How to disable sync in parser h265parse element..weird issue

[devil coder]

Hi experts,

I am facing a weird issue, with h265parse for resolution more then
1280x720p:
but For h264parser it works but for h265parse it doesn;t work more the
1280x720p

*I am able to run with 1280x720 resolution input but not more then that .*
I am passing encoded file to h265parser and muxing it, with src, sink like
in example in tutorials(almost similar)
https://gstreamer.freedesktop.org/documentation/tutorials/basic/short-cutting-the-pipeline.html

MY Quesion:
1) How to disable the sync , such that it should not check this condition?
2) How to solve the error as this works in commandline but not in pipeline
approch.
3) WHat i am doing wrong or what i am missing.


Note :
For h264parser it works but for h265parse it doesn;t work more the 1280x720p

I wonder what issue this was trying to fix. Maybe it's worth blaming
these changes. To me, we should keep parsing random forever, we should
not hardcode how much garbage is allowed before an SPS/PPS is seen. We
could of course push warning message from time to time.

Just make sure you have a PPS/VPS/SPS within 2 MB of data (two
megabytes is really small, I'm surprised I have never met this issue
before, since I do a lot of 4K streaming).

Don't blame yourself, it's likely a bug in GStreamer. I would propose
to change this code to increase this size or remove this error
completely (I really like the second option, but have no context).

Hi all ,

I found the issue..my Nvidia SDK encoder gives a vector output but i was not
allocating memory properly ..

*ERROR*
                         vTempPacket = pEncoder->EncodeVideo();
                        buffer = gst_buffer_new_allocate(NULL,
packet.size(), NULL);
                        gst_buffer_map(buffer, &map, GST_MAP_WRITE);
                        map.size = packet.size();

                        memcpy(map.data, packet.data(), packet.size());

                        g_signal_emit_by_name(pstCallBackControl->pstGstConfig->AppSrc,
"push-buffer",
                        buffer, &ret);
                        gst_buffer_unmap(buffer, &map);
                        gst_buffer_unref(buffer);


*Fix :*

                 vTempPacket = pEncoder->EncodeVideo();

                for (std::vector<uint8_t> &packet : vTempPacket)
                {
                        buffer = gst_buffer_new_allocate(NULL, packet.size(), NULL);
                        gst_buffer_map(buffer, &map, GST_MAP_WRITE);
                        map.size = packet.size();

                        memcpy(map.data, packet.data(), packet.size());

                        g_signal_emit_by_name(pstCallBackControl->pstGstConfig->AppSrc,
"push-buffer",
                        buffer, &ret);
                        gst_buffer_unmap(buffer, &map);
                        gst_buffer_unref(buffer);
                }
