Description
Functions and Procedures
function FfmpegVideoMimeType(const MimeType: string; const FfmpegOutput: boolean): boolean; |
Does given MIME type looks like a video file extension that can be handled (encoded or decoded) by ffmpeg.

MaximumVideoLength: Cardinal = 1 * 60 * 25; |
Maximum number of video frames to read, for TVideo.LoadFromFile.
This prevents using up all the memory by accidentaly trying to read a long movie. Remember that our current implementation is not suited for long movies, it will load very slowly and consume a lot of memory. See http://castle-engine.sourceforge.net/x3d_implementation_texturing.php notes about MovieTexture.
By default this is equal to 1 minute, for 25 frames-per-second movie. Even this can eat 2 GB for 640 x 350 resolution.
