Encoding B-frame support with RDK

Hello,

B-frame support in Encoding is currently not supported with RDK, as I understand from previous thread.
I would like to ask if it means that when encoding with RDK only baseline profile should be used.

Thank you very much,

In RDK H264 encoder can be configured for any profile (Base/Main/High).We dont support B-frame encoding or slice based encoding but encoding can be set to any profile like high profile,main profile. Infact by default encoding of D1 streams in DVR RDK progressive demo happens in high profile and includes tools like CABAC. As you mentioned encoder advertises a profile. The decoder should be capable of decoding all features of the advertised profile but encoder may choose to use only a subset of the tools in the profile.

Hi Badri,

>No encoding can be in any profile
You probably meant here "B-frame encoding" not just any encoding I assume.
It was probably my misunderstanding of some of the issues related to MPEG standard:
The encoder can support only subset of a certain profile, while the decoder should support all features in profile, i.e. in main profile and high profile there is no support for B-frame in encoding, but it is supported in decoding with RDK. Please correct me if I'm wrong....

Thanks,

Ran

Hi Badri,

One more thing about B frame encoding: is it expected to be added in next releases ?

Thanks, Ran

B-frame encoding is not planned for the next RDK 3.5 release.

yes ofcourse, I meant if this feature is planned to be supported maybe in later releases of RDK after 3.5.
