gst-plugin-ndi not able to receive audio/video data

jacobsunil1987 commented 1 year ago

We have been trying to add NDI support in our webOS platform. For that we integrated gst-plugin-ndi along with libndi (NDI SDK) onto our webOS. But when we tested , we are currently facing issue in gst-plugin-ndi not receiving audio/video data.

We separately tested all examples related to libndi NDI SDK. We are able to receive audio/video data in libndi by running sender and receiver examples provided in NDI SDK. Below is the success logs of libndi after receiving video data from NDI server.

But when we try to receive data from gst-plugin-ndi , we are unable to receive the data. Below is libndi logs

Can we get any support on this issue? or we want to know the reason why no frames are received in gst-plugin-ndi.

jacobsunil1987 commented 1 year ago

One observation from logs is

metadata is received in issue case but no audio/video data after that.

We compared logs of ubuntu working case with webOS non working case.

working case - Ubuntu : ndireceiver src/receiver.rs:719:gstndi::receiver:<ndisrc0> Received metadata at timecode 0:00:00.000000000: <ndi_tally_echo on_program="true" on_preview="false"/> non working case - webOS : ndireceiver src/receiver.rs:720:gstndi::receiver:<source> Received metadata at timecode 0:00:00.000000000: <ndi_tally_echo on_program="false" on_preview="false"/>

we see that on_program= false in issue case. Any reason why this difference in metadata? Can this be the reason for not receiving audio/video data in gst-plugin-ndi?

sdroege commented 1 year ago

Can you provide a stream that shows this behaviour?

That metadata difference is going to be related, yes. However when creating the receiver, we already set that to true/false. That needs a bit of debugging directly with such a stream.

Also keep in mind that this repository is outdated. The latest version can be found at https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs/-/tree/main/net/ndi

@sdroege Thank you so much for your quick support.

We are checking on how to upload the stream file here as we have restrictions from our firewall. We will share you the file soon after clearing the restrictions. But in our observation , we find this same problem in any file streaming.

And about the metadata , we checked our issue case and we see that

Ubuntu working case : We receive metadata twice
     First time on_program="false", 
     Second time on_Program="true")

webOS non working case : metadata received only once with on_program="false"

Also we have tried to use gst-plugins-rs ndi code in our setup. We found same behaviour in that as well. We will soon provide you the logs of that.

jacobsunil1987 commented 1 year ago

@sdroege We have tried the same test run using ndi from gst-plugins-rs

Server : OBS Studio Stream file used : https://download.samplelib.com/mp4/sample-30s.mp4

Client : webOS device We have observed same behaviour in client and the streaming failed with "No frame received yet, retry".

Please report that in gitlab.freedesktop.org then, thanks. I'd also need step by step instructions for how to set up an NDI stream with OBS.

jacobsunil1987 commented 1 year ago

@sdroege Sure thanks again. I will report this issue in gitlab.freedesktop.org

we can setup NDI Server using using two options

OBS Studio as Server : https://www.youtube.com/watch?v=DTk99mHDX_I
VLC player as Server : https://player.vimeo.com/video/692271561

In both cases issue occurs. I would suggest you can try using VLC player as Server as it is easy and quick to setup. We followed the same videos to setup both VLC and OBS Studio for our NDI Streaming

jacobsunil1987 commented 1 year ago

@sdroege i would like to update you on one thing. We have been using gst-plugin-ndi over gst-plugin-rs although gst-plugin-rs has latest ndi source because in webOS , we have gstreamer 1.18 version supported. But we know that gst-plugin-rs (NDI source) depends on gstreamer 1.20. So we have been trying with gst-plugin-ndi until now.

sdroege commented 1 year ago

It does not depend on 1.20. By default it requires 1.18 but you can also compile it with 1.14 if you disable some features.

jacobsunil1987 commented 1 year ago

Once again thanks for your quick response. It really helps us know quickly on what next to be done. By the way the reason why i mentioned about the dependency of gst-plugins-rs with gstreamer 1.20, is that we got the below error while building gst-plugins-rs.

gstreamer-audio & gstreamer-pbutils were expecting v1.20

sdroege commented 1 year ago

Build inside net/ndi only instead of building everything.

Once again thanks for your quick response. It really helps us know quickly on what next to be done.

I don't expect to be able to have time to look into the actual problem anytime this week btw.

jacobsunil1987 commented 1 year ago

@sdroege The above error mentioned was got by building net/ndi alone.

And about your time, we are thankful until now for your responses to our queries. We will try to check ourself now. In any case we get any other queries , we will reach out to you later.
