Processing m2ts format video

[vcmohan]

From a Sony HDR-SR5 AVCHD camcoder I have transfered the video to my computer using the Sony supplied software. The files are in m2ts format. I tried opening in Videodub using Avisynth script DirectshowSource. It opened allright but I find the video has been repeated many many times.File info shows
1440 x 1080
1387.347fps (721mico seconds)
74853 frames (0:53:95)
data rate 34521643 kbps
audio stereo PCM 16bit 48 khz etc

from the number of frames and fps the video should be 53.95 seconds but videodub shows 1:17.783 and is set to play for hours. I also noted Haali media splitter Icons appearing in the tray

When I play this file directly in Media Player Classic it plays correctly and the info itshows are
1920 X 1080
MPEG4(H264) 1440 X 1080
1387.35fps
Audio dolby AC3 6 ch 48khz

When I tried using DGIndex ( version 1.4.9) it aborted with message
"no video sequence header found"

Search for m2ts processing in the forum did not help.
I could not understand the descrepancies.

How do I process this video?
a) convert to standard DVD format and
b) Keep in HD format

The video is encoded in H264, you will need to use DGAVCIndex instead of regular DGIndex.

Or DirectShowSource and GraphEdit to make your own filter graph.

Haali Media Splitter -> CoreAVC or FFDShow should do the job nicely.

I tried it also. DGAVCIndex gave first message
"found NALU w/forbidden bit set. bit error. lets try"
on going further
"found NALU type 0, len 16 undefined.
ignore NALU moving on"
next it crashed.

You have to demux the video first. Don't you read help files?

Yes. I have demuxed with TSRemux and tried all the 3 types of output formats (video stream )it produces viz: m2ts, ts and BlueRay bdmv.

M2ts and ts both produced same result with DGAvcIndex I mentioned in my earlier post. When I input movieobject.bdmv then it has pointed out about 4 times NALU being 0 etc. Finally it seemingly completed. I, however, did not see any .dga file output anywhere.

Is there any other software that I need to use (may be m2ts to avc conversion?). Movie player classic has played them2ts and ts demuxed ouputs

Can you post a link to a sample of your m2ts stream?

[vcmohan]

the m2ts file is here (http://www.avisynth.org/vcmohan/sample.m2ts) After you test I will remove it.

I was able to get the .M2TS file to demux using Xport.exe

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

Xport -h sample.m2ts 1 1 1

This creates a bits0001.mpv which DGavcindex will open (after a few warnings). Then save the index to bits0001.dga


load_stdcall_plugin("yadif.dll")

avcsource("bits0001.dga")
converttoyv12()
yadif()
bicubicresize(640,352)

I have about a hundred short clips to be edited and compiled. This procedure appears to be too much of deterrent to me. It involves a demux with command line arguments, then avcindex which gives warnings, then the Avisynth script. Is there a easier method?

CoreAVC Pro $15
Haali Media Splitter

DirectshowSource("file.m2ts",fps=25.0)#or the fps of the camera

You can try a very recent build of ffdshow instead of CoreAVC, but I've found CoreAVC to work a little better with Directshowsource http://downloads.sourceforge.net/ffdshow-tryout/ffdshow_rev1711_20071220_clsid.exe?modtime=1198176465&big_mirror=0
