• PHPVideoToolkit Execution error

  22 mars 2013, par Nick.h

  When I try to convert a video to flv using PHPVideoToolkit I get the following errors(output of the getErrors() method) :

  Array
  (
      [0] => PHPVideoToolkit Error : Execute error. Output for file "" was not found. Please check server write permissions and/or available codecs compiled with FFmpeg. You can check the encode decode availability by inspecting the output array from PHPVideoToolkit::getFFmpegInfo().
      [1] => PHPVideoToolkit Error : Input file "/home/nik/video1.mp4" does not exist
  )
  

  PHPVideoToolkit::getFFmpegInfo() contains flv format.

  I tested ffmpeg from command line and it works. I set permissions for both input and output directory and files to 777 but still getting the same errors.

  What's wrong ?

• ffmpeg mp4 encode 'no frame !' error

  20 avril 2012, par Lee Jacobson

  I'm using the following command to convert video to MP4 :

  /usr/bin/ffmpeg -i /home/myvideo.mp4 -sameq /home/vconverted.mp4

  Problem is I'm getting an error :

  [h264 @ 0x167335c0]no frame!
  
  Error while decoding stream 

  Is there any extra parameters I should be using to stop these errors

  Thanks !

• What are the specifications of Flex usable FLV videos ?

  26 septembre 2011, par Riduidel

  I have a server which streams FLV files to a Flex client.
  In this flex client, the video timeline advances incoherently, and no video can be seen on screen (only the sound can be heard).

  My FLV file has been generated using ffmpeg, which says (about this generated file)

  At least one output file must be specified

  Which, as far as it seems to me, is OK.

  Furthermore, the video plays nice in VLC.
