"disable video filter only when using vdpau to decode H264

[3togo]

vdpau could decode more than H264 so there are two scenerios:
1) use vdpau to decode H264 movies
in this case, it is of course advisable to enable the option "disable video filter when using vdpau"
2) use vdpau to decode nor H264 movies
if u want to have "add black border on fullscreen" and "deinterlace" to be running, then u shouldn't enable the option "disable video filter when using vdpau"

However, my question is that is it possible to make an option called "disable video filter only when using vdpau to decode H264 movies"?

This has the problem that we don't know if a video is encoded in H264 until playback has started.

How about run the following command first to collect film information.
mplayer -identify xxx.avi -ao null -vo null -frames 0 2>/dev/null | grep ^ID_

Unfortunately, I know this method is ugly
