gstreamer 1.24.5 o Ubuntu 22.04. Is this FIXME message critical?

2

The DONL field is optional in RTP streams for H.265, and if it’s missing, the depayloader has to make assumptions about the decoding order.

Can depayloader make any wrong assumptions about the decoding order if it’s missing?

3

Does it cause any observable problems in your case?

4

I have not seen any issue. Does the missing DONL field slow down decoding?
