Clue list for clueless non-developers who want to test CVS (and other people too)

So, you want to test the bleeding edge, huh?  Perhaps your card was not supported in the released code or you want to try the latest patches you've read about in the mailing lists?  OK. Here's how to get and use the CVS code:

Downloading and installing the CVS code

Open up a console and go to the path where you want to store RivaTV from CVS and get it:
$ cvs -d:pserver:anonymous@rivatv.cvs.sourceforge.net:/cvsroot/rivatv login
[when asked for a password, simply press enter]
$ cvs -z3 -d:pserver:anonymous@rivatv.cvs.sourceforge.net:/cvsroot/rivatv co rivatv

If you have checked out RivaTV before, you can update using CVS like this:

$ cd rivatv/
$ cvs update -d

Now you have a bleeding edge version of RivaTV!  You can check the latest updates to CVS by reviewing the changelog.

Build and install in the same way as the "stable" code.  If there are errors during the build process, go to the 'Reporting Bugs' section below.  Two popular configure options also to consider are:

$ ./configure --enable-software-conversion --enable-agp

When the rivatv module is initialised, it sends a lot of information to your system log. Where exactly it is logged to, you can determine by examining your /etc/syslog.conf. With most distributions, it is either /var/log/messages or /var/log/syslog. Additionally, the dmesg command will probably show it too.  An example excerpt from a log:

You are now ready for testing!


Start xawtv, or a similar application. It will likely complain about some stuff. That's OK.

Remember the video stream you were seeing in windows? Compare that to what you are seeing now. Play with the settings.

You may not see anything. The picture may have a low framerate, be too small, too large, that sort of thing.

All things you are seeing that are different from windows are relevant.

If you aren't seeing anything, you may want to check first if we have actually started working on your nVidia chip already! Because if not, we know it doesn't work as well.

If you are trying framegrabbing, also called capturing, things might be too slow for you. In that case, it is time for you to become an advanced tester!  RivaTV supports an experimental feature called DMA, which is turned off by default. To enable it, you have to load RivaTV like this:

	# insmod rivatv.o dma=1

Linux or X may crash. If your filesystem is not a journalling one (such as ext3, reiserfs, ...), make sure all your precious data is written to disk. For instance, by running sync.

Reporting Bugs

You have seen what RivaTV does, and think there's something wrong.
You have read the FAQ and mailinglist archive, and are pretty sure you are not to blame.
Very well, send a bug report to rivatv-devel@lists.sourceforge.net
What we want to know: To record the output of RivaTV, you can use this command:
 # tail -0f /var/log/messages > rivatv.log

Do this before you modprobe any rivatv module.

Think twice before sending a big load of information to the list. Send big stuff only when asked.

Instead of the jokingly mentioned credit card number, you could lend us hardware. It would speed up development for that particular type of board. See the FAQ for more details.


You are now a RivaTV certified non-clueless tester. Thanks for helping out!
