Class FFMpegTranscoder

java.lang.Object

org.mmbase.streams.transcoders.AbstractTranscoder

org.mmbase.streams.transcoders.CommandTranscoder

org.mmbase.streams.transcoders.FFMpegTranscoder

All Implemented Interfaces:

Serializable, Cloneable, Transcoder, PublicCloneable<Transcoder>

public class FFMpegTranscoder
extends CommandTranscoder

Transcoder that uses ffmpeg to transcode media. Possible parameters to be set in 'createcaches.xml' are: forceFormat (-f), acodec (-acodec), vcodec (-vcodec), vpre (-vpre), aq (-aq), ab (-ab), bitrate or b (-b), async (-async), framesPerSecond or r (-r), audioChannels or ac (-ac), width and height (combined to -s). Others can be added as extra parameters but will be at the end of the commands parameters. See the documentation for FFmpeg for more information.
