* avcodec/cuvid: Restore initialization of pixel format in init()Philip Langdale2016-11-23
| | | | | | | | | | | | I moved this into the handle_video_sequence callback because that's the earliest time you can make an accurate decision as to what the format should be. However, transcoding requires that the decision between using the accelerated PIX_FMT_CUDA vs a normal pix format happen at init() time. There is enough information available to make that decision and things work out with the underlying format only being discovered in the sequence callback.

* avcodec/cuvid: Add support for P010/P016 as an output surface formatPhilip Langdale2016-11-22
| | | | | | | | | | | | | | | | | The nvidia 375.xx driver introduces support for P016 output surfaces, for 10bit and 12bit HEVC content (it's also the first driver to support hardware decoding of 12bit content). The cuvid api, as far as I can tell, only declares one output format that they appear to refer to as P016 in the driver strings. Of course, 10bit content in P016 is identical to P010, and it is useful for compatibility purposes to declare the format to be P010 to work with other components that only know how to consume P010 (and to avoid triggering swscale conversions that are lossy when they shouldn't be). For simplicity, this change does not maintain the previous ability to output dithered NV12 for 10/12 bit input video - the user will need to update their driver to decode such videos.
* libavutil/hwcontext_cuda: Support P010 and P016 formatsPhilip Langdale2016-11-22
| | | | | CUVID is now capable of returning 10bit and 12bit decoded content in P010/P016. Let's support transfering those formats.
* avutil: add P016 pixel formatPhilip Langdale2016-11-22
| | | | | | | | | P016 is the 16-bit variant of NV12 (planar luma, packed chroma), using two bytes per component. It may, and in fact is most likely to, be used in situations where there are less than 16 bits of data. It is the responsibility of the writer to zero out any unused LSBs.

* avcodec/nvenc: better surface allocation alghoritm, fix rc_lookaheadMiroslav Slugeň2016-11-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | User selectable surfaces are not working correctly, if you set number of surfaces on cmdline, it will always use minimum 32 or 48 depends on selected resolution, but in nvenc it is not necessary to use so many surfaces. So from now you can define as low as 1 surface and nvenc will still work, it will ofcourse lower GPU memory usage by 95% and async_delay to zero That was the easy part, now littlebit more... Next part of this patch is to always prefer rc_lookahead to be more important for number of surfaces, than user defined surfaces value. Maximum rc_lookahead from nvidia documentation is 32, but could increase in future generations so there is no limit for this yet. Value async_depth is still accepted and prefered over rc_lookahead. There were also bug when you request more than rc_lookahead > 31, it will always set maximum 31, because surface numbers recalculation was after setting lookahead, which is now fixed. Results: If you set -rc_lookahead 32 and -bf 3 it will now use only 40 surfaces and lower GPU memory usage by 20%, also it will now increase PSNR by 0.012dB Two more comments: 1. from my internal test, i don't understand addition of 4 more surfaces when lookahead is calculated, i didn't used this and everything works as with those 4 more extra surfaces, does anybody know what is going on there? I looks like it was used for B frames which are calculated separately, because B frames maximum is 4. 2. rc_lookahead is defined default to -1, but in test condition if (ctx->rc_lookahead) which sets lookahead it will be always true, i don't know if this is intended behavior, so in default behavior is lookahead always on! This is default condition when rc_lokkahead is -1 (not defined on cmdline), whis is maybe something that is not intended: ctx->encode_config.rcParams.enableLookahead = 1; ctx->encode_config.rcParams.lookaheadDepth = 0; ctx->encode_config.rcParams.disableIadapt = 0; ctx->encode_config.rcParams.disableBadapt = 0; Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>
