Hello. I have an nvidia 750Ti video card which is apparently VP6.
Is there a commandline program for using Nvidia's GPU encoder NVEnc, which accepts avisynth 2.5.7 input ?
I did see NVEncC 1.11
https://forum.videohelp.com/threads/370223-NVEncC-by-rigaya-NVIDIA-GPU-encoding?p=2415883&viewfull=1
however that seems as if it may have japanese scattered through instructions etc and I'm not sure how to feed it avisynth 2.5.7.
My goal is to produce mainly h264 in an mp4 container (i currently use x264.exe), but would also like to start playing with h265 as well.
(I do have avs2yuv.exe to feed into 64 bit x264, but that's it).
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays!

Are you looking for a GUI ? I think staxrip and hybrid can use them
NVEncC accepts avs scripts directly , if you use the matching version (ie. 32bit avisynth with NVEncC , or 64bit avisynth with NVEncC64) , or you can pipe to NVEncC with various methods
But it only outputs raw AVC, no container . So you'd have to use something else like mp4box as well, or one of the GUI's
eg. 1pass vbr 2000kb/s
Code:NVEncC.exe --avs -i input.avs --vbr 2000 -o output.264

My workflow is largely automated and commandline driven.
Fantastic !
Good oh. I suppose could use ffmpeg to mux the video whilst converting the audio at the same time, or use ffmpeg to convert the audio and mp4box to mux those separate streams.
Code:NVEncC.exe --avs -i input.avs --vbr 2000 -o output.264
Ah, thank you.
https://en.wikipedia.org/wiki/Nvidia_PureVideoPureVideo (eg VP6) occupies a considerable amount of a GPU's die surface and should not to be confused with Nvidia NVENC.Nvidia NVENC is the name given to Nvidia's ASIC IP block that performs video encoding. It was introduced with the Kepler-based GeForce 600 series in March 2012, as a product feature that offloads H264 video encoding from the host CPU.
Any other commandline nvenc encoders available ? -
I see https://en.wikipedia.org/wiki/Nvidia_NVENC
FFmpeg obtained support to use Nvidia NVENC in 2014. -

I would ask at zeranoe's forum to see if anyone has got it working for ffmpeg
Also look at the NVEnc help - because the switches are going to be basically the same. They might be named slightly differently due to ffmpeg syntax and formatting
Code:--cqp <int> or encode in Constant QP mode <int>:<int>:<int> Default: <I>:<P>:<B>=<20>:<23>:<25> --vbr <int> set bitrate for VBR mode (kbps) --cbr <int> set bitrate for CBR mode (kbps) Default: 7500 kbps --max-bitrate <int> set Max Bitrate (kbps) / Default: 17500 kbps
-
-h full , for the full help. -h gives the short version
I saw that someone offered to build it for you on zeranoe's forum if you PM him... take him up on the offer -
I very nearly did. Didn't though.

Why did erase all the posts ??
I was playing around with it and was going to say the quality is very poor (even worse than the NVEncC version) . But looking closer - the main reason is because the default HQ preset has zero b-frames, tiny max keyframe interval . If you set the settings similar to NVEncC , the results are closer but still some differences. I have to look a bit closer when I have time to see why there are still differences;
Very fast, but the compression is still quite poor . I was looking at the marketing slides and maxwell 2 cards are supposed to be 80% faster than maxwell 1 for NVEnc. A typical 1280x720p encode gets about 400-500 FPS on Maxwell 1 (900-1000FPS for SD) . maxwell 2 is probably decoding limited for AVC SD sources (you can get ~1000FPS-1100FPS decoding with GPU decoding)
(I built it with an autobuild script , there are 2 commonly used ones. At first I tried building it in Windows, it was a huge waste of time. Neither worked after 6+ hours each ! In linux it takes about 2 hours using the rdp version)

What details did you want specifically ?
Yes, I mean "typical" encode with I,P, 3 max b-frames for AVC . The speeds are similar (as expected) between NVEncC and the ffmpeg variant of NVEnc when using similar settings. I only tested SD and HD sources so far (no UHD), and only AVC encoding. You can run 2 simultaneous encodes if your GPU isn't at 100% (e.g. there is some bottleneck to feeding NVEnC, like resizing, filtering etc..). The FPS is almost additive with slight overhead (apparently 2 instances is the limit per GPU, but I didn't test more than 2). I didn't test HEVC encoding which is available on maxwell 2, but from another poster, it looks like HEVC encoding is as fast as AVC encoding on NVEnc (!), but has no b-frames -

An apparent lack of support for interlaced encoding may make nvenc a waste of time.
(I couldn't get it to work, the output was shuddery).
The extra time taken to deinterlace TV capture material before encoding as progressive brings the effective end-to-end throughput speed right back to the field. It unfortunately also eliminates retention of "motion fluidity" for fast sports action given by interlacing.

