Video and UDP Workflows

OpenISAC can carry UDP payloads over the OFDM communication link. Video demos usually feed compressed packets into the same payload path.

Bring-up order

First validate the PHY with low-rate traffic. Then increase UDP payload rate. Finally add video encoding or decoding tools after link stability is confirmed.

Debugging

Separate PHY failures from application failures:

• If synchronization is unstable, fix the radio path first.
• If LDPC decode fails, inspect channel and offset estimates.
• If UDP drops occur with stable decode, inspect queues, datagram size, and application pacing.
• If video freezes but UDP arrives, inspect codec and player behavior.

This ordering prevents frontend or application symptoms from being mistaken for radio problems.
