[Live-devel] Playback Speed

[Mark Bondurant]

Back from Thanksgiving.

I'm playing them VLC Player. I notice that when I play them, it doesn't fill in the little length numbers on the right. I should also note that I'm using the extension ".h264", which VLC seems to recognize. I updated VLC, but it didn't help.

How are you playing the file?
   The container format you use is in charge of maintaining the timing information and the player you use or write uses the stored timestamps to gate out the frames.
Double speed is ominous though. Could it be that you have interleaved frames?
If it is AVI, then the creation code was passed the wrong numerator? or denominator?

I'm encountering a curious problem with payback speed. I'm pulling an RTSP play stream from my cameras, copying the NAL's, prepending them with the start code, as contiguous GOP units straight to disk, headers and all. And they play fine. Just at double speed. The camera is set to NTSC/H264/CIF/12 fps/Constant Bit Rate/0.125 Mbps. Any ideas what I'm doing wrong?
