muxing and filesink
Locked
 
|
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 peter ------------------------------------------------------------------------------ Beautiful is writing same markup.

In your first pipeline it should be udpsink , not udpsrc.
Another thing is that you are not properly setting up rtp packets of encoded data.
So I think your pipelines should look like this; gst-launch videotestsrc ! videoscale ! videorate ! video/x-raw-yuv,width=640,height=480,framerate=25/1 ! ffmpegcolorspace ! ffenc_mpeg4 ! rtpmp4vpay ! udpsink host=127.0.0.1 port=5000 And I could play this file using gst-launch playbin uri=file:///home/maemo/test.avi On Thu, Nov 18, 2010 at 10:02 PM, Peter Innerhofer <[hidden email]> wrote: hello, -- Regards, Sudarshan Bisht ------------------------------------------------------------------------------ Beautiful is writing same markup.

One more thing, I have used videotestsrc instead of v4l2src .first of all, thanks for your answer. but this pipeline doesn't solve my problem, vlc cant play the recorded video. (anyway the problem is not so big, and there are some workarounds) i already thought about the rtp payloader, i could even make a rtp stream with control ports, but that’s quite an overhead and i think it doesn't solve my problems ether. could it be a failure of the filesink? does the filesink add codec details, or make a header? vlc sometimes even thinks the file just has a audio track... the reason why i want it to play with vlc is, that i think it is one of the most common player on all systems and i probably want to edit it further on mfg peter ------------------------------------------------------------------------------ Beautiful is writing same markup.

Hi, You need to run gst-launch with “-e” switch on receiver side to
force EOS when you kill your pipeline, otherwise your file won’t be properly finalized. --Roope From: ext Peter Innerhofer
