All,
I am trying to compile ffmpeg with x265 libs
Details of how I did it are here (without the x265 support)
https://www.apolonio.com/node/138
but I get an error when I add x265.
ERROR: x265 not found using pkg-config
If you think configure made a mistake, make sure you are using the latest
This patch just enables the path from ffmpeg to libx264,
the more encoders can be added later.

The encoders such as libx264 support different QPs offset for different MBs,
it makes possible for ROI-based encoding. It makes sense to add support
within ffmpeg to generate/accept ROI infos and pass into encoders.
Typical usage: After AVFrame is decoded, a ffmpeg filter or user's code
generates

Is this ok, or how should this be implemented instead?
Not sure I understand: How can plane get >= MA

Hello,
thanks for the comments. Most points were clear and I've changed the
code accordingly (see attached new patch).
Here are the remaining questions / points to discuss:
You can start writing it now already, because it needs to go into
doc/filters.texi.
I've added the first version in t
