[gst-devel] Strange problem with glupload

Hi Julien,
you are right! I just tried it....
feeding glupload with an pixel-aspect-ratio that is not 1/1 lets the pipeline fail.
Seems to be a bug in glupload, since linking with glimagesink without glupload in advance works fine.
Thx ,
Roland
gst-launch -v videotestsrc ! video/x-raw-yuv,format=\(fourcc\)I420,width=720,height=576,pixel-aspect-ratio=\(fraction\)64/45,framerate=\(fraction\)25/1,interlaced=true ! glupload ! glimagesink
gst-launch -v videotestsrc ! video/x-raw-yuv,format=\(fourcc\)I420,width=720,height=576,framerate=\(fraction\)25/1,interlaced=true ! glupload ! glimagesink

Hi,
I think this is due to the pixel aspect ratio that is not handled correctly by glupload.
Could you try to reproduce the pb using videotestsrc (and playing with caps (aspect ratio, framerate etcc)
Sincerely

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
