Summary

When merging with ffmpeg using the -M / --mux-after-done option, the files are not merged correctly and only audio or video files are output for some addresses.
This problem is occurring in v0.1.8-beta.
Probably related to the following commit: 2e6d10d .

1. Examples of unexpected behavior (different from previous versions)

This HLS address
Output file contains only audio.
I assume that the map is not specified correctly because video and audio are aggregated to the same address.

Commands that do NOT work correctly

2. Example of correct behavior (same as previous versions)

This HLS address
Output file contains audio and video.
I assume that the map is correctly specified because the video and audio are at separate addresses.
