ffmpeg stream mapping, codecs, and filters

[johnnyquid]

The command line syntax for ffmpeg can be a bit confusing. My intent is to have the final output file to have the streams as follows:
0 = input file first video stream
1 = input file first audio file with no filtering
2 = input file first audio file with filtering to change pitch
3+ = input file subtitle streams (copied)

by using the ffmpeg command
ffmpeg -y -i input.mkv -i -map 0:v:0 -map 0:a:0 -map 0:a:0 -map 0:s -c:0 copy -c:1 copy -c:2 ac3 -b:2 640K -af:2 "rubberband=pitch=0.5:pitchq=quality" -c:s copy output.mkv

When I use the command above I get the following error message:
Filtergraph 'rubberband=pitch=0.5:pitchq=quality' was defined for audio output stream 0:1 but codec copy was selected.
Filtering and streamcopy cannot be used together.

Can somebody point me in the right direction to understand stream definitions? Why does -af:2 not apply the rubberband filter to only output stream 2 and the codec "copy" definitions apply only to output streams 0, 1, and the subtitles?

Try

ffmpeg -y -i input.mkv -map 0:v:0 -map 0:a:0 -map 0:a:0 -map 0:s -c:0 copy -c:1 copy -c:2 ac3 -b:a 640K -filter:a:2 "rubberband=pitch=0.5:pitchq=quality" -c:s copy output.mkv

Thanks.

I had to tweak it just a bit to work. I ended up with the following:

ffmpeg -y -i "%~1" -map 0:v:0 -map 0:a:0 -map 0:a:0 -map 0:s -c:0 copy -c:1 copy -c:2 ac3 -b:a:1 640K -filter:a:1 "rubberband=pitch=0.50:pitchq=quality" -c:s copy "%~dpn1 (modified).mkv"
