I still see differences in the tracer logs, but this leads me to believe that the problem is somewhere in the ffmpeg implementation. Im using a windows build of ffmpeg to encode with, and it works well on. The encoderdecoder logic is loaded into the cuda engine and runs on your nvidia cards gpus.
Improve encoding efficiency and video quality with adaptive ltr. Vc1 contains coding tools for interlaced video sequences as well as progressive encoding. It is widely characterized as an alternative to the itut and mpeg video codec standard known as h. Gpuaccelerated video processing integrated into the most popular opensource multimedia tools. Two useful presets for this are ultrafast or veryslow since either a fast encoding speed or best compression are usually the most important factors. Unfortunately more reference frames will require more time for encoding and also a tiny bit. Current versions of ffmpeg now support hardware encoding for the major gpu vendors.
Ffmpeginterop is an opensource project that aims to provide an easy way to use ffmpeg in windows 10, windows 8. At the moment, im looking at buying a 3rd party library which uses cuda to encodedecode h. Nvidia video codec sdk get started nvidia developer. Debian official packages for stablebackports, testing. By the way, after decoded one frame, passing null to the decoder to flush the decoder can help this case.

H264 encode fails on windows 10 intel developer zone.
Set reference frames to consider for motion compensation. New developer of ffmpeg can learn ffmpegs api through this software. Video encoding, decoding and transcoding are some of the. Ffmpeginterop library for windows this project is licensed from microsoft under the apache 2. Reference frames encoded with higher quality could improve image quality for the. This was the closest i could get to what the ffmpeg encoder does on a simple encode. Windows users may need to use nul instead of as the output. Install ffmpeg and run the following command to extract yuv stream. Official builds for windows, linux, and macosx are available from here. Having decided on resolutions, bitrates, and encoder software, the next most. If you find ffmpeg useful, you are welcome to contribute by donating. Windows questions find the right answers to your questions.
Control the number of reference frames used by nvenc turing gpus only. Vc1 is an evolution of the conventional dctbased video codec design also found in h. Full reference methods fr, where the whole original video signal is. Ffmpeg and libav are among the most popular opensource multimedia manipulation tools with a library of plugins that can be applied to various parts of the audio and video processing pipelines and have achieved wide adoption across the world.
