Hi all，

I use dm365_h264dec_02_00_00_11_production to decode H.264 stream, now I encounter a problem :

How can I know the data in the input buffer contain a complete H.264 frame?

I configure the H.264 decoder as : ENTIREFRAME,BYTESTREAM(Not slice,NAL).

And if I input a buffer contain partial frame, whether the decoder throw a error or not?

Thanks and regards.

Archer,

Size of the frame can only be known by headers present in container formats. There is no other simple way to find that. Codec operates on elemenatry stream and does not have information about size of the frame.

In case the buffer given to decoder is smaller than a frame, the decoder will return with appropriaqte error code.

Hi Yashwant,

Thank you!

The error code returned from decoder could be a fatal error?

Regards.
