%%%Blender crashes when exporting a video that uses the Theora video codec and Vorbis audio codec.
This is applicable for example when creating a video sequence with audio in the VSE.

Blender can manage the Theora export without problems when using a lossless audio codec like FLAC, but when using others like MP3, Vorbis, AAC or PCM, it crashes.
I made several tests to make sure that the problem isn't the manual configuration, at regular rates and normal values.

This is the procedure I taken in the main test:

Added some images strips.
Added one MP3 audio input (First test).
Selected Xvid in the Output panel
Selected OGG as video container
Selected Theora as Video Codec.
Video Bit-rate at 9000.
GOP Size: 3 images (1: I image, 2: P image, 3: I image)
Video Rate: As default. Max Rate set at 14000
Selected Vorbis as Audio Codec.
Bit-rate at 192 (First test), 45 (Second test)
Other audio values as default.

The result is an inmediate crash when pressing the "Animation" button.
Other tests included import a Vorbis audio, so Blender doesn't have to convert, but the result was the same: crash.
Tried other formats like AAC or PCM: crash. Only FLAC worked for me.
Some audio codecs reports messages in the Properties Bar: Error initializing audio stream.
Theora in itself doesn't have any problems. The bug appears when mixing with audio.

System:
Linux Mint 11
RAM: 4GB
Quad-core: AMD 3.2Ghz
Video: Nvidia 240GT
Using up-to-date build from PPA ppa:cheleb/blender-svn
Not using the own compiled version because of other problems during compilation.
All blender dependencies installed, as shown in the page "Building Blender with Scons on Linux".%%%

%%%For a proper reference, I would really insist on always testing the officially binary from blender.org too.
Then add a .blend example with the files (just keep them small, under 5 MB). That works much better and more reliable than long recipes. :)%%%

%%%yep. the problem is the same with the official build from blender.org.
I'm trying to compile the SVN to do more tests, but I'm still getting errors. I ask, could I post a file bigger than 5MB on Dropbox and make it available to you through it? I'm asking, just in any case.%%%

%%%The .blend file and a small mp3 would be easy to keep below 5 MB :)
If not possible, dropbox is fine too.

You could also test whether audio playback itself works. %%%

%%%Ok, I finally compiled the SVN through Cmake and enabled FFMPEG to do the tests. The result is the same. A crash, so there's a problem here. I'm just a regular user, not a developer, so I can't say too much about this problem.

I'll prepare an example blend and upload it today if possible.%%%

%%%Ok. I uploaded the file on Dropbox. I don't have too much time to make a new file fitting 5MB. Here's the file: http://dl.dropbox.com/u/8709880/Test.7z
The file includes all sequencer's images into the folder, because they can't be packed within the blend. The sound input in this case is an MP3, so, when you want to make "Animation", it crashes inmediately. Trying with Vorbis gives the same result.

I hope this helps the diagnosis.%%%

%%%I ran into similar problem. in my case, I'm using Blender 2.59. I added some video, and when I tried to convert it to ogg theora it would crash immediately. I am not doing audio at all. If I pick "none" for audio, it crashes. It was successful when I chose "FLAC" for audio. I'm running Fedora 15 with ffmpeg version: ffmpeg-0.7-0.3.20110612git.fc15.i686.

Please let me know if you need anymore information from me.%%%

%%%hi, i have the same problem on r39307 on Win32.

The attached blend crashes when trying to render an animation.
When switching RenderSettings.file_format to H.264 and RenderSetting.ffmpeg_audio_code to MP3 everything works fine.

%%%Is it still issue with very recent build from http://builder.blender.org/download/ ?%%%

%%%Fixed in svn rev 40785. In fact, there were two problems:

Ogg format supports only vorbis, theora, speex and flac audio codecs. Now you'll see message about unsupported configuration when try to render.
Vorbis encoder used to crash with floating point exception. Made some investigation of FFmpeg samples and FFmpeg itself and fixed it with initializing audio_stream->codec->time_base with the same value as it's done in FFmpeg. Made some tests and they worked fine, but more tests are needed.

Thanks for the report, closing now.%%%
