I've never used Debian, but on my Ubuntu box I have installed ffmpeg from the repositories (just as it is, without any tweak or hack) and I can easily use it to transcode amr audio to (e.g.) mp3 and to transcode 3gp video to MOV encoded with h264, and to flv. On my machine, I can see ffmpeg is using libopencore-amrnb to decode amr audio files, and it is using libx264 to encode H264 video.
Now, I want to do the same on a server machine (a virtual server) where I will use PHP to call ffmpeg. I have no problem calling ffmpeg from PHP with exec(), that's not an issue.
The server has Debian Linux and it has an older version of ffmpeg installed which:
- does not have libopencore-amrnb
- does not have libx264
The system administrators told me that
- they cannot install a version of ffmpeg with support for amr codec because of some incompatibility with Debian
- libx264 is not available on Debian (as you hear it).
Is that true? Can't the mostpopular audio/video transcoding software work with some of the most common codecs on the most widely used Linux distribution??
Is there any alternative that could allow me to: 1. transcode amr audio files to mp3 2. transcode 3gp (mpeg4) video files to mov h264 video files (I.e. mov format, h264 codec)?
