### Install SDWebImageAVIFCoder with CocoaPods

Source: https://github.com/sdwebimage/sdwebimageavifcoder/blob/master/README.md

Install the SDWebImageAVIFCoder pod. Default uses the 'aom' AV1 codec. Subspecs can be used to select alternative codecs like rav1e, dav1d, libgav1, or SVT-AV1.

```ruby
pod 'SDWebImageAVIFCoder'
```

```ruby
pod 'SDWebImageAVIFCoder'
pod 'libavif', :subspecs => [
  'libdav1d',
  'librav1e'
]
```

```ruby
pod 'SDWebImageAVIFCoder'
pod 'libavif', :subspecs => [
  'libgva1',
  'SVT-AV1'
]
```

--------------------------------

### Install SDWebImageAVIFCoder with Swift Package Manager

Source: https://github.com/sdwebimage/sdwebimageavifcoder/blob/master/README.md

Add the SDWebImageAVIFCoder Swift Package Manager dependency. The SPM version only supports the 'aom' codec.

```swift
let package = Package(
    dependencies: [
        .package(url: "https://github.com/SDWebImage/SDWebImageAVIFCoder.git", from: "0.5")
    ]
)
```

--------------------------------

### Choose AVIF Codec at Runtime (Swift)

Source: https://github.com/sdwebimage/sdwebimageavifcoder/blob/master/README.md

Force the use of specific AV1 codecs for decoding and encoding AVIF images. Pass these options at the UI level when setting an image.

```swift
let decodeOptions: [SDImageCoderOption: Any] = [.avifDecodeCodecChoice: AVIF_CODEC_CHOICE_AOM.rawValue]
let encodeOptions = [SDImageCoderOption: Any] = [.avifEncodeCodecChoice: AVIF_CODEC_CHOICE_RAV1E.rawValue]

// Pass from UI level options
imagView.sd_setImage(with: url, placeholderImage: nil, options: [], context: [.imageDecodeOptions: decodeOptions, .imageEncodeOptions: encodeOptions], progress: nil, completed: nil)
```

--------------------------------

### Choose AVIF Codec at Runtime (Objective-C)

Source: https://github.com/sdwebimage/sdwebimageavifcoder/blob/master/README.md

Force the use of specific AV1 codecs for decoding and encoding AVIF images. Pass these options at the UI level when setting an image.

```objective-c
NSDictionary *decodeOptions = [SDImageCoderAVIFDecodeCodecChoice: @(AVIF_CODEC_CHOICE_AOM)];
NSDictionary *encodeOptions = [SDImageCoderAVIFEncodeCodecChoice: @(AVIF_CODEC_CHOICE_RAV1E)];

// Pass from UI level options
[imageView sd_setImageWithURL:url placeholderImage:nil options:0 context:@{SDWebImageContextImageDecodeOptions: decodeOptions, SDWebImageContextImageEncodeOptions: encodeOptions} progress:nil completed:nil];
```

--------------------------------

### CocoaPods: Use libavif with libgav1 codec

Source: https://github.com/sdwebimage/sdwebimageavifcoder/blob/master/README.md

To enable libavif support with the libgav1 AV1 decoder using CocoaPods, specify the 'libavif/libgav1' subspec.

```ruby
pod 'libavif/libgav1'
```

--------------------------------

### CocoaPods: Use libavif with dav1d codec

Source: https://github.com/sdwebimage/sdwebimageavifcoder/blob/master/README.md

For CocoaPods users, to integrate libavif with the dav1d AV1 codec, use the 'libavif/libdav1d' subspec.

```ruby
pod 'libavif/libdav1d'
```

--------------------------------

### CocoaPods: Use libavif with rav1e encoder

Source: https://github.com/sdwebimage/sdwebimageavifcoder/blob/master/README.md

For CocoaPods integration with the rav1e AV1 encoder, use the 'libavif/librav1e' subspec. Note that this subspec uses a pre-built static-linking binary.

```ruby
pod 'libavif/librav1e'
```

--------------------------------

### Add SDImageAVIFCoder to Coders Manager (Swift)

Source: https://github.com/sdwebimage/sdwebimageavifcoder/blob/master/README.md

Register the shared SDImageAVIFCoder instance with the SDImageCodersManager to enable AVIF image loading. Then use the standard image loading methods.

```swift
let AVIFCoder = SDImageAVIFCoder.shared
SDImageCodersManager.shared.addCoder(AVIFCoder)
let imageView: UIImageView
imagView.sd_setImage(with: url)
```

--------------------------------

### CocoaPods: Static Framework Linkage for librav1e

Source: https://github.com/sdwebimage/sdwebimageavifcoder/blob/master/README.md

When using the librav1e encoder with CocoaPods, especially for framework package formats, ensure static linkage is specified. This is required because librav1e on CocoaPods uses a pre-built static-linking binary.

```ruby
use_frameworks! :linkage => :static
```

--------------------------------

### CocoaPods: Use libavif with aom codec

Source: https://github.com/sdwebimage/sdwebimageavifcoder/blob/master/README.md

To use the libavif library with the aom AV1 codec via CocoaPods, specify the 'libavif/liaom' subspec.

```ruby
pod 'libavif/liaom'
```
