Need to lower max bitrate for PS3 streaming.

[Orangetang]

I used MKV2VOB to convert my entire collection of MKV, using the default settings. They now have the .mpg extension, and most play great on my PS3. I'm streaming them from a DNS-323 NAS running mediatomb, over a gigabit network.

The problem I am having is with files that have high bitrate peaks above ~15Mbps, usually 1080p videos. They'll stutter and have trouble streaming intermittently.

I want to re-encode the files to have a lower maximum bitrate, and was wondering what program or method can be used to achieve this. I'm willing to change the container type again if needed, but really any PS3 compatible format would be fine.

I've tried a handful of programs including TSMuxer, RipBot, ReStream, but none will open the files that MKV2VOB have made. GSpot only gives the following container info, and nothing else;

File type: MPEG-2 Transport Stream
Mime Type: video/mp2t

:thanks:

Hi!

As you know, the Gspot information you've provided is of no value regarding solving your problem. Therefore, in order to possibly help you, please advise:

When you initially created your MKVs, presumably from BluRay discs, what software, procedures, and video and audio codecs did you use?

Presumably your encoder can be configured accordingly?

I used AnyDVD HD to rip the BluRay to my hard drive, and then used RipBot264 to transcode to x264.mkv, if that makes sence. I remember installing ffdshow, and haali or something, which RipBot needed... whatever worked at the time, and with mostly default settings I think. I'm not 100% sure, it's been a while, and I don't dabble with encoding very often.

RipBot can't open the files ever since running them through MKV2VOB, otherwise I think you are correct.

Just looking for an alternative application. From what I understand MKV2VOB just changes the container format to m2ts or mpg, whichever works for the PS3. The process is incredibly quick, so I would assume everything is still x264 / AC3.

I used AnyDVD HD to rip the BluRay to my hard driveFor those videos that are now problematic because of bitrate, I'd suggest you simply re-rip the original BluRays to your hard drive and then use either "multiAVCHD" or "AVCHDCoder" to convert to a format and bitrate that is acceptable to your PS3...

Wait a second...

1) The idea is to play movies on a PS3
2) The source material is a BluRay disc
3) PS3s can play BluRay discs
4) ???
5) Prophet

1) Re-read the initial post:I'm streaming them from a DNS-323 NAS running mediatomb, over a gigabit network.



2) And anyway, surely you know that many, if not most, members (and others) prefer not to risk damaging their original discs

I'm guessing that the MKV2VOB files with the .mpg extension are not actually valid mpeg files and thus wont open properly in a lot of programs. Do you still have the .mkv files or did you delete them after the conversion?

If you still have them then you use program like MeGui to re-encode them with a lower bitrate. Otherwise you might have to use a program like MKVToolnix to demux the audio/video from the fake .mpeg file and go from there.

Either way I know that there are PS3 media streaming apps the stream .mkv files so maybe you should look into that.

I have some of the original MKVs, but deleted the majority, since I thought I was in the clear. I think you are right about the non-valid mpeg format. It sounds like MKV2VOB just changes the container type of the file. Gspot doesn't even know what kind of file it is.

I'll just re-rip the discs and encode them at a lower bitrate, or at 720p. Thanks all for the help.
