(First time around here- love HandBrake and have used it for years, hadn't stumbled on the forum until now)
I've installed some Macs in a few bars, to play (licensed) music videos via my video player app (I'm a software developer), but I've been battling a weird issue since setting things up a couple of months ago: audio will glitch out to silence mid-video after a seemingly random amount of time, and not on the same videos each time, then the next video played is back to normal.
I've methodically tried ruling out everything that I could possibly imagine causing the issue (including playing the videos using a known-good app; VLC), and it's still happening… across four Macs, on three operating system versions
At this point, it's looking like the only constant left is that all ~1,600 music videos that are played were transcoded with HandBrake (Version 0.10.2 x86_64 (2015061100))- from super-high-bitrate, to decent-bitrate MP4s…
So, while I consider myself to be a fairly good app developer, I don't know the ins & outs of A/V formats:
I realise that the actual smarts of handling audio is in the operating system, but, does it seem possible that HandBrake-created MP4s are causing the audio glitches/drop-outs? (i.e. issues with the structure of the created video file / etc?)
For reference, here's what I've tried isolating so far:
… and here's the OS X system console message that appears like clockwork a couple of minutes after the audio starts glitching:
