Main use-case is to flush and free all returned buffers in a pool used by a hwaccel ctx while a new hwaccel ctx is being initialized, i.e. during seek of H.264 video and a SPS change triggers initialization of a new hwaccel ctx. For devices with memory constraints keeping all previously allocated buffers for the old hwaccel ctx around while trying to allocate new buffers for a new hwaccel ctx tend to cause to much memory usage, especially for 2160p video. This function works around this limitation by freeing all buffers that has already been returned to the pool during hwaccel uninit, before the last buffer is returned, the last buffer is most of the time being displayed and is not returned to the pool until next frame has been decoded and displayed from next hwaccel ctx. Without this the pool buffers is only freed once the last buffer is returned. Please note that I may have mixed up hwaccel and hw frames ctx above :-) This function is being called from ff_v4l2_request_uninit and v4l2_request_hwframe_ctx_free in next patch. >>> >>> Why can't av_buffer_pool_uninit() free all the buffers currently returned >>> in the pool? >>> You only seem to be calling it the function during uninitialization. >>> >> >> av_buffer_pool_uninit() frees them only after *all* the buffers have >> been returned.
