M3U8 causes UnrecognizedInputFormatException when no MimeType is given

[th3infinity]

When playing a M3U8 MediaItem from Network it gives a error:
Caused by: androidx.media3.exoplayer.source.UnrecognizedInputFormatException: None of the available extractors (FlvExtractor, FlacExtractor, WavExtractor, FragmentedMp4Extractor, Mp4Extractor, AmrExtractor, PsExtractor, OggExtractor, TsExtractor, MatroskaExtractor, AdtsExtractor, Ac3Extractor, Ac4Extractor, Mp3Extractor, AviExtractor, JpegExtractor, PngExtractor, WebpExtractor, BmpExtractor, HeifExtractor) could read the stream.{contentIsMalformed=false, dataType=1}

This is caused by the empty string mimeType which is the default value for VideoPlayerMediaItems. It would be possible to set the right mimeType but that could change.

Fix:
Since the mimeType property of Exoplayer MediaItem is nullable a fix would be to allow the mimeType of VideoPlayerMediaItems to also be null.
