[gst-devel] muxing and filesink

[Peter Innerhofer]

hello,

i have an issue with multiplexing and writing a stream to a file.

for example:
gst-launch v4l2src ! videoscale ! videorate !
video/x-raw-yuv,width=640,height=480,framerate=25/1 ! ffmpegcolorspace !
ffenc_mpeg4 ! avimux ! filesink location=test.avi

ok, this stream works fine. vlc can open and show codec meta data. but
now i send the stream to a udpsink and receive it.

gst-launch v4l2src ! videoscale ! videorate !
video/x-raw-yuv,width=640,height=480,framerate=25/1 ! ffmpegcolorspace !
ffenc_mpeg4 ! udpsrc host=127.0.0.1 port=5000

gst-launch udpsrc port=5000 ! video/mpeg, width=(int)640,
height=(int)480, framerate=(fraction)25/1, mpegversion=(int)4,
systemstream=(boolean)false ! avimux ! queue ! filesink location=test.avi

now the video wont play in vlc and i cant open it in video editing
programs which are not based on gstreamer, they can't find any codec details

ideas? what's wrong here, i have tried several multiplexer
(mpegtsmux,qtmux,ffmux_mp4), but its the same. shall i exit the pipeline
in an other way? (not just interrupting it)

i build a python script around this pipelines and i can start/stop the
stream with keyboard input, setting the pipelines to NULL and to
PLAYING.... sometimes the stream is playable in vlc, but mostly not.

thx
