[gst-devel] who will call x264enc's _setcap function?

[Chen, Weian]

Hi Mike,

What I want to pass from upstream element (camera source element) to next element (encode element) is the buffer ID of the hardware (such as camera's image buffer), which should be use in encode element's _set_caps for encoder's initialization.

I am not sure whether the information is enough.

thanks,
Weian

As I said, if you provide _specific details_, we can try to advise
about what you should do. You're refusing to provide specific details,
so we can't suggest the proper way to do things - all we can do is
guess at what you actually want to do.

For an element like x264enc (in your example) it would be totally
inappropriate to add codec_data to the upstream element's srcpad caps.
So, either your example is completely different from what you actually
want to do, or you need to explain _exactly_ what you want to do so
that we can tell you what the proper approach is.

Mike
