eac3to – vielfältiger CLI-Konverter für moderne Audio-Formate

Es geschehen noch Wunder ... heute hat madshi tatsächlich eine lang erwartete neue Version herausgebracht, und wir wollen hoffen, dass es noch weitere geben wird.

eac3to v3.25 — http://madshi.net/eac3to.zip

• fixed: option "-down6" didn't handle 6.1 tracks properly
• fixed: option "-down6" for 7.1 content lowered side channels in volume
• fixed: 6.1 DTS/E-AC3 libav decoding resulted in incorrect 70f channel mask
• fixed: a couple of funny AC3 channel configs resulted in swapped channels
• fixed: option "-check" failed for SRT subtitles
• fixed: MKV tracks without language information didn't default to "English"
• fixed: 16bit MLP decoding didn't work at all
• fixed: DTS 2.1 decoding had empty sub channel when using ArcSoft decoder
• fixed: muxing h264 video streams without VUI eventually crashed
• fixed: SMPTE 302M 20bit PCM tracks didn't extract properly
• improved AC3 seamless branching handling by detection of identical frames
• improved DTS seamless branching handling by detection of identical frames
• updated to latest ffmpeg/libav revision
• added support for libav DTS 6.1 and 7.1 decoding (only in core, no DTS-HD)
• added support for encoding all AC3 channel configurations
• added support for demuxing Blu-Ray primary E-AC3 tracks (AC3 core)
• libav is now the default decoder for AC3 and E-AC3
• option "-down2" is now deprecated, but still supported
• option "-downDpl" mixes down to Dolby Pro Logic II
• option "-downStereo" mixes down to standard stereo
• added support for mixing any channel configuration to stereo/DPL
• DPL downmixing doesn't lower volume, anymore (except when clipping occurs)
• editing audio tracks by adding silence is now less restrictive
• trying to mux right eye stream to MKV errors out now, instead of crashing
• doing "eac3to 1) movie.mkv" for 3D BDs now properly skips right eye stream
• FLAC encoding is now done with optimized block sizes for "LossyWAV" files
• encoder bitdepth for lossy DTS tracks is no longer displayed
• option "-test" no longer checks mkvtoolnix

Überraschung:

eac3to v3.28 released

http://madshi.net/eac3to.zip

Code

* fixed: #001: different number of frames for left and right eye
* fixed: #061: valid silence edit was sometimes rejected
* fixed: #067: error messages were not available to GUIs
* fixed: #086: left/right eye information was inverted in some 3D Blu-Rays
* fixed: #131: TrueHD Atmos streams could not be demuxed or decoded
* fixed: #243: ArcSoft DTS decoder crash made eac3to crash, too
* downStereo: added 0.7071 factor for surround/back channels (ITU-R BS.775-3)
* downStereo/Dpl: using 0.5 instead of 0.7071 factor for LFE (ITU-R BS.775-3)

Please note that some of these changes have been implemented without a lot of testing. So it would be great if you guys could double check things, especially the changes, to make sure they really work as intended. Also please make sure TrueHD decoding still works losslessly, as usual (even for non-Atmos tracks). I've hacked Atmos "support" into the old ffmpeg version I've been using for years, so I wouldn't have to update to the latest ffmpeg version. Don't have much time atm, so I tried to do the most important stuff with the least amount of work.
