• ffmpeg - Unrecognized option lavfi_complex

  4 février 2019, par Milan

  I’m working with headphone filter command from official documentation - https://ffmpeg.org/ffmpeg-filters.html#Examples-20

  ffmpeg -i input.wav -lavfi-complex "amovie=azi_270_ele_0_DFC.wav[sr],amovie=azi_90_ele_0_DFC.wav[sl],amovie=azi_225_ele_0_DFC.wav[br],amovie=azi_135_ele_0_DFC.wav[bl],amovie=azi_0_ele_0_DFC.wav,asplit[fc][lfe],amovie=azi_35_ele_0_DFC.wav[fl],amovie=azi_325_ele_0_DFC.wav[fr],[a:0][fl][fr][fc][lfe][bl][br][sl][sr]headphone=FL|FR|FC|LFE|BL|BR|SL|SR"
  
  output.wav

  but I’m getting error

   Unrecognized option 'lavfi-complex'.

  Here is my ffmpeg version info -

• NVidia driver libraries in nvidia/cuda image

  16 février 2018, par Islam Sabyrgaliyev

  I want to run ffmpeg with cuvid hw-accelerated decoding in the container based on official nvidia/cuda image. Ffmpeg is not able to find libnvcuvid.so, although there are all required cuda libs.
  The output of ldconfig -p | grep libnv from the container :

  libnvrtc.so (libc6,x86-64) => /usr/local/cuda-9.0/targets/x86_64-linux/lib/libnvrtc.so
  
  libnvrtc-builtins.so (libc6,x86-64) => /usr/local/cuda-9.0/targets/x86_64-linux/lib/libnvrtc-builtins.so
  
  libnvidia-ptxjitcompiler.so.1 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libnvidia-ptxjitcompiler.so.1

  libnvToolsExt.so (libc6,x86-64) => /usr/local/cuda-9.0/targets/x86_64-linux/lib/libnvToolsExt.so

  Should I just copy libnvcuvid.so from the host ? Wouldn’t it break if underlying driver version changes ?

• FFmpeg : NetStream.Play.StreamNotFound on RMTP stream

  22 juillet 2014, par user2957378

  I want to take snapshots periodically of a RTMP live video stream.
  I can see the rtmp video stream using VLC. This is the rtmp url :

  rtmp://antena3fms35livefs.fplive.net/antena3fms35live-live/stream-antena3_1

  I’m using the following command to capture the snapshots, according to the official FFmpeg site here :

  ffmpeg -i rtmp://antena3fms35livefs.fplive.net/antena3fms35live-live/stream-antena3_1 -f image2 -vf fps=fps=1 out%d.png

  The command produces the following output :

  rtmp://antena3fms35livefs.fplive.net/antena3fms35live-live/stream-antena3_1: Unknown error occurred

  I’ve tried it with another rmtp streams, but I’m still getting the exact same error.

  What could be the problem ?
  Thank you !
