Hi,
I'm just experimenting with video grabbing by fxtv.
Seems that mpegaudio doesn't like sox's AIFF output:
(apart from another mpegaudio problem I reported to their maintainer):
(20:30) holger@Trinity [/mnt/dos/E/Capture] sox -t raw -s -w -c 2 -r 44100
westernhagen.AUDraw -t aiff -s -w westernhagen.aiff
(20:32) holger@Trinity [/mnt/dos/E/Capture] mpeg_musicin -l 2 -p 1
westernhagen.aiff westernhagen.mp2
>>> Using Audio IFF sound file headers
Sound data is not PCM in "westernhagen.aiff".
[two of the commands the script executes].
I changed the intermediate format from AIFF to WAV and it works.
The scripts mentions the sox parameters "-s -w" as "Hack to force 16-bit
signed (PCM driver)", but it seems that it doesn't work.
Ever had problems with that?
Versions are current ports': fxtv 1.03, sox 12.17.1_1,
mpegaudio 3.9
Second.
If I choose "MPEG 3" as audio output format, mpeg_musicin is also used,
which does not support layer 3.
Regards,
Holger
