Field Documentation

avtp_time_t* media_q_item_t::pAvtpTime

In a talker process this is the capture time.

In a listener process this is the presentation time (AVTP timestamp).

Examples:

openavb_intf_echo.c.

void* media_q_item_t::pPubData

The structure of this memory will be defined per mapper in a public header.

This is the common data payload format that mappers and interfaces will share.

Examples:

openavb_intf_echo.c.

U32 media_q_item_t::readIdx

Read index.

User managed. It will be reset to zero when the item is pushed and pulled.
