public class MediaStoreVideoThumbLoader extends java.lang.Object implements ModelLoader<android.net.Uri,java.io.InputStream>
InputStreams from media store video

Uris in the media store.
VideoDecoder.TARGET_FRAME is set with a non-null value that is not equal to
VideoDecoder.DEFAULT_FRAME, this loader will always return
null. The media store does
not use a defined frame to generate the thumbnail, so we cannot accurately fulfill requests for

DataFetcherrequired to decode the resource represented by this model, as well as a set of
Keysthat identify the data loaded by the
DataFetcheras well as an optional list of alternate keys from which equivalent data can be loaded. The
DataFetcherwill not be used if the resource is already cached.
Note - If no valid data fetcher can be returned (for example if a model has a null URL), then it is acceptable to return a null data fetcher from this method.
model- The model representing the resource.
width- The width in pixels of the view or target the resource will be loaded into, or
Target.SIZE_ORIGINALto indicate that the resource should be loaded at its original width.
height- The height in pixels of the view or target the resource will be loaded into, or
Target.SIZE_ORIGINALto indicate that the resource should be loaded at its original height.
public boolean handles(@NonNull android.net.Uri model)
For example, you may want multiple Uri -> InputStream loaders. One might handle media store Uris, another might handle asset Uris, and a third might handle file Uris etc.
This method is generally expected to do no I/O and complete quickly, so best effort results
ModelLoaders that return true from this method may return
