[gst-devel] bayer2rgb ! ffmpegcolorspace linkage fails...

[Joshua Roys]

Hello,

Thanks for your reply, but it still doesn't work.

$ gst-launch-0.10 filesrc location=isoch.bin !
video/x-raw-bayer,width=320,height=240,blocksize=7680 ! bayer2rgb !
ffmpegcolorspace ! theoraenc ! oggmux ! filesink location=foo.ogg

(gst-launch-0.10:23670): GStreamer-CRITICAL **: gst_structure_set_value:
assertion `G_IS_VALUE (value)' failed

(gst-launch-0.10:23670): GStreamer-CRITICAL **: gst_structure_set_value:

ERROR: pipeline doesn't want to preroll.

Adding framerate between various elements causes them to not link... (I
tried between: filesrc -> bayer2rgb, bayer2rgb -> ffmpegcolorspace,
ffmpegcolorspace -> theoraenc, theoraenc -> oggmux, oggmux -> filesink)

Thanks,

Josh
