Help with YouTube integration

[Max Lira]

Hi, I have a problem with YouTube integration

First I followed the instructions in the documentation here https://docs.opencast.org/latest/admin/modules/youtubepublication/

I have problem with this Step:

Generate OAuth Tokens

• Start Opencast
• Follow the request URL appearing in the Opencast logs and click Accept
• The resulting website will say Received verification code. Closing...

The URL that Opencast gave me (retrieved with "systemctl status opencast -l") I copy and paste in my browser, appears a google page that let me choose the channel and if I allow the connection, I press allow and gave me the browser this error: "Impossible to connect to localhost:40696"

The URL opencast give me is (Changed some values of the keys for security reasons):

https://accounts.google.com/o/oauth2/auth?access_type=offline&approval_prompt=auto&client_id=894220757394-chasck8g4n4b4f7p9cfck4aqvjqb3ft3.apps.googleusercontent.com&redirect_uri=http://localhost:40696/Callback&response_type=code&scope=https://www.googleapis.com/auth/youtube%20https://www.googleapis.com/auth/youtube.upload%20https://www.googleapis.com/auth/youtube.readonly

What I have to do?

[Max Lira]

Updating the info, I just manually put the code in the server.

You need to add in the documentation that the localhost direction hast to be run in the server using the curl command.

Now I still have the youtube option in the add event menu grayed out, What I have missing?

In other hand, I have found in ""/etc/opencast/org.opencastproject.pm.impl.scheduling.ScheduleFeederServiceImpl.cfg"" this lines:

# Youtube delivery
org.opencastproject.publication.youtube.username=CHANGE_ME
org.opencastproject.publication.youtube.password=CHANGE_ME
org.opencastproject.publication.youtube.clientid=CHANGE_ME
org.opencastproject.publication.youtube.developerkey=CHANGE_ME
org.opencastproject.publication.youtube.category=CHANGE_ME

# Additional keywords to add to recordings
org.opencastproject.publication.youtube.keywords=CHANGE_ME
org.opencastproject.publication.youtube.private=CHANGE_ME
org.opencastproject.publication.youtube.default.playlist=CHANGE_ME

I have to fill that to make it work? With what keys I have to fill?

[Lars Kiesow]

Hi Max.
just ignore that configuration file. It shouldn't even be there and
will have no effect on your problem.

What you need to do is to create your own workflow. The default
workflow will not publish to YouTube.

Lars

[Max Lira]

Hi Lars, I made a new workflow (Attached in this message), but Still it's skipped from Opencast, the log file didn't say anything either.

I think that the publish-youtube WOH it's the issue, but there is no documentation about how to use it.

Has someone a working workflow with youtube? There is another thing to do?

[Greg Logan]

Lars, are we sure that the YouTube integration is actually working?  The pull request from John Crossman never made it into the codebase, and (afaik) the big reason he was working on that was that the API was broken, or about to be.

Afaik, the pull request from John was just an improvement. I have seen
it working after this pull request against 2.0:

https://bitbucket.org/opencast-community/matterhorn/pull-requests/407/mh-10636-add-youtube-api-v3-module/diff

This is basically the current state. I myself have, however, never
tried to publish to YouTube.

Max, your workflow is definitely missing the YouTube workflow operation
handler. Have a look at the above mentioned pull request for an example:

https://bitbucket.org/opencast-community/matterhorn/pull-requests/407/mh-10636-add-youtube-api-v3-module/diff#Letc/workflows/compose-distribute-publish.xmlT505

You have to adjust the conditions, … though.

Regards,
Lars

[Max Lira]

Thanks Lars for the resource,

In the workflow I attached, the youtube WOH is not there. I'm using the youtube WOH in ng-partial-publish.xml, after I modified that file with the resource you gave me I changed this:

<operation      id="publish-youtube"
      if="${publishToYouTube}"
      max-attempts="2"
      exception-handler-workflow="ng-partial-error"
      description="Publishing to YouTube">
      <configurations>
        <configuration key="source-tags">engage-download</configuration>
      </configurations>

    </operation>

To this:

 <operation
      id="publish-youtube"
      if="${publishToYouTube}"
      max-attempts="2"
      fail-on-error="true"
      exception-handler-workflow="error"
      description="Publish to YouTube">
      <configurations>
        <configuration key="source-flavors">presentation/trimmed</configuration>
      </configurations>
    </operation>

And  It worked like a charm.

