AW: AW: AW: Gstreamer output to a buffer then file On Jetson tegra Tx2

[Thornton, Keith]

Hi, I'm afraid I can't see how you are attempting to sync your audio with your vidour video PTS is ok incrementing every 33 ms. Does your audio start at the same time, what is the sampling rate and who is supplying the pts for your audio?

Hi Thornton,
I am finding difficulty in in syncing audio and video , i want mp4 output but not able to use mp4 muxers, because its not going in on_new_sample_from_sink function itself where i am getting mux data & writing it to in file.

Kindly help,   i Have attached the file also reference.  main.cpp
<http://gstreamer-devel.966125.n4.nabble.com/file/t378175/main.cpp>
Thanks in advance


In the function encoderCapturePlaneDqCallback i am setting PTS & in this function only i am filling data in appsrc.


                gstbuf->pts = thiz->timestamp;
		thiz->timestamp += 33333333; // ns

		gst_buffer_map (gstbuf, &map, GST_MAP_WRITE);
		memcpy(map.data, buffer->planes[0].data , buffer->planes[0].bytesused);
		gst_buffer_unmap(gstbuf, &map);

		g_signal_emit_by_name (thiz->m_appsrc_, "push-buffer", gstbuf, &ret);


Regards,
Aasim
