Clocks and synchronization in GStreamer
https://gstreamer.freedesktop.org/documentation/application-development/advanced/clocks.html
For this purpose, GStreamer provides a synchronization mechanism. GStreamer provides support for the following use cases: Non-live sources with access faster than playback rate. This is the case where one is reading media from a file and playing it back in a synchronized fashion. In this case, multiple streams need to be synchronized, like audio, video and subtitles.

Audio Video sync within GStreamer - Jetson TX2 - NVIDIA ...

The synchronization is handled by gstreamer frameworks. Hardware encoder should be capable of outputting 720p60 H264 stream. Should be other factors triggering off synchronization. It looks like you feed ‘video/x-raw,format=UYVY’ frames to encoder. UYVY is not supported and you should configure ‘video/x-raw (memory:NVMM),format=NV12’.
Synchronisation - GStreamer
https://gstreamer.freedesktop.org/documentation/additional/design/synchronisation.html
Synchronisation in a GstPipeline is achieved using the following 3 components: a GstClock, which is global for all elements in a GstPipeline. Timestamps on a GstBuffer. the SEGMENT event preceding the buffers. A GstClock This object provides a counter that represents the current time in nanoseconds. This value is called the absolute_time.

GStreamer and Synchronisation Made Easy. A lesser known, but particularly powerful feature of GStreamer is our ability to play media synchronised across devices with fairly good accuracy. The way things stand right now, though, achieving this requires some amount of fiddling and a reasonably thorough knowledge of how GStreamer’s synchronisation …
