Subler does not detect DTS audio tracks in m2ts files (but does in mkv files)
Issue #392
new
When adding a m2ts file to be processed, and DTS audio tracks do not appear at all in subler. If I take the same file and convert container to mkv (e.g. with mkvmerge, not converting any streams), the same track does show up in Subler. With ffmpeg the DTS tracks show up whether it is in m2ts or mkv container. Seems like Subler should be able to detect the audio stream in both container formats. Using the latest release (1.4.3) on an iMac running High Sierra.

Subler uses AVFoundation to demux m2ts, so it supports only the formats supported by Apple.

Not sure if this should be filed as a unique issue, but I've also noticed that sometimes, but not always, Subler incorrectly detects the number of channels in the DTS stream in an mkv container. For example, a 5.1 stream was recently detected (and encoded) as stereo.
