New HD Format - AVCHD (By Sony and Panasonic) - Page 3

MPC ok

SeeMoreDigital · 10th August 2006, 16:30

From what I can see, the AVCHD files max-pain has linked to are "interlaced" with a resolution of 1440x1080/88.

Media Player Classic (MPC) will be able to play them, provided you have the correct MPEG-4 AVC direct-show decoder and .TS parser/splitter installed and configured.

Cheers

MPC was crashing for me, which splitter are you using?

Schmendrick · 12th August 2006, 23:57

With PowerDVD7 installed you will have codecs installed to be able to play this format. It is just a regular transportstream container like also used for DVB-S2 satellite transmission from ASTRA in europe containing an AVC/H.264 video and AC3 5.1 audio stream.

CoreAVC 1.1 Pro (which includes Haali's new .TS splitter)

AVCHD files:

thanks a lot for the links!

the files are .ts with avc video and ac3 audio

the video streams cause problems for libavcodec as they use a paff/mbaff combination
they also use cabac, loop and 2 reference frames (b-frames?)

also the streams seem to somehow not work with mpeg4ip's h264_parse tool which might indicate a wrong bitstream?

Nero Show Time Too, and plays it perfectly (better) than MPC with CoreAVC 1.1 (Two green bands on the top and bottom of the video).??????

Bond, do you think it is only that?

guada2 · 28th August 2006, 22:26

Just 2 questions:

- it is possible to convert this format AVCHD (.m2ts) to AVI ?
- Does exist softwares able to deal with this file or to convert it in another format (DivX, Wmv, DVD, AVC....etc).

Thanks.

.m2ts is yet again a new pseudo format from sony. it seems to be very similar to .ts, but something is wrong with the headers

Indeed.... I'm still trying to get my head around the need for their .M2T file extension (as used in their MPEG-2 HD camcorders)!

bond · 29th August 2006, 18:45

making people think they invented a new format? and then charge for that new format?

2 other questions:

- With the arrival of the AVCHD, can one say that the HDV is an intermediate solution?
- ( The market of the camcorders would be it in crisis? )

Thanks.

SeeMoreDigital · 29th August 2006, 22:29

I don't think so..... MPEG-2 will be a popular format for many years to come, especially as it's roots are firmly embedded in the business/professional sector

In many respects the use of "DV Tape" in high-def MPEG-2 and MPEG-4 AVC camcorders could be considered as an intermediate solution....

drmpeg · 30th August 2006, 01:52

The .m2ts files appear to be captured over 1394 incorrectly, as the 1394 timestamp is present before each 188 byte packet. If the tool or demuxer can't handle 192 byte packets, it will have problems.

Otherwise, the stream is just a normal Transport Stream with H.264 video. The first stream "ezhqp1.m2ts" contains H.264 video that is field only, no MBAFF.

Here's the properly demuxed elementary streams:

Hi Ron,

I've got to ask.... How did you manage to de-mux the AVC streams?

Cheers

drmpeg · 30th August 2006, 09:13

I just modified my xport demuxer tool. The normal 188 byte version is here:

http://www.w6rz.net/xport.zip

It will demux 188 byte Transport Streams with H.264 video. For H.264 video, it does not perform bitstream cutting to the first I-frame and first audio frame associated with that I-frame like it does with MPEG-2 video. I'd like to add the feature, but not enough time these days.

BTW, I was wrong on my previous post. The 192 byte packets are not 1394 packets, they are Blu-ray HDMV packets. This became obvious when I tried to demux the audio. Instead of the AC-3 stream being on stream_id 0xbd, it's on 0xfd. Also, there are specific Blu-ray HDMV descriptors in the stream. In fact, one of them spells out "HDMV" in ASCII.

The PID's also follow the HDMV specification:

0x0 = PAT
0x100 = PMT
0x1001 = PCR
0x1011 = video
0x1100 = audio
0x1200 = Presentation Graphics

There is a "Presentation Graphics" stream in these clips.

UPDATE: the modified version for HDMV streams is here:

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

try to run h264_parse from mpeg4ip over them

drmpeg · 30th August 2006, 22:33

They work fine with my in-house (LSI Logic/VideoLocus) bitstream analyzer. However, I'll try h264_parse.
