    You won't hear anything about Codec Packs from me, in the past I had to completely reinstall Windows just one too many times using the K-Lite or CCC packages.

    For AVStoDVD it is important that the Preferred DirectShow Filters are set to LAVFilters or maybe to ffdshow. Anything else means trouble. I am still curious why your uploaded sample does not work on your machine. Please post the A2D log file for such a failed conversion.

    I don't think seeker47 uploaded a sample nor a log, did he? I uploaded the SD sample myself at your earlier request,
    and my issue was solved with the 2016 ffms2.dll. His problem would presumably be solved by the same method

    Sorry, I mixed it up somehow...
    But again, without a sample and a log file it is hard to give any assistance

    I brought this issue up in the Doom9 thread about the ffms2 C_Pluginn:
    https://forum.doom9.org/showthread.php?p=1868785#post1868785

    It looks like indeed for high bitdepth sources the older ffms2 version ffms2_r1140+101-avs+vsp.7z from 2016 is the only version which works.

    It was just the MediaInfo report that I posted. I would try to post the other two, but can't get to that until sometime next week. Before then, I'll need to figure out what to use to extract a clip, seeing as Machete won't even load the file, for the reason I mentioned.

    Why don't you just install the earlier version of ffms2.dll that has been discussed here and see if it works?

    And from where can I obtain that older version of this DLL ?

    Thanks manolito. I'll give this a try and report back.

    Swapped in that earlier version DLL, and I was able to run that previously mentioned job (with that HEVC source) to a satisfactory completion, replete with the extended ASCII subs that had drawn a complaint, but which came out looking normal to me. (This was still making use of the installed version 287, which I've not updated yet.) However, this time I went with FFMPEG CBR 1-pass for the video, rather than the HCenc 2-pass VBR -- which had failed on the earlier attempt. I may do another run that way, with the replaced DLL, to see if anything changes there. Assuming that works, it remains to be seen whether there is any noticeable PQ advantage from the use of the HC 2-pass, vs. the standard FFMPEG encoding.

    [Update: the choice of using HCenc still fails in the exact same way as I mentioned in post #3766. And isn't the most recent version of HC being used in AVS ? Now wondering if latest AVS version might make any difference ? Probably have to keep that older DLL though.]

    If your source video is high bitdepth (12bit or 10bit) then you will always need this older ffms2.dll. The reason is that all newer ffms2 versions will output the same bitdepth as the source by default, and the DVD format needs 8bit. Newer ffms2 versions need the additional parameter colorspace="YV12" for ffvideosource to work in AVStoDVD.

    You can add this parameter in A2D by editing A2DSource.avsi and/or manually add the parameter under "View/Edit Title", but most users will not like to do this. I already requested a fix for the next A2D version, but you know that MrC does not have a lot of time these days for maintaining the software...


    If you can see a difference in quality between FFmpeg CBR and HCenc 2-pass VBR depends on the video bitrate. FFmpeg CBR only produces high quality at very high bitrates. And yes, A2D uses the latest HCenc version from December 2015 (which will most likely be the last version).

    FWIW you might want to bookmark this link:
    https://forum.doom9.org/showthread.php?p=1814958#post1814958
    Here you can find all the necessary information for updating the A2D helper software, and I try to keep this post up to date as good as I can...

    I asked qyot27 (he builds the ffms2 C-plugins) what I am missing when I stick with the older DLL, and the most important new feature of the current version is support for AV1 video sources. This format is still in its infancy, but it has the potential to become important, so a source filter should support it.

    AVStoDVD works fine with the latest version of ffms2, but for high bitdepth sources the colorspace="YV12" parameter must be added to the ffvideosource commandline. I tried to add this feature to my FF_VBR and HCenc_Mod plugins, and for the encode this works fine. The problem is the preview, because I have no way to modify the separate AviSynthP.avs file automatically.

    Let's hope that MrC will find some time to add the colorspace parameter to AVStoDVD. If someone is interested to try my updated plugins, let me know...


    Cheers

    I would mention, especially if MrC is considering some changes, this little quirk and whether it can be handled better:
    If your source is video only - no audio, the program still allows you to choose "muxed mpeg" as your output.
    Then when you run it, it fails when it realizes the audio is not found

    The old TmpgEnc from 15 years ago was able to save a program stream (.mpg) containing video only,
    so it must be legal

    The error you get is not an Mplex error, it is AVStoDVD itself which catches user errors wanting to protect users from doing stupid things...

    Multiplexing means combining video and audio elementary streams into a new stream where the elementary streams are interleaved. So when decoding this muxed file a splitter can take the original streams apart and direct them to the proper rendering software.

    In your case when there is only one video elementary stream there is nothing to multiplex. Just specifying to create elementary streams and then renaming the .m2v file to .mpg is probably all you will need. It may not be technically correct, but so far all my software could handle such files.

    If you want to do it 100% correctly then you can use Mplex to create an MPG file from your M2V. I made an MPLEX droplet some time ago where you can drag and drop or copy and paste your source streams on the executable, and you will end up with a muxed MPG file. The droplet does not do any error handling by itself, so if you just drop a video elementary stream on it it will happily mux it into an MPG file.

    Cheers

    I understand. Then perhaps it would be better for A2D not to allow you to select that option from the output choices when there is no audio ...

    Either this or disable its error handling for multiplexing.
