convertBGRA8888 function Null safety
- List planes,
- NativeDataStruct data
Converts BGRA8888 to BGR888 format (removing the alpha channel), the result can be passed to VideoWorker.
Implementation
void convertBGRA8888(List<Plane> planes, NativeDataStruct data) {
final plane = planes[0];
int totalBytes = (plane.bytes.length / 4 * 3).toInt();
if (data.size != totalBytes) data.resize(totalBytes);
int byteOffset = 0;
for (int i = 0; i < plane.bytes.length; i += 4) {
data.bytes![byteOffset + 0] = plane.bytes[i + 0];
data.bytes![byteOffset + 1] = plane.bytes[i + 1];
data.bytes![byteOffset + 2] = plane.bytes[i + 2];
byteOffset += 3;
}
