Craching on stopRecoarding

[dennismartensson]

Hi I have the media brunch up and running. When i use startRecording every thing looks okej but when I try to stop the recording it craches. Any suggestions on what I am missing? Can it be a path problem? Can I get you some more logs or do some tests that helps you solve it?

Any one have any ide about this problem? Or how I can continue to find it?

[faishal]

[dennismartensson]

Do any one from the core licode team have any ide on how to find the problem?

[dennismartensson]

@faishal Have you found a solution?

[jcague]

Is this crashing occasional?

[dennismartensson]

It have happend every time I called stop. Can I do any thing to help provide a fix for this? Any logg I can extract?

[jcague]

I had the same issue in only two tests this week. And I couldn't found the origin. Can you tell us the system, ubuntu version and if you are using 64 or 32 bits?

Thanks!

[dennismartensson]

Okej, hmm. I am using ubuntu 12.04 LTS 64 bit, I did have some problems with openssl and had to make it manually this is in issue #34

Can there be a problem with some path of some dependency?

[dennismartensson]

Sens you have a problem reproducing and I have a setup where I can reproduce please let me know what I can do to help.

[peili]

I am facing the same problem.

[faishal]

@dennismartensson No, i also try to install it on fresh setup and facing #34. :(

[lodoyun]

[faishal]
