Philip Langdale	27038693bb	avcodec/nvenc: Delay identification of underlying format of cuda frames When input surfaces are cuda frames, we will not know what the actual underlying format (nv12, p010, etc) is at surface allocation time. On the other hand, we will know when the input frames are actually registered and associated with a surface. So, let's delay format discovery until registration time, which is actually how we handle other frame properties, such as dimensions. By itself, this change doesn't allow for transcoding of 10bit content from cuvid, but it reduces the problem to the hardcoding of the sw format in ffmpeg_cuvid.c Signed-off-by: Philip Langdale <philipl@overt.org> Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>	8 years ago
Philip Langdale	829db8effd	avcodec/nvenc: Remove aspect-ratio decompensation logic This dubious behaviour in nvenc was finally removed by nvidia, and as we refuse to run on anything older than 7.0, we don't need to keep it around for old versions.	8 years ago
Miroslav Slugeň	de2faec2fa	avcodec/nvenc: better surface allocation alghoritm, fix rc_lookahead 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>	8 years ago
