vvenc_reconfig support

[JamesWiblin]

Despite my best efforts i cannot get vvenc_reconfig to return anything other than VVENC_ERR_NOT_SUPPORTED. Diving into the source code, according to VVEncImpl::reconfig it seems that reconfig functionality is not implemented, is that correct?

If so, is it on the roadmap to be implemented? I was quite surpised because vvenc.h gives quite a detailed description of the function's usage but it appears not to be implemented!

vvenc_reconfig is currently only a placeholder and not implemented yet.
Do you have any particular use cases or parameter that you want to change on the fly?

[JamesWiblin]

Thank you for the reply.
The ability to change qp value or target/max bitrate when in rate control mode are the most important. Framerate would be a nice to have but not critical for our use case.

If vvenc could support bitrate reconfiguration, that would be great. Because in practical use, it would allow adjusting the bitrate according to the bandwidth situation.

Is threre any plan to do so ? @lehmann-c It is very usefull for live broadcast

[lehmann-c]

Currently there are no plans to implement such behavior as VVenC is currently not suitable for broadcast.
VVenC is neither real-time capable nor does it contains a Constant Bitrate Mode (CBR) which is needed for broadcast.
