Does video render support YUY2 subtype?

[pango]

I write a video source filter that send YUY2 subtype
image,but it can not connect with video render unless
insert a "avi compress" filter between them,but I
remembered that some filters also send YUY2 video can
connect with video render directly,but why my filter can
not do it?Does the video render support YUY2 subtype?

I don't know why your filter can't do it. Using intelligent connect with DV
AVI file connects in YUY2 by default here.

If I remember correctly, the video-renders insist on rgb-samples in some
situations (e.g. if the graph is paused or if it gets just started). The
switching to yuv2 will happen soon after you run the graph, but if you don't
accept any rgb-subtypes, the avi-compressor will be inserted...

Correct. If you hope to have the video renderer use a YUY2 overlay, your
filter must also support an RGB format. The graph will start in RGB format
and then switch on the fly to YUY2.
