From 598c46cf31bd0d786cb5907ca5f23c034cce247e Mon Sep 17 00:00:00 2001 From: Silvio Date: Tue, 5 Jul 2011 17:42:46 -0300 Subject: Adding video_ffmpeg_php transcoder This transcoder extends video_ffmpeg and uses ffmpeg-php extension to get duration, dimensions and generating thumbnails. This allows the video module to run in a restricted environment where exec() and variants are not available. --- transcoders/video_ffmpeg_php.inc | 190 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 190 insertions(+) create mode 100644 transcoders/video_ffmpeg_php.inc (limited to 'transcoders') diff --git a/transcoders/video_ffmpeg_php.inc b/transcoders/video_ffmpeg_php.inc new file mode 100644 index 0000000..478c333 --- /dev/null +++ b/transcoders/video_ffmpeg_php.inc @@ -0,0 +1,190 @@ +uri); + //get the playtime from the current transcoder + $duration = $this->get_playtime($videopath); + + $files = NULL; + for ($i = 1; $i <= $total_thumbs; $i++) { + $seek = ($duration / $total_thumbs) * $i - 1; //adding minus one to prevent seek times equaling the last second of the video + $filename = file_munge_filename("video-thumb-" . $video['fid'] .
