• ffmpeg to convert mov to flv

  27 octobre 2014, par jeet

  I’m trying to convert a mov video to flv, but keep getting these errors below.
  There are 2 commands I used, both are below.

  ffmpeg -y -i video.mov -deinterlace -acodec copy -r 25 -qmin 3 -qmax 6 video.flv

  Second command :

  ffmpeg -y -i video.mov -deinterlace -ar 44100 -r 25 -qmin 3 -qmax 6 video.flv

  Audio resampler only works with 16 bits per sample, patch welcome.

  With a newer version of ffmpeg :

  Could not write header for output file #0 (incorrect codec parameters ?): Invalid data found when processing input

  1 more thing please :
  If I use this newer version of ffmpeg to create a video with the below command, I get a video with a very hazy display.
  It’s like a few black dots on a blank screen :

  ffmpeg -i img%d.png -i audio.wav -acodec copy output.mov

  what could be the reason for this display ?

  on ne peut pas mettre des statuts "en dur dans le code" comme ça ; il faut que tu proposes un patch qui appelle l’API autoriser, soit à travers la fonction autoriser(), soit à travers la balise #AUTORISER
