Ripping The Pasific - stops playback after 16 minutes

[wirrum]

Hi all!

I've just bought my license for MakeMKV, and was ripping my first blueray (I've only tested it for playback earlier). It was the tv series "The Pasific". There are 4 episodes on the disk, and I ripped it using the command line took makemkvcon on linux. The ripping went just fine - no error messages.

However, when I was testing the finished mkv files, they played just perfect for about 16 minutes. Then the playback stopped, as if the end of the movie was reached. I tried playback both with xbmc on linux and VLC on my mac, with the exact same result. The progressbar indicates that the file should be about 55 minutes (give or take), but it only goes about a quarter in (16 something minutes) before it just stops.

This happens with both episode 1 and 2 (I haven't tested 3 and 4).

Any idea why this happens (and preferable what, if anything, can be done)?

Hi.

As I've read through some forum posts, I saw a tips about mkvmerge, and decided to give it a shot. And also mkvmerge aborts with an error. The resulting file is 4Gb, and the original is 13. So this is possibly on the same place that xbmc/vlc runs into problems. Attached is the output from mkvmerge.

Hi!

The resulting file is 4Gb, and the original is 13

Sounds like your hard drive is formatted as "FAT32", which limits INDIVIDUAL filesize to 4Gigs.

Working with Blu-ray files requires an "NTFS"-formatted hard drive (has no 4Gig limitation) - preferably with at least 100Gigs of free space...

The filesystem is ext4, so it should be able to hold bigger files. There has been no problems with other larger than 4gb files before.

It is in the same filesystem as the original 13gb file it is supposed to convert. So I believe the 4gb limit is just a coincident and not a filesystem limit.

I have two computers, both running ubuntu. One is my mediacenter (xbmc) and the other is my file server.

When I rip, I rip using my mediacenter, saving the file on the server, through a samba share (there is not enough room on the local disk on the media center to hold the mkv file).

When I playback other large files from my network share, like DVD and blueray ISOs, the whole movie plays just fine. No problem.

When I use MakeMKV to stream the media directly from the blueray disk, I am able to play the whole episode with no problem.

I will test with other blueray movies and see if they works. I don't think my playback problems are due to my samba share/file system. I believe the problem is caused by makeMKV. I have also recently updated to makeMKV 1.6.10, which might have solved the problem. Unfortunately I no longer have the first Pasific disk, as I watched it directly from the disk and then returned it. I will test with disk2, when I get it.

Thanks for your effort and suggestions so far.

I've now tried with other blueray movies, and they work fine. I also got my hands on the pasific series again, with the same result as before. Playback stops after 15 minutes. If I use makemkv to stream the disk directly, I'm able to watche the whole episode (around 50 minutes). But if I choose to create an mkv of it, playback stops after about 15...

I figured this out, finally. As one of the posts above suggest, this is indeed caused by the samba file system. I've now shared the same directory as nfs, and the same movie backed up to nfs plays back flawless, whereas the version backed up to the same directory shared with samba stops after about 15 minutes.

makemkv does not give an error, and the files are the same size on the file system. Both files are played back through samba, so it does't seem to be a size constraint in the samba protocol itself (the playback is through xbmc build in samba, where as saving is done via a linux samba share mount).

So in short, it seems to be a good idea to not backup to a samba share. You wont get any error messages, but when it's playback time you will not be able to finish your popcorn due to premature movie ending.
