But it ignores the second input file (what was that good for?)

This isn't the ffmpeg-user list, but:
Sure, ffmpeg supports multiple outputs.

$ ffmpeg -i http://samples.ffmpeg.org/V-codecs/sn40sample.avi out.mp4 -f sdl bla

And I believe the restriction of ffmpeg (vs. ffplay) of not being able
to control the output, e.g. by skipping backwards or forwards, is quite
practical, as you don't want to do that while actually trying to dump
the same file. So ffmpeg remains the optimal solution for this, not an
ffplay hack, IMHO.

So, for the original "poster" [what do we call them on a mailing
list?]:

$ ffmpeg -i 'rtsp://192.168.178.80:554/user=admin_password=PASSWORD_channel=1_stream=0.sdp?real_stream?tcp' -c copy dump.mkv -f sdl bla
