FFMPEG h.264/avc unsupported?

[kdigit]

I am trying to get h.264/avc input to .flv using ffmpeg. Works fine on local machine, but same command line says unsupported video (h.264/avc) codec on my server.

Is there a way I can check to see if the FFMPEG install can handle h.264/avc?

avc decoding is part of libavcodec, but ffmpeg --formats should list if decoding is supported. Really comes down to how old the compile is though.

Celtic,

I am looking for the latest build of ffmpeg. The thing is i'm running version 0.4.9-pre1, build 4730 on my server and I can't convert these h.264/avc encoded mp4's but I can do it just fine using the windows executables upped by you (http://ffdshow.faireal.net/mirror/ffmpeg/).

I'm a complete n00b at this stuff, but I did notice that in the output from my server it says:
[11] => built on Jan 15 2005 15:04:50, gcc: 3.3.2 20031022 (Red Hat Linux 3.3.2-1) )

and on my windows machine (where everything works) here it says:

libavutil version 49.0.1
libavcodec version: 51.16.0
libavformat version: 50.5.0
built on Oct 8 2006 22:37:43, gcc: 4.0.3

I've been pulling out my hair all day.

Current revision is at 6693 but I believe rev4730 is still supported AVC decoding. A current build would be faster though also possible that the older decoder can't handle some HP features that your stream uses.

I would start by updating the build on your server. Do you have ssh access?

[kdigit]

Yes, I do have SSH access. How should I go about updating this? I have an entire server, but its managed, so I normally just ask my host to do these sorts of things but they say they couldn't find a tar.gz for the latest build.

[celtic_druid]

Well normally you would just do a svn checkout.
svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
Possible that there are ffmpeg tarballs somewhere though. If you play on further updates though, svn is the way to go.
