurationInMicr

Re: [Live-devel] Achieving wraparound detection for 8-bit RTP sequence number

2009-10-27 Thread Ross Finlayson
I'm trying to investigate streaming performance when an 8-bit RTP sequence number is used. RTP's sequence numbers are 16-bit, not 8-bit. If you want to play around with a protocol that uses 8-bit sequence numbers, then you can't call it RTP (and you'll get no support from me). -- Ross Finla

2009-10-27 Thread Josephine Kakande
Hello, I'm trying to investigate streaming performance when an 8-bit RTP sequence number is used. After sequence number 255 is first reached, the sequence number does wrap round to zero as expected, but all packets thereafter are incorrectly detected as lost. These are some of the modifications
