Hi,

The payloader requires that you tell it which payload type is assigned
to H.264

So you'd want something like this:

gst-launch-1.0 udpsrc port=5555 ! application/x-rtp, encoding-name=H264, payload=96 ! queue ! rtph264depay  ! decodebin  ! autovideosink

A bit unrelated I suppose, but I have been blocked on the subject since the
decoder only produces green frames for me (I have a Lime2 A20 to test this). If
you could share your kernel branch, and the board DT that works, I could
possibly try and find the difference and unblock this work on my side.

Of course all to be expected, the CPUs are not very fast, it is single threaded
by default (see video convert n-threads property), AND this is non-cached CMA
memory, so that is bare metal IOs, very very slow.

This is all correct, I have a super old patch here that I started for Exynos 4
DRM, but never finished it. I supposed there is likely a helper now for
DrmModeAddFb2 (with modifiers, unless that helpers only exist for the atomic
API, something on my todo). This should be good hint how to translate these
formats to DRM+Modifiers.

Hi?James,
Frame was expected to arrive @?0:02:11.042561535but it arrived on??0:02:11.050640555. Frame arrived late so sink is dropping the frame.
Have you enabled QOS. If you dont want QOS then set QOS property to false on every sink of the pipeline

Hi

I believe that I have figured out where the mistake lies in... is because I failed to fill in the filtercaps for the video in the reciever portion of the pipeline. Would just need to fill in caps=application/x-rtp to do the magic

Reciever

         gst-launch-1.0 udpsrc port=5555 caps=application/x-rtp ! rtph264depay ! decodebin  ! autovideosink

Hello Nicolas, All,

I'm dealing with Cedrus on Linux 5.15.7 with Gstreamer 1.19.3.1-git(the
latest main branch) and I've got to the point that on A13 and A20 I have
to detile the output of Sunxi video-engine, since now it's done in
software and this causes:
```
videodecoder
gstvideodecoder.c:3670:gst_video_decoder_clip_and_push_buf:<v4l2slh264dec0>
Dropping frame due to QoS.
```
using kmssink. And I get an entire frame every 5 seconds.

I've found this [1] IRC discussion where you state that kmssink support
is missing for GST_VIDEO_FORMAT_NV12_32L32. Basically what I understand
is that we need a special treatment for A13 and A20, since from >= A33
we have the support for the untiled output(still not tried, but I have
to do it with A64).

Where can I begin from to implement the kmssink support for detiling?
There is something I can imitate?
Can you or someone else point me more or less where to start working?

Sorry, I hope I got it right this time

My message being: My mistake in copying the errorneous pipeline, the sender pipeline should read instead

   "gst-launch-1.0 videotestsrc ! video/x-raw, width=640, height=480 ! queue ! vpuenc_h264 ! rtph264pay ! udpsink host=192.168.60.5 port=5555"

Is there a possibility of corrupt gstreamer installation or hardware?

Additional Information:

  1.  Sender (Embedded system on Arm on Archlinux  with Gstreamer 1.14)
  2.  Reciever (Windows x86-64 running on Windows 10 running Gstreamer 1.18)

Would different version of Gstreamer affect the system

Regards

Hi it is my mistake ... it should be width=640 instead of width=6400 in writing the post... the pipeline do not work with width=640

I am having some issues with the following gstreamer command

Sender (on embeeded system)

gst-launch-1.0 videotestsrc ! video/x-raw, width=6400, height=480 ! queue ! vpuenc_h264 ! rtph264pay ! udpsink host=192.168.60.5 port=5555


Receiver(on windows)

gst-launch-1.0 udpsrc port=5555 ! queue ! rtph264depay  ! decodebin  ! autovideosink


But I have got the following response


   Setting pipeline to PAUSED ...

    Pipeline is live and does not need PREROLL ...

    Got context from element 'autovideosink0': gst.d3d11.device.handle=context, device=(GstD3D11Device)"\(GstD3D11Device\)\ d3d11device4", adapter=(uint)0, device-id=(uint)6429, vendor-id=(uint)32902, hardware=(boolean)true, description=(string)"Intel\(R\)\ HD\ Graphics\ P530";

    Pipeline is PREROLLED ...

    Setting pipeline to PLAYING ...

    New clock: GstSystemClock

     ERROR: from element /GstPipeline:pipeline0/GstRtpH264Depay:rtph264depay0: No RTP format was negotiated.

    Additional debug info:

      ../gst-libs/gst/rtp/gstrtpbasedepayload.c(538): gst_rtp_base_depayload_handle_buffer (): /GstPipeline:pipeline0/GstRtpH264Depay:rtph264depay0:

     Input buffers need to have RTP caps set on them. This is usually achieved by setting the 'caps' property of the upstream source element (often udpsrc or appsrc), or by putting a capsfilter element before the depayloader and setting the 'caps' property on that. Also see http://cgit.freedesktop.org/gstreamer/gst-plugins-good/tree/gst/rtp/README

    Freeing pipeline ..


The complaint seem to be about the incoming stream is not in rtp format and the rtpdepayh264 should not be placed in the pipeline. This assumption is proven to be correct when i replaced the whole pipeline with a fakesink


Receiver

gst-launch-1.0 udpsrc port=5555 ! queue ! fakesink


The pipeline work. However when i observed the packets exchange in wireshark, it show the communication exchange but the protocol is in udp. Though I know that RTP could be based upon UDP protocol but have thought that Wireshark is entirely capable of showing protocol in RTP format


I have thought that the sender has already wrapped the video in rtp format before sending the package out. Like to have some ideas on what is wrong here and how to proceed

Suggest try with width=640
