Subject: video: add gst_video_decoder_allocate_output_frame_with_params
X-Git-Tag: 1.19.3~511^2~2580
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3bf893e12aa1161944f4fb1a1da7a1e14af92fdb;p=platform%2Fupstream%2Fgstreamer.git

video: add gst_video_decoder_allocate_output_frame_with_params

It adds a third argument to pass GstBufferPoolAcquireParams
to gst_buffer_pool_acquire_buffer.

If a user subclasses GstBufferPoolAcquireParams, this allows to
pass an updated param to the underlying buffer pool at each
gst_video_decoder_allocate_output_frame_with_params call.
