Forget about buggy ffvideosource. Use lsmash.
What's the biggest issue right now? FFVideoSource is still the default in staxrip.

Ffvideosource is not frame accurate for example

What's the most common scenario where frame accuracy is needed?

I don't want to keep all the subtitles. Is there a workaround or a fix for this issue?
I get that message all the time
Use MKV Merge and reduce subtitles <30

When you use a lot of Trim function. for example Trim(100,200)+Trim(300,400)+Trim(600,700)

It only occurs if RipBot264 demuxes from a ripped 4K disc. If I use MakeMKV to make a mkv of the 4K source, and then pull that into RipBot264, everything behaves normally and takes seconds to complete. Only extra bit is for the EncodingClient to copy the large mkv before starting. So at least that is a workaround for now.
Atak, have you had time to look at this and see if it is a bug or something unique to me? If it is a bug and you're working on it, I'll leave my 15 or so 4K jobs there to hopefully have a fix soon. If your cannot confirm it or don't have time to look at it, let me know and I'll start converting those disc rips to mkv files, delete and re-add them to RB. Thanks much.

I do not have access to 4k BD at all...
However I would like to compare lsmash indexes (.lwi files) for mkv created by makemkv and ripbot.

BTW, detecting boarders took seconds from the MakeMKV 4K compared to 10-20 minutes from the demuxed version.

What happens if you take that video.mkv from job folder and mux with mkvtoolnix to new mkv? Does it also cause the same problem?

Curious about SeekTester, is this why you index the files and pull them apart prior to compression and then remux them?

I have an alternate cluster encoding program I've been working on for Linux with a friend and we don't pull files apart or reindex them as you do but it passes your test program so I'm curious. This program is a ways from being mature enough to release and cannot presently use filters the way RipBot does but it does build pieces of files across many computers and then combine them so it's not completely different. The added steps have always been confusing to me for this reason

I muxed the RB extracted video.mkv along with all the contents except the video from the Casino Royal MakeMKV mkv and made a new mkv which I imported into RipBot. Everything was still speedy with the new mkv.

Did the index files look the same?

Something just clicked when you said this and showed the image with errors. When you say frame accurate you don't mean timing, but rather frames completely just get skipped when they are not "accurate"?
I haven't played with GPU decoding much but if that is more accurate than LSmash I'd even use that on the machines I can use it on.

I solved it by this way.
But if the recomendation is to use lsmash instead of FFMS2 there is still an issue corresponding with ...video.mkv.ffindex_track00.kf.txt which seems not to get created.

Are you sure you have latest version? Other people do not report this issue.
Btw. I'm using lsmash all the time. Ffms2 is dead for me.

Seektester Has nothing to do with de mode. Frame accurate seeking is crucial in De mode so i wrote that tool to establish which source filter is the most reliable. Lsmash is super stable while ffms2 is not.

No they are different because video.mkv is just a raw .265. eac3to can only demux hevc streams. For some unknown reason lsmash has problem with raw hevc. Could you upload first 5GB of video.mkv. Use dgsplit. Do not use mkvtoolnix. I would like to see If i also get that huge delay.

Though, there might be at least one other thing going on. When I have a 4K source, I select two audio tracks. Most of the time the first track is a AC3 core from a TrueHD track, and the second track is a demux of the same TrueHD track. After the job has been created and I click to add the second track, the Gathering Information takes about 10-20 minutes. The MakeMKV job takes about 30-60 seconds.

Ok. So the problem may not be related with HEVC stream but with TRUE-HD. Interesting...
BTW. can you check if .lwi file for true-hd is already created in job folder before you select second audio (True-hd)

I made a new job and it did make a .lwi file for the TrueHD stream. Is it normal that the .lwi for TrueHD will be 400MB in size? The TrueHD stream itself is 2100MB. The video .lwi file is only 14MB in size.

While pulling in the job, and it is saying "Gathering Information..." for 10-20 minutes, ffprobe is running during this time. Then "Extracting Frame..." takes another 5-10 minutes.

Yes it is "normal". It was even worse in previous version of lsmash
https://forum.doom9.org/showthread.p...25#post1889725

Can you send me whole True-hd stream? The longest sample I currently have is only 10min long?
