• convert exr filesequence with ffmpeg and x264 [closed]

  29 novembre 2012, par user1863947

  When i convert a exr sequence into quicktime mov file using ffmpeg and x264 codec it codes the video but in quicktime player and windows media player its just black ! but when i open it up with vlc i can see the image and it looks fine. When i try the same thing with a jpg sequence instead of exr it works perfect ! does anyone have an idea what that could be ?

  here is my ffmpeg code :

  ffmpeg -y -i C:/seq_v001.%04d.exr -c:v libx264 -preset slow -crf 17 C:/out.mov

  Here is the console output :

• How to directly embed an flv in actionscript so ffmpeg can convert from the compiled swf ?

  3 décembre 2012, par user1872755

  I have an flv that needs to be embedded into a swf. I am currently using the Embed tag and playing the flv with NetStream. The problem is that it does not seem to be directly embedding the flv file, as ffmpeg does not detect it. I am currently using mxmlc to compile. If published from Flash Professional the conversion works. I can't use Flash Professional because I need to use the command line. Is there a way to embed an FLV in actionscript and have ffmpeg convert it ?

• How to convert to Nellymoser 16kHz with ffmpeg ?

  21 août 2012, par Dims

  I am trying to do with the following command :

  ffmpeg -i Fairytale.mp3 -acodec nellymoser -ar 16000 -ac 1 output.flv

  and get an error

  Input #0, mp3, from 'Fairytale.mp3':
  
    Duration: 00:03:03.64, start: 0.000000, bitrate: 96 kb/s
  
      Stream #0.0: Audio: mp3, 44100 Hz, 2 channels, s16, 96 kb/s
  
  [nellymoser @ 0x7fa8c0]flv does not support that sample rate, choose from (44100, 22050, 11025).
  
  Output #0, flv, to 'output.flv':
  
      Stream #0.0: Audio: nellymoser, 16000 Hz, 1 channels, s16, 64 kb/s
  
  Stream mapping:
  
    Stream #0.0 -> #0.0
  
  Could not write header for output file #0 (incorrect codec parameters ?)

  I know definitely, that FLV+Nellymoser do supprt 16 KHz, but it should be set as separate format with zeros in rate field (Arbitrary Nellymoser is format no. 6, while 16kHz is 4).

  Is it possible to set sound resampling parameters separately from header fill-in in ffmpeg ?
