If the vaapi application submits SPS with pic_width_in_luma_samples not aligned to be divisible by 64, the driver overwrites it to an aligned value. But if it does so, then it should also recalculate the conformance window. Example from real life: gstreamer vah265enc built with libva < 1.21 or vaapih265enc transcoding a video of width == 854 gst-launch-1.0 uridecodebin uri=https://media.w3.org/2010/05/sintel/trailer.mp4 ! vaapih265enc ! filesink location=out.h265 The code uploads an SPS with pic_width_in_luma_samples == 864, and the driver overwrites it to 896. The conformance window provided in the SPS was 10 : 864 - 10 = 854. So after encoding the output width results in a wrong value: 896 - 10 = 886 Reviewed-by: David Rosca <david.rosca@amd.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/41997> |

`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 $ meson setup build $ ninja -C build/ $ sudo ninja -C build/ 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.
