@manolito Wow! That 2 Pass with HCencVBR you suggested is right on the money! I knew that something had to give because when I use DVD-RB Pro, it uses the HCenc and the results are immaculate. Thanks again. I'll maybe take a look at that Tiny player just for kicks. For the preview to work natively from the app, ffdshow has to be installed, otherwise you have to set it to use an external player.

it also seems DTS source audio tracks need to be 20bit or lower to be direct copied by avs2dvd, this apparently is a muxman problem ? , id guess Blu-ray source files are 24bit DTS audio, as is your MKV so will need re encoding as quoted by Mrc, Many (I would say all) 24bit DTS tracks are refused by muxman. Sometimes it refuses 20bit tracks as well... hence the DTS compliance is not 100% solved. (wheter this is still relevant im not sure) so I guess your options are, AC-3, or find a way of re encoding your DTS audio tracks to 20bit and hopfully avs2dvd will direct copy, and hopefully muxman will accept it and do you really need DTS on a DVD ???, AC-3 is almost on par on a Blu ray, yes I understand, superior picture and audio DTS-HD and master, im guessing DTS will take up more space leaving a lot less space for the video on a dvd ?, considering your compressing video from a already compressed video at only 3 gig to start with for 1hr+ of footage the sorce is prob not the best to start with Last edited by Mike-uk; 15th March 2020 at 13:22. |

Totally agreed...
Also keep in mind that DTS audio is not a mandatory format for DVDs, it is only optional. There are tons of standalone DVD players out there without a built-in DTS decoder. A DVD with only a DTS audio track without also having one of the mandatory audio formats is NOT DVD compliant. |

Hi manolito I have a question. I've been getting the warning "A file with AAC (Advanced Audio Coding) audio stream has been added, and default audio codec is Microsoft DTV-DVD Audio decoder". I haven't changed anything with regards to my LAV filters so unless Windows did this on its own I have no idea where this is coming from. Anyway the DVD came out just fine. I did go and use the tool to have LAV filters as default. Should I change the Avisynth tab settings in preferences and set video and audio source filters to FFMpegSource? Thanks.

Are you using Win10?
The only reason I can think of that your DS Filter Settings change by itself is that Win10 updates change these filter settings back to the original Windows filters. If using the Microsoft DTV-DVD Audio decoder gives you good results (check for Audio/Video sync problems) then of course you can use these filters. Or rerun the Filter Tweaker tool after each Windows update. Ditching DirectShow altogether and using FFmpegSource as your source filters is an alternative. The only drawback is that the source files need to be indexed which can take some time for longer sources. |

Yes you were correct. It was an update after which the settings were changed. Everything's fine now. Thanks. Running the Filter Tweaker Tool doesn't automatically change everything to LAV Filters. You have to make the changes yourself for each item.

Guys, back in business... after some time I finally decided that 2.8.9 must have a final build. So... here you are a new alpha
AVStoDVD 289 Alpha 200925 @ SourceForge Cumulative changes log from release 2.8.8. Changes from latest alpha are marked with +. - Added support to PGS BluRay subtitles - Added handling and display of MediaInfo BitDepth video tag + Added support to 7 and 8 channels audio source (Downmix.avsi script file updated, thanks to Manolito) + Added Chapters section to Demux File tool - Improved Muxing routine: better errors handling and switch to FFmpeg (instead of Mplex) when no audio source is present - Improved usage of FFMS2: now YV12 colorspace is always specified (A2DSource external AviSynth function updated as well) - Improved AviSynth program info retrieving routine (now using AVSMeter) + Improved Seek Chapters routine (new "aggressive" mode added, original mode is now called "mild" mode) - LAV Filters updated to release 0.74.1 - AVSMeter updated to 2.6.5.1 (2.6.5 modded release to improve reading speed) + MediaInfo updated to release 18.05 Bye |

