AAC encoder

[GoogleCodeExporter]

Hi, I`m working on transcoding streams from Red5 to H264, and the MP4Reader
class need a "audio" and a "video" streams on the file.

As the FAQ says, we need to encode audio with AAC to flash understand the
stream.

Link for FAQ:
http://jira.red5.org/confluence/display/codecs/h264+FAQ

Thanks SO Much,
Long life for Xuggle ;)

Hi Tiago,

Can you try encoding with mp3... I think the h264 container should still support
that.  I'll add aac to the queue, but it may be a while.

Art, thanks for response, I tryed to use mp3, see the error:

Seems stream 1 codec frame rate differs from container frame rate: 1000.00 
(1000/1)
-> 48.75 (195/4)

Do you think that it's not related with mp3 codec, but with any other option?

With -an (no audio) it works.

Forget, it´s working, I was reading inexistant file.

With -acodec libmp3lame -ar 44100 -ab 96k, worked, I'll try the file in red5-0.9
alpha now.

Thanks

Thanks; keep me posted.  Accepting feature request (but no estimated version 
it'll
ship in).

according to ffmpeg-developers, libfaac is the current best way to go.

Didn´t work, I'll build ffmpeg with the codec to test, and wait for the patch 
on
xuggle to proceed, many thanks!

Um, done as of r247 and will be in 1.23.

For Linux and Mac, build from tip of tree.  For a pre-release version for 
Windows,
take the latest Windows auto build:
