Codecs¶
The codec name identifies a codec within GPAC. There can be several names for a given codec. The first name is used as a default file extension when dumping a raw media stream.
NOTE: This table does not include meta filters (ffmpeg, ...). Use gpac -hx codecs to list them.

Extensions and mime types¶
Extension name can be used to force output formats using ext= option of sink filters.
By default, GPAC does not rely on file extension for source processing unless -no-probe option is set, in which case ext= option may be set on source filter.
NOTE: This table does not include meta filters (ffmpeg, ...), use gpac -hx formats to list them.
