Confusing output from gecko-mediaplayer 1.0.6

[Kurt Freytag]

Ever since I started using gecko-mediaplayer as a plugin in Firefox (1.0.3), I've gotten the following sort of output when it loads and plays a video:

NPP_New called

A few things confuse / concern me:

1. The output reports that the plugin is "Using player backend of ''". That seems wrong
2. The output reports (twice) that item is NULL
3. The output reports that is is "Destroy[ing the] stream", even though the video plays fine

I get the same output for every video, yet *almost* every video plays without issue (sometimes a video will play without sound once but play fine the next time around).

   If I play a loop of videos for 24 or 48 hours in a row, I'll sooner or later get a popup error dialog (Ubuntu 12.04, Firefox 13) saying "Gnome MPlayer Error Failed to open (null)", but I don't know if this is in any way related.

   What I'm asking is the following:

1. Does the output above suggest that there are problems in my build / configuration?
2. Is there a reason why gnome-mplayer would throw a popup error with that message and can I fix or disable them?

Thanks,

Kurt

Hi Kurt,

Sorry, I wasn't able to get to your email yesterday.

Anyway your questions:

> 1. The output reports that the plugin is "Using player backend of
> ''".

All this means is that gnome-mplayer is being used and not some other
backend, And yes, if an application emulated the gnome-mplayer dbus
interface, then gecko-mediaplayer could use it. I guess I could clean
up that message a little. Nothing to worry about.


> 2. The output reports (twice) that item is NULL

This can happen in a couple of conditions, usually firefox is calling
method in the plugin without associated context. This is ok, just
means that we have to be generic about what we are doing at that point.


> 3. The output reports that is is "Destroy[ing the] stream", even
though the video plays fine. This is normal when we download the video
to the local disk and then play it from there, as downloading can be
faster than playback if the server is local.

NPN_DestroyStream is a plugin method that is called when the stream is
complete. Perfectly normal and in somecases exactly what we want to
do. (Reference files are examples of this).


As for the plugin crashing or getting a popup. Well sometimes that
happens. We try to reduce those that we find, but sometimes things go
wrong. If you have a site I can test against, I could try that from
here. You can email me privately if you don't want to share it with
the world.

The popups can only be disabled by modifying the code at this point.
In 1.0.7 there is a new message logging system that is being installed
and it should reduce the amount of noise output by the plugin.

Kevin -

Thanks so much for the replies.

Glad to know that it's all basically "acting normally".

Kurt,

Those messages look ok to me, although we are working at cleaning them up.

What version of the SVN code were you using?

Kevin
