Ffmpeg vcodec h2647/5/2023 ![]() ![]() I use as follows steps to build qsv decoder environment, then I run qsv h264 decoder to decode one h264 local stream, it failed. so I want to try it performance on ubuntu 12.04. encode faster but produce larger file (use -preset veryslow for better compression). Output 2: The video was already in the required codec or no appropriate video streams were found. and found qsv h264 decoder on libavcodec. ffmpegConvert video to h264 -preset ultrafast.Is libx264 same as x264 library or something other. It gave error - 'Unknown encoder libx264'. ffmpeg -i source.mpg -vcodec h264nvenc -flags +ildct+ilme -acodec copy -f mpegts out.mpg. at 13:25 slhck - Thanks but, When I used:- ffmpeg -s 352x240 -i 352x240420.yuv -vcodec libx264 out.mp4. Output 1: The video was update and encoding was set on the file I trying transcode h264 interlaced video file with h264nvenc codec and want keep interlacing. For making video file This should be set to true in most cases unless you really want to keep multiple video streams. When checked the first video stream will be used and the other will be disabled. When force is checked, the video will be forced encoded even if it was already in the desired codec. If not it will fall back to using CPU encoding of H264. ![]() If this is set, the flow executor will determine if the Flow Runner can first hardware encoding in this order h264_nvenc (NVIDIA GPUs), h264_qsv (Intel), h264_amf (AMD), h264_vaapi.If not it will fall back to using CPU encoding of H265/HEVC. If this is set, the flow executor will determine if the Flow Runner can first hardware encoding in this order hevc_nvenc (NVIDIA GPUs), hevc_qsv (Intel), hevc_amf (AMD), hevc_vaapi.You can set the codec to these magic values and leave the parameters blank. This node will set all video streams in the file to encode using the video codec specified and the encoding parameters specified. ![]()
