Hi, I am letting myself known incase someone is interested in this or already has ideas on the subject. I would like to add Theora encoding to ffmpeg's libavcodec library. My goal is to add vorbis / theora / ogm output to Handbrake. Doing this at the libavcodec level appears to make the most sense as it would benefit more people. I have already made a small start. I have the configure

Hi With 32-bit Xubuntu-14.04. When I compile FFmpeg from git using speex-1.2rc1 it builds OK. When I compile FFmpeg from git using speex-git it fails to build. (speex-HEAD-78cce67) It's not a big deal, I don't mind using speex-1.2rc1. But am I doing something wrong or is there something wrong with speex-git? (I've put the details in a txt attachment to keep this email post

I am having trouble compiling ffmpeg to support speex, which didn't work with the ubuntu libspeex-dev package, but looks like it might with the Speex version 1.2rc1 tarball from http://speex.org/downloads/ How do I tell ffmpeg's configure and/or make to use the 1.2rc1 version of libspeex in /usr/local/include instead of the older debian/ubuntu libspeex-dev package in /usr/include/speex?

CentOs zoneminder users, I have been trying to install zoneminder on Centos 5.3 (2.6.18-128.1.16.el5xen) and have hit a brick wall with ffmpeg which zoneminder has as a dependancy. There were no rpm's in centos or rpmforge so I have followed the instructions on the zoneminder website for a CentOs install. I have posted a note on the zoneminder list, but have not been able to get any takers

Hi, I don't know how much of the old VP3 codebase is incorporated into Theora. I wrote ffmpeg's VP3 decoder from scratch but eventually ported in the original VP3 IDCT function. A BSD conflict cropped up that I thought I would pass along. -- -Mike Melanson <p>---------- Forwarded message ---------- Date: Wed, 10 Sep 2003 13:06:37 -0700 (PDT) From: Steven M. Schultz

I cleaned up comparison.html, making the comparison more fair and removing manufacturers that no longer have any new hardware supporting a certain format.

This is resolved: apt-get remove libspeex-dev cd ~/src/speex-1.2rc1/ ./configure --prefix=/usr make; make install cd ../ffmpeg ./configure --enable-libspeex make; make install worked; then I was able to decode a Speex .flv file: ~/flvs$ ffmpeg -i SpeexQ6R16Efalse.flv foo.wav FFmpeg version SVN-r17174, Copyright (c) 2000-2009 Fabrice Bellard, et al. configuration: --enable-libspeex

Compiling ffmpge2theora from SVN appears to die while complaining about undefined symbols? This documents my attempt to build ffmpeg2theora from SVN on Mac OS X version 10.5.7.

Hi, Attached is my patch to add theora encoding to ffmpeg's libavcodec (by using libtheora). I am requesting help to fix the bug I mention below and am seeking general comments before I submit the patch properly. Files encoded using this encoder have a problem playing in VLC. The files will not play unless "Drop late frames" has been unticked in the advanced video settings.

I come to you "hat in hand" again. For the first time in a long while I got a "Update Notification" at the bottom of my screen -- so I decided to click on it and run the update. Unfortunately I got a couple dependency errors and am not sure how to solve them. (Not even sure why I got them.) They are as follows: Missing Dependency: libavcodec.so.51 is needed by package

I have a working implementation of the new xaudio2 API in my tree. Microsoft is treating it as a replacement for dsound[1], and as a result, this new API is used by lots of recent games; see Bug 26808[2] for some examples. Most games that use the xaudio2 API use a version of Microsoft's WMA codec. Wine doesn't currently have the ability to decode this audio for playback. In order for the

If neither --enable-ffmpeg nor --disable-ffmpeg was given, try to find ffmpeg. If it wasn't found, print the warning, but don't fail. If --enable-ffmpeg was given, fail if ffmpeg is not found. If --disable-ffmpeg was given, don't print the warning, as the user already knows that ffmpeg won't be enabled. It's important that ffmpeg is not viewed as a hard requirement, as

I've run into some issues using Opus with source files in channel layouts other than the default 8. For instance, 2.1 isn't supported, so I have to either downconvert to 2.0 or upconvert to 5.1 (which usually involves adding empty channels, which prevents the playback device from upconverting to the native layout). To address this, I've put together an initial draft of an I-D I'd

https://roundup.ffmpeg.org/roundup/ffmpeg/issue1197 I had originally encountered this problem using ffmpeg2theora. I switched to ffmpeg proper in an attempt to identify where the problem was at, and found that the problem persisted. As a result I had thought this was a problem with ffmpeg, but the ffmpeg folks seem to indicate that this is specific to Theora (too much finger pointing I think.) I
