Stream #0.2(eng): Audio: aac, 48000 Hz, 5.1, s16
it's a 5.1 source, and the audio encoder can only do 2.0 with AAC HE and AAC HE+PS. You must use AAC LC for multi-channel audio. I'll try to add a "6to2" downsample in the next release. Also, 128kbps AAC LC 5.1 channel sounds like cr*p . I'll add 192kbps.

[edit]

ffmpeg cannot downmix (5.1 -> 2.0). You'll have to use AAC LC with a high bitrate.

[edit 2]

faac (1.28) fails to encode 6channels, but it works with nero. I'll remove FAAC and use ffmpeg instead.

[edit 3]

this update will take some time.. I'll update the whole audio part to pipe ffmpeg to the other encoders, so I'll only have 1 step (encoding) instead of extracting then encoding.

Using the 101229_dev build batch encoding seems broken, just stops after one file unlike the previous build. I can press start again and it goes to the next file on the list.

Using 20101229dev, both files in the queue encoded successfully. Sorry, I cannot reproduce your problem.

both version doesn't have the same encoding options and won't produce the same quality. Choose "MQ" or "LQ" in the newer release.

[edit]

I'm wondering.. is bencos.exe using CPU while encoding on your PC?

On the todo now:
* Encode by file size
* Multi track (audio)
* Web view (basic, online, to see the main log + realtime status text)

With neroAacEnc it work perfectly but without it i got an error like

FAAC 1.28

Couldn't open input file C:\DOCUME~1\Age080\LOCALS~1\Temp/bencos/audio.mp4"C:\DOCUME~1\Age080\LOCALS~1\Temp/bencos/audio.wav
Source = 6 channel
I use AAC LC 192

Is there no way to downmix 6channel to 2 channel... i want to use AAC HE+PS/64 with normalization for small size encoding.

5.1 encoding works now with AAC LC and Vorbis. ffmpeg cannot downmix proprely 5.1 to 2.0.
I'm making a release..

just curious since your using ffmpeg for most of the encoding does ffmpeg handles VFR content well like handbrakeCLI is?

and can you add CRF mode of encoding?
