glupload: Add formats supported by #GstGLMemory to raw caps when generating sink pad caps
requested to merge ChaoGuo/gstreamer:fix_caps_renegotiation_failed_after_glupload_determining_the_upload_method into main
After glupload determines the upload method, if there are upstream elements that need to renegotiate caps, the negotiation may fail.
Because the src caps may only contain RGBA format, which will cause the raw caps in sink caps (transformed by src caps) also only contain RGBA format. However, the filter caps used for negotiation may be other formats.
The specific gst log is as follows:
/* filter caps provided by upstream elements */
