I have an special interest in the V4L2 API upgrade specifically the enable of video decode, encode, format conversion and scaling functionality features. Could everyone give me more information about it or at least where can I found more detailed information and examples.

Those this new video decode, encode, format conversion and scaling functionality V4L2 features could be used with Gstreamer pipelines ? If it is the case, how can I expose and make usage of this new features with a Gstreamer pipeline.

Thanks in advance for any help.

Best regards,
Daniel
