WebThis is typically true of file-like sources that push raw byte buffers. If you don't want to explicitly set the caps, you can use gst_app_src_push_sample. This method gets the caps associated with the sample and sets them on the appsrc replacing any previously set caps (if different from sample's caps). WebGst-nvdsvideotemplate. The OSS Gst-nvdsvideotemplate plugin is a template plugin which provides a custom library hooking interface for single/batched video frame (s) processing. Custom lib implementation may have algorithms to transform or process input buffers depending upon the use case. It can support NV12 and RGBA inputs.

This will put the buffer onto a queue from which appsrc will read from in its streaming thread.
