Sync audio and video when playing mp4 file with …

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 copying those to its …

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’.

Clocks and synchronization in GStreamer

GStreamer uses a GstClock object, buffer timestamps and a SEGMENT event to synchronize streams in a pipeline as we will see in the next sections. Clock running-time In a typical computer, there are many sources that can be used as a time source, e.g., the system time, soundcards, CPU performance counters, etc.

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 …

Audio/Video over RTP With GStreamer (Linux)

https://developer.toradex.com/knowledge-base/audio-video-over-rtp-linux

GStreamer provides an h.264 encoding element by software named x264enc. Use this plugin if your SoM does not support H.264 encoding by hardware or if you want to use the same pipeline on different modules. Note that the video performance will be lower compared with the plugins with encoding accelerated by hardware.
