|  mkv4ps3.pl - convert mkv files to mp4/avi for the PS3
I decided to put together a script that would be able to convert an MKV file into a compatible mp4 or avi for the PS3. This uses all open-source tools and while I tested it on FreeBSD, it should also work on Linux/windows(cygwin), assuming the path to the commands is found, etc.
Anyway, in a nutshell it does the following:
* for 720p source
- split mkv into ac3/h264
- modify h264 header to change level_idc to 0x29 (4.1)
- transcode ac3 to aac (keeping channel mapping proper)
- remux to mp4 with mp4box
- split the resulting mp4 into 3.5G chunks since the PS3 doesn't like mp4 files that are too large
- for h264 streams that are incompatible, you can use the -target option to specify you want an xvid/ac3 avi (see 1080p source)
* for 1080p source
- transcode from mkv (h264/ac3) to avi (high bitrate xvid/ac3), leaving the audio track intact
- or, transcode the h264 stream to a High@4.1 compliant h.264 stream and mux that with a transcoded AAC as with the 720p files into an mp4
Right now, all the transcoding is only doing 1-pass. I'm going to look into adding 2-pass later, but for now this should give you a file that will happily play back on the PS3 either locally or streaming (I use ushare to stream, works great).
I wish the mp4 file size limitation would be fixed, since the PS3 will play back an AVI that's larger than 4GB just fine.
Anyway, here's the link:
mkv4ps3.pl
Enjoy! Feedback appreciated! I tested it fairly thoroughly, but was up late writing it so there may be a few bugs I'm unaware of.

| I tried your script, but received an error:
Cannot open temporary h264 file
I tried running the script as sudo , in a directory with chmod 777 priviledges, plenty(?) of disk space and still get this error. I don't know perl well enough to debug. Thanks for your help. |

| Which of those commands were you running when you got the message about not being able to open the intermediate h264 file? That I would only expect if your target mode was mp4, since that's where it:
- splits mkv into .h264 / .ac3
- change the header in the h264 (if necessary) to indicate High@4.1 profile
- transcode .ac3 into raw .wav then to .aac with neroaacenc
- uses mp4box to re-mux the .h264 and .aac into an .mp4 container
Do you get an error going to .avi? If so, it should be a different one...

| Ahh ok, kind of a "bug" on my part. If you specify -target mp4, it assumes you want to re-encode the h264 stream.
Try:
/home/johnz/mkv4ps3.pl -in Ratatouille.mkv -out Ratatouille.mp4 -tmp /sdb3/tmp
If that still doesn't work, try running this manually and paste the output:
mkvextract tracks Ratatouille.mkv 1:rat.h264 2:rat.ac3
That's essentially what it's doing when it targets the mp4 output. It seems like mkvextract isn't working for some reason, either because it's unable to parse the right track #s for the input file or there is perhaps a bug somewhere that this particular mkv is tweaking.

Hmm, I just realized that I "released" this script back before I had realized that ffmpeg totally hoses the audio channels. I gave up on it and use mplayer and neroaacenc now. I'll update the script to use that instead, might take me a few minutes, but should be able to do it tonight.

| You're welcome, glad to help!
Ok, I added a -v option (verbose). I also updated it to use neroAacEnc (so if you don't have that, get it ).
Here's the link to the updated script:
»pflog.net/mkv4ps3.tgz
Run the same command you ran before, but add -v, e.g.:
mkv4ps3.pl -in ... -v
Then paste me the output when you run that.

If you already grabbed it, grab it again. I found for some inputs, mplayer did NOT like the ac3 file. So I'm using ffmpeg to dump the ac3 to wav, then using the wav as input to mplayer to change the channel mappings.

| Hmm, looks like the output from your mkvinfo is not what mine is, as it's unable to parse out the necessary information.
Grab the script again (I just updated it), and run it like this exact command (don't include -target mp4):
/home/johnz/mkv4ps3.pl -in Ratatouille.mkv -out Ratatouille.mp4 -tmp /sdb3/tmp -v
Then paste the output.
Right now, using the .wav as an intermediate file for the encoding with nero is causing the channel mapping to get screwed up. Looking into that, but for now, I'd like to find out why it's completely not working for you. In the mean time, I'll work on getting the channel mapping fixed.

Hmm, same as a previous error. "tmp.h264" does not exist. Given that I had success with:
$ mkvextract tracks Ratatouille.mkv 1:rat.h264 2:rat.ac3
is it possible to "patch-in" the rat.h264 and rat.ac3 files into your script so it can move on to the next step? I also notice that your script extracts:
3:/sdb3/tmp/tmp.ac3 5:/sdb3/tmp/tmp.h264
and the successful command extracts:
1:rat.h264 2:rat.ac3
Are the wrong tracks being extracted? Is the full path name screwing it up?? Is tmp a bad choice of temporary filename? I am lost :-( |

| It looks like the multiple audio tracks are confusing the script. Can you run:
mkvinfo Ratatouille.mkv > rat
gzip rat
Then attach rat.gz to this thread, and I'll fix the parsing algorithm to properly handle cases where the mkv has multiple audio tracks.
