* avcodec/snow: ensure current_picture is writable before modifying its dataJames Almer2020-06-09
| | | | | | | | current_picture was not writable here because a reference existed in at least avctx->coded_frame, and potentially elsewhere if the caller created new ones from it. Signed-off-by: James Almer <jamrial@gmail.com>
* pthread_frame: change the way delay is setAnton Khirnov2020-06-09
| | | | | | | | | It is a constant known at codec init, so set it in ff_frame_thread_init(). Also, only set it for video, since the meaning of this field is not well-defined for audio with frame threading. Fixes availability of delay in callbacks invoked from the per-thread contexts after 1f4cf92cfbd3accbae582ac63126ed5570ddfd37.
