Register name used to load filter: fout
The file output filter can work as a null sink when its destination is
null, dropping all input packets. In this case it accepts ANY type of input pid, not just file ones.
In regular mode, the filter will dump to file incomming packets (stream type file), starting a new file for each packet having a frame_start flag set, unless operating in cat mode.
The ouput file name can use gpac templating mechanism, see gpac help.
dst (string): location of destination file - see filter help
append (boolean, default: false): open in append mode
dynext (boolean, default: false): indicate the file extension is set by filter chain, not dst
start (number, default: 0.0): set playback start offset. Negative value means percent of media dur with -1 <=> dur
speed (number, default: 1.0): set playback speed when vsync is on. If speed is negative and start is 0, start is set to -1
ext (string): set extension for graph resolution, regardless of file extension
mime (string): set mime type for graph resolution
cat (boolean, default: false): cat each file of input pid rather than creating one file per filename
ow (boolean, default: true): overwrite output if existing
mvbk (unsigned int, default: 8192): block size used when moving parts of the file around in patch mode
