Using seekTo() on a ExtractorMediaSource with a local mp3 file will cause a Source Error at the end of the file if a seek was ever preformed that went outside of the buffered region. If all seeks are done within a region that has already been buffered then this exception won't occur. If the ExtractorMediaSource is used within a ConcatenatingMediaSource, this error will cause the ConcatenatingMediaSource to not play the next media source. I first encountered this in my app but I managed to reproduce it in the demo app by altering some of the code. I changed media source in PlayerActivity to only play my local audio files:

MediaSource mediaSource = ExtractorMediaSource(Uri.parse(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI.toString() + "/" + 1854), mediaDataSourceFactory, new DefaultExtractorsFactory(),
              null, eventLogger);

The exception produced is:

I think this is caused by incorrectly calculating the number of bytes remaining when using ContentDataSource, which means that reaching the end of the stream is not detected.

The bytesRemaining didn't always take into account any skipped bytes, which
meant that reaching the end of the file was not correctly detected in read().

* Restore the interrupted flag after blocking operations

If the main thread was interrupted during
ExoPlayerImplInternal.blockingSendMessage/release, the interrupted flag was
immediately set but then wait() was called on the next iteration. wait() would
immediately throw InterruptedException, causing the main thread to spin until
the blocking operation completed.

Instead of resetting the flag immediately, reset it after the blocking
operation completes.

Make getMediaFormat protected so that subclasses can set additional MediaFormat

COLOR_FormatYUV420Flexible.

* Allow more aggressive switching for HLS with independent segments

We currently switch without downloading overlapping segments, but
we do not actually switch more aggressively. This change fixes
this. Note there's an implicit assumption made that if one media
playlist declares independent segments, the others will too. This
is almost certainly true in practice, and if it's not the penalty
isn't too bad (the player may try and switch to a higher quality
variant one segment's worth of buffer too soon).

we want certain attributes to be passed through. This lets you

custom ones.

Not sure if there's a cleaner way to do this. Pragmatically this
solution seems ... ok :)?
