Using DirectFB as video sink

[Krosh Ivanov]

Hi,
I'm trying to use DirectFB as a video sink by using the element
dfbvideosink, but it doesn't work well. The following error is showed
as soon as I run the command "gst-launch videotestsrc ! dfbvideosink":

Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element
/GstPipeline:pipeline0/GstVideoTestSrc:videotestsrc0: Could not
negotiate format
Additional debug info:
gstbasesrc.c(2787): gst_base_src_start ():
/GstPipeline:pipeline0/GstVideoTestSrc:videotestsrc0:
Check your filtered caps, if any
Setting pipeline to NULL ...
Freeing pipeline ...

The same error is showed if I try "gst-launch videotestsrc !
ffmpegcolorspace ! dfbvideosink". Is it a bug of dfbvideosink element?
I see there are other people that got this error by using the same
command, but I didn't found a solution for that yet.

Best regards,
Ivan

Hi,

I had similar issue once.... It never worked for me from the command line. There was some issue in the display and dfbvideosink caps negotiation.

But there is a example program for the same on the dfbvideosink page (google for it), i tried using that... and it works.

Basically in that, it creates the surface and attaches it to the dfbvideosink, then it works fine.

I hope it will help u.

rgds,

Ashwini
