--- Comment #6 from Manuel López Antequera <mlopezantequ...@gmail.com> ---
I'd like to add that I have the same problem with videos from my DJI drone. I
can report the same behavior as Karol when running with and without -map 0.
It seems like there is some stream that ffmpeg does not support in DJI video
files.
I used ffprobe and ffprobe -show_streams on the file to get more info (check
below for dumps). There are 3 streams: #0 is video, #1 is some non-standard
drone metadata, and #2 is a subtitle track for telemetry. ffmpeg is choking on
#1 because of the -map 0 flag.
The documentation of ffmpeg (https://trac.ffmpeg.org/wiki/Map) reveals that
using "-map 0" will attempt to use all of the streams in the file.
Removing -map 0 initiates some sort of automatic way of picking 1 video and 1
audio stream (https://ffmpeg.org/ffmpeg.html#Stream-selection). I think this
makes sense since we have no GUI to select streams anyways.
