Webcam out of sync with sound

[teacherofyoungjediknights]

When running on my slower arch linux distro, webcam was out of sync with sound.
Desktop appeared to be alright. Mrwhat made a thorough video about the issue. It appears to be -r and -framerate are not synonymous....I believe.(could be wrong/beginner/apologies)

Could you assist me in submitting a pull request to your repository, so that I can learn about using github to fix the error. If the above is correct.

Much appreciated for sharing this repository for our use.
