Pass Meta Data from In- to Output #16
Description
Hi,
I am trying to use the vcu_ctrl_sw to decode some camera streams on our ZU4. We are using the v2022.2 stack.
Things are going well so far. However, I find one feature missing: I want to attach some custom metadata to my encoded image stream, such as Frame ID, receive timestamp and so on. And I want this meta data to be attached to the corresponding decoded frames as well. As the decoder architecture follows the asynchronous pattern, I cannot do it manually. So, I would expect, that the decoder does hand over some meta data from the input buffer to the output buffers. However, it does not.
I tried to add the various types of meta data and also to set user data. Nothing seems to be handed over. Also I could not find any attempt to copy any meta data from input to output in functions like AL_Patchworker_Transfer() and down the stack until TryCopyBufferToStream() where raw byte buffers are copied.
Is it just not intended to pass meta data from input to output or am I missing some super easy way of doing it?
