[FFmpeg-user] Cuvid h264_cuvid
I am using cuvid and nvenc to encode videos, i encouter videos with a vertical green line at the end. The video size is 854x480. The videos original and transcoded are on: https://live01.tvpublica.com.ar/video/ The oiriginal (mkv) and transcoded (mp4). the command line i using: ./ffmpeg -v debug -y -hwaccel cuvid -c:v h264_cuvid -deint adaptive -resize 864x480 -i ./54voONSXMrc.mkv -vcodec h264_nvenc /mnt/disk2/hls/video/out.mp4 The ffmpeg info ffmpeg version N-89432-g02ba4b91b5 Copyright (c) 2000-2017 the FFmpeg developers built with gcc 6.3.0 (Ubuntu 6.3.0-12ubuntu2) 20170406 configuration: --bindir=/root/bin --enable-nvdec --enable-cuda-sdk --enable-cuvid --enable-libnpp --extra-cflags=-I../nv_sdk --extra-ldflags=-L../nv_sdk --extra-cflags=-I/usr/local/cuda/include/ --extra-ldflags=-L/usr/local/cuda/lib64/ --enable-gpl --enable-libass --enable-libfdk-aac --enable-libx264 --enable-libx265 --enable-nvenc --enable-nonfree --enable-openssl --nvccflags='-gencode arch=compute_50,code=sm_50 -O2' --prefix=/opt/ffmpeg libavutil 56. 5.100 / 56. 5.100 libavcodec 58. 6.103 / 58. 6.103 libavformat58. 3.100 / 58. 3.100 libavdevice58. 0.100 / 58. 0.100 libavfilter 7. 7.100 / 7. 7.100 libswscale 5. 0.101 / 5. 0.101 libswresample 3. 0.101 / 3. 0.101 libpostproc55. 0.100 / 55. 0.100 Compiled with CUDA 9 the last github master branch, ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

Re: [FFmpeg-user] FFMPEG's MXF container support for DNxHR with Avid MC?
Hi Alan, What should I expect in terms of being able to record or playback DNxHR in > MXF containers using FFMPEG and the compatibility of those clips in major > NLEs? > My personal take: Don't rely on anything. If you absolutely require using Avid MC, and there are major contraints, let MC do the conversion, and if something is wrong, you need to discuss this with Avid. It's nice there are tools out there like ffmpeg, or mxflib, or bmxlib, but in the end, when a vendor decides to do their own thing (see ProRes), I think it's "wrong" to expect open source projects to address this. There's always the option of hiring a knowledgeable developer to modify the current solution to fit your requirements. > I see some support in FFMPEG source code (version 3.4) for DNxHR profiles > in libavcodec but the libavformat MXF read/write code doesn't seem to have > support for the new HR VCIDs (1270 - 1274), essence elements and other MXF > container meta data for DNxHR and yet...

In general the MXF wrapper is more a blessing than a curse because it imposes many contraints on a file when being written. But this also means not only to write correctly encoded pixel data, but also signaling the encoding parameters in the bitstream and the header correctly, which is where many tools fail. All in all, your mileage will vary here.
