I am doing video composition from multiple IP cameras, and have to synchronize multiple video streams. Each camera with a pipeline: rtspsrc ! decodebin ! nvvidconv ! nvvideosink, does nvvideosink sync on the clock when pushing frames to EGL stream in mailbox mode?
It should be supported.
$ gst-inspect-1.0 nvvideosink (skip...) sync : Sync on the clock flags: readable, writable Boolean. Default: true (...skip)
