获取AvCaptureVideoDataOutput的实际NSString availableVideoCVPixelFormatTypes [英] Getting actual NSString of AvCaptureVideoDataOutput availableVideoCVPixelFormatTypes
问题描述
我试图在AVFoundation输出上找到接受的格式：
I am trying to find the accepted formats on an AVFoundation output:
self.theOutput=[[AVCaptureVideoDataOutput alloc]init];
if ([self.theSession canAddOutput:self.theOutput])
[self.theSession addOutput:self.theOutput];
然后我就插入一个断点并且：
I am then inserting a breakpoint right after and:
po [self.theOutput availableVideoCVPixelFormatTypes]
and我明白了：
(NSArray *) $5 = 0x2087ad00 <__NSArrayM 0x2087ad00>(
875704438,
875704422,
1111970369
)
如何获取字符串值这些格式类型？
How do I get the string values of these format types?
谢谢
