Unfortunately, it's the default setting on the Hauppauge unit, and the only way to access/change it is through the properties in the graph. Hopefully they'll update the software and allow changing it through the software packaged with the unit.

Do you have or need sample streams of any of the other settings on the Hauppauge HD-PVR?

If you have an Amazon account, you can set up an Amazon Honor System account. http://zme.amazon.com/ I use it for contributions on my web page.

I've found and fixed the problem. It will be in the next alpha. If you need it before then send me a PM.

Regarding the spec, I plan to get my employer to buy it.

Some helpful info on the spec from Library Of Congress
http://www.digitalpreservation.gov/f...dd000137.shtml

There appears to be 3 versions of the mp4 file format, the last one is the link above
# MP4_FF_1, MPEG-4 File Format, Version 1 - 2001
# MP4_FF_2, MPEG-4 File Format, Version 2 - 2003
# MP4_FF_AVCE, MPEG-4 File Format for AVC (Extensions; Part 15) - 2004

Other interesting links for specs that start with M
http://www.digitalpreservation.gov/f...e_list.shtml#m


After looking at the .gov site could you use part 12 instead of part 15 since 12 is the base that 15 is built from?
ISO/IEC 14496-12:2005

Just making sure no one here wastes money on the wrong spec sheet, because thats available for free here
http://standards.iso.org/ittf/Public...rds/index.html under
ISO/IEC 14496-12:2005
all 94 pages of it!

Part 12 is the ISO Base Media File Format. Part 14 is the MP4 format that we're so used to. Part 15 is designated AVC specific, and is built upon Part 12. http://en.wikipedia.org/wiki/MPEG-4

No. Part 14 is MPEG4 video in MP4 container. Part 15 is AVC video in MP4 container.

Guys, I'm fully informed on the specs. There's no need to discuss it here.

@all,

as someone told me it would be better to use DGAVCIndex instead of Directshowsource at meGUI I wanted to use it, but it seems I could need some help. I've read the help file and hope that everything is set up properly. I tried opening different H264 Elementary Streams and save them as a .dga project, but I always receive :

Trying to use an invalid (uninitialized) Picture Parameter set with ID 0, expect the unexpected ...

hit yes ......

Anyone has a little clue for me what I am doing wrong ? After hitting yes or no or Cancel I receive that the program has encountered a problem and needs to be closed.

Thanks in advance to you.

It's the same problem as Ranguvar's above. I'll put up the fix within an hour.

This is a Hauppauge HD PVR capture, by the way.
You'll be happy to hear that I have it working now with the Hauppage streams without IDRs. So you won't have to go through the Graphedit route to turn on IDR generation. I'll regression test it some more and release it later this evening.

I did it because I plan to get one of those Hauppage units myself.

You are the man I've been cutting one file a dozen times trying to get it to make a complete pass through, I thought I had it, but it bombed out on the last commercial cut.

@rebkell

I was referring to the problem of the Hauppage streams not having IDRs, and not to your crashing issue. I am still investigating your issue.

I love you!
I had to re-encode the capture to LAGS... except it was 60 fps, so it was IMMENSE. D;

Also, fun fact: CoreAVC doesn't seem to be able to handle this kind of stream... it outputs a ton of duplicate frames (real frame, 20 duplicate frames of the real frame, real frame, 20 dupes, etc) :X

Ok, I thought about that right after I posted, it's pretty consistent, it's definitely a problem with libavcodec(created by h264ts_cutter's cutting), it also crashes media player when it's using ffdshow while trying to play the original cut ts file.

I've recut this one file I've got several times and I've managed to get it through all but one cut, any ideas what I might look for to get over the hurdle?

How did you re-encode if CoreAVC wasn't working?
