    Phoronix: RadeonSI Lands Async Video Operations For Improving FFmpeg Performance

    The RadeonSI Gallium3D driver used by all modern AMD Radeon graphics hardware has landed support in Mesa 24.3 for async VCE/UVD video operations to enhance the performance with the widely-used FFmpeg multimedia library...

    that's funny. I was just testing my radeonNI card (hd6770) and it died. it was my reference/backup/emergency/debugging card.

      Async operation is good, but not enough when working with GPU, because incoming/outcoming surfaces still needs to be cpu synced
      Vulkan Video already can sync operations with GPU fences/semaphores, but it is not related to gallium3d/vce/uvd.
      Can we hope this will be supported vaapi too?
      va:add synchornization fence for HW execution by XinfengZhang · Pull Request #810 · intel/libva
      https://github.com/intel/libva/pull/810
      do not merge! add fence in and fence out for vaEndPicture which is using to submit command buffer fence out will be signaled after HW execution, fence in is the dependencies

      This still not going to be merged and only implemented for intel...