Now I understand the context of this bug https://opencast.jira.com/browse/MH-10920

Next I have to configure the metadata in "/etc/opencast/org.opencastproject.publication.youtube.YouTubeV3PublicationServiceImpl.cfg" I found an example from the opencast fork of UCB:

Modify the values in the mentioned cfg file, for something like this:

org.opencastproject.publication.youtube.category=Education
org.opencastproject.publication.youtube.keywords=uc, berkeley, ucberkeley, webcast.berkeley, cal
org.opencastproject.publication.youtube.makeVideosPrivate=true
org.opencastproject.publication.youtube.makeVideosPrivate_prod=false
org.opencastproject.publication.youtube.defaultPlaylist=uncategorized

I hope this information will help to others to get their videos published in Youtube.

Summing-up:
To make work YouTube publishing with the default config.

1.  Follow the youtube documentation, in the part to follow the url in the browser, when the browser tries to go to localhost:4... Copy that line and run in the server command line using curl (Or follow the url if you are using the browser in the server)
2. Paste the workflow I attached in my previous answer to in "/etc/opencast/workflows"
3. Change in "ng-partial-publish.xml" The youtube part mentioned above
4. Try with a sample in the presenter stream.

In another topic for this:

Has anyone tried to merge the presenter and the presentation stream in one video to later publish in youtube?

[Lars Kiesow]

Hi Max,
it is great to hear that things now work. You now have the unique
knowledge to know what you have to do for a YouTube integration. Would
you mind extending the documentation?

You can find the current guide at:

docs/guides/admin/docs/modules/youtubepublication.md

You can also find a simple tutorial on how to create documentation pull
requests here:

Lars

Thanks for your support!

I will do that in the documentation in the next days, I'm working now documenting the Opencast + Galicaster deployment in Spanish.

Can Opencast merge the presenter and the presentation in one video side by side using FFMPEG? I saw a post from John Crossman in the FFMPEG forums talking about this and it's possible to do that https://ffmpeg.org/pipermail/ffmpeg-user/2013-June/015662.html

Have anyone tried to do a workflow that get that type of video? This would be useful for youtube publish.

[Lars Kiesow]

Hi Max,
yes you can do that. Have a look at the composite operation. It is
actually used already for the video editor preview.

[Maximiliano Lira Del Canto]

Hi, Merry Christmass to all of you in this Board.

Steven, in you installation, Did you configure the Youtube API as in the opencast documentation?, Did you enabled the youtube plugin?

The video uploads in your channel you configured earlier when you create the access code.

Hi, Max

1. Start Opencast ， 

2. cut the url from logfile ， 

3. and paste on thㄔe external browser，then youtube channel authority popup ， click Accept/Permit  tag ， 

4. get another url in address bar， then open it in the server browser using curl 

    received returning message :

root@opencast:/opt/opencast/data/opencast# curl http://localhost:48723/Callback?code=4/-gJKpENsgz2jUfHMWlxH4QRv8jop1lDjXr9kKym0Ah0#

<html>

<head><title>OAuth 2.0 Authentication Token Recieved</title></head>

<body>

Received verification code. Closing...

<script type='text/javascript'>

window.setTimeout(function() {

    window.open('', '_self', ''); window.close(); }, 1000);

if (window.opener) { window.opener.checkToken(); }

</script>

</body>

</HTML>

but still fail to get reaction on youtube channel after sending a presenter file via opencast

[Steven Hsiao]

I am not so sure

Do I need to configurate etc/org.opencastproject.publication.youtube.YouTubePublicationServiceImpl.cfg ?

or just follow the configuration etc/org.opencastproject.publication.youtube.YouTubeV3PublicationServiceImpl.cfg instead ?

[Maximiliano Lira Del Canto]

Yes, you are doing it right.

About the CFG, its not necessary to use it.

When you use the workflow:

-did you activate the youtube publish check box?

-When is working, what happens when opencast have to use the youtube module?

Go to your youtube channel (logged with the account you used it), normally, the video is uploaded as private.

Hi,Max

I did not find solution so far， but i got logfile  :

I have successfully made it by revising source flovours ，Thanks

if you want to publish the presentation stream, you have to change the line from `presenter/trimmed` to `presentation/trimmed`
