Subject: [PATCH 2/5] Keep video branch in NULL state

We are locking the state of video branch to NULL and move it to PLAYING
only when we start recording.

This is to avoid the 5 seconds timeout issue with qualcomm omx encoders:
If we move to NULL state without encoding any buffers then kernel driver
waits for 5 seconds until the encoding task (which is not running) to stop.
