The updated ffmpeg/libav libraries are quite a big change. It would be nice if you guys could do some libav decoder testing with various codecs (AC3, E-AC3, DTS, MP1, MP2, MP3, MLP, TrueHD) to make sure that things still work as intended.
Decoding/Transcoding E-AC3 streams within spectral extension don't seem to work properly for me using libav decoder...

1/
Code:
eac3to input.ts 2:audio.ac3
Quote:
TS, 1 video track, 2 audio tracks, 2 subtitle tracks, 0:00:13, 50i
1: h264/AVC, 1440x1080 50i (16:9)
2: E-AC3, French, 5.0 channels, 256kbps, 48kHz, dialnorm: -27dB, -2140ms
3: E-AC3, qaa, 2.0 channels, 128kbps, 48kHz, dialnorm: -23dB, -2132ms
4: Subtitle (DVB), French
5: Subtitle (DVB), French
a02 The Nero decoder doesn't seem to work, will use libav instead.
a02 Extracting audio track number 2...
a02 Removing E-AC3 dialog normalization...
a02 Decoding with libav/ffmpeg...
a02 Remapping channels...
a02 Applying RAW/PCM delay...
a02 The AC3 encoder received a non-supported data format (float, 5, 64, -).
Aborted at file position 1048576.
Same thing for encoding directly from eac3 :
