Hi Gwenole,
I thought that the intent of vaQueryImageFormats() is to return formats that
can be used for va{Create, Get, Put)Image(). Are there implementations that can
only support GetImage but not PutImage or vice versa?
Regards,
Jonathan

Subject: [Libva] [PATCH][RFC] Add vaQuery{Get,Put}ImageFormats()
Hi,
vaQueryImageFormats() returns the image formats supported by vaCreateImage().
However, some implementations may not support
vaGetImage() or vaPutImage() with a particular format. In that case, it may be
interesting to know about it beforehand, instead of having the user test the
outcome of va{Get,Put}Image() and try another format.
It should also be possible to provide a default implementation right into
va/va.c.
WDYT?
Regards,
Gwenole.
