I think it works best if you convert to W64 then WAV with FFMPEG.
ffdcaenc doesn't like WAV files from eac3to: Code:
eac3to input.dts intermediate.w64 Code:
ffmpeg intermediate.w64 -acodec pcm_s24le proper-lavf.wav Code:
ffdcaenc proper-lavf.wav -o final.dts -b 754.5 -l That's how I have to do it before it can work for DVD(-9) convesions. Using just eac3to will create broken WAVs that ffdcaenc won't complete. With FFMPEG including dcadec in all recent builds, maybe it should work out the same if you leave out eac3to and start with ffmpeg directly. Code:
ffmpeg input.dts -acodec pcm_s24le proper-lavf.wav

I'm using ffdcaenc from http://forum.doom9.org/showthread.ph...50#post1688150 (windows users) and work without problems with:
eac3to input.dts stdout.wav -down6 -dcadec | ffdcaenc -i - -o output.dts -l -b 754.5 -down6 necesary for DTS-MA 7.1. Ignored for other sources. -dcadec recommended. Now only is the default for DTS-MA 7.1 @Sparktank What is your problem with "ffdcaenc doesn't like WAV files from eac3to"? ffmpeg output the same format with -acodec pcm_s24le than eac3to, a wav 24 bit with WAVE_FORMAT_EXTENSIBLE header.

I can't remember exactly, but I remember having to do longer footwork to get it to work for me. Version I used was same as Mulder provided in linked post. I think in rare cases, for longer movies, it provided >4GB WAV which didn't work correctly for me. I'll try replicate scenario.

-l Ignore input length, can be useful when reading from stdin must solve the problem with wav >4GB. BTW using ffmpeg you have the same problem until ffdcaenc don't support w64 input.

Assuming the source is 7.1 or 5.1,
and unless you have little storage space OR intend to do some DVD-video authoring, I see no good reason for choosing that bitrate... Depending on the source (and on your ears as well, of course), any value between 960kbps and 1344kbps should be more adequate than 754.5kbps, for 48kHz-sampled material. |

Hm.
There was so many builds available in the ffdcaenc thread, but the one I'm using now: " ffdcaenc-213_GCC_20140801 " And it accepts >4GB WAV from eac3to. No need to use FFMPEG to re-create WAV file. I'm not sure what version it used to be, but somewhere, >4GB WAV wouldn't work at all so I had to resort to W64 first and then create a WAV file with FFMPEG that was >4GB. Options like -l didn't matter at the then time. Not sure what the situation was then, but now it's fixed. FFMPEG not needed. (W64 to WAV) Code:
eac3to v3.29 command line: eac3to "ManofSteel.flac" ManofSteel.wav -down6 ------------------------------------------------------------------------------ FLAC, 7.1 channels, 2:23:04, 24 bits, 4689kbps, 48kHz Decoding FLAC... Mixing surround channels... Writing WAV... Creating file "ManofSteel.wav"... The original audio track has a constant bit depth of 24 bits. The processed audio track has a constant bit depth of 24 bits. Caution: The WAV file is bigger than 4GB. <WARNING> Some WAV readers might not be able to handle this file correctly. <WARNING> eac3to processing took 5 minutes, 16 seconds. Done. Code:
C:\Apps\Audio\ffdcaenc_213\ffdcaenc.exe -i ManofSteel.wav -o ManofSteel[754].dts -b 754.5 -l

I was doing a DTS encoding test with filler56789's version, since the "official" version crashes under XP-SP3. I set the bitrate to 1536 (5.1). When I tried to play it with VLC, over the SP/PDIF optical cable, the amp did not see it as DTS. After a few minutes that amp finally displayed DTS, but there was still silence.
I put the file in my NAS and played it over the HDMI connection and all was fine. Any ideas as to what could be wrong? Even if I figure out what is wrong, I'll probably stick with AC3-5.1, as DTS5.1 is about 3x the size of AC3-5.1. |

Any bitrate for dts are legal, but to use spdif or for build DVD/BD is recommended only 2 bitrates (like is show in help files).
With ffdcaenc: To obtain a standard DTS 1536 (Transmission bitrate) you must use a real bitrate of 1509.75 To obtain a standard DTS 768 (Transmission bitrate) you must use a real bitrate of 754.5
