@DoctorM

Are you playing end-to-end or jumping around and looking at the frames? ffpmegsource2 isn't frame-accurate when an M2TS is a source. From the ffmpegsource2 user manual:

Still, I don't know the algorithm used... and DVD RB's method always seemed damn good so I'm willing to assume it's still the best possible system.

@jdobbs - I'm a bit concerned about something though. Doing some further playing around with a BD25 to BD5 one pass CRF, I decided I wanted to compare source vs encode for quality.

Code:
source=ffmpegsource2("(Source)\BDMV\STREAM\00000.m2ts").subtitle("Source")
encode=ffmpegsource2("(BDRB Encode)\BDMV\STREAM\00000.m2ts").subtitle("Encode")
interleave(source,encode)
Just a few hundred frames in they go out of sync by a couple frames and then it moves back and forth throughout. No more than a few frames, but I'm at a loss to figure out why. ffms2 should be frame accurate and DVDRB encoding with directshowsource should be perfect since it is being encoded linearly. I'm not sure if I should be worried or not about this, but I've never seen that with encodings before. Any thoughts on this?
In what program do you load the avs script? I would like to make some quality check also but with MPEG-4 sources to know which CRF value fits best to my need.

My current script is:

LoadPlugin("E:\Users\X\Downloads\dgavcdec109\DGAVCDecode.dll")
a = DirectShowSource("L:\BD-50\THE DARK KNIGHT RISES\DISC1\DARK_KNIGHT_RISES\BDMV\STREAM\00020.m2ts")
b = DirectShowSource("F:\BDMV\STREAM\00000.m2ts")
Interleave(a,b)

That's probably it. Will extract the video and try again.

@mparade - directshowsource is definitely not frame accurate. You will need to index the files before you can do this. Demux the video streams and use either ffmpegsource2 or DGAVCIndex.

For viewing, I'm a throwback and still use VirtualDubMod. It still works so I've never felt a reason to change.

Thank you for the help. Anyway, I have been still using VirtualdubMod as well since the beginning of the release of DVD-RB.

First off, thank-you for making such a useful product. I donated to and used the original DVD Rebuilder product and I have donated to and use the BD Rebuilder product.
I apologize if this has been reported before. I did a search on this thread and did not see the issue come up.
I have been backing up the holiday DVDs and ran across some strange behavior in The Wolverine, NTSC, Movie-only backup, Keep HD soundtrack, all English subtitles, all English soundtracks, BD. The forced subtitles in the film do not automatically clear off the screen. To get them to clear, I had to fast forward. Otherwise the last subtitle would stay up.

FYI:
I have run inspect.exe and all items check out OK.
- Windows Version: 6.1 [7601]
- AVISYNTH Version: [2.5.8.0], Ok
- HAALI Splitter: [1.9.42.1], Ok
- FFDSHOW: [3326], Ok
- WIN7 preferred AVC CODEC: Ok
- WIN7 preferred VC-1 CODEC: Ok
- WIN7 preferred MPEG2 CODEC: Ok
- FFDSHOW VC-1 set to "wmv9", Ok
- FFDSHOW MPEG2 set to "libavcodec": Ok
- FFDSHOW AVC set to "libavcodec": Ok
- AnyDVD settings check: Ok.
- BD Rebuilder v0.45.0.5, Ok
- X264: Ok
- AFTEN: Ok
- FAAC: Ok
- WAVI: Ok
- TSMUXER: Ok

Windows 7.0, 64 Bit Home premium up-to-date

I was working on a series of backups so I did not get a log file.

Thanks for your help, and as I said before, my apologies if you were already aware of this.

Encoder settings, automatic, this is the vanilla version of the BDREBUILDER.ZIP.

Setup changes:
unchecked "Limit to one track for each language" for both audio and subtitles
checked "Keep HD Audio for BD25/Alternate intact"
All other setup is the vanilla setup.
Movie-only mode

Hmm... Interesting. I recently had an instance like this. And it may well have been on "The Wolverine" (can't remember exactly). Could be a bug in the original subtitle stream, I suppose.

I just did a movie-only backup of Wolverine two days ago... but I was reencoding the soundtrack to AC3. I run it again keeping the HD audio and see what happens.

Demuxed the video tracks with tsMuxerGUI, indexed with DGAVCIndex, modified the script and bing the frames line up perfectly. Whew.
Sorry for stupidly freaking out. Everyone always crow about how great ffmpegsource is, but not it's failures like issues with transport streams.

The final encoding from an animated film, 19gb down to 4gb, BDRB made a pristine copy. I'm hard pressed to find any differences randomly checking frames. Great stuff.

After all, it is so hard to parse a transport stream.

Call it the dark side of open source software.

Sorry if this has been answered before, but what is your current opinion regarding ffdshow vs. LAV filters?

So far I have been using the recommended versions of ffdshow and Haali from the first post of this thread without any issues. But recently I ran into troubles decoding source files with a non-mod4 width, and switching from ffdshow to LAV filters solved all these problems.

Since ffdshow is not developped any more, and Haali does not support some current formats, is it safe to ditch ffdshow and Haali and use the current (0.59.1) version of LAV filters instead?



Cheers

The last build I see of ffdshow was December 3rd (rev 4527). I don't know what you're following.

What am I following???

The last official and recommended version of ffdshow on sourceforge is from 2013-01-06 - ffdshow 1.3.4500

The version jdobbs endorses is ffdshow_rev4504_20130312_clsid.exe from March 2013.

And here is a recent quote from qyot27:
Quote:
ffdshow's development has almost halted, and on top of that, it relies on an internal copy of the libav* libraries, whereas LAV Filters doesn't. So basically, LAV is actively maintained and uses much more up-to-date versions of avcodec, avformat, etc. It's also capable of playing both HEVC and Opus - ffdshow can't (and unless there's been a recent update, Haali can't deal with Opus streams in MKV, despite Opus-in-MKV being finalized back in July).

It's been a while, but if I recall correctly the LAV filters have difficulty with VC-1 interlaced content. I'll give it a test later today and let you know if that is still the case.

So your quote regarding ffdshow's development is from a programmer of LAV filters. I'd take that with a grain of salt.

I'm not looking to start a fight, but BD RB already works. Have you found a bug with BD RB and ffdshow that you are reporting or are you just voicing your preference for your favorite filter? Do you have HEVC and Opus BD that need re-encoding?

Well at least on the VC-1 interlaced source I tested today it appear X264's LAVF function is now decoding it properly. I'll do some more testing.

Right now, though, if LAVF is selected and BD-RB encounters a VC-1 interlaced source BD-RB reverts to DirectshowSource() for frame serving. The same happens when there is resizing or other AVISYNTH filter requirements based upon settings.

If my continued testing confirms what this one source suggests, I may have to change the process flow. X264 has some internal filtering capabilities (like resizing) so I may be able to make LAVF work in more scenarios than now. Assuming all is well, it may even be worth consideration to make LAVF the default at some point.

Never mind, I had installed the x64 version of SupTitle

Once I installed the x86 files, it seems to be chugging along just fine.

My bad.

Thanks anyway!

Confused about "AVCHD"

I was fiddling with my "Mud" BD today and noticed that the .meta file for my BD-9 Movie-Only mux was set for MUXOPT --avchd. This surprised me as I don't have "Strict AVCHD for BD-5/9 Movie Only" checked and the .INI file has AVCHD=0.

Is this normal or did I find a bug of some sort? I don't think I've ever tried a BD-9 before with BD-RB, and the several BD-25s I've done of course are all muxed as Blu-ray.
