Trying to encode a captured frame as a Bitmap (.bmp)

[Jack D]

I get the same result doing gst-inspect-1.0 with those parameters.

VIDEO:/home/user % gst-inspect-1.0 | grep bitmap
libav:  avdec_bmp: libav BMP (Windows and OS/2 bitmap) decoder
libav:  avenc_bmp: libav BMP (Windows and OS/2 bitmap) encoder
VIDEO:/home/user % gst-inspect-1.0 avenc_bmp | grep image
      image/bmp

 The only difference I see is my search has avdec_bmp listed first.
Has anyone ever successfully saved a bitmap file from inside a program
using gst_video_convert_sample?
If I cannot come up with an elegant solution from within gstreamer, I will
be forced to either A: create a command line using gst-launch and save with
a filesink,
or B: Figure out how to take a raw image write a bitmap file myself.

Best Regards,
Jack
