Hi. Thanks in advance.
I want to record a video from an rtsp video camera and at the same time process the video frame obtained from appsink throught new-sample signal. Then, in a separate application I read the video and show the information related to the frames.
I have this pipeline:
rtspsrc location=rtsp://
10.0.0.1:554/video.sdp latency=100 ! rtph264depay ! tee name=t
! queue ! vaapidecodebin ! vaapipostproc format=rgba ! appsink name=appsink t.
! queue ! h264parse ! mp4mux ! filesink sync=false name=filer location=/home/VideoDB/2017-09-04_16:33:46.mp4
GstFlowReturn GstVideoSourcePrivate::newSample(GstAppSink* sink, gpointer user_data)
{
....
GstSample* sinkSample = gst_app_sink_pull_sample(GST_APP_SINK(sink));
if (sinkSample) {
GstBuffer* buffer = gst_sample_get_buffer(sinkSample);
// I need this position to be the same as the recorded video
GstClockTime pos;
gst_element_query_position(self->pipeline(), GST_FORMAT_TIME, &pos);
...
}
...
}
