Could anyone give some
comments?
I think we would rather
use playbin2 than uridecodebin for applications, so it’s better that playbin2
expose the ‘caps’ property as well.

Subject: [gst-devel] 'caps'
property of decodebin2/uridecodebin/playbin2 for 'video/x-raw-va'
‘caps’ property are defined for
decodebin2/uridecodebin as “The caps on which to stop decoding. (NULL=
default)”.
But I can’t find it for playbin2, I think we’d better
add it as well.
I met issues for creating a customized sink for libva:
‘video/x-raw-va’; my sink renders video frame as texture in Qt.
When I set playbin2 ‘video-sink’ to my customized
sink, decodebin2 doesn’t stop auto-plug (expose_pad) when it comes to
‘video/x-raw-va’ because decodebin2 doesn’t think ‘video/x-raw-va’ is a raw type.
(by the way, the auto-plug stops when playbin2 finds
it comes to a sink; however this sink is not my customized sink. because my
sink requires many app context (OpenGL etc), it is similar to clutter-gst sink)
I could fix the issue by adding ‘video/x-raw-va’ to
DEFAULT_RAW_CAPS for uridecoderbin,
But I think it should be the better solution to add
‘caps’ property for playbin2 as well.
Do you agree? Thanks.
