MPEG4 decoder limitation?

Hello,

I have a question regarding the mpeg4 decoder from the ipp sample code:

When I try to decode some mpeg4 streams, the decoder does not return an error, but all decoded frames are black.
This happens only with streamswith vop_codedset tofalse in the VOPs. Is this a limitation of the decoder?

Thanks

Hi Markus,

There is no limitations, there may be some stream or codec problems. Could you send an example of the stream? In many cases it's easier to walk through decoder with the debugger. How good these streams are decoded with other (non-IPP) decoders?

Regards,
Sergey

Hello Sergey,

I have sent the stream as a private message.

Thanks,

Markus
