[Libav-user] Which function receive the raw data before parsing/decoding in FFmpeg

[Denis Gottardello]

Hi, I'm not a guru on FFMpeg but, according with the remuxing.c example, after 
av_read_frame you will have a Paket that could be audio or video packet.
Before the decode function that extracts a video frame or audio frame, I think you can 
manipulate it.

I have created simple RTSP player with FFmpeg(4.2.2) in C and want to understand what 
function in the FFmpeg source code does listen for incoming data before the parsing or 
decoding start ?
My server sends additional data that is concatenated in the begningen of the packet that i 
want to remove when receiving it by FFmpeg before doing anything else.


I have looked into the function " *av_read_frame* " inside libavformat/utils.c, but i'm not 
sure if that where it first happens.
Can someone please show me where it is ?
