CentOS supported codecs

VP Lists
Hi folks.

I ran a bunch of tests and found what items I need in the ffmpeg  
config to get my videos to work from iMovie.  Now I've worked up a  
CentOS application, and the faac (developer version) won't support  
these items:

FFmpeg version SVN-r11353, Copyright (c) 2000-2007 Fabrice Bellard,  
et al.
   configuration:
   libavutil version: 49.6.0
   libavcodec version: 51.49.0
   libavformat version: 52.3.0
   built on Dec 30 2007 11:55:49, gcc: 3.4.6 20060404 (Red Hat 3.4.6-9)
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x83445c0]negative ctts, ignoring
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'testIncoming.mov':

     Stream #0.0(eng): Audio: mp4a / 0x6134706D, 32000 Hz, stereo
     Stream #0.1(eng): Video: h264, yuv420p, 320x240 [PAR 0:1 DAR

Output #0, flv, to 'testcompleted.flv':
     Stream #0.0(eng): Video: flv, yuv420p, 320x240 [PAR 0:1 DAR

     Stream #0.1(eng): Audio: adpcm_swf, 22050 Hz, stereo, 64 kb/s
Stream mapping:
   Stream #0.1 -> #0.0
   Stream #0.0 -> #0.1
Unsupported codec (id=86018) for input stream #0.0


Any chance anybody knows what component I have to install?

Hi there.  Thanks for the reply.  I think it's active, but I have  
forwarded the info to the hardware sysop.

i don't know what you mean by "it's active", but if you meant that the
ffmpeg you're using is configured with --enable-libfaac, this is wrong.
the part you cut just before my reply would have shown you...

The component that was in the config, the libfaac.  I believe it was  
enabled, therefore it's active.  Since I didn't configure it, I am  
going on someone else's response.  I gave them my setup which I did  
on my Mac, which is what I put into the original posting.  That has  
it enabled, so I don't see how it could have changed, as we discussed  
it.  Like I said, I have forwarded it to him and we will discuss it.  
As well, he told me he had issues with a faac as the only version he  
could find was a developers version for his platform.

The CentOS comes with GCC 3.4.6, and I received the error in ffmpeg:

Compiler did not align stack variables. Libavcodec has been miscompiled
and may be very slow or crash. This is not a bug in libavcodec,
but in the compiler. You may try recompiling using gcc >= 4.2.
Do not report crashes to FFmpeg developers.

But there isn't any version that high.  Any idea how to get around  
this obstacle?

Cheers

This isn't an error, it's just a warning message. The problem which
underlies this message has been present for a very long time, and people
have used FFmpeg successfully in that time. This is simply a warning
that the developers will not pay much attention to bug or other problem
reports not based on a version which has this message.

Certainly there is; for the handiest one I could install if I chose,
Debian's unstable package archive currently contains version 4.2.2. I
suspect that there are more recent versions even than that if you go
directly to the developers. Your distribution and/or package provider
may not offer it yet, but that doesn't mean it doesn't exist.

> Any idea how to get around this obstacle?

Obtain a newer version of GCC from another source - if necessary, by
downloading its source code and compiling it yourself. In practice,
there are probably more practical approaches.
