• FFMPEG - Using multiple Fiters including hardsub, denoise, watermark causes "Too many inputs" Error

  17 avril 2017, par Vahid Jamali

  I’m trying to do one command with complex filters that allow for denoising, hardsub, scaling (to 480 height) and watermark.

  I’ve gotten 3/4 filters to work in combination with each other here :

   ffmpeg -i test720.mp4 -vf hqdn3d=1.5:1.5:6:6,scale=w="if(gt(dar\,854/480)\,min(854\,iw*sar)\,2*trunc(iw*sar*oh/ih/2))":h="if(gt(dar\,854/480)\,2*trunc(ih*ow/iw/sar/2)\,min(480\,ih))"\:flags=bicubic,setsar=1\,subtitles=add.ass[out]" -c:v libx264 -crf 18 -preset veryslow -tune film -refs 8 -bf 6 -aq-mode 2  -c:a copy -f mp4 720encoded.mp4

  but when it comes to all for, it gives me a Too many inputs specified for the "movie" filter.

  Here is my command that should work but doesn’t :

   ffmpeg -i test720.mp4 -vf hqdn3d=1.5:1.5:6:6,scale=w="if(gt(dar\,854/480)\,min(854\,iw*sar)\,2*trunc(iw*sar*oh/ih/2))":h="if(gt(dar\,854/480)\,2*trunc(ih*ow/iw/sar/2)\,min(480\,ih))"\:flags=bicubic,setsar=1\,"movie=actorimage.png[wm];[in][wm]overlay=30:main_h-overlay_h-120\,subtitles=add.ass[out]" -c:v libx264 -crf 18 -preset veryslow -tune film -refs 8 -bf 6 -aq-mode 2  -c:a copy -f mp4 720encoded.mp4

  I’m sure I’m making a simply syntax error somewhere in there.

• avcodec/thread : Don't use ThreadFrame when unnecessary

  6 février 2022, par Andreas Rheinhardt

  avcodec/thread : Don't use ThreadFrame when unnecessary
  The majority of frame-threaded decoders (mainly the intra-only)
  
  need exactly one part of ThreadFrame : The AVFrame. They don't
  
  need the owners nor the progress, yet they had to use it because
  
  ff_thread_(get|release)_buffer() requires it.
  This commit changes this and makes these functions work with ordinary
  
  AVFrames ; the decoders that need the extra fields for progress
  
  use ff_thread_(get|release)_ext_buffer() which work exactly
  
  as ff_thread_(get|release)_buffer() used to do.
  This also avoids some unnecessary allocations of progress AVBuffers,
  
  namely for H.264 and HEVC film grain frames : These frames are not
  
  used for synchronization and therefore don't need a ThreadFrame.
  Also move the ThreadFrame structure as well as ff_thread_ref_frame()
  
  to threadframe.h, the header for frame-threaded decoders with
  
  inter-frame dependencies.

• how can I slow down a video (I lower pitch by a semitone) with FFMPEG ?

  8 mai 2022, par patrick

  I have an old black and white film with audio that was recorded on a phonograph and the playback speed of the audio is a semi-tone higher than it should be. How can I process this video with ffmpeg and slow down BOTH the video and audio together, bringing the audio down a half step (semi-tone) while keeping the video in sync ?

  


  I have tried filters like asetrate, setpts, atempo, etc and although I could change the pitch of the audio, the video became badly out of sync with the audio.
