• FFMPEG [h264_nvenc @ 0x56151389fe00] Cannot get the preset configuration : invalid version (15)

  22 avril 2018, par Netheme

  i have issue with ffmpeg as usual :D. I have FFMPEG compiled (version N-90807-g00099ef0d0) with NVIDIA support (latest CUDA and latest NV Headers) :

  I got this error :

  I have same version of FFMPEG compiled by the same way on another testing machine and there it is working. I tried to recompile/reinstall ffmpeg with the latest version, but result is the same.

  Does someone know what could be wrong on my instance ?
  Thanks.

• FFMPEG : Need to mix dow multiple audio stream to single stereo

  17 avril 2018, par Serge Dumoulin

  I have an input file with 2 stereo stream of audio.
  I am trying to create an output wav file with the audio mixdown :
  first stereo stream mixdown to left channel of a single stereo stream
  Second stereo stream mixdown to right channel of the same stereo stream.
  So output file have only one stereo stream.
  I have tried different things but its not clear how to manage streams and channels inside them. Found no example on how to do this.

  I’ve tried playing with -filter_complex , amix, and amerge filters, as well as the -map parameter, but I can’t seem to find the right combination of values.

  Here was my input file looks like :
