  PHPVideoToolkit Error: Execute error. Output for file "C:\xampp\htdocs\phpvideo\examples\working\tmp\1336156630-4fa421d69357d\tmp_%d.jpg" 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().

  i m trying to make it work since last many hours but no luck

  Also, for this code :

  $srcFile = "test-mpeg.mpg";
  
  $ffmpegObj = new ffmpeg_movie($srcFile);

  i am gettign error that it cant file the file. i believe its something to do with permissions but i m not able to figure out

  fpoen , fwrite , file_put_contents all are working fine without any permissions problems.

  can anyone please guide me in the write direction. what do i need to do to make this phpvideotoolkit work

• Linker errors when trying to enable FFmpeg stagefright support

  6 mai 2012, par vitakot

  I want to use stagefright for HW accelerated decoding in my Android movie player
  based on FFmpeg - version 0.10.2 "Freedom". I have successfully built all the
  libraries using the build script in tools directory. However, I have many linker
  errors related to stagefright e.g. :

  undefined reference to android::OMXClient::disconnect()
  
  undefined reference to android::MediaBuffer::MediaBuffer(unsigned int)

  I thought the binaries built with stagefright support are self-contained and do
  not need any other stuff to link with. Am I doing something wrong ? Should I add
  libstagefright.so to my project ? I think it would cause many troubles with
  compatibility...

  Is it compatible with API 8 or only API 9 and above ?

  Many thanks,
  Vita

• Minimal configure flags to configure png files to mp4 and gif ?

  24 avril 2012, par Jona

  I'm trying to configure and build ffmpeg only with the most minimum libraries needed to read set of images of png type and convert those images into a movie. The movie output support I need are gif and mp4.

  I was able to get mp4 output but gif output I can't get it to work just crashes or exist without errors.

  Could not find input stream matching output stream #1.0

  There might be some extra configure flags that can be removed too...

  Here is my configure :
