avi (MJPEG) to mpeg or something else
	2007-02-02 08:35:54
Hello, I have this video: sarah.avi: RIFF (little-endian) data, AVI, 320 x 240, 10.00 fps, video: Motion JPEG, audio: uncompressed PCM (mono, 8000 Hz) For my application I try to convert it with gstreamer into a mpeg, divx or theora video. I tried the gst-launch command from [1], but it failed with: > LC_ALL=C gst-launch-0.8 filesrc sarah.avi ! avidemux name=demux > demux.audio_00 ! decodebin ! audioconvert ! audioresample ! > autoaudiosink demux.video_00 ! queue ! decodebin ! > ffmpegcolorspace ! videoscale ! autovideosink WARNING: erroneous pipeline: no element "audioresample" Trying to run anyway. RUNNING pipeline ... ERROR: from element /pipeline0/filesrc0: No file name specified for reading. ERROR: pipeline doesn't want to play. Then I tried this: > gst-launch-0.10 filesrc file://sarah.avi ! avidemux name=demux > demux.audio_00 ! decodebin ! audioconvert ! audioresample ! > autoaudiosink demux.video_00 ! queue ! decodebin ! > ffmpegcolorspace ! videoscale ! autovideosink Setting pipeline to PAUSED ...

(gst-launch-0.10:2646): GStreamer-WARNING **: loop detected in the graph !! FREEING pipeline ... So any ideas the pipeline should look like? BTW: Could gstreamer autodetect the video format input? regards Andreas [1]http://gstreamer.freedesktop.org/data/doc/gstre amer/head/gst-plugins-good-plugins/html/gst-plugins-good-plu gins-avidemux.html ------------------------------------------------------------ ------------- Using Tomcat but need to do more?

That works. But the performance is really bad. With totem it looks really smooth. Does gst-launch not buffer the video source? regards Andreas ------------------------------------------------------------ ------------- Using Tomcat but need to do more?
