* avcodec/nvenc: add option to disable all extra SEI dataTimo Rothenpieler2021-06-06
| | | | | | | | | | | With these triggering a lot of crashes recently, an option to globally disable all of them is added as a tool to work around those crashes in case the SEI data is not needed by the user. Also re-enables s12m for hevc_nvenc, since the issue is not specifically with that, but it affects all SEI data. Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>

* avcodec/nvenc: fix lossless tuning logicTimo Rothenpieler2021-04-18
| | | | | | | | | | | | Relying on the order of the enum is bad. It clashes with the new presets having to sit at the end of the list, so that they can be properly filtered out by the options parser on builds with older SDKs. So this refactors nvenc.c to instead rely on the internal NVENC_LOSSLESS flag. For this, the preset mapping has to happen much earlier, so it's moved from nvenc_setup_encoder to nvenc_setup_device and thus runs before the device capability check.

* avcodec/nvenc: base timestamps on frameIntervalPMartin Storsjö2021-03-12
| | | | | | | | | | | | | If b-frames were enabled implicitly (if max_b_frames wasn't set by the caller at all, since a0949d0bcb0eee2f3fffcf9a4810c0295d14c0dc), we wouldn't offset dts at all, producing invalid pts/dts combinations (causing loud warnings by ffmpeg, or muxer errors if passed without an extra cleanup pass). Instead use frameIntervalP for offsetting, which should always be accurate. Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>

| | | | | | | | | | | | | | | | 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>
