Hi Mauro, This PR takes Ezequiel's series adding H.264 decoding for hantro (https://patchwork.linuxtv.org/project/linux-media/list/?series=603). The first patch (lib/sort.c) is Acked by Andrew Morton and is intended to go in through the media subsystem since this is the first driver that uses it. This series substantially improves the H.264 API. Only H.264 slicing support still requires some more work. I double-checked that the H.264 control structures have the same layout between 32 and 64 bit architectures and do not contain any holes. The second part of this PR is core API improvements to help give more information about the HW capabilities by adding two new format flags. This second part consists of patches 1-3 and 5-8 of this series: https://patchwork.linuxtv.org/project/linux-media/list/?series=588 I dropped patch 4 until I have an Ack from Samsung, and patches 9-12 are not ready yet for merging. Most importantly, the stateful decoder specification is now merged. The final patch improves pixfmt-compressed.srt. It's still not perfect and I plan to make more changes there with references to the various codec standards, so there will be a follow-up patch, but for now this is still better than what we had. Note that the v4l2-compliance test fails with vicodec after this PR is merged. I have a patch for v4l-utils ready to fix this.
