808 Keychain camera information index.

A LOT of information about the camera at chucklohr.com

Parts:

• Replacement battery suggested by ri0grand

Mods:

• Running the camera off of a RX.
• Time lapse with the keychain camera by replacing a crystal.

Other Information:

• The protection circuit on the lipo battery
• Recharging at the field. Also available on Amazon.

One tip from me: Tie a string from the camera to the plane. Mine fell off its velcro on its second flight.

If there is something you want me to add to this list email me at t0ny-(a)-t0ny.org replace the -(a)- with a @.

FFMPEG problem

With FFMPEG when I try to compress the video I get this error:

[mpeg4 @ 0x101812800]timebase not supported by mpeg 4 standard
Error while opening codec for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height

I found a simple solution to this problem. All you need to do is tell it the FPS you want. Add this to your FFMPEG command.

-r 29.97
