Given
extern(C):
struct AVFrame
{
uint8_t*[AV_NUM_DATA_POINTERS] data;
int[AV_NUM_DATA_POINTERS] linesize;
int width, height;
...
}
void av_image_copy(ubyte *[4] dst_data, int[4] dst_linesizes,
const ubyte *[4] src_data, const int[4]
src_linesizes,
AVPixelFormat pix_fmt, int width, int
height)
will `dst_data` will be C-ABI-fed to `image_copy()` as a C-style
single pointer in constrast to what happens in D which calls it
as fixed-size (4) array of ubyte-pointers?
Further, is it correct to use it in D as
void copyVideo(const AVFrame* source,
AVFrame* target)
{
av_image_copy(target.data[0 .. 4], target.linesize[0 ..
4],
source.data[0 .. 4], source.linesize[0 ..
4],
format, source.width, source.height);
}
?
It compiles without warnings, at least. I haven't been able to
test it yet, though.
