• ffmpeg segments only the first part of my audio file

  30 juin 2012, par hammat

  I'm implementing a http live streaming server to send audio file to iOS devices.
  No problem with Apple's tools, mediafilesegmenter, my files are valid and it works fine.

  I'm trying now to segment the same file using ffmpeg. I've downloaded the last stable version which is the 0.10.2 for now.

  Here is how I try to segment my mp3 file :

  ./ffmpeg -re -i input.mp3 -f segment -segment_time 10 -segment_list outputList.m3u8 -acodec libmp3lame -map 0 output%03d.mp3

  It starts the mapping like expected but finish with only one .mp3 file.

  Did I miss something in the process ?
  Thanks in advance.

  edit

  Ok here is my latest command line :

  ffmpeg -i input.mp3 -c:a libmp3lame -b:a 128k -map 0:0 -f segment -segment_time 10 -segment_list outputlist.m3u8 -segment_format mp3 'output%03d.mp3'

  It still gives me only one file but the file is the hole song, not only one part.
  Here is the output of ffmpeg :

• Encode flv video with no audio with ffmpeg

  15 avril 2012, par David Bengoa

  I'm making an application that needs to convert videos to webm or mp4, it works great with all videos I've tried, but it fails if I use a flv file with no audio channels.

  If I pass the -an option, it works, but I can't do that because then all videos wouldn't have audio.

  Any ideas ?

• avconv on debian jessie throws error when trying to convert raw video to mp4

  20 août 2017, par Vinay Divakar

  I am trying to convert a raw video captured using a Logitech USB Cam(YUYV) to mp4 using avconv. I have tried the below to do so :

  avconv -i out.raw -c copy output.mp4
  
  avconv -i out.raw -vcodec copy -acodec copy output.mp4

  but I get an error as shown below.

  out.raw: Invalid data found when processing input

  I have checked here, but did not find any relevant examples for the above purpose.

  Edit : Added more details—

  I tried doing the below by adding the infile options as suggested :

  root@beaglebone:~/BBB_CV/boneCV# avconv -s 640x480 -framerate 30 -pix_fmt yuyv422 -f rawvideo -i out.raw -c copy output.mp4

  This got me rid of the previous error and some new ones popped up as shown below.
