Missing gstreamer plugins nice, webrtc, dtls, ...

[elgalu]

Hi, thanks a lot for this repo, it's been extremely useful!

I've customized the container considerable and for some reason I get an error after running selkies-gstreamer --addr="127.0.0.1" --port="8080"

Traceback (most recent call last):
  File "/opt/conda/bin/selkies-gstreamer", line 8, in <module>
    sys.exit(main())
  File "/opt/conda/lib/python3.10/site-packages/selkies_gstreamer/__main__.py", line 527, in main
    app = GSTWebRTCApp(stun_servers, turn_servers, enable_audio, audio_channels, curr_fps, args.encoder, curr_video_bitrate, curr_audio_bitrate)
  File "/opt/conda/lib/python3.10/site-packages/selkies_gstreamer/gstwebrtc_app.py", line 83, in __init__
    self.check_plugins()
  File "/opt/conda/lib/python3.10/site-packages/selkies_gstreamer/gstwebrtc_app.py", line 654, in check_plugins
    raise GSTWebRTCAppError('Missing gstreamer plugins:', missing)
gstwebrtc_app.GSTWebRTCAppError: ('Missing gstreamer plugins:', ['nice', 'webrtc', 'dtls', 'srtp', 'rtp', 'sctp', 'rtpmanager', 'ximagesrc', 'nvcodec'])

The plugins seem to be there, any tip on what to look at I would appreciate.

ll /opt/gstreamer/lib/x86_64-linux-gnu/libgstwebrtc-1.0.so
ll /opt/gstreamer/lib/x86_64-linux-gnu/libgstwebrtc-1.0.so.0
ll /opt/gstreamer/lib/x86_64-linux-gnu/libgstwebrtc-1.0.so.0.2005.0
etc...

@danisla any clues?

@elgalu Need all the logs. And which GStreamer did you use?

[ehfd]

@elgalu Oh, and thank you for the sponsorship. I am quite busy so the repository is in maintenance mode, thus I regret not being able to be more active but I really appreciate it. I will add more backlogs.

[elgalu]

Hi, thanks again:) here is the full output of GST_DEBUG=7 selkies-gstreamer --addr="0.0.0.0" --port="6080" https://gist.githubusercontent.com/elgalu/dc6e52d98e6effcc66c4df363bab9bbb/raw/91265f25082f94b2d2fd94a2ed66b0d5524406e5/selkies-gstreamer.sh

Now I switched from WEBRTC_ENCODER="nvh264enc" to "x264enc" so nvcodec is no longer in the list of missing plugins:

gstwebrtc_app.GSTWebRTCAppError: ('Missing gstreamer plugins:', 
['nice', 'webrtc', 'dtls', 'srtp', 'rtp', 'sctp', 'rtpmanager', 'ximagesrc'])

original posted error:

gstwebrtc_app.GSTWebRTCAppError: ('Missing gstreamer plugins:', 
['nice', 'webrtc', 'dtls', 'srtp', 'rtp', 'sctp', 'rtpmanager', 'ximagesrc', 'nvcodec'])

Just to confirm, did you install all the apt dependencies?

[elgalu]

Yes, all apt dependencies are installed. GStreamer: SELKIES_VERSION="1.3.7". Perhaps the introduction of conda messed up the plugins search paths. We'll use xpra for now. I'll re-open if I can create a reproducible public container some day. Thanks!

Ah, wait. Conda. You need to install all the dependencies in Conda.

[ehfd]

Search in conda-forge all the dependencies including Cuda and install everything.

[elgalu]

Cool! so I installed a few gstreamer gst-plugins-base gst-plugins-good gst-plugins-bad gst-plugins-ugly gst-python gst-libav webrtcvad and now the list of missing plugins is reduced to 3: 'Missing gstreamer plugins:', ['nice', 'webrtc', 'srtp']

sudo apt-get update && sudo apt-get install --no-install-recommends -y adwaita-icon-theme-full build-essential python3-pip python3-dev python3-gi python3-setuptools python3-wheel tzdata sudo udev xclip x11-utils xdotool wmctrl jq gdebi-core x11-xserver-utils xserver-xorg-core libopus0 libgdk-pixbuf2.0-0 libsrtp2-1 libxdamage1 libxml2-dev libwebrtc-audio-processing1 libcairo-gobject2 pulseaudio libpulse0 libpangocairo-1.0-0 libgirepository1.0-dev libjpeg-dev libvpx-dev zlib1g-dev x264

This was the long list of dependencies, where I believe you might want to find or build 'nice', 'webrtc', 'srtp' manually on Conda. An alternative for apt's libwebrtc-audio-processing1, libsrtp2-1, and gir1.2-nice-0.1 or libnice10 is needed. I see that there is a separate package gstreamer1.0-nice in apt.

I think: pylibsrtp provides srtp.

This is pretty much uncharted territory, and I would really appreciate if you could test things. You could ask on #gstreamer at oftc.org IRC or #_oftc_#gstreamer:matrix.org on Matrix for help from GStreamer devs.

Discussion continues on issue https://github.com/selkies-project/selkies-gstreamer/issues/63.

@elgalu Very late, but a portable distribution is now ready, based on Conda (still can't conda install -c conda-forge selkies-gstreamer but the CI builds them for you).

[elgalu]

thanks!! highly apprecianted<3
