Converting mp3 stream to ogg vorbis about node-fluent-ffmpeg HOT 2 CLOSED

Wow, after installing libogg and libvorbis, then configuring with --disable-encoder=vorbis --enable-libvorbis and reinstalling ffmpeg as well as using .withAudioCodec('libvorbis'), audio quality is super-great and the file size went from 5MB to... 1.9MB. Insane. From 28MB to 2MB by using a different codec library, with exactly the same settings (44100Hz, 128Kbit/sec etc.).

Two slight worries though, maybe you can help here:

1. I'm getting [mp3 @ 0x1993400] max_analyze_duration 5000000 reached at 5015510 as part of the err output, yet conversion seems to go fine. The output file is complete as well (duration is the same).

2. There err parameter always seems to be filled with a complete log, even if there is no error (the one of the writeToStream callback. Output looks like this:

Could this be a bug?
