Description Thomas Vander Stichele 2005-12-12 17:03:36 UTC
This pipeline works in 0.8, but not in 0.10:

gst-launch-0.10 filesrc location=/tmp/overlay.png name=source ! pngdec !
alphacolor ! videomixer name=mix ! ffmpegcolorspace ! xvimagesink videotestsrc !
ffmpegcolorspace ! mix.
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
Pipeline is PREROLLED ...
ERROR: from element /pipeline0/pngdec0: Internal data stream error.
Additional debug info:
gstpngdec.c(439): gst_pngdec_task: /pipeline0/pngdec0:
stream stopped, reason not-negotiated
ERROR: pipeline doesn't want to preroll.
Setting pipeline to PAUSED ...
Setting pipeline to READY ...
Setting pipeline to NULL ...

repeat runs alternate between videotestsrc and pngdec triggering the error.

This pipeline is used to overlay images in flumotion.
