Hi,
I am using DM368 and trying to convert h.268 to mp4 clip. Clip is playable in QT, but whiling seeking it is showing gray screen and it is jumping frames. Looks like something is wrong with mp4 header.
I am creating 4 second clip using 10 fps encoding with 5 frame I interval ( 1 I + 4 P + 1 I + ...)
I tried to do mp4dump and here are is the output. Can someone throw light what is wrong here.
I noticed h.264 codec high profile, but dont know what is different from base profile h.264 encoding to mp4 clip and High profile h.264 to mp4 clip (SPS was bigger 89 bytes)
Can someone please throw pointers.
