error, raw2adpcm_ffmpeg.bat from isomake 2.4 does not work

[shwoaps]

Код:

SET PATH=sys
For %%1 in (*.raw) do (
    echo Adding WAV header to %%1
    raw2wav.exe "%%1" "%%1.wav"
    echo Converting PCM to ADPCM (Yamaha)...
    ffmpeg -i "%%1.wav" -map_metadata -1 -c adpcm_yamaha "%%1:~0,-4%"
)

Same problem on winxp, and win7.

Код:

ffmpeg -i "%%1.wav" -map_metadata -1 -c adpcm_yamaha "%%1:~0,-4%"

what does [:~0,-4%] mean? is this correct form? i get error:

Код:

[NULL @ 0280c160] Unable to find a suitable output format for 'track04.raw:~0,-4 'track04.raw:~0,-4: Invalid argumen

-----------
my fixes:

Код:

raw2wav.exe "%%1" "%%1.wav" -> raw2wav.exe "%%1" "%%1".tmp 2 44100 16

(or it won convert anything)

Код:

echo Converting PCM to ADPCM (Yamaha)... -> echo "Converting PCM to ADPCM (Yamaha)..."

- need "" or i get errors in winxp
