  • ffmpeg produces "is_avc" = false with h264_nvenc & tee muxer

    14 août 2018, par Areeb111

    I am using ffmpeg for encoding MKV (Matroska Video files) to 2x MP4 (H264 - 720p Main@L4) & (H264 - 360p Baseline@L3.1).

    Having really strange problem when using -c:v h264_nvenc and tee muxer then the produced output file is having is_avc=false even i have checked the same input matroska file with another server running with Intel QuickSync -c:v h264_qsv with the same command then the produced output file is is_avc=true.

    The main goal that i want the is_avc=true is because the files must be played using nginx-vod-module which requires the AVC video format to be streamed.

    Steps to reproduce the problem :

    • Custom ffmpeg build with NVENC support ffmpeg version N-91182-gbdf1bbd Copyright (c) 2000-2018 the FFmpeg developers   built with gcc 4.8.5 (GCC) 20150623 (Red Hat 4.8.5-28)
    • ffprobe version 4.0.2-static https://johnvansickle.com/ffmpeg/  Copyright (c) 2007-2018 the FFmpeg developers
    • Running ffmpeg command line with NVENC and tee muxer 
      /root/ffmpeg  -y -t 00:00:50 -i "testinput.mkv" -filter_complex "[0:v]split=2[s0][s1];[s0]scale=-2:720[v0];[s1]scale=-2:360[v1]" -map "[v0]" -map "[v1]" -map 0:a -c:v h264_nvenc -b:v:0 1100k -b:v:1 600k -profile:v:0 main -profile:v:1 baseline -level:v:0 4 -level:v:1 3.1 -ac 2 -c:a aac -b:a 128k -af "aresample=async=1000:first_pts=0"  -f tee "[select=\'v:0,a\']testoutput.mp4|[select=\'v:1,a\']testoutput-360.mp4"
    • Running ffprobe for the output file to check "is_avc" : 
      ./ffprobe -v quiet -print_format json -show_format -show_streams testoutput.mp4

    • My current ffprobe output results are :

      ./ffprobe -v quiet -print_format json -show_format -show_streams testoutput.mp4

    Please anyone can help me why is the output video file is getting "is_avc=false" ?

    Is there any option to force it ?

    Thank you

  • ffmpeg ... "Impossible to convert between the formats supported by the filter"

    27 novembre 2017, par hydra3333

    Using the latest ffmpeg master built as at 2017.11.26, I’m having trouble deciphering what the error messages means and, more importantly, what to do about them.

    Changing from -vf to -filter_complex did nothing (I had to try).
    The main error message seems to be

    Impossible to convert between the formats supported by the filter

    I have tried to insert "format=" and "scale" before/between/after yadif and unsharp_opencl but to no avail.

    I wonder, could it be something to do with needing hwupload/hwdownload/hwmap or is that a red herring ?

    What am I doing wrong ?
