* avcodec/encode: restructure the core encoding codeJames Almer2020-06-18
| | | | | | | | | | | | | | | | This commit follows the same logic as 061a0c14bb, but for the encode API: The new public encoding API will no longer be a wrapper around the old deprecated one, and the internal API used by the encoders now consists of a single receive_packet() callback that pulls frames as required. amf encoders adapted by James Almer librav1e encoder adapted by James Almer nvidia encoders adapted by James Almer MediaFoundation encoders adapted by James Almer vaapi encoders adapted by Linjie Fu v4l2_m2m encoders adapted by Andriy Gelman Signed-off-by: James Almer <jamrial@gmail.com>

* avcodec/nvenc: use framerate if availableZachariah Brown2020-05-15
| | | | | | | | | | | | The h264_nvenc and hevc_nvenc encoders aren't respecting the framerate in the codec context. Instead it was using the timebase which in our use-case was 1/1000 so the encoder was behaving as if we wanted 1000fps. This resulted in poor encoding results due to an extremely low bitrate. Both the amf and qsv encoders already contain similar logic to first check the framerate before falling back to the timebase.

* avcodec/nvenc: refactor dts calculation logicTimo Rothenpieler2020-05-02
| | | | | | | | | | | | | The old approach used some highly complex delta computation math and output-delaying. I do not remember what the initial reasoning behind that was, but given that we can just offset the dts by the amount of bframes, it seems wholy unnecessary. This leaves open an issue with VFR content, for which some more complex logic might be needed. Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>

* nvenc: implement flush to help allow an encoder to be re-usedPhilip Langdale2020-01-08
| | | | | | It can be useful to re-use an encoder instance when doing segmented encodings, and this requires flushing the encoder at the start of each segment.

* avcodec/nvenc: only unregister input resources when absolutely neededTimo Rothenpieler2019-04-27
| | | | | | | | | | | | This reverts nvenc to old behaviour, which in some super rare edge cases performs better. The implication of this is that any potential API user who relies on nvenc cleaning up every frames device resources after it's done using them will have to change their usage pattern. That should not be a problem, since pretty much every normal usage pattern automatically implies that surfaces are reused from a common pool, since constant re-allocation is also very expensive.

* avutil/hwcontext_cuda: Define and use common CHECK_CU()Philip Langdale2018-11-14
| | | | | | | | | | | | | | | | | | We have a pattern of wrapping CUDA calls to print errors and normalise return values that is used in a couple of places. To avoid duplication and increase consistency, let's put the wrapper implementation in a shared place and use it everywhere.

| | | | | | | | This reverts commit 7d4e1f7cfb667585514bfa0a4d0fee2f717a93ed. Accidentially pushed this with a batch of other patches, and it didn't seem to break anything, so I went with it. Except it does, so reverting it it is.

* avcodec/nvenc: support dynamic aspect ratio changeMiroslav Slugeň2018-05-04
| | | | | | | | If there is input like DVB-T streams it can change aspect ratio on-the-fly, so nvenc should respect this change and change aspect ratio in encoder. Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>

* avcodec/nv{enc,dec}: use sane version checking macroTimo Rothenpieler2018-04-13
| | | | | For some odd reason, the Nvidia version macros puts the minor version in the msb, so comparing against it is impossible.
