[gst-devel] Query: ffmux_asf

[ved kpl]

Hi,

"ffdemux_asf ! ffmux_asf" is not correct, although your pipeline will work.
You need to specify the link. Your output file has only audio data,
because the demux  gets the audio data first and continues linking the
audio pads of muxer & demuxer.

Try This.
gst-launch filesrc
location=/root/Desktop/teststreams/mpeg4/mpeg4_mp3.ASF ! ffdemux_asf
name=demux demux.audio_00 ! queue ! mux.audio_0 demux.video_00 ! queue
! mux.video_0 ffmux_asf name=mux ! filesink
location=/root/Desktop/test2.asf

"gst-launch filesrc location=/root/Desktop/audioVideo/CodecH264.dat !
ffmux_asf" is wrong. You are feeding  some unknown(no caps) data (that
too not even an elementary stream) to the muxer.
