These are often the same for image tracks, since we usually drop the whole image file (both the container and actual encoded image bytes) into a single sample, but there are cases where we emit a track with `containerMimeType=image/jpeg` but **no** samples (from `JpegMotionPhotoExtractor`, to carry some metadata about the image + video byte offsets). It's therefore more correct to implement the `supportsFormat` check based on `sampleMimeType`, so that these 'empty' image tracks are not considered 'supported' by `ImageRenderer`. #minor-release PiperOrigin-RevId: 604672331
