• Pipe input in to ffmpeg

  8 juillet 2020, par AbstractDissonance

  I am trying to use ffmpeg to decode audio data. While it works to load from a file, I would like to avoid using files because to do so, means I would have to use a temporary. Instead, I'd like to pipe in the data(which I've previously loaded) using stdin.

  



  Is this possible ?

  



  e.g.,

  



  

  1. Manually load mp3 file

  


  2. Pipe it in to the ffmpeg spawned process

  


  3. Get raw output

  


  



  (it should work with ffprobe and ffplay also)

  


• ffmpeg concat with video using image background

  16 janvier 2018, par ant-C

  Ffmpeg does not concat the media files correctly using various testing. One of the videos is a .mp4 (h264 codec) video generated previously using a .mp3 and a jpeg background. I’ve tried testing with various flags, closest I’ve gotten is below for the final output.

  My main issue is the final video with the current test, the audio is about 3 seconds delayed once the two videos are stitched together.

  Here are all the files I’m using :

  Input Files :

  • audio.mp3

  • image.jpg

  • main_video_raw.mp4

  Output Files :

  • new_image_video_raw.mp4

  • new_image_video.mp4

  • main_video.mp4

  • final_output_video.mp4

  files.txt

  file ’/tmp/new_image_video.mp4’

  file ’/tmp/main_video.mp4’
