No video is recorded

[Alin Andrei]

I'm using Ubuntu 10.10 Maverick Meerkat and no video is recorded when using Kazam. Here is the terminal output:

I think this is because libavdevice52 is not installed. Please install this and try it out.

I shall update the PPA with this fix in the mean time.

[Alin Andrei (nilarimogard)]

Unfortunately that's not it:

What about libxfixes3 and libxext6?

Unfortunately I have those too already:

Some additional info: I've also tried Kazam last week (found a link on DeviantArt) in Ubuntu 10.04 Lucid Lynx and I had the exact same "Unknown input format: 'x11grab'" error.

[Alan Pope 🍺🐧🐱 🦄 (popey)]

I too am getting "Unknown input format: 'x11grab'"

Looks like a bug in ffmpeg. Have filed Bug #631103

[Andrew (and471)]

Thanks popey, hopefully this can be rectified pretty quickly :/

[Alin Andrei (nilarimogard)]

I got to work today where I'm using Ubuntu 10.04 Lucid Lynx and here it's a different error but Kazam still doesn't record any video. Here's the terminal output:

I have the same issue as above. I do have libx264 installed.

[Justin (deadite81)]

I also suffer from this problem. I'm using Ubuntu 10.10.

Here is the output from trying to record to trying to save:

http://pastie.org/1141988

It's pretty much the same as the first poster's output.

[Andrew (and471)]

Okay, the issue was with ffmpeg in Maverick (Bug #631103) and someone has found a fix. Hopefully, this can be uploaded quite soon, otherwise I will upload a version of ffmpeg, with the patch, to the PPA.

[Alin Andrei (nilarimogard)]

I highly recommend against packaging ffmpeg into the PPA. Most PPAs who packaged their own ffmpeg packaged ended up breaking all the applications that depend on ffmpeg (the packages need to be rebuilt against the new ffmpeg package).

[Alin Andrei (nilarimogard)]

Unless of course, you use the exact same ffmpeg version, but which uses the patch.

[Andrew (and471)]

Yes, that is what I would plan to do :)

There's a new issue with the release that was pushed out today:

Compiling /usr/lib/python2.6/dist-packages/kazam/version.py ...
Sorry: IndentationError: ('unexpected indent', ('/usr/lib/python2.6/dist-packages/kazam/version.py', 2, 4, " VERSION='0.1'\n"))

[Andrew (and471)]

Okay I have uploaded a patched version of ffmpeg into the PPA. It is the version of ffmpeg in Maverick (so no compatibility problems etc.), however it has x11grab enabled, meaning recording in Kazam will now work.

Please test and report any issues! :)

Great, I'll give it a try right away.

One note: please keep an eye of new ffmpeg versions in Maverick - you'll need to add them to the PPA so it doesn't break stuff.

[Alin Andrei (nilarimogard)]

I can confirm you can now record a video in Ubuntu 10.10 Maverick Meerkat!

[Andrew (and471)]

Thanks Alin, marking as fix released (I shouldn't have to watch the version of ffmpeg in maverick, as I have set it up as a daily build, merging the fix from another branch so it should always be uptodate).

(Then again, I say 'should') :D
