Don't know if there is official doc about this, but I often do that with no
problems. Only the file I provided gives me issues.

The sample can be downloaded from here:

Running the script I provided, you can generate the output file.

I've tested the output with ffplay and vlc 2.1.2. Both have problems with
asf and both are fine with avi, but with this sample only.

Another interesting information:
If you just remux to asf the output generated by script, you fix the issue:

ffmpeg -i intermission2.asf -c copy intermission3.asf

Output file (intermission3.asf) plays fine both on ffplay and vlc 2.1.2.
