Using Vorbis Audio Codec in FFmpegFrameRecorder throws errors

[GoogleCodeExporter]

Using JavaCV 0.7 on Windows 8 64 bit, whenever I try to encode something using 
the Vorbis audio codec from FFMPEG it will throw errors.

The reason I’m using Vorbis for an audio codec is that it’s the only format 
supported by the HTML5 video tag when trying to do pseudo-streaming, aka 
“fast seek”.

The replication case is attached as “RecordToVorbis.java”. I tried to 
reduce it to the minimal case, so the attached example uses only audio, no 
video – after testing I discovered the problem is only related to audio and 
is independent of video settings. I have reproduced the problem just as well 
when using video and audio, as long as the audio uses Vorbis, no matter which 
video format (e.g. MP4, Ogg Theora, or WebM), and I reproduced it with every 
audio file I tested (MP3, WAV). When I test with ffmpeg.exe (without javacv) I 
don’t get any errors. 

When I run the attached sample, this is the output I see:

com.googlecode.javacv.FrameRecorder$Exception: av_write_frame() error -22 while 
writing audio frame.

Do you have any suggestions? Thanks!

It looks like libvorbis requires the same kind of hack as libx264. Should be

Hi Samuel,
Thanks! I downloaded and tested your patch and the fix works perfectly, Vorbis 
now encodes with no errors and plays fine. Thanks for the quick response and 
the fix!
