Hi Simon,
I have just checked in qtubuntu-camera and it is indeed done this way.

Title:

Its rather important when you set the video-param-encoding-bitrate
parameter for the encoder. The code should look like
android_recorder_setParameter(recorder, "video-param-encoding-bitrate=2048");
...
android_recorder_prepare(recorder);
android_recorder_start(recorder);
The parameters are not

Title:
480p and 1080p video appear to use the same
I checked what Android does in their camera application.
Basically they seem to use an average bitrate of 12kbps in 1080p, 8kbps in 720p
and 5kbps in 480p.
We agreed that we would try to do the same.
However, once I pass the correct bitrate setting down the stack from
qtubuntu-camera, it seems

I can confirm similar results recorded on Krilin:
1080p:
1920x1080
31fps
6617kbps
8.7mb filesize
480p:
640x480
31 fps
6452kbps
8.3mb filesize
@jamesh
What would you recommend for the settings at the lower resolution? What bitrate
would be expected?
