Describe the bug If using the FPP remote local file input, with the file on the SD card, it will play once, but not loop.

I tracked the issue down to c_InputFPPRemote::StartPlayingLocalFile(). The file to play gets passed in as a String reference to FileBeingPlayed. The first thing StartPlayingLocalFile does, is call StopPlaying(). The first time through, PlayingFile() returns false, so StopPlaying does nothing, and the file plays as expected.

However, on the second time through the loop, PlayingFile() returns true, resulting in StopPlaying to clear out the value of FileBeingPlayed, resulting in the Filename now being blank when the flow gets back to StartPlayingLocalFile.

I was able to fix the issue by passing the filename to StartPlayingLocalFile by value instead of by reference, but I think the root issue is that after the file finished playing, PlayingFile() still returns true. Even if PlayingFile() properly returns false, the fact that the filename value is cleared out from under the call to StartPlayingLocalFile is bad.

Simple fix, that doesn't change the behavior of PlayingFile():

I'm also looking for a fix on this issue. Jeff, thanks for posting the quick fix. Looking forward to a full solution.

I confirm the same issue on a DIG-QUAD with standard module and AE+ module.

Sigh. No good deed etc... I will fix this shortly. It got changed when I was looking for an issue causing flashes in the input stream.
