Bug#982636: cheese: creates invalid and extremely long video files

[Sergio Villar Senin]

Package: cheese
Version: 3.38.0-3
Severity: grave
Justification: renders package unusable

Dear Maintainer,

   * What led up to the situation?

Open cheese and record a video.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Record a video. Stop the recording. Double click on the thumbnail to
play the video.

   * What was the outcome of this action?

1. During the recording the video freezes after some seconds.
2. The video length shown in the UI is nonsensical, after some seconds
it shows 19 minutes.
3. The generated video is absurdly long (like the 19 minutes mentioned
before) and it's empty, it shows nothing.

   * What outcome did you expect instead?

Recording should be fine.
