[gst-devel] Strange problem with glupload

[Roland Peffer]

Hi,

I have a strange behavior regarding the glupload plugin.

If I run:
> gst-launch -v filesrc location='/home/rpeffer/Videos/rec.mpeg' ! decodebin  ! queue max-size-buffers=0 max-size-time=0 ! glimagesink
all works fine.

But I want to use glupload to make use of the gldeinterlace plugin as well, so I tried 

st-launch -v filesrc location='/home/rpeffer/Videos/rec.mpeg' ! decodebin  ! queue max-size-buffers=0 max-size-time=0 ! glupload  ! glimagesink

what as far as I understand should do the same playback. But I get an error

gstbasesrc.c(2378): gst_base_src_loop (): /GstPipeline:pipeline0/GstFileSrc:filesrc0:
streaming task paused, reason not-negotiated (-4)
ERROR: pipeline doesn't want to preroll.


My first idea was that glupload may not like the interlaced flag. But even if I deinterlace the stream in advance the same error shows up.
The strange thing is that on other movie files it works. The one mpeg file  I just use for testing is a recording from a USB dvb-t dongle.

Anyway, the question I have is why can it be that with only glimagesink the pipeline works without problems, but with glupload before glimagesink the pipeline won't run.

Any hints are mostly welcome!

Roland
