PS3 compatibility

[alturismo]

Hello,

i have a small problem with making .mkv movies compatible with my ps3

my current steps are

MKVExtract -> getting my video.264 and audio.ac3
--->>> here is also my problem, extracted video file is always on lvl. 5.1 wich is not ps3 compatible

meGUi -> reencoding audio to aac
--->>> works

meGUI -> mux video.264 and audio.mp4 to movie.mp4
--->>> as video is still lvl 5.1 plays on pc but not on ps3

YAMB -> extract movie.mp4 to raw format

meGUI -> mux movie.264 and audio.aac to movie.mp4
--->>> now video level is fine and playback also works in ps3

question is, any "patcher" available to patch video before all the muxing / demuxing,
or another extractor to get video in highest 4.1 level from scratch on demuxing ? YAMB cannot handle .mkv to demux it seems ...
mkvextract doesnt give me any options ...

thanks ahead

before muxing change level, see:

or I think Yamb can mux mkv into m4:

But maybe source AVC-Stream is really Level5.1, then changing level might not work.
But so we come to the question why you don't recreate from source... or in another way: where did you get mkv-files?!
... and some nice forum rules, like rule 6:

the PS3 will not play 5.1 audio unless it is a DVD video or Blu-ray movie, it will downmix to stereo otherwise

wouldn't it be quicker just to put the mkv as it is into Nero recode and export it as AVC at 16mps with 5.1 AAC audio?

We talk about AVC Level 5.1 and AVC Level 4.1. That are flags in the Videostream. They have nothing to do with AC3/AAC 5.1 Surround Sound and the count of channels.

PS3 rejects all videostreams with AVC Level higher than 4.1.

I have been reading a lot of topics, what is a good way to take a mkv file, and convert/encode it into a compatible PS3 format? I don't care if it results in a large file size, or the audio is just L and R.

Too many questions, too less infos!
mkv = video container format, unless you give further infos about content you can't get an answer:

What sort are your mkv files?
What codec for video stream, what codec for audio stream?
Easiest way, if video ist AVC Level 4.1 and audio is AAC-LC:
Demux into raw streams, remux into mp4. Use tools in post 1 and 2.

if audio != AAC then recode audio!
if video != AVC then recode video!
if video = AVC and NOT Level 4.1 then change level (see post 2)

if file = unknown source then don't ask here

I posted this in the other PS3 topic:

Just wanted to post a bit of software some might find useful

Drop a H.264 elementary stream onto it and it will essentially do the hexediting to change High Profile@5.1 to High Profile@4.1. Won't work correctly or do very much for anything else.

It's very quick, and I think it can't do any damage.. but no guarantees ;)
