Unity crashes on "-[AVFoundationMediaLoader GetNumAudioChannels:]" when entering Play Mode



Repro steps:
1. Open QA attached project "repro_1104510"
2. Create an empty GameObject
3. Add a VideoPlayer Component to it
4. Attach the clip from the Project Window to it
5. Enter Play Mode

Actual: Editor crashes

Reproducible with: 2017.4.16f1, 2018.2.18f1, 2018.3.0b12, 2019.1.0a10

Fixed in: 2019.2.0a10
Backported to: 2019.1.0b10

  1. Resolution Note (fix version 2019.1):

    Only happens on OSX, with movies that have audio tracks using unsupported codecs such as AMR. The usual codec (AAC) works fine. Workaround is to re-encode audio to AAC. Crash happens only if the VideoPlayer UI is visible so hiding the VideoPlayer is another - although less interesting - workaround.
