My objective is to support a new format for audio inside mp4. hmm.. I have been looking into the code and documents, but seem to be in need of some open source help here.
(1) When a video file needs to be decoded (say an mp4); a audio and a video media-io nodes are created for it. I am trying to find out where does this happen, in which file ? ( I am refering to page 13 of Media IO developers guide / doc_mio_developers_guide.pdf ) (2) Also, when my mp4 file is parsed, the pv_player class / some node class, would find that it contains an V123 format video and A123 format audio (in the mp4 container). It should be doing some negotiation with the media io layer about these formats, to initiate the creation of right type of nodes (for V123 video and A123 audio). This negotiation happens in some setParameterSync (of PvmiCapablityConfig) call made by the node class (i am guessing the mp4 node class) ; but i need help in finding out which cpp file are we talking about exactly. I suppose knowing these would help me map the audio dec for A123 format ; to get used when i am playing such an mp4. Kindly correct me.
