[gst-devel] gst-launch hangs after displaying first frame

[Kapil Agrawal]

John,

For me it work perfectly.
Please try following things

1) gst-launch v4l2src ! image/jpeg,width=320,

> ffdec_mjpeg ! ffmpegcolorspace ! ximagesink sync=false
>
To know its not because of sink dropping

2) try with videotestsrc ! jpegenc , instead of v4l2src

3) if your cam also outputs yuv/rgb try without capsfilter and decoder

4) If non of above gives any clue run with GST_DEBUG

thanks
regards
kapil
