Ffmpeg Amr

[Priyatam]

Hi,

How do we encode a video using the amrnb or amrwb codec by using the ffmpeg utility.

Is there any ffmpeg build for WIndows , enabled with the fixed n float point amrnb and amrwb codecs.


Thanks in Advance.

Priy.

by reading FFmpeg doc and/or man pages. It's a good start.

Hi,

Thanks for the ref Kurt
Could you also tell me the VBR Options for Audio and Video that can be used for encoding using FFMPEG.

Thanks in ADV.

AMR format with FFmpeg doesn't have a vbr switch...or I missed something.

I dont just mean for AMR .. in general for all encoding options how do we specify the VBR Options using FFMPEG.

For Audio Encoders, you can use -aq xxx; where xxx is the level quality.

For Video : depends on the encoder you choose I think.
