h264 constrained baseline profile

[chetanbnaik]

Hello,

Currently rpicamsrc supports three kind of profiles. {baseline, main, high}
However, the mmal interface is also capable of generating constrained-baseline type of profile. Could it be useful to have this option included in rpicamsrc?

Also, is there any way we can control the profile-level-id parameter of rpicamsrc, specially the level-idc?

If you give me some pointers, I can also try helping.

I tried some changes, and have enabled the option to create an encoder with a baseline profile. However, when I try to modify the level less than 4, mmal encoder throws an error.

at the moment, it seems the profile level < 4 is not supported by mmal.
