trying to decode a partial file

Mike Gilorma

Basically I don't put the first few encoded frames into the file, then try to decode the file. I am unable to do this. I get the following:

Error: Failed to decode video buffer

Also I'm getting this from CE_DEBUG= 3:

[Vdec2] VIDDEC2_process() failed with error (-1 ext: 0xc800)

It seems that since the encoder produces elementary streams it shouldn't matter if I miss a few frames at the beginning of the file. Also, I tried encoding all frames as I-Frames, because I was thinking that the decoder needed to start with an I-Frame, but I get the same result.

Any ideas?

Thanks!

I'm guessing the reason that I can't decode the file is due to the fact that the first thing that gets written out to the file is the VO and VOL headers and since I skip the first couple of writes, that information isn't in the file.

Is there a way to write that information out more frequently so I can stream out the elementary stream and then decode it starting at any point in the stream (give or take a few frames) ????
