Description

I'm trying to load some thumbnails from video file but I notice that some video formats throws a runtime exception:

W/ThumbnailUtils: java.io.IOException: Failed to create thumbnail
        at android.media.ThumbnailUtils.createVideoThumbnail(ThumbnailUtils.java:331)

        at java.lang.Thread.run(Thread.java:919) 

So I had to dig deeper to test with different video formats and for me, AVI, MPG/MPEG, and WMV throws this exception every time.

Reproduction

Load a thumbnail from the following video file formats: AVI, MPG/MPEG, or WMV.

調査方針
The issue is in LocalVideoThumbnailProducer.java (line 81) where MediaMetadataRetriever.setDataSource fails for AVI, MPG/MPEG, and WMV formats. Investigate whether these formats are unsupported by the Android MediaMetadataRetriever on certain API levels and consider adding a fallback using another library or handling the exception gracefully. Review the comments on the issue for any additional context or proposed solutions. Test on multiple Android versions to confirm the behavior.
