Bug#1008840: linphone: Recording does not work due to lack of mkv support

[Rainer Dorsch]

Package: linphone
Version: 4.2.5-3
Severity: normal

Dear Maintainer,

as a side note, even though reportbug reports that there is a newer version of linphone (4.4.21-2) for stable, I cannot install it. apt does not find it, rmadison has even two entries:

rd at h370:~$ apt-cache policy linphone

But the real problem is that linphone's recording feature pretends that it works normally, but if I checked the destination folder it is empty.

If I run with --verbose, I get

[Error]Core:linphone: Cannot record in mkv format, not supported in this build.

which suggests that linphone was built w/o mkv support.

Can you confirm that?

Previously the recording were in wav format. Is it possible to switch back to wav, if mkv is troublesome?

At least the user should get a warning that the recording does not work.

Thanks
Rainer
