Problem splitting mkv files

[Sennaista]

Hi,

I'm using mkvtoolnix to split large mkv files in order to play them on my Yamaha BD-S667 player via USB. The original files are h264, full HD and 24 fps. I have also disable "header removal compression" in the Options. The split files play nicely on my PC (Linux, BTW) but when transferred to the USB stick and played on the blu-ray player the video is corrupted.

Any ideas what could be causing the corruption?

Thanks in advance.

Well, I don't know if this is the same thing but I recently had some trouble splitting .mkv movie files. I wanted to split sections of a movie and just have those sections as one piece. The result was that some parts of the movie I split came out OK and some of them came out with bad sound synch problems. I then went back and used AVS Video Editor and decided to just trim out each section one at a time. I don't know if I needed to do it like that or not but I just thought that doing one section at a time might work better. The result was that every section came out in perfect sound synch. Then I just recombined all of them in AVS Video Remaker which took like 5 minutes for a total of 28 minutes of film. Love that Remaker.

In your case, I think I might try to convert your movie to a different format. It could be that your blu-ray player just doesn't like the format.

Maybe the original files doesn't play either? Or have you tried them?

Post the details from the mkv. Use Mediainfo, view->text and copy all details.

I carried out some more comparisons. I have a few shortish 720p mkv files that can be put on a USB without splitting. Some of these play nicely, some don't. Here are the outputs from mkvinfo for them.

This file works perfectly on the blu-ray player:

This one doesn't and the video is corrupted, or "blocky":

I'm afraid I can't play the original 1080p files I'm trying to split as I have no means of transferring them. Have ordered some DL DVDs so I can write them in whole as data and play them on the blu-ray player and see what happens.

[tkmbe]

Did you solve your problem?
I have similar problems. Almost all mkv I have does not play on my philips TV over dlna server.
But a few files does play. What I noticed is that in my case and yours the option
Codec decode all: 1

in the tracks of the file which works is set but I have not found how to set this option with mkvmerge
Any idea how to set?
BTW: The same files on hd read over usb works fine for video but no sound ...

[tkmbe]

Have just found more info.
The files which works must be written with mkvmerge < v3.4.0 (i.e. 3.3.0 ok, 3.4.0 bad)
There are several problems.
1. Philips does not recognize the mkv file if mkvmerge is > v3.4.0 (the header seems to have changed and will no be a valid file)
No idea how it checks that with dnla but it checks!
2. If application is < v3.4.0 it is playable only if the option Codec decode all: 1
and if no compression is used (the well known firmware bug on almost every first implementation of mkv support)

I have to get an old mkvmerge to confirm this ...

[blud7]

If your player can handle it, format your USB stick as NTFS.
This will allow you to copy larger files to it, no splitting necessary.
Unless I misread your problem

@tkmbe try disabling header compression. Several players fail to
recognize mkv with it enabled. The setting can be accessed from mkvmerge.

[tkmbe]

Yes I can confirm that the problem are the libraries libmatroska>=1.0.0 and libebml>=1.0.0
It was really tricky to build the stuff because old versions do not compile on new linux distros on opensuse.
Had to use a VirtualBox instance of debian 6.0 to compile my own version.
So you have to use and old mkvtoolnix which use this old libraries or have to built like me you own version on an old system
to convert movies but I think the most people will use windows not like me

Happy convert

Enable the "Disable Header Removal Compression..." option:

Exit MMG then restart it for the change to take effect. Then remux/split your file.
