View Full Version : Known Issue: MKV Pass-Through

For some unknown reason, one of the tools (MP4box) used in the MKV pass-through conversion process crashes in the final moment of creating the playable MP4 video. This crash blocks the converter from performing any other operation until the crash error box is dismissed. This means that you must manually queue one of these files each time and you cannot queue more than one file.

Currently there is no fix for this issues and it’s quite possible that you will only be able to see 99% of your video after conversion. In most cases, this shouldn’t be a problem.

We will continue to look for new versions of the tool which will may stop this from happening and let you know if this issue is fixed.

I've tried the MKV Pass-Through on two different machines with no result. It says "Starting Conversion", then after a couple seconds goes to "Conversion Complete".
Am I missing something here?

Should I be installing MP4box seperately?

@ adamnikyo

Turn console on, so that you can see whats the problem with the encoding!!!
My console log said that i have not enough disk space so i resolved this problem, so see what is your problem.

@redkawa

With some movie i start processing and after it says "COMPLETE" there is no file in the output folder.

I had a mkv with 6 Channel ac3 Audio so the log says:

But when i extracted the mkv file manually and convert my ac3 audio to 2.1 with besweet and muxed it with mkvmerge the "MKV-Through" works without problems.

I hope i helped.:)

Strange. It has worked fine for me with the 2 mkv's I have used. No errors and the resulting MP4 video file plays right to the end! :) I havent had to queue anything up either.

UPDATE: I have noticed that it doesnt work with any of my files that are over 4GB. My tv episodes convert fine, my movies don't. They say they can't read the audio/video files in the console log. Damn! My tv episodes look sweet.. was hoping for similar success with movies. However, I appreciate that there will be many factors that contribute to a successful conversion!

Try to extract the file with MKVExtractGUI and then remux it with mkvmerge GUI
At MKVMerge GUI you must only put in 23.976 fps for the Video, so it would work correctly.

I am trying to convert an MKV file that I was able to watch as an mkv, but after its done (it does that crash thing at the end), I can watch it, but I only get sound (and a gigantic black video window).

Here is the log.

hey, i have used the mkv passthrough and have converted sample mkv's to h264 and they have worked perfectly, best results have been with the mkvpassthrough settings.

however...

it only takes a minute or so to convert a minute clip, but when i tried to convert an hour episode of planet earth it took over 10hours...doesnt seem right...is there something im doing wrong or is it just the way its supposed to be? Still havent played the planet earth video yet cos its still converting.

If i could do the mkv passthrough in a couple of mins this would be the most perfect software on the net.

ok worked out that problem and turns out i changed the mkv passthrough settings and made it encode...new problem...crashes when i do certain videos at the audio stage.

have converted all of heroes and planet earth fine, done a couple of movies but i have a few that extracts the video and audio fine but cant do anything after it...console says....

@ adamnikyo

Turn console on, so that you can see whats the problem with the encoding!!!
My console log said that i have not enough disk space so i resolved this problem, so see what is your problem.

Thanx for the tip because the same thing was happening to me. But now I have a new problem. I have more than enough space on my drive but PS3 Video 9 I guess uses C:\ as a default for the buffer. I installed PV9 on my D:\ and I have more than 30GB free for conversion of a 8GB 1080p file. But since I have a separate partition for my OS which is only 15GB (C:\) and it only has 4gb free i keep getting the error.

Is there anyway to force PV9 to use my D:\ for its buffer to process the file for an MKV passthrough??

If not are there any other suggestions for getting an MKV of a 1080p H264 AC3 file to play on my PS3 without re-encoding it into another format and possible quality loss?

hi there,

i have the following problem. I tried a mkv movie with the passthrough method and the mp4 file plays fine on my pc but xbox refuses to play it (incompatible format).

The converter shows me no error. Everything should be fine.

The sample mkv file from the same movie works on my xbox.

Could it be because of the file size?

May it help if i change from 5.1 to 4.1 with h264info or could there be any other problem i haven't recognized?

Anyone had the same problem that the sample mkv file plays fine and the movie itself processed exactly the same doesn't work?

I wasted about 6 hours yesterday :D

The problem seems to be in the encoding of the extracted ac3 files. If you look a bit higher up in the console, you should find this:

Anyone have any solution for this yet? I have googled a bit and can't find a way around it.

Your video source has 19 streams....

In my case, the MKV Pass-Through failed because the ac3 stream could not be converted to aac.

This is because ffmpeg believes the ac3 file to be a mp2 stream, and fails with the error "could not find codec parameters". This is the same error that therealwakka reported earlier in the thread.

By splitting the mkv and running ffmpeg manually, adding -f ac3 to force ffmpeg to see the file as an ac3 stream, the audio stream was converted properly.

Your video source has 19 streams....

Nope, sorry. Only 1 video and 1 audio stream. It's a tv ep capture. And I get the same error with all of them. So I guess the detection is wrong, but even if it isn't, perfp is probably right:

In my case, the MKV Pass-Through failed because the ac3 stream could not be converted to aac.

My thought exactly. The problem is that having to do anything manually kind of defeats the purpose of using this app in the first place.

Can you count???

Yes. I actually learned how to when I was only 2. But if you don't believe me I can always provide the sample clip. There IS only 1 video and 1 audio stream in there. Even MKVExtract only detects 2 streams total. The question is, can you be humble enough to accept that something might be wrong in the detection phase?

I had the same problem where some ac3 files would encode but some would not. However I found a solution that works all the time so far with mkv files from 100mb to 7.9gb with AC3 audio of any bit rate.

The current ffmpeg that comes with Video 9 is r9133. Thinking if I update this program it may work I tried all the newer versions with the same or worse results. Then I decided to roll back and tried several from this site until I tried r7906. Magic.

Just rename your old one and replace it with this exe. So far it's been working great. The files play fine on PS3, although sadly in stereo of course. Now only I could get something to convert DTS audio.
