Grab the latest installer and overwrite your old install and click on the Reset profiles button. Then install the 0.3.2 client by clicking this link with the N900 browser and you should be good to go.

ok will try this as well.

update: discovered I was allready running v 0.3.2

strange

Not that strange, I switched the default player from mplayer to gstreamer and it doesn't like the mp2v format. I didn't use xvid, because VLC ha(s/d) some issues transcoding xvid to xvid which lead to no video and just audio.

If you upgrade the server and reset the profiles, you get to use h264 which gives a nice video quality boost and should use less battery too. And if you don't need subtitles and have normal SD material in xvid/divx, passthrough profile should be used for unaltered video quality. And you can always revert back to mplayer playback if you put the word "mplayer" in the player field of the profile.

Re: Knots 2 - easy media streaming for most operating systems

ukki:
I have a new problem.
I added to my playlist a http stream, which is basically a php script that generates a Location() header to an actual stream. This works just fine through normal VLC, but knots crashes. The VLC starts to get the stream for a second or so, then knots stops the stream.

I got this error from the web browser, using the n900 doesn't give any clues.

Code:

In case you're wondering, adding to playlist the stream, without redirect, works fine.

Please test, it's easy to replicate.

If you enable debug, does VLC show the actual stream under inputs and not your php script? If that's the case, then Knots can't map the url to an item in the database and that causes the error. But I could probably change the way it's handled now to prevent such errors. Thanks for the report, but I'd like to see these on bug tracker instead :)

Re: Knots 2 - easy media streaming for most operating systems

I saw VLC getting the stream using a network sniffer, and like I said, adding the normal stream to knots works, adding the redirected stream to knots fails but vlc works.
I guess you're right about the mapping, I analyzed the knots output and that seems to be the problem.
Maybe a small fix so knots fetches the url before giving it to VLC, and get the final url?

Here's the knots log:

Tested and it works!

Thanks a bunch.

Re: Knots 2 - easy media streaming for most operating systems

I'm having a problem getting an updated version of the server to work for my g5 powerpc mac. I'm not sure what I am doing wrong. Any thoughts?

Re: Knots 2 - easy media streaming for most operating systems

What OS X version? You need at least Ruby 1.8.6 and VLC 0.9.4 so make sure those are installed. I've never tested Knots on PowerPC so I can't be sure it will work. To see what versions of ruby and VLC you have, try running these two commands in terminal:

Code:

/Applications/VLC.app/Contents/MacOS/VLC --version

ruby -v

/Applications/VLC.app/Contents/MacOS/VLC --version

ruby -v

VLC is 1.0.5 and ruby is 1.8.6. The prebuilt package has always worked, but when I try to use the version from github the package does not work and when I try to create osx app it builds a program that isn't supported on my architecture.
