Currently EFC would be used for every RGB->NV12 conversion, even if the
target surface wasn't going to be used as encode input. Also another
issue is that there may be multiple conversions from the same source
surface before the encode operation (this is the case with B-frames
when using one source surface).
EFC is now used only if the postproc conversion is the last postproc
operation immediately before encoding.
Until it's been observed that this is the case, the shader conversion is
also applied as a fallback in case EFC could not be used.
Tested with (fixes EFC + H264 with B-frames on radeonsi):
ffmpeg -vaapi_device /dev/dri/renderD128 -f lavfi -i testsrc \
-vf hwupload,scale_vaapi=format=nv12 -c:v h264_vaapi -bf 3 \
-vframes 200 out.mp4

`Mesa <https://mesa3d.org>`_ - The 3D Graphics Library ====================================================== Source ------ This repository lives at https://gitlab.freedesktop.org/mesa/mesa. Other repositories are likely forks, and code found there is not supported. Build & install --------------- You can find more information in our documentation (`docs/install.rst <https://docs.mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://docs.mesa3d.org/meson.html>`_): .. code-block:: sh $ mkdir build $ cd build $ meson .. $ sudo ninja install Support ------- Many Mesa devs hang on IRC; if you're not sure which channel is appropriate, you should ask your question on `OFTC's #dri-devel <irc://irc.oftc.net/dri-devel>`_, someone will redirect you if necessary. Remember that not everyone is in the same timezone as you, so it might take a while before someone qualified sees your question. To figure out who you're talking to, or which nick to ping for your question, check out `Who's Who on IRC <https://dri.freedesktop.org/wiki/WhosWho/>`_. The next best option is to ask your question in an email to the mailing lists: `mesa-dev\@lists.freedesktop.org <https://lists.freedesktop.org/mailman/listinfo/mesa-dev>`_ Bug reports ----------- If you think something isn't working properly, please file a bug report (`docs/bugs.rst <https://docs.mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.rst <https://docs.mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
