This project is still ON DEVELOPMENT. There is no gst-gpac release yet. This project is a gstreamer element to mux .mp4 files based on gpac library (http://gpac.sf.net). The current element only mux one stream (video MPEG4 or audio AAC). Test pipeline for audio. Change input.mpg and output.mp4 as desired. -- Audio only -- $ gst-launch-0.10 gpacmux name="mpg" ! filesink location="/tmp/output.mp4" gnomevfssrc location="file:///tmp/input.mpg" ! decodebin name="d" { d. ! queue ! ffdeinterlace ! videorate ! videoscale !
