Impact of Disabling DTS (Decoding TimeStamp) Verification Check for Multiple Cameras

[Shankar-Bharadwaj]

Hi everyone,

We are currently working with multiple cameras, and we encountered an issue while using the Kinesis Video Streams SDK with GStreamer. We noticed that when streaming from a specific camera, we had to disable the DTS verification check (i.e., GST_BUFFER_DTS_IS_VALID) to avoid frame drops and ensure smooth streaming to KVS.

We found a previous discussion that suggested this approach and resolved our issue by bypassing the DTS check. However, we're now concerned about the potential downsides of this change, especially since we are working with multiple cameras.

Our main concerns are:

1. Frame Synchronization: Disabling DTS verification might affect the synchronization between frames from different cameras. Is there any risk of out-of-order frames being processed or incorrect frame timestamps?
2. Long-Term Impact: Is there any long-term impact on stream quality or stream health when continuously bypassing the DTS check?
3. Scalability: Since we plan to scale to many cameras, could this approach cause any issues with managing multiple streams?
   I would appreciate any insights or advice regarding the potential trade-offs of disabling the DTS verification check in this scenario.

Thanks!
