Synchronisation - GStreamer
https://gstreamer.freedesktop.org/documentation/additional/design/synchronisation.html
Synchronisation Synchronisation This document outlines the techniques used for doing synchronised playback of multiple streams. 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
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.

GStreamer should take care of synchronization for playback cases (and many others). If the video is perfectly synchronized on a desktop then you have a bug on the elements specific to your target platform (TIViddec2 and tidisplaysink2). qtdemux should already put the expected timestamps on the buffers, so it is possible that TIViddec2 isn't ...
Audio Video sync within GStreamer - Jetson TX2 - NVIDIA ...
https://forums.developer.nvidia.com/t/audio-video-sync-within-gstreamer/80548
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’.

DeepStream SDK is based on the GStreamer framework. This section describes the DeepStream GStreamer plugins and the DeepStream input, outputs, and control parameters. DeepStream SDK is supported on systems that contain an NVIDIA ® Jetson™ module or an NVIDIA dGPU adapter 1 .
GStreamer and OpenMAX IL - Plug-and-Play
https://elinux.org/images/e/e0/Gst-openmax.pdf
Instruments, NXP, and the GStreamer community. Can use multiple OpenMAX IL implementations at the same time. Transparent to applications (thanks to GStreamer’s extensibility). Usable, but not yet production ready. Can play, pause, stop, seek; keeping audio/video synchronization. Main work focused on filters; encoders, decoders. (Keep it simple)

When using a proper pipeline the sinks within it will. synchronize using the same clock. Post by Manoj89. videoappsrc->h264parser->avdec_h264->videoconvert->ximagesink. audioappsrc->aacparser->faad->audioconvert->alsasink. I get the audio and video playback without the AV sync. I am using non-live.
GStreamer / Re: [gst-devel] audio/video synchronization
https://sourceforge.net/p/gstreamer/mailman/message/13964190/
Re: [gst-devel] audio/video synchronization. Use a counter ( start value = 0, max value = 2). Update the counter each time when audio/video pads are created by decodebin. Check for this counter. When the counter reaches 2, set the pipeline to ready, and …