nvencc supports interlaced encoding

tff, bff
Does anyone know if ffmpeg has an nvidia GPU deinterlacer similar or better than yadif above ?
PS what ffmpeg switches can you use to pass to nvenc to achieve get I,P, 3 max b-frames ?
-g => max GOP size. I don't know what is "ideal" for NVEnc, but it's 250 for x264 default. It was something like 12 at default for ffmpeg NVEnc, very poor efficiency -
Thank you.
Yes; oh well I'd hoped there was a GPU deinterlacer accessible from within ffmpeg.
AVS isn't a goer for me. I tried, thinking "you beaut, GPU mpeg2 hardware decoding/deinterlacing and GPU h.264 hardware encoding", but for various reasons I am wedded to an old avisynth v2.57 which the newer ffmpeg build refuses to use directly (byo build of ffmpeg requires v2.6 or greater).
I suppose I could try avs2yuv with an AVS vs script, for PAL-SD GPU mpeg2 hardware decoding/deinterlacing feeding ffmpeg's NVEnc, sort of like
Code:".\avs2yuv.exe" "script.avs" -o - | ".\ffmpeg.exe" - --stdin y4m --thread-input --threads 8 -filter:v setdar=dar=16/9,unsharp -r 25 -c:v nvenc -preset hq -b:v 1900k -minrate 500k -maxrate 5000k -profile:v high -level 4.1 -coder 0 -bf 3 -g 50 ... etc
PS what ffmpeg switches can you use to pass to nvenc to achieve get I,P, 3 max b-frames ?
-bf 3 => max 3 b-frames
-g => max GOP size. I don't know what is "ideal" for NVEnc, but it's 250 for x264 default. It was something like 12 at default for ffmpeg NVEnc, very poor efficiency -
I also wonder if it could be possible for an ffmpeg developer to port relevant NVEncC code to "transfer" the interlaced settings and whatnot into ffmpeg for nvenc without breaking any licensing ?
For posterity, an ubuntu based fmfpeg.exe-for-windows build script is here https://github.com/rdp/ffmpeg-windows-build-helpers
Build like
Code:sudo ./cross_compile_ffmpeg.sh --gcc-cpu-count=2 --build-ffmpeg-shared=n --build-ffmpeg-static=y --disable-nonfree=n --build-libmxf=n --build-mp4box=n --build-mplayer=n --build-vlc=n --git-get-latest=y --prefer-stable=n --high-bitdepth=n --compiler-flavors=win32 --cflags="-march=sandybridge"

Yes, ffmpeg's nvenc uses -bf and -g. The quality difference is huge. That' s the first thing I noticed - why is the quality so poor compared to NVEncC (which already isn't that great compared to x264) so I looked closer at the bitstream - That's the main reason, no b-frames, short keyframe interval. In typical bitrate ranges you're already >50% worse off in terms of compression.
The ffmpeg nvenc code has provisions for interlaced encoding , and the output is flagged correctly
https://www.ffmpeg.org/doxygen/2.7/nvenc_8c_source.html
But there are big problems with it, quality wise. Something isn't implemented correctly because it works in NVEncC -
FFmpeg supports HW decoders through -hwaccel , but in reality it's not useful - at least not on windows. In my tests , the speed is the same or slower at least for dxva2. Selur had similar experience noted in this thread
http://forum.doom9.org/showthread.php?t=170793
VDPAU for NVidia is supported in FFmpeg, but only in linux. It supports deinterlacing
https://trac.ffmpeg.org/wiki/HWAccelIntro
http://http.download.nvidia.com/XFree86/vdpau/doxygen/html/index.html
If you have quicksync, qsv can be used to decode and encode. I haven't gotten around to testing the ffmpeg implementation yet. (If you have quicksync, you probably wouldn't use NVEnc, it's slower but the quality is much better at least on haswell or newer) -
Still looking to
- deinterlace using ffmpeg with an NVidia card
- and, encode interlaced with ffmpeg with an NVidia card
I receive an ffmpeg error trying to use -hwaccel with mpeg2 input (win10, latest nvidia drivers, 750Ti nvidia card).
May I enquire on your commandline ? -
You could keep an eye open at Rigaya's website for the NVEnc updates.
https://translate.googleusercontent.com/translate_c?depth=1&hl=en&prev=search&rurl=tra...aAGrEsv8UAXQDA
Then, pass your mouse over the download link just below the heading on that page for the latest version.
use { NVEnc --check-features } for what your current cpu is capable of. Then run your battery of trial and error tests encodes.
I think that these hardware encoders follow the same encoding limitations. They seem to do better on 1920x1080 pixels. Lower resolution tends to produce poor quality no matter what settings used. These encoders want clean video. Anything with compression artifacts will produce poor results once encoded by these encoders. Well, that's been my experience with QSVenc, which is from same developer, by the way. In my personal opinion, I think that Intel's Quick Sync hardware encoder produces the best quality, but then again, no one is posting actual samples (commercial movies) from NVidia and AMD devices for me to gauge from. So, I gotta believe that qs is the best so far. -
Referenced here as a "more genuine" NVEncC thread.
A fair bit of water has gone under this bridge
NVEncC can input vapoursynth .py files.
Great ! It means I can use DG's fantastic gpu enabled software filters in vapoursynth ... now I'm not sure how to also pass audio through the vapoursynth chain ...

As a side note:
NVEncC also offers lots of video post processing filters from the vpu chip.
-> check the '--vpp-.. options.
