Hi, i have rtsp server and i want to change rtp buffer header. For this purpose i added probe to src of
rtph265pay, but it never called. My pipeline:
( appsrc name=vsrc ! nvvidconv ! video/x-raw(memory:NVMM),format=NV12 !
omxh265enc MeasureEncoderLatency=true bitrate=20000000 control-rate=2 !
rtph265pay name=pay0 pt=96 )
Code where i attach probe:
static GstPadProbeReturn test_probe (GstPad *pad, GstPadProbeInfo *info,
gpointer user_data)
{
cout << "i'm here";
}
void mediaConfigure (GstRTSPMediaFactory* factory, GstRTSPMedia* media,
gpointer user_data)
{
GstElement *element, *rtph265pay; GstPad *pad;
element = gst_rtsp_media_get_element (media);
rtph265pay = gst_bin_get_by_name_recurse_up (GST_BIN (element), "pay0");
pad = gst_element_get_static_pad (rtph265pay, "src");
gst_pad_add_probe (pad, GST_PAD_PROBE_TYPE_BUFFER,
(GstPadProbeCallback) test_probe, NULL, NULL);
gst_object_unref (pad);
...
}
If i set "sink" instead of "src", probe works, but i need "src" to change rtp buffer header...
What is wrong here?
