At present img2 only supports the one RAWVIDEO file type, '.y'.

The '.y' file type is special, in that it each frame consists of three files,
.y, .u, and .v. As such, img2 has to perform special processing for this type,
namely opening and closing the u & v files, and extracting planes from
the yuv420p buffer.

The .y file special processing is triggered when codec_id==CODEC_ID_RAWVIDEO.
This is fine, for the moment, because img2 only supports one RAWVIDEO file type.

Patch 2/2 adds a second RAWVIDEO filetype. I do not want the special processing
to happen for '.raw' files. So in Patch 1/1, the trigger condition is changed
to 'is_y'.
