The issue you're facing, where your web platform receives frequent short-length H264 data packets even when there is no screen change, can potentially lead to performance degradation due to the unnecessary decoding and rendering of this data.
The reason for this behavior may not be directly related to the screen change itself but could be attributed to other factors such as the configuration of your RDS environment and the specific version of Windows being used.
It's important to note that short-length H264 data packets are not abnormal in themselves and can occur for various reasons. One possibility is that the xfreeRDP library you're using may be sending incremental updates for small portions of the screen to minimize bandwidth usage. These incremental updates are typically referred to as "delta frames" and are sent even when there is no significant screen change to ensure a smooth visual transition.
To resolve this problem, you can explore the following steps:
- Review RDS Configuration: Verify the configuration of your RDS environment, specifically focusing on any settings related to screen encoding and compression. Ensure that these settings are optimized for performance and bandwidth usage.
- Check xfreeRDP Library Configuration: Examine the configuration options of the xfreeRDP library to determine if there are any settings related to sending incremental updates or adjusting the frequency of data transmission. Experimenting with different settings may help reduce the amount of short-length H264 data being received.
- Update or Change Windows Version: Consider updating the version of "Windows 10 Enterprise for virtual desktop" to the latest available version or try using different versions such as "Windows Server 2019" or "Windows Server 2020" to see if the issue persists. It's possible that the particular version you're using may have some compatibility or configuration issues that are causing the abnormal H264 data behavior.
- Network Monitoring: Monitor the network traffic between the xfreeRDP library and the RDS server to gather more data about the nature of the short-length H264 data packets. This information can provide insights into the patterns and frequency of these packets, potentially uncovering any underlying causes or patterns.
In summary, to resolve the issue of receiving excessive short-length H264 data on your web platform, you should review the configuration of your RDS environment, explore xfreeRDP library settings, consider updating or changing the version of "Windows 10 Enterprise for virtual desktop," and monitor network traffic to gather more data.
