• Converting avi to mp4 (use ffmpeg library) is very slow

  7 décembre 2012, par yAnTar

  I have task - convert any video from user to mp4 format.
  I use command

  ffmpeg -i $file -vcodec libx264 -vpre ultrafast -bt 500k -acodec libfaac -ab 56k -ac 2 -s 480x320 $outputFileMp4

  I try to change options bitrate, dimensions, but spped of converting is slow - 3 mbytes convert arround 90 seconds.

  If i convert avi to flv - no problem.

• Drupal 7 audioconverter module failed - libavcodec52 - which codec for Debian squeeze ?

  7 décembre 2012, par Meggy

  I am using the audioconverter module with the audiorecorderfield module in Drupal 7. Though it was working previously, I just recently noticed that the audioconverter module has stopped converting wav files to mp3. Here's the error in my logs ;

  MESSAGE: executing: /usr/bin/ffmpeg -i /var/aegir/platforms/drupal-7.16/sites/default/files/1354856044.wav /var/aegir/platforms/drupal-7.16/sites/default/files/1354856044.wav.mp3

  It seems similar to the fixed issue posted by tinny here http://drupal.org/node/1818308 but I have libavcodec52 installed and I'm still getting these errors.

  I can see the wav file is created by the audiorecorder module but the audioconverter module is failing on the conversion.

  Does anyone know which codec I should use in Debian 6 Squeeze ?

• FFMPEG Error AVI to FFV1

  4 décembre 2012, par Nathan

  I'm encountering the following error when transcoding using FFMPEG. From what I've been able to find, I shouldn't have to input anymore parameters or anything. I tried adding the flag "-coder 1", which got me a file, but the video was a solid block of green.

  Here's my command :

  ffmpeg -i Glueck_Newsreel.avi -vcodec ffv1 -acodec pcm_s16le mp0001.mkv

  Here's the output
