those are not correct raw avc streams. there is something wrong with the headers the same way as they are wrong when demuxing with other tools
Yes.

drmpeg,
I saw your post:

Very interesting....

but say to me, where did you find these working tools.
Do you know other method to demux .m2ts ?

Demuxer used inside Elecard player could do this without a problem - http://www.elecard.com/products/prod...r/mpeg-player/

Elecard's AVC DSdec v1.0.27 Build 60705 (2006-07-12) with Haali can also decode Ron's elementary streams muxed into MP4 using YAMB

I neglected to mention...

Elecard's AVC DSdec v1.0.27 Build 60705 (2006-07-12) can also decode the original .M2TS sources, using MediaPlayer Classics internal .TS splitter

I'm hopeless with commandline tools. Can anybody make a GUI?


Cheers

looking at this on page 21, it seems .m2ts is the extension for the video streams on bluraydiscs, so propably this sony cam tries to create bluray compliant files

.M2TS is usual exetension for MPEG2 Transport Stream files. MPEG2 Transport Stream is used in Blue-Ray, HD DVD, DVB S2, DVB T/C/S, in other models of Sony cams with MPEG2 Video both SD and HD resolutions, and in many more cases.

That's correct. It should also be noted that .m2ts files are for Blu-ray and AVCHD only.

The typical Transport Stream used in broadcast (ATSC, DVB-T,S,C, cable QAM and others) is a constant rate bitstream. However, the .m2ts format is intended for storage on blue or red laser optical discs.

It would be a waste of space to use a constant rate Transport Stream, so a variable rate Transport Stream is used instead. In order for the PCR (and clock recovery) to make sense, a 4-byte timestamp that represents arrival time is added to each 188-byte packet.

The timestamp allows playback that can reconstruct a constant rate (and T-STD compliant) Transport Stream from a variable rate stored bitstream.

Ron,
Given that each blue laser camp uses its own - and different - format: program and transport stream, do you find any of them preferrable for the task at hand: reliability, security, encoding, etc.

Does HD-DVD use "standard" program streams?
What could be BD's reasoning for coming up with a new VBR trasport stream?

Thanks.
Diogen.

you should look at the directory of a bluray disk and the directory of a hddvd disk. the hddvd directory (HVDVD_TS) is just the video_ts structure with different filenames. (ifo, bup and evo(vob)) the ifo files are even still stamped with text of the type (hd-dvdvmg100 or standard-vts) at the beginning like dvd ifos. the vobs(evos) and ifo internally are similar as well. vobedit can read a .evo (although it interprets most of the data wrong.. it gets some of it is right)

blu-ray disks carry a completely different structure. hddvd was built on top of dvd. blu ray was built from scratch (as a disc format i should say)

Yes, HD-DVD .evo files are exactly like SD DVD .vob files. They are standard MPEG-2 program streams with an additional audio stream id in the audio PES.

The choice of TS for Blu-ray is about recording. It's easy to make a .m2ts file on the fly. Just discard stuffing packets and add the arrival time timestamps before you store to optical or hard disk.

Ron

How do I use xport to demux the ac3 audio? The readme says to use the -d but I can't get that to work.

Sorry, it's a mistake in the readme. It is supposed to say the -n option.

For example:

xporthdmv -n ezsm.m2ts 1 1 1

The -d option dumps the PID for each packet.

Thanks Ron, that worked! I don't know if anyone can help with the next question I have. I am trying to get a workflow on OS X to convert it into something usable by Final Cut, your tool compiles and works without a problem, but I haven't found anything that will decode the CABAC interlaced video. Has anyone been able to play or convert the demuxed elementary streams using linux tools?
