* avcodec/nvenc: surface allocation reductionBen Chang2017-04-26
| | | | | | | | | | | | | | | | This patch aims to reduce the number of input/output surfaces NVENC allocates per session. Previous default sets allocated surfaces to 32 (unless there is user specified param or lookahead involved). Having large number of surfaces consumes extra video memory (esp for higher resolution encoding). The patch changes the surfaces calculation for default, B-frames, lookahead scenario respectively. The other change involves surface selection. Previously, if a session allocates x surfaces, only x-1 surfaces are used (due to combination of output delay and lock toggle logic). To prevent unused surfaces, changing surface rotation to using predefined fifo. Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>

| * pthread_frame: use better memory orders for frame progressWan-Teh Chang2016-12-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This improves commit 59c70227405c214b29971e6272f3a3ff6fcce3d0. In ff_thread_report_progress(), the fast code path can load progress[field] with the relaxed memory order, and the slow code path can store progress[field] with the release memory order. These changes are mainly intended to avoid confusion when one inspects the source code. They are unlikely to have measurable performance improvement. ff_thread_report_progress() and ff_thread_await_progress() form a pair. ff_thread_await_progress() reads progress[field] with the acquire memory order (in the fast code path). Therefore, one expects to see ff_thread_report_progress() write progress[field] with the matching release memory order. In the fast code path in ff_thread_report_progress(), the atomic load of progress[field] doesn't need the acquire memory order because the calling thread is trying to make the data it just decoded visible to the other threads, rather than trying to read the data decoded by other threads. In ff_thread_get_buffer(), initialize progress[0] and progress[1] using atomic_init(). Signed-off-by: Wan-Teh Chang <wtc@google.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>

| * binkaudio: switch to the new send/receive APIAnton Khirnov2016-12-14
| | | | | | | | | | | | It is more natural for this codec and allows to avoid awkward constructs like "consuming 0 bytes from input". Also, keep a reference to the input packet to avoid unnecessary copying.
| * vp9: split superframes in the filtering stage before actual decodingAnton Khirnov2016-12-14
| | | | | | | | | | Significantly increases the efficiency of frame threading, since individual frames in a superframe can now be decoded in parallel.
* | avcodec/crystalhd: Another attempt at using mpeg4_unpack_bframes bsfPhilip Langdale2017-04-23
| | | | | | | | | | | | | | | | | | | | I tried doing this before, but it resulted in weird behaviour with certain samples. I want to say I think I've got it sorted out now, and the new autobsf stuff makes it trivial to turn on. The native support for packed bframes is buggy and I think buggy in ways beyond what I already try to account for, so this should be a net improvements.
* | avcodec/crystalhd: Explicitly set frame pts at all timesPhilip Langdale2017-04-23
| | | | | | | | | | | | | | | | | | | | | | Previously, the pts value was initialised to AV_NOPTS_VALUE and so it was not necessary to always set it. Now, with the new-new decode API, this is no longer true. I'm not sure why I avoided setting the pts when the decoder value was also AV_NOPTS_VALUE - it clearly wouldn't have changed anything previously, but here we are. Failing to do this, means the frame pts will be some random uninitalised value.
