SilenceMediaSource Error

See original GitHub issue

Hi,

I keep getting this error when trying to prepare the SilcenceMediaSource in the player, it simply fails to play.

2019-07-26 12:03:45.884 4663-5805/com.yiqqi.android.yiqqi.development E/ExoPlayerImplInternal: Internal runtime error.

This class was created under our request and we deeply appreciate it, but it seems to have this error which makes it unusable, could you please look into it? Thank you.

Yes, here’s the situation, I have a timeline, which has multiple songs and with empty gaps between them, these gaps can be at the start and end as well. for that, I use ConcatenatingMediaSoruce with ClippingMediaSource for songs and SilenceMediaSource for gaps. Here’s a representation of a simple timeline:

-song-song-song- -: SilenceMediaSource song: ClippingMediaSource with ProgressiveMediaSource

The issue is when readData happens, the byteRemaining is a negative value which shouldn’t be the case, here’s a debug screenshot up until the hightlighted line that produces the error:

This issue is that everytime I recreate the ConcatenatingMediaSoruce, even with the same values, with the same SilenceMediaSource durations and start positions for SilenceMediaSource and ClippingMediaSource. I sometimes get the error and sometime not. I tested with fixed constant values and recreated the ConcatenatingMediaSoruce again and again, it’s like a hit and miss, works a couple of times, then error, then works again, then error again…

I’m sorry as it’s hard to explain because I ran a couple of tests already and I can’t seem to track down the exact source of the issue.

Could you provide some more information on how to reproduce this error? Does it occur after seeking? I just tried playing a concatenation of some media with a SilenceMediaSource in the demo app and it worked as expected.
