I tryed to contact ffmpeg developers but they always said that have no problem and its working with hardware encoding but i want to use Intel HEVC software encoder plugin with ffmpegĬan someone resolve this problem? If i use sample_multi_transcode it works but with ffmpeg the final output are a green screen, i'm about 2 years with this weird problem that needs to be fixed, i heard that about frame shift when using 10 bit but i dont know how to add this to ffmpeg so i can use ffmpeg for encoding with intel software hevc encoderĬurrently i'm using Intel Core i7 7700 processor See FFmpeg Wiki: H.264 and FFmpeg Wiki: AAC for more info.I'm trying to encode with ffmpeg using the load_plugin hevc_sw that loads 2fca99749fdb49aeb121a5b63ef568f7 hevc software plugin but can't manage to get it working in 10 bit hevc encodingįfmpeg -hide_banner -v verbose -hwaccel qsv -c:v h264_qsv -i -c:v hevc_qsv -load_plugin hevc_sw -pix_fmt p010le -profile:v main10 -preset:v veryslow -gpb 0 -g 240 -refs:v 4. This allows the video to begin playing faster if it is watched via progressive download playback.

-movflags +faststart is an option for MP4 output that move some data to the beginning of the file after encoding is finished.

-vf format=yuv420p chooses YUV 4:2:0 chroma-subsampling which is recommended for H.264 compatibility.

-b:a 160k encodes the audio with a bitrate of 160k.

-c:a aac selects the audio encoder aac, which is the built-in FFmpeg AAC encoder.

Use the highest value that gives an acceptable quality. -crf 20 selects a CRF value of 20 which will result in a high quality output.Use the slowest preset that you have patience for. -preset slow selects the slow x264 encoding preset.-c:v libx264 selects the video encoder libx264, which is a H.264 encoder.Add -c:a aac: ffmpeg -i input.avi -c:v libx264 -preset slow -crf 20 -c:a aac -b:a 160k -vf format=yuv420p -movflags +faststart output.mp4
