Downloading this ends at the muxing-stage.

I tried using the same commandline as youtube-dl with an older version of ffmpeg, resulting in the same error.

ffmpeg -y -i "Adam Curtis, HyperNormalisation-p04b188g.fstream-uk-iptv_streaming_concrete_combined_hd_mf_limelight_uk_dash-video=5070000.mp4" -i "Adam Curtis,HyperNormalisation-p04b188g.fstream-uk-iptv_streaming_concrete_combined_hd_mf_limelight_uk_dash-audio=128000.m4a" -c copy -map 0:v:0 -map 1:a:0 "Adam Curtis, HyperNormalisation-p04b188g.temp.mp4"

Using a more recent version of ffmpeg (e.g. 3.1.4), the same command works fine.

Using a more recent version of ffmpeg (e.g. 3.1.4), the same command works fine.

You've got it. If you need to use a different ffmpeg than the default one, --ffmpeg-location is helpful.
