Subject: [PATCH] autoadapt: improve algorithm parameters
- Reduce time during bitrate increase (to reach bandwidth limit faster)
- Increase the default bitrate value from 600 kbit/s to 800 kbit/s
- Increase maximum bitrate value from 3 Mbit/s to 6 Mbit/s (needed for high resolution, if we use a low resolution the CRF mode will lower the bitrate anyway)
