v5: - fixed formatting - included reviwed by for patch 2 - Link to v4: https://lore.kernel.org/r/20241017-submit-v4-0-d852bc7f7fdc@chromium.org v4: - addressed feedback from Dikshita - included reviewed by for patch 1 - Link to v3: https://lore.kernel.org/r/20240814-submit-v3-0-f7d05e3e8560@chromium.org v3: - dropped reordering patch - updated cover letter v2: - cover letter - testing methodology - Signed-off-by V4L2 has support for encoding with hierarchical frames using the V4L2_CID_MPEG_VIDEO_H264_HIERARCHICAL_CODING* controls. This allows for specifing frame references needed for temporal scalability. Encoding a single stream with a single layer allows for the layer to be dropped and the stream to be decoded without artifacts. ChromeOS is planning to use this feature for the L1T2 web standard[1]. This allows video conferencing apps to encode once for a clients with different performance/bandwidth capabilities. As the application is a real time encoder only P frame support is added. The ChromeOS test framework ("tast") was used to verify that no regressions are present. This was done on SC7180 ("trogdor"). These patches were also run on SC7280, but not with as an extensive test set. Verification of the added controls was done with a bitstream analyser to make sure that reference frame management is correct.
