A video player for React Native with controlsA React component for displaying different types of images, including network images, static resources, temporary local images, and images from local disk, such as the camera roll. This example shows fetching and displaying an image from local storage as well as one from network and even from data provided in the 'data:' uri scheme. Note that for network and data images, you will need to manually specify the dimensions of your image! ImageResizeMode is an Enum for different image resizing modes, set via the resizeMode style property on Image components. The values are containcoverstretchcenterrepeat. When the image has rounded corners, specifying an overlayColor will cause the remaining space in the corners to be filled with a solid color. This is useful in cases which are not supported by the Android implementation of rounded corners:. A typical way to use this prop is with images displayed on a solid background and setting the overlayColor to the same color as the background. When the image is resized, the corners of the size specified by capInsets will stay a fixed size, but the center content and borders of the image will be stretched. This is useful for creating resizable rounded buttons, shadows, and other resizable assets. More info in the official Apple documentation. Similarly to sourcethis property represents the resource used to render the loading indicator for the image, displayed until image is ready to be displayed, typically after when it got downloaded from network. Invoked when a partial load of the image is complete. The definition of what constitutes a "partial load" is loader specific though this is meant for progressive JPEG loads. Android only. When true, enables progressive jpeg streaming. The mechanism that should be used to resize the image when the image's dimensions differ from the image view's dimensions. Defaults to auto. This should be used instead of scale when the image is much larger than the view. Compared to resizescale is faster usually hardware accelerated and produces higher quality images. This should be used if the image is smaller than the view. It should also be used if the image is slightly bigger than the view. Determines how to resize the image when the frame doesn't match the raw image dimensions. Defaults to cover.
What are Video Thumbnails, and Why Do They Matter?
They can effectively be viewed as lists, detailed lists, tiles or different size icons. When certain images and video files are viewed as icons, instead of a generic file type icon you will see a thumbnail preview image from the content of the file. A video thumbnail will be a still frame taken at random from near the start of the video. Support for displaying video thumbnails has increased with each new Windows release as new video formats become integrated by default. Windows 10 can show Matroska MKV thumbnails as standard and has better MP4 support although there are still several video formats that no version of Windows supports out of the box. If the format is not supported your thumbnail will be a standard icon for that file type or a blank icon. For that, you will need an extra piece of software. Here we show you some dedicated tools and video codec packs that can add thumbnail preview images for dozens of extra video types. Media Preview not just helps you display thumbnails for several video formats but also for a number of image and audio formats as well. During install, you can opt out of the image and audio shell extensions if they are not required. After install the Media Preview Configuration window will popup to allow selecting which formats to include. Simply use Select All if you want to use all supported formats and optionally add custom extensions below. Use the Restore button to reset the system back to default settings. The Settings tab is for choosing the quality of the thumbnail image. For faster thumbnail generation or to help a low end computer, adjust the setting more towards speed. You can also choose to remove the video reel or frame overlays from the thumbnail which helps gain a bit more speed. If overlays are not displaying correctly in all thumbnails use the Fix Thumbnail Type Settings button. Media Preview will automatically try to seek to a suitable frame in the video to display. The Cached vs Generated option does have a bug displaying the images though. Download Media Preview.

How To Create The Perfect Video Thumbnail
React Native provides a unified way of managing images and other media assets in your Android and iOS apps. To add a static image to your app, place it somewhere in your source code tree and reference it like this:. The image name is resolved the same way JS modules are resolved. In the example above, the packager will look for my-icon. Also, if you have my-icon. You can also use the 2x and 3x suffixes to provide images for different screen densities. If you have the following file structure:. If there is no image matching the screen density, the closest best option will be selected. Note that image sources required this way include size width, height info for the Image. If you need to scale the image dynamically i. The require syntax described above can be used to statically include audio, video or document files in your project as well. Most common file types are supported including. See packager defaults for the full list. You can add support for other types by adding an assetExts resolver option in your Metro configuration. A caveat is that videos must use absolute positioning instead of flexGrowsince size info is not currently passed for non-image assets. This limitation doesn't occur for videos that are linked directly into Xcode or the Assets folder for Android. If you are building a hybrid app some UIs in React Native, some UIs in platform code you can still use images that are already bundled into the app. For images included via Xcode asset catalogs or in the Android drawable folder, use the image name without the extension:. These approaches provide no safety checks. It's up to you to guarantee that those images are available in the application. Also you have to specify image dimensions manually. Many of the images you will display in your app will not be available at compile time, or you will want to load some dynamically to keep the binary size down. Unlike with static resources, you will need to manually specify the dimensions of your image. It's highly recommended that you use https as well in order to satisfy App Transport Security requirements on iOS. If you would like to set such things as the HTTP-Verb, Headers or a Body along with the image request, you may do this by defining these properties on the source object:. You can use the 'data:' uri scheme to use these images. Same as for network resources, you will need to manually specify the dimensions of your image. In some cases you might only want to display an image if it is already in the local cache, i.
