[gst-devel] gst-launch and AVI file with only good plugins

[Vinay Reddy]

Thanks for the reply, Vinay.

I get the following error when I try the command you suggested:
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
ERROR: from element /pipeline0/d: Internal data stream error.
Additional debug info:
gstavidemux.c(3742): gst_avi_demux_loop (): /pipeline0/d:
streaming stopped, reason not-linked
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
FREEING pipeline ...

I already have ffmpeg and the gst-ffmpeg installed (along with the
base, good, bad and ugly plugins).

Doing a "file test.avi" gives:
test.avi: RIFF (little-endian) data, AVI, 720 x 480, ~30 fps, video:,
audio: uncompressed PCM (stereo, 48000 Hz). It's an mpeg2 file. I
tried the to play an mpeg4 file, but got the same error. I'd
appreciate any help/pointers.

Thanks,
Vinay
