[Live-devel] testH264VideoToTransportStream Frame Rates

[Ross Finlayson]

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.
