[PATCH] -ao pcm hintinfo message
by Ivo 20 Sep '05

20 Sep '05

Hi, This patch fixes the -ao pcm hintinfo message. It's stll saying: to write WAVE files use -waveheader which should be -ao pcm:waveheader. I'm not sure if vim preserves all the international characters used in different translations, so I didn't want to commit it right away. I could have just fixed the mp-en version, but since it should be fairly trivial to fix it for all translations at once, I thought that was silly. If somebody can assure me this is OK to commit, I will. Otherwise, tell me how I can make it work without fscking up the translations :) --Ivo
