Apple's Photo.app has no problem playing the audio from some videos (for example, videos recorded by an iPhone). But it does not play the audio from videos created by an Olympus SZ-31MR digital camera.
These videos do play within Photos, but they are silent.
When played in Quicktime Player (and VLC), the audio plays correctly.
According to Quicktime Player, videos from this camera are encoded as "H.264, 1920 × 1080, Millions; 16-bit Integer (Little Endian), Stereo, 32.000 kHz"
This is in OS X El Capitan (10.11.2) and Photos.app 1.3 (350.23.0), but the problem is not new. This thread on discussions.apple.com claims the problem is the audio codec used by the Olympus camera.
Is there a way in which I can play these videos and get sound, without having to find the individual video files and open them in Quicktime.app? Any of the following solutions would be acceptable:
- Some kind of install (a Quicktime plugin?) that fixes the behaviour in Photos.
- An alternative photo browser that can import (or view in place) the Photos library and which can play the audio in these videos. (I've tried Lyn, but that has the same behaviour as Photos.)
- Some way of transcoding these videos so that the audio plays in Photos. I have lots of videos and import new videos regularly, so a convenient interface would be important here.
