Without hardware acceleration, a typical command would be ffmpeg -i input.mkv -pixfmt yuv420p10le -c:v libx265 -crf 21 -x265-params profilemain10 out.mkv. ![]() How can I force h264_nvenc to accept "level=4. I am trying to encode a 10-bit H.265 video from a 8-bit H.264 source using ffmpeg with CUDA hardware acceleration. I noticed that if use libx264 instead of h264_nvenc, the encode process accepts "-level 4.1", but it take too long to complete (I want to enjoy hardware acceleration instead of CPU). When I try to run the same command above using "-level 4.2" or above, the encode process works! But it is useless for me, because I really need "-level 4.1". 264 encoder: ffmpeg -hidebanner -h encoderh264nvenc xclip -sel clip Output: Encoder h264nvenc NVIDIA NVENC H. How to use CUDA GPU hardware encoding with ffmpeg to encode h264 and h264 HEVC movies in high quality and. I read from this post that hardware encoding is currently not supported by Jetson AGX Xavier. InitializeEncoder failed: invalid param (8): Invalid Level.Įrror initializing output stream 0:0 - Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height My solution is based on FFMPEG with h264nvenc encoder. ![]() I have a Windows 10 machine with ffmpeg and Geforce 2060, so I try run below command: ffmpeg -i video.mp4 -vcodec h264_nvenc -preset slow -level 4.1 output.mp4 These videos are with level=50 and my TV plays only videos up to level=41, so I want to convert my videos using ffmpeg and hardware acceleration.
