I´ve seen a little problem after installing HBBTV openpli7.0rc with uno4kse

 

the HBBTV works fine, If installed the webkithbbtv 1.1-20170105.r0.0)

 

After zapping to a hbbtv channel and receiving the video and audio there is a little delay after pressing a key on the remote control. I think the reason maybe that the hbbtv plugin makes some actions on the channel with hbbtv and  blocks  the enigma process therefor.

 

Is that possible?

 

Do you think this delay can be optimize in future are is there noch chance?

Unfortunately, HbbTV browsers are supplied by the manufacturer (in this case VU+) as a binary package, we don't have any control over it, it either works, or it doesn't.

[anudanan]

Today I´ve made some additional tests with HBBTV on my unok4se. I told you I see a delay in the reaction of remote control keys after switching to an HBBTV channel. 

The reason is that the hbbtc plugin gets an callback from channelswitching if hbbtv is on that channel, The plugin would like to detect the hbbt items to build the menu entries.

But this action blocks enigma

 

Now I have made some code changes to the /usr/lib/enigma2/python/Plugins/Extensions/WebkitHbbTV/plugin,py. My idea was that detecting the hbbt items for build to menu entries is only need if a user would like to use the hbbtv. After the code changes there is no delay by using the box in normal mode. But if I press the blue key for the menu hbbt or long the red key the hbbty plugin now scans the channel for the hbbts items and build the menu entries. That works much better and for me know ok.

 

Here are the lines which I have changed. I´ve comment out the get:autostart:application() that produces the delay by every channel switch

	def _cb_ait_detected(self):
		vbcfg.g_channel_info = None
		self._applicationList = None
#		self._app_info = self.get_autostart_application()
		vbcfg.DEBUG("detected AIT")

and 

 

here the line 2,3,4 are new

1	def menu_hbbtv_applications(self):
2		vbcfg.g_channel_info = None
3		self._applicationList = None
4		self._app_info = self.get_autostart_application()
5               applications = []
6		if self._applicationList is not None:
7			for x in self._applicationList:
8				applications.append((x["name"], x))
9		else:
10			applications.append((_("No detected HbbTV applications."), None))
11		self.session.openWithCallback(self.start_application_selected, ChoiceBox, title=_("Please choose an HbbTV application."), list=applications)

if you like you can merge this changes to you git

One more optimization. Now the delay is only there, if you enter the first time HBBTV on a channel

 

Only the lines 2,3 are new in difference to the original one. Thar work better than my changes in the last post

1	def menu_hbbtv_applications(self):
2		if self._applicationList is None:
3			self._app_info = self.get_autostart_application()
4		applications = []
5		if self._applicationList is not None:
6			for x in self._applicationList:
7				applications.append((x["name"], x))
8		else:
9			applications.append((_("No detected HbbTV applications."), None))
10		self.session.openWithCallback(self.start_application_selected, ChoiceBox, title=_("Please choose an HbbTV application."), list=applications)

This isn't in our git, it is in the BSP repo which is maintained by VU+, we don't have write access to it.

[anudanan]

Thanks for that info.

 

I will report that in the VTI forum. Hopefully they can give that idea to VU

 

I will change these line by hand for my installation here and do it again if I will update in future

Better create a pull request in github.

[WanWizard]

I wonder if that is possible. afaik the hbbtv stuff is pulled in in binary from VU's ftp server.

[anudanan]

Where exactly? I‘m not so familiar with the different repros there

[anudanan]

In the WebKit Extension Plugin directory there are files in Python source code

[WanWizard]

On the box, yes.

 

According to the recipe, the data comes from a non-public VU+ git repo: https://github.com/O...-gtk_git.bb#L22

[athoik]

I think he refers to this: https://github.com/O...-webkithbbtv.bb

[anudanan]

Is it possible to make a pull request on a non public repro?

[WanWizard]

I think he refers to this: https://github.com/O...-webkithbbtv.bb

 

Ah, ok. That is a tarball which is pulled in, not even a repo.

[betacentauri]

So no it’s not possible. Tar file is on VU server and not in the git.

[anudanan]

So the only why to get a fix in the tar file is to inform VTI and they inform VU? Or is there a better way to do that?

 

Or can you patch the tarfile with a fixed version of plugin.py?

[Erik Slagter]

(TS) you will find that either Kodi or HbbTV implementations for all vendors are both at least partly closed source and also implemented poorly, which makes supporting it in OpenPLi hard in various ways.

[anudanan]

Yes, you are right, the implemtations are poor ;-)

 

happy new year

[Erik Slagter]

They tend to implement just about enough to be able to support their claim for support and anything more than that. It's frustrating for us. For every new version of OpenPLi we struggle and fight to yet again get it all working. There will be a moment, though, where we can't workaround any more and we either must drop support for those for certain vendors or the vendor must fix their product.

[anudanan]

For myelf it is ok, I have a solution for me.

 

Other users may edit this plugin if they have also problems
