• Convert wav file from WAV_FORMAT_EXTENSIBLE to WAV_FORMAT_PCM

  22 juillet 2022, par michaeljan

  I have a 16-bit 44.1kHz wav file in WAV_FORMAT_EXTENSIBLE format. What is a simple and efficient way to convert it to WAV_FORMAT_PCM on the command-line ?

  


  In case it helps, here's a sample file. It's (a part of) a file that a client sent to me, so I'm not sure how it was created. But it is understood by ffmpeg and playable by VLC.

  


  Also, I've seen this question, but it's 7 years old and the accepted answer doesn't answer the question. Also, that question asks for ffmpeg-only solutions, whereas I am open to other command-line solutions as well. (Although I do prefer ffmpeg.)

  I have a video and i want to delay it for 5 seconds and then it will start. i want to delay the video and the audio in one command.

  what i have tried is only delaying the video... and then the audio is out of sync.

  this is what i tried :

  ffmpeg -itsoffset 5 -i new1.mp4 -filter:v scale=360:-1 -c:a copy 
  
  movie-video-delayed.mp4

  i want that the movie will be paused for 5 seconds (showing first frame) and then will start.
  Thanks.

  I am trying to record a radio broadcast. However, I am not sure how to break the file every 1 hour and avoid getting the existing files overwritten. Probably add a timestamp to the filename ? Someone explain, how this part of my question is being answered in other posts ?

   -c copy "D:\Documents\ffmpeg\output.mp3"
