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 Julien <div class="gmail_quote">2010/3/23 Roland Peffer <<a href="mailto:gdevel@clixxun.com">gdevel@clixxun.com</a>> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> 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!
