How can I configure the bitrate/sample size of a PCM audio I want to add
to a video? Mencoder seems to default to
AUDIO: 8000 Hz, 1 ch, s16le, 128.0 kbit
and for the life of me, I can't figure out how to get it to use
AUDIO: 8000 Hz, 1 ch, u8, 64.0 kbit
instead. Okay, here's what I've done so far: I have an audio file,
sound.wav, which has the correct bitrate:
$ mplayer sound.wav
...
AUDIO: 8000 Hz, 1 ch, u8, 64.0 kbit/100.00%
...
And a have a video with no sound, nosound.avi:
$ mplayer nosound.avi
...
AVI: No audio stream found -> no sound.
...
Now, let's use mencoder to add the audio to the video:
$ mencoder nosound.avi -oac pcm -ovc copy \
-audiofile sound.wav -o withsound.avi
...
Audio stream: 128.000 kbit/s (16000 B/s)
...
See? Mencoder used 128kbits, although the audio file has 64kbits. And
the resulting .avi has 128kbits as well:
$ mplayer withsound.avi
...
AUDIO: 8000 Hz, 1 ch, s16le, 128.0 kbit/100.00%
(ratio: 16000->16000)
...
Is there any way I can convince mencoder to use the bitrate/sample size
of the .wav file I've provided as input?
Thanks for any help ...
