Hi IOhanness,

Thanks for the advice.

I updated and installed to GEM 0.93.3 for OSX.
Then tried to save YUV data in [pix_buffer] with the same patch, the
result was same.
This time I could get the message of saving jpeg file.

----
using YUV
Image saving support: QT
----

I also got a message of [pix_video] starting.

----
[pix_video]: backend #0='Darwin'	: darwin dv iidc analog
----

Does it help?