My pleasure...
Finished my tests with this new build, not much to report: A very very small correction to the German language file: Quote:
The addition of the new audio downmix functions works well. I noticed that you overhauled the menu highlight colors. Also no problems, the only thing is for folks who overinstall the new build over an older build will have to reselect the hightlight colors to get the colors they want. As usual I did not test the new subtitle features, this should be tested by users who actually use subs. My tests were under WinXP and Win7 - 64bit, Win10 users should make their own tests. There were reports by Win10 users that the preview did not work for them. I cannot reproduce this. Another Win10 related issue seems to be that Win10 updates can sometimes reset the preferred DS filters to the original MS DMO filters. If you intend to release a last and final stable version of AVStoDVD there are a couple of considerations how you could harden it for the future. The DVD specs are static, only new source file formats may cause problems. The source filters should handle new formats, the problem I see is with MediaInfo. The current MediaInfo versions do not work with A2D since Zenitram changed the output format. But even if you made A2D compatible with current MediaInfo versions (which would mean a lot of work) there could still be problems in the future. Right now there are already issues with multichannel audio. There are many different 8-ch audio formats, and MediaInfo reports very different output for the number of channels. Sometimes A2D interprets such MediaInfo output as 0 channels. The workaround is to play the source file with a DS based player and check the LAV audio status tab which reports the number of channels which LAV sees. Then the user can manually change the number of audio input channels in A2D. Of course Win10 updates are another threat for the future stability of A2D, but there is nothing you can do about it. Whatever, as far as I am concerned this new build is ready to go stable... Cheers manolito |

I almost forgot to mention a long standing issue when users specify to use an external player AND the default source filter is A2DSource...
(I stumbled upon this issue after recommending to use an external player to users who could not get the internal preview working.) When A2DSource is selected then the AviSynthP.avs script loads A2DSource.avsi from the "AVStoDVD\Lib" folder. But AviSynthP.avs is called while the active folder is "C:\Windows". This means that A2DSource.avsi is not executed correctly, so the external player will either not work at all, or there will be no audio. Including the Lib folder in the Path does not fix it. The current workaround is to use DirectShowSource or FFMS2 instead of A2DSource. To fix the issue completely AVStoDVD would need to make the Lib folder the active folder before calling the preview.

Hi MrC,
I found the post where I published my 8-ch audio findings: https://forum.doom9.org/showthread.p...90#post1893390 Unfortunately I did not keep my test clips, and demo-world.eu closed shop recently. But you could use AVSMeter instead of MediaInfo to retrieve the number of audio channels which the currently used source filter actually sees. No idea if this is feasible... For the external player issue I made more tests, this time including WinXP and Win7-64. Results: WMP and Tiny Player worked under both OS MPC-HC 32 gave this error: https://i.postimg.cc/HxC6bPHS/MPC-HC-32.png VirtualDub 1.6.19 did not find an audio decompressor: https://i.postimg.cc/nrS5KY3C/VDub-Error.png https://i.postimg.cc/0N5B4Bhb/VDub-Info.png For me especially VDub is an excellent replacement for the internal preview, because it allows me to do multiple cuts (editing out commercials), and with the help of a small utility called VCF2AVS the edit points can be translated into AviSynth Trim commands. And as I already mentioned the problems disappear when I use FFMS2 or DirectShowSource, so it must be related to the fact that A2DSource.avsi lies in a different folder so the plugins it tries to load do not load correctly. This happens only for the preview, the encoding is not affected. Cheers manolito //EDIT// Good news, I managed to solve the problems with the external players... For MPC-HC it was necessary to copy all the plugin DLLs from the "AVStoDVD\Lib" folder into the "AviSynth\plugins" folder. Easy enough, and I do not expect any adverse effects as long as the plugins in both folders are identical. For VDub I believe that my old version 1.6.19 was to blame. Upgrading to the latest VDub2 version solved it, and so far this VDub version seems to work nicely even on my ancient desktop computer. Last edited by manolito; 1st October 2020 at 18:20. |

Hi manolito, thanks for the double check with VirtualDub2 and MPC-HC.
Another oddity with MPC-HC is that anytime I feed it with a simple AVISource() script, it chokes (no render). Since AVISource is the first choice in A2DSource, that could be another reason of preview failure with MPC-HC. The AVSMeter workaround to grab audio channels works well. E.g. some dolby atmos tracks are read by MediaInfo as "15 objects / 6 channels". Very, very misleading. AVSMeter way or improved MediaInfo string parsing? Will do some testing. If you have any other exotic audio tracks, please advise. Bye |

For some 8-ch demo clips I found www.demolandia.net quite useful (too bad that demo-world.eu has closed down).

And I also managed to find the reason why my old VDub version could not decompress the audio when using it for the preview. This old version cannot handle 32-bit float audio... At some point in the A2D develoment you added the line global OPT_AllowFloatAudio = True at the beginning of A2DSource.avsi. This command is not present in the AVS script when a source filter like FFMpegSource or DirectShowSource is explicitly specified under preferences, so the old VDub will work. Only if A2DSource is used VDub will choke. Cheers manolito Last edited by manolito; 3rd October 2020 at 01:16. |

FWIW I found another method at StackOverflow for determining the number of audio channels. It uses FFProbe, this is the call:
