mkv2vob: New App to Remux MKV x264/AC3 which play on PS3

[DiZzle.]

Hi there,

I'm new on this forum, i've already read a lot of threads on this forum to find a gui to convert and playback video files on my ps3, and this one works great for me. Thx!

One suggestion, changing avc level by using hexedit is a lot faster, maybe something for your app?

I tried this method first, using seek and put to modify the bytes without creating a duplicate .h264 file, but the resulting file did not play back on the ps3.
Changing it with h264info was the only way that worked.

How can you have video/audio at different rates and expect it to play in sync?

All this program does is demux and mux.
It doesnt fix your audio so its the same length as video.
It doesnt care about or change the framerate or recompress or touch the video/audo in any way.
If your streams arent to spec in the first place, the output wont be either.
Your invalid file may work on your pc but the ps3 is very fussy about what it will play.

so do you know why you can't fastforward/rewind? is it at all possible to fix the issue? other than that, it worked flawlessly.

I´m from Spain.

I download a .mkv, when demux to h.264 the video is 23.976fps and the audio (spanish) .ac3 is 25fps. Then when mux into a .vob the a/v is desincronized. In the .mkv is sincronized, but when demux the .mkv lost the a/v Synchronization.

Sorry for my bad english.

[3r1c]

because vob does not support different a/v rates.
if you can give me a sample i will see if i can fix it

3r1c, would you mind sharing the ffmpeg commands your tool internally runs?

I have a script on my linux box, which does the same but reencodes the audio to AAC. I would like to adapt it.

What I basically do is:

- "mkvmerge -i" to get the info which track is what (audio/video)
- "mkvextract"
- change h264 level to 4.1
- decode ac3 with a52dec
- reencode audio with neroaac
- mp4box everything

From the tools that are included I think i just need the ffmpeg call you make.

Thanks!

Fixed in v 1.2

[SeeMoreDigital]

Can anybody provide a "re-muxed" sample file yet?

Thank you for your interest, but again the a/v is desincronized .

It works for the sample file you gave me.

[hyperspaced]

Can you share with us the commands you use for demuxing & muxing? Especially for muxing back to VOB.

thanks.

Umm...

When I play the sample in the PS3, the video is more quickly than the audio.

My PS3 is PAL.

Make sure you are playing from the beginning of the file and you have the 2.0 firmware.

I do not have a PAL ps3 to try this on, but they should play it the same, if not its a bug in the ps3 itself.

In the first version the sample you gave me played the video back slower (at 23.976 instead of 25 fps) this was corrected in the 1.2 fix, after the fix it played correctly for me.

I just double checked it again with your sample and it does indeed play back properly.

If your streaming through tversity make sure in Settings/Transcoder is set to "Never", save and restart.
Tversity sometimes tries to transcode the vob if set to "only when needed", this must not happen.

Here is the vob file that played for me, converted from your sample.

ffmpeg -r 23.976 -f h264 -i video.h264 -f ac3 -i audio.ac3 -vcodec copy -acodec copy -f vob output.vob

[buzzqw]

the framerate is computed by analizing the media ... or not ?

Well done for being the first person to attempt this. I know of tons of people who would like to play .mkv on the ps3.

Unfortunately for me it doesn't work. Everything seems to go according to plan but the PS3 just tells me "no supported tracks" or something like that

[3r1c]

buzzqw: Framerate is got from mkvinfo.

glen8: No supported tracks sounds like you dont have the latest firmware 2.0. Renaming .vob to .mpg should make it show up, but i think only firmware 2.0 will be able to play it.
