Summary: aac audio codec not available in ffmpeg?
Product: ffmpeg
Version: 0.4.9
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: program
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
Although the ffmpeg spec file appears to run configure with --enable-libfaac
when the package is built for plf, it seems that the 2007.1 plf binary
(ffmpeg-0.4.9-3.pre1.7407.10plf2007.1) doesn't recognize the aac audio codec or
list it in ffmpeg -formats (the aac file format is recognized and listed,
however). Here is what I get when I try to extract and convert an audio stream
from a RealMedia file:
$ ffmpeg -y -i stream.rm -vn -f aac -ar 48000 -ab 128 -coder 0 -ac 2 -acodec
aac stream.aac
