tsMuxeR giving "Reading buffer overflow" error at 47.4%.

[hbenthow]

I'm using tsMuxeR to mux an m2ts file from the STREAM folder of a Blu-ray folder I authored with BD-Rebuilder into another Blu-ray folder. I'm doing this because BD-Rebuilder gives me no control over the subtitles. I BD-Rebuilder to author the Blu-ray from non-Blu-ray compliant files, then use tsMuxeR to create the final Blu-ray with the subtitle size, offset, etc, adjusted to my liking. I've already done with multiple times, without a hitch.

But now, with my latest Blu-ray project, tsMuxeR always stops at 47.4% and gives the following error:

Reading buffer overflow. Possible container streams are not syncronized. Please, verify stream fps

I've never had this problem before, and have no idea how to fix it.

Maybe try an older version of tsmuxer?

Or try use something else instead of bdrebuilder like bdtoavchd. I think you can add subtitles directly in it.

[fritzi93]

Try Clown_BD (an eac3to front end).

I've seen that a couple of times. I can't say for certain, but I suspect an issue with DTS-MA (and I have the Arcsoft DTS decoder). On those problematic discs, the Clown_BD log listed something like "sync byte discontinuity" or "sync byte missing", but eac3to has always been able to fix it.

Then use tsMuxer. Worth a shot anyway, and if that doesn't fix it, you can be fairly sure you've eliminated audio as a possible issue. Good luck.

Non compliant files may cause that error in tsmuxer. This is especially true if you ever had the file as a MKV with TrueHD audio. Muxing it as a MKV will strip the ac3 core from the TrueHD. tsmuxer expects the core to be part of the TrueHD to be Blu-ray compliant and it will fail. Thats why its a bad idea to use MKV if you ever want to remux back to Blu-ray.

If nothing else works, I might have to try that. I can't do the re-encoding on just any day, since it takes so much of my computer's resources that I have to plan ahead.

I'm trying Clown-BD right now. I'll report back with the results.

I don't think you understand what I've been doing. Here's how I do it, step by step:

1. Take a non-compliant (due to aspect ratio) HD video file (usually MKV) and convert it into a Blu-ray folder with BD-Rebuilder. This fully converts the video so that it is Blu-ray compliant.

2. Use tsMuxer to convert the m2ts file in the STREAM folder of the Blu-ray folder created by BD-Rebuilder into a second Blu-ray, using the tsMuxer settings to adjust the subtitles (which I import separately into tsMuxeR as an SRT. file) and the chapters to my liking.

Well, I used Clown-BD, then ran the resulting file through tsMuxeR. I got the exact same result. It stopped at 47.4% and gave me the exact same error as before.

I'm not saying you're wrong as I don't know one way or another, but since you're making this claim, do you happen to know why some MKV muxing program would just strip out the AC3 core? WTH? If I tell a program that creates MKV that I want to mux audio A and video B I mean that I want audio A and video B as they are, not audio A minus some stuff that they think I don't need. There's no reason for the core file to be removed and without it, I'm not sure if the remaining audio can even be decoded correctly. So WTH is going on here?

Did you resolve the problem?

When you say "non Blu-Ray compliant files", that could mean any number of things. Anyway, as per the error message, did you verify the fps in tsMuxer? Click on the video stream and look at the fps. It's possible tsMuxer isn't detecting it correctly and it needs to be changed. If the original was, say, a buggered (incompetently encoded, cropped) downloaded MKV, you might need to change fps, most likely to 24000/1001 (23.976).

No.

1080p MKV files with non-Blu-ray compliant aspect ratios like 1920 x 804. I use BD-Rebuilder to convert them into a Blu-ray folder with the correct aspect ratio (1920 x 1080).

tsMuxeR says 24000/1001. I also checked the m2ts file with MediaInfo, and it says 23.976 fps.

[hbenthow]

Well, I converted the MKV to a Blu-ray folder again, this time using AVCHDCoder. When I ran the new m2ts file through tsMuxeR, I got the same error, except that it was at 47.3% instead of 47.4.

[fritzi93]

Does the process complete in tsMuxer if you leave out the subs? If so, that would suggest a problem with the subs, obviously.

If not, are you willing to try Clown_BD again? This time have it extract the core or re-encode the audio to 640 kbps AC3. I'm still not convinced the problem does not lie in the audio.

Good luck.

[johns0]

Easiest way to see if the audio is the issue is to remux the m2ts through tsmuxer and uncheck the audio before muxing.
