On decoding the file this link, avctx->extradata is wrong data, there is no valid sps and pps.

Actually, mxf files does not need extradata. normally  sps and pps are stored in every IDR frame.

My decoder expects right extradata.  Yes, I can add protection to check if it's valid.

I debugged with h264dec.c, it can not find valid sps pps either.

Regards.

Yufei.
