How to access a C pointer array from Golang

CGO: How do you use pointers in Golang to access data from an array in C

QUESTION

How to access a C pointer array from Golang

Asked 2018-Apr-24 at 13:12

I'm writing an app for the windows platform using FFmpeg and it's golang wrapper goav, but I'm having trouble understanding how to use the C pointers to gain access to an array.

I'm trying to get the streams stored in the AVFormatContext class to use in go, and eventually add frames to a texture in OpenGl to make a video player with cool transitions.

I think understanding how to cast and access the C data will make coding this a lot easier.

I've stripped out all the relevant parts of the C code, the wrapper and my code, shown below:

C code - libavformat/avformat.h

Since the library author did not construct a slice header for you to work with you will instead need to cast the return value you get to an unsafe.Pointer and then to a uintptr this will allow you to perform pointer arithmetic on it to get elements later in memory.

Here's some example code that should run as-is on the go playground.
