[Live-devel] testH264VideoToTransportStream Frame Rates

My email was a bit sketchy but your response makes sense. 
 
My AXIS cameras are set to 10 FPS and are save as *.264 video files which I then run thru the  testH264VideoToTransportStream.exe to produce the *.ts videos that I then perform KLV encoding. 
 
It may be that I'm not receiving or reading the NAL units or that the saved *.264 videos are recorded with out this info....
 
Thank you both for your input.

	What's wrong with just rewriting the timing information in the stream. I don't know H.264 internals, but in MPEG-2 terms, wouldn't scaling all the PTS and DTS values by 2.5x give the desired result?
	


Perhaps, but I'm not really sure what he 'desires'.  Scaling the timing values without dropping any frames would produce a video that plays 'slowly' - i.e., a video that used to last 10 seconds would now last 25 seconds.  But if he wants the video to to have a lower frame rate, without looking 'slow', then he'd need to decode/reencode the video. 

In any case, this is all off-topic for this mailing list.
