How to make defective recordings from recordmydesktop playable

How to make defective recordings from recordmydesktop playable

I try to record my precious skype sessions with my daughter thousands
kilometers away. Sometimes it works, but the last time it sadly gave a
segmentation fault and I lost the recording. Today, I booted my computer
fresh just before the conversation and tried to record it. It apparently
worked, but the file has some error and it cannot be played.
Please suggest a linux alternative to recordmydesktop. I am very sad. That
moments in skype with my daughter are the best times in my lonely life
now. I know it is necessary that volunteers put the programs to the test
so that they help debugging them, but in this case I need something that
works.
Additionally, I there is some way to play what is in the file I recorded
today, I would be happy to try. This is the capture of the konsole during
the recording:

or whatever is missing? How?
