From 7a3b3dc3bb2eeac4adf8b01b1b6b519bcbc48cfc Mon Sep 17 00:00:00 2001 From: Benjamin Gaignard Date: Fri, 7 Jan 2022 16:54:54 +0100 Subject: media: hevc: Remove RPS named flags Marking a picture as long-term reference is valid for DPB but not for RPS. Change flag name to match with the description in HEVC spec chapter "8.3.2 Decoding process for reference picture set". PocStCurrBefore, PocStCurrAfter, PocLtCurr lists could be built by the kernel from the DPB entries struct v4l2_hevc_dpb_entry, using the information in the rps field. This way RPS flags becomes useless and are removed. This patch breaks the staging HEVC API because it introduces a new flag, changes a field name in v4l2_hevc_dpb_entry structure and removes V4L2_HEVC_DPB_ENTRY_RPS_* flags.

The pipeline pointer is stored in the media_entity structure as part of this process, and the entity's stream count is increased, to record that the entity is streaming. When multiple video nodes are present in a pipeline, media_pipeline_start() is typically called on all of them, with the same pipeline pointer. This is taken into account in media_pipeline_start() by skipping validation for entities that are already part of the pipeline, while returning an error if an entity is part of a different pipeline. It turns out that this process is overly complicated. When media_pipeline_start() is called for the first time, it constructs the full pipeline, adding all entities and validating all the links. Subsequent calls to media_pipeline_start() are then nearly no-ops, they only increase the stream count on the pipeline and on all entities. The media_entity stream_count field is used for two purposes: checking if the entity is streaming, and detecting when a call to media_pipeline_stop() balances needs to reset the entity pipe pointer to NULL. The former can easily be replaced by a check of the pipe pointer. Simplify media_pipeline_start() by avoiding the pipeline walk on all calls but the first one, and drop the media_entity stream_count field. media_pipeline_stop() is updated accordingly.
