asfmux

Muxes media into an ASF file/stream.

Pad names are either video_xx or audio_xx, where 'xx' is the stream number of the stream that goes through that pad. Stream numbers are assigned sequentially, starting from 1.

Example launch lines

(write everything in one line, without the backslash characters)

 gst-launch-1.0 videotestsrc num-buffers=250 \
 ! "video/x-raw,format=(string)I420,framerate=(fraction)25/1" ! avenc_wmv2 \
 ! asfmux name=mux ! filesink location=test.asf \
 audiotestsrc num-buffers=440 ! audioconvert \
 ! "audio/x-raw,rate=44100" ! avenc_wmav2 ! mux.

This creates an ASF file containing an WMV video stream with a test picture and WMA audio stream of a test sound.

Live streaming

asfmux and rtpasfpay are capable of generating a live asf stream. asfmux has to set its 'streamable' property to true, because in this mode it won't try to seek back to the start of the file to replace some fields that couldn't be known at the file start. In this mode, it won't also send indexes at the end of the data packets (the actual media content) the following pipelines are an example of this usage. (write everything in one line, without the backslash characters) Server (sender)

 gst-launch-1.0 -ve videotestsrc ! avenc_wmv2 ! asfmux name=mux streamable=true \
 ! rtpasfpay ! udpsink host=127.0.0.1 port=3333 \
 audiotestsrc ! avenc_wmav2 ! mux.

Client (receiver)

 gst-launch-1.0 udpsrc port=3333 ! "caps_from_rtpasfpay_at_sender" \
 ! rtpasfdepay ! decodebin name=d ! queue \
 ! videoconvert ! autovideosink \
 d. ! queue ! audioconvert ! autoaudiosink
