Starting with our 2.7.0 mobile SDK release, you can start a publisher with pre-determined video resolution and frames per seconds (fps). Before using the API, you should be aware of the following:
- Though HD video sounds like a good idea at first, from a practical standpoint you may run into issues with device CPU load on low to medium-range devices. You may also be limited by the user’s available bandwidth. Lastly, data charges for your users could run high.
- Available on the device. The actual empirical values for these parameters will vary based on the specific device. Your selection can be seen as a maximum for the resolution and frame rate you are willing to publish.
- Automatically adjusted based on various parameters like a user’s packet loss, CPU utilization, and network bandwidth/bit-rate. Rather than attempting to do this dynamically on your own, we recommend picking meaningful values and allowing OpenTok to handle the fine-tuning.
