How to fill AVFrame using AvImageFillArrays(...)

[ymosleh]

Hello, I am in the process of learning Go and I am having some problems with the type conversion between Go and C.
Normally, in C I would do something like this:

av_image_fill_arrays(frame->data, frame->linesize, (uint8_t*)imgBuffer, codecCtx->pix_fmt, codecCtx->width, codecCtx->height, 1);
avcodec_send_frame(codecCtx, frame)
......

How would you translate the above to use AvImageFillArrays(...) and set the AVFrame data buffer with uncompressed frames? Also, are there any good examples of using goav for encoding?

Thanks for the help.

The way I'd do it is :

f := avutil.AvFrameAlloc()
i := avutil.AvAllocateImageBuffer(8)
avutil.AvImageFillArrays([8]*uint8{f.Data()}, [8]int32{int32(f.Linesize())}, b, ...)

Also, are there any good examples of using goav for encoding?

You can check out astiencoder which is a GO encoder framework I've implemented.
