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 that at some point that setting gets lost or ignored. Jim Hodapp is looking into why this happens, since he's working on that part of the stack. So far it seems that the settings is making its way down to the level of the media framework, and he is looking to find if it gets passed to the video codec properly. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to camera-app in Ubuntu. https://bugs.launchpad.net/bugs/1434517 Title: 480p and 1080p video appear to use the same bitrate Status in Canonical System Image: In Progress Status in camera-app package in Ubuntu: In Progress Bug description: I just recorded two 10 second videos of the the same object using my Nexus 4, one using the 1080p setting and the other 480p. Both videos came out at roughly 8MB, each with approximately a 6.3 Mb/s video bit rate and 96 kb/s audio bit rate. This seems a bit weird to me: the only reason I can think of to offer multiple resolutions is to let the user pick the quality / storage space trade off they want. If the lower resolution videos take up just as much space as the high resolution ones, then this doesn't make sense.
