encoder ‘aac’ not working

[Jim Sustacek]

This binary does not have libfaac, sorry. But it does have libx264 and libmp3lame — the author has posted his compile command here:

Personally, we’ve been using FFMPEG’s built-in AAC encoder with “-strict experimental” and it’s been working great for us. Definitely try it in your workflow and see if it works for you first — it sure beats trying to compile your own!

[Peter Robertson] ” Thanks. So the precompiled binary will have libx264, libfaac and libmp3lame?”

Not with libfaac (same with libfdk_aac or libaacplus). It requires the ffmpeg configure option of “–enable-nonfree” and therefore the resulting ffmpeg binary is non-distributable.

[Peter Robertson] “Another question–anyone running ffmbc? I want to be able to transcode HDV to ProRes.”

ffmpeg can encode to ProRes too:
ffmpeg -i input -c:v prores -profile:v 0 -c:a pcm_s16le output.mov
The “-profile” option will determine the specific ProRes type:

• 0 proxy
• 1 lt
• 2 standard
• 3 hq

What’s the difference? See the Apple ProRes White Paper.

Also see the FFmpeg and AAC Encoding Guide at the FFmpeg Wiki for examples and details on each AAC encoder supported by ffmpeg.

just compile with libfaac and it will overwrite the old version.
