Changing AVB stream channel amount during runtime
Posted: Wed Apr 11, 2018 9:39 am
Hello!
I have a quick question regarding setting AVB channel counts.
In the current XMOS AVB implementation, it seems we are only able to statically set the amount of channels per streams at compilation. This happens in avb_conf.h here.
Has anyone tried changing the code to manage variable stream channel counts that can be changed during runtime?

Code: Select all

#if AVB_DEMO_ENABLE_LISTENER

#define AVB_NUM_LISTENER_UNITS 1
/** The total number of media outputs (typically the number of I2S output channels). */
#define AVB_NUM_MEDIA_OUTPUTS 24
/** Enable the 1722.1 Listener functionality */
#define AVB_1722_1_LISTENER_ENABLED 1
