Is there a Cockpit Video Recorder?
They're presently not in use. 

The accident investigators don't generally clamor for them, since there are very few questions that they can't answer with FDR and CVR readouts, where a CIR would provide useful information.  The voices proposing them as a great idea tend to come from elsewhere -- from those who think they'd be a cool idea, but who don't fully understand the capabilities investigators already have.

Pilots are, understandably, averse to the idea -- working where your every word is recorded every minute of every day isn't thrilling, but the protections for CVR recordings are pretty strong, since only transcripts (not the actual audio itself), and transcripts edited down to relevant portions only, are all that can be released, and those only in case of accidents (at least in the USA).  

Video isn't nearly so easily transcribed as audio, and any such description of moving images opens up far more possibility of subjective or dramatic interpretation of what's shown, and ample opportunity for YouTube "experts" to craft alternate - if wildly implausible - narratives. The idea of a public outcry, or an aggressive lawyer, demanding the release of the full video of a crew's last minutes, or hours, opens up the unsettling possibility that families may see a loved one's final moments in far more detail than simply transcribed words on a page.  

And let's be honest, in a full day at work, who doesn't have moments that, edited down to a few out-of-context three-second clips, wouldn't paint a poor - if utterly inaccurate - picture of who you are and how you work?

Until and unless actual accident investigators build a persuasive case for the need for such technology in our cockpits, such devices are likely to remain in the realm of the hypothetical.  There is simply no evidence that they would do anything to make aviation any safer.
