I will attempt it myself. No ETA. It works in the JVT decoder, so there is an extant example of how to do it.

Hi,

I just tested this software, but it doesn't work with the streams I use. I record from satelite with DVBVier PRO in .ts and .mpg format, but it seemd DGAIndex doesn't like the streams I record. Does anyone have an idea what I can do to solve it?

BTW: The most common errors are:
1. "Found NALU type 0, len xxx undefined, ignore NALI, moving on"
2. "Found NALU w/ forbidden_bit set, bit error? Let's try..."
3. "Garbage at start of bitstream... skipping it"

Yes. As clearly stated several times in this thread (in bold!), if you want support make an elementary stream available for testing. You see, my magic wand is broken, so I have to do it the old-fashioned way.

You didn't try to open the TS or MPG file, did you? I haven't added container support yet, again, as clearly stated several times.

Hehe, I did. I demuxed the movie now with elecard xmuxer and DGAIndex works. Bit while opening the .avs script I get this error:

AVCSource: Could not open one of the input files (test.avs, line 2).

PM'd you links to another file that doesn't seem compatable. This one is from another channel and it is 720p. Basically the same behavior except that ffdshow will play it fine. File indexes fine but no decoding.

Please provide the stream if you want support. Thank you.

Your first one was PAFF so forget it. This second one appears to have no IDRs or recovery points, which confuses the heck out DGAVCDecode. I'm investigating further because libavcodec does spit out a good first frame, so DGAVCDecode ought to be able to as well.

EDIT: The second one does have recovery points. Should be decodable...stand by.

Hi,

I recorded a new stream (10 MB) for you, but now I get "Field pictures not supported". Since I don't know how to cut my old streams (a ~6GB), I can't send you a sample yet.

I can't get it to work

DGAVCIndex works just fine, as it generates a dga file. Then I create an avisynth script like this:

Code:

loadplugin("DGAVCDecode.dll")
AVCSource("tloeg.dga")

But when I open it in Vdub, it says

Code:

Avisynth open failure
AVCSource: Could not open one of the input files.
F:\Download\tloeg.avs

The first chunk of the dga file looks like so:

Code:

DGAVCIndexFile2

F:\Download\tloeg.avc

Some problem here...

Guest · 15th March 2007, 13:51

I need a stream to help you. I am getting tired of saying it.

thany · 15th March 2007, 14:36

Alright alright, here you go.

Unfortunately, the whole stream is a little too much (like, 13GB), so I'm only publishing the first 1MB. Hope that's enough.

Guest · 15th March 2007, 16:38

Rename it to "tloeg.264"

I'll fix that in the next release.

thany · 15th March 2007, 20:28

Works like a charm, thanks

Eastermeyer · 16th March 2007, 16:42

Just tried to use DGAVCIndex. But the Indexing-Tool isn't doing anything , even after an hour.

I am using WinXPH SP2 and a raw h264-File created with Haali Splitter / Dump Filter (Graphedit).

Here is a 15MB Sample cutted with a binary splitter from the beginning auf the h264-file :

It doesn't look like an ES and VLC crashes when trying to play it. Also, Elecard XMuxer doesn't like it. So it's not a valid ES.

What is the original container format?

Eastermeyer · 16th March 2007, 18:07

TransportStream.

Oh I am very sorry , it seems to be Haali Splitter's fault. It seems to work with a File demuxxed by Intervideo Filter. But it's PAFF , so unsupported.

Guest · 16th March 2007, 18:52

I'm beginning to get disillusioned with libavcodec. I keep running into crashes and obscure bugs. I am unable to debug/trace the code due to the inability to build it in my windows development environment. And of course the lack of PAFF is very irritating. So I am considering starting again with the JM reference software, which I can actually build and debug in my environment. It should be possible to optimize it to an acceptable level (borrowing from libavcodec source for key things like transforms, etc.). Then we would have proper open source for a full featured decoder that is usable in standard windows development environments, as opposed to kludgy pseudo-unix environments.

Any thoughts?

Adub · 16th March 2007, 18:58

I have to admit, that is a good idea. But you have to consider, would it be easier to start from scratch, or to just go through the old code of libavcodec and make bug fixes and so on. Personally I don't know enough code to make a judgement on this, but if you feel up to it neuron2, more power to you.

In short, I vote for the whole overall and start from scratch idea.
