[gst-devel] Error playing video streams

[Görkem Çetin]

Hi

I'm new to Gstreamer, trying to find out how it works. As I try to play a
media file, I consistently get errors. Here's what I enter in the command
line:

gst-launch -v playbin uri=file:///root/test.flv

And the corresponding error is like that:

Setting pipeline to PAUSED ...
/playbin0/decodebin0/typefind.src: caps = video/x-flv
Pipeline is PREROLLING ...
/playbin0/selector_audio_src1: active-pad = "sink0"
/playbin0/selector_video_src0: active-pad = "sink0"
ERROR: from element /playbin0/vbin/videosink: Could not initialize
supporting library.
Additional debug info:
gstautovideosink.c(234): gst_auto_video_sink_detect ():
/playbin0/vbin/videosink:
Failed to find a supported video sink
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
/playbin0/decodebin0/ffdemux_flv0.audio_00: caps = NULL
/playbin0/decodebin0/ffdemux_flv0.video_00: caps = NULL
/playbin0/decodebin0/typefind.src: caps = NULL
FREEING pipeline ...

I get the same error as I test with other AVI or MPEG files - not only FLV.
My system is:

- Ubuntu 7.04
- Updated ffmpeg libraries
- Gstreamer-0.10 files (gstreamer-tools, gstreamer0.10-plugins-good,
gstreamer0.10-plugins-ugly, gstreamer0.10-alsa, gstreamer0.10-ffmpeg,
gstreamer0.10-tools, gstreamer0.10-plugins-bad,
libgstreamer-plugins-base0.10-0, libgstreamer0.10-0)

What am I doing wrong here? Is there a way to trace how and why Gstreamer
behaves ill and cannot find the codecs it finds?

Best
