Comment (by burek):
Further discussion on IRC channel revealed that there is -c which is
equivalent for this -c:all suggestion, but the problem with -c (or rather
with -map) is because -map 0 is not the default behavior. So, here is the
problem. When a user types:
{{{
ffmpeg -i INPUT -c copy OUTPUT
}}}
what he is expecting is to remux his media into another container, but
what he gets is not what he was expecting, because, in a multiple streams
media file, ffmpeg will choose the "best pick" for multiple audio streams
for example and will leave other audio streams not copied.
So, my suggestion was actually to make -map 0 the default option, making
ffmpeg copy all streams, not just to pick "the best ones" out.
