Description Sebastian Dröge (slomo) 2012-01-09 15:54:32 UTC

Happens with all visualizers that are ported.

For example:
[...]

message from "player" (element): playbin-stream-changed, uri=(string)file:///home/slomo/Projects/gstreamer/head-0.11/samples/8_Channel_ID.wav;

The audio/x-raw caps arrive at xvimagesink.

Comment 2 Tim-Philipp Müller 2012-02-18 15:21:55 UTC

In the GstPlaySinkVideoConvert bin, both the videoconvert and the videoscale are bypassed and unused, instead an identity element is linked. Since we're feeding into xvimagesink by default, we get a not-negotiated.

gst-launch-0.11 playbin uri=file:///path/to/foo.flac flags="soft-volume+text+audio+video+vis" video-sink=ximagesink

works just fine, however.

Comment 3 Wim Taymans 2012-02-20 14:22:26 UTC

this fixes it for me:
