Description

Version

Media3 main branch

More version details

We are using media 1.9.3 currently and i can see a lot of player errors caused by following code

          Caused by java.lang.NullPointerException: Attempt to read from field 'androidx.media3.exoplayer.MediaPeriodInfo androidx.media3.exoplayer.MediaPeriodHolder.info' on a null object reference
       at androidx.media3.exoplayer.ExoPlayerImplInternal.seekToCurrentPosition(ExoPlayerImplInternal.java:1203)
       at androidx.media3.exoplayer.ExoPlayerImplInternal.reselectTracksInternalAndSeek(ExoPlayerImplInternal.java:2280)
       at androidx.media3.exoplayer.ExoPlayerImplInternal.handleMessage(ExoPlayerImplInternal.java:793)

I wonder if there is anything on our side to try to prevent this.
