.idx is used for indexes on squillions of programs - is there an issue with using it in the plugin? |

@ale5000:
I'm open to suggestions.
The current index code is a mess, and after that business with the crashing and the hidden packet entries, I've decided that I have to find a better way to do this. I have some new code up and running, which I'll post as soon as I put it through some fair testing.
The biggest improvement is in memory usage. MPEGPacketInfo is now 8 bytes (down from 16) per packet, and MPEGSampleInfo is 12 bytes (down from 16) per sample.
Unfortunately this will again break all the previous .idx versions...

@fccHandler: The current extension looks good, it is the abbreviation of mpeg index.

Get "CodecMissing" when opening WMV2 in Virtualdub 1.7.6x3 with fccHandler's WMV plugin. Audio plays but no video.
Is this because there is no VFW codec for WMV1 and WMV2?
Thanks for all the work. Virtualdub is really growing up.
EDIT: set ffdshow video codec in VDub to use WMV9 to open WMV7 & WMV8 and now it opens. |

Not that I use Real Media but is there a real media input plugin in the works or is it too messed up of a format to even bother with? |

The RealMedia format isn't too bad, but (like WMV and FLV) it doesn't have a fixed frame rate, and that's always a problem. Codecs might also be a problem. The answer to your question is yes, I'm kinda toying with it, but I don't know yet if it's really going to work.

Thanks.
I usually use TMPGEnc for the WMV files since it usually doesn't cause any sync problems converting to mpeg but it's good to able to open them and any other format in Virtualdub if you want. There are times when putting a different sound track to these formats and converting to AVI is desirable and sometimes you get lucky with one of these files if it was created close to a normal framerate and it will turn out fine.
Thanks for all your hard work. |

Well, I hate to say it, but it doesn't look like this is going to work. The problem is the codec. I've come far enough to where I can extract a single keyframe from one of my .rm files, but I'm not finding a way to decompress it.
I did my best to create correct BITMAPINFOHEADERS for 'RV20' and RGB24, and to my surprise ICLocate() succeeded. It gave me a handle to ffdshow-tryouts libavcodec. Unfortunately the VFW configuration for ffdshow warns that their RV20 codec is "incomplete," and that does indeed seem to be the case. It just crashes when I send it my keyframe.
Unless I can find a solution for this, my RealMedia plugin is doomed from the start. Damn.

If ffdshow is open-source, can't you mod it? |

I've run into a similar problem trying to use FFDShow's h264 decoder on data from quicktime files. ICLocate succeeds but ICDecompress fails. FFMpeg can decode the exact same data, though.
I don't think I'm the one to do it...though I do have a partially working filter already for video only...but an FFMpeg input filter would be nice. My test seems to work for quite a few mkv, flv, mov, mp4, wmv, ogg, mpg and rm (RV10 + RV20, not RV30 or RV40) files...except for seeking and I'm not really sure what it does with variable frame stuff. It also just outright crashes on quite a number of files. I think getting a fully working filter is beyond my capabilities. |

Yeah, but I don't know how to fix it. I only know how to parse the file format (container). I don't know anything about the Real Video codecs. That's supposed to be ffdshow's job.

What I found out today is that ffdshow's DirectShow RV20 decoder works; only the VFW codec crashes. There are different approaches to RV in all of the open source projects I've looked at (ffdshow, realmediasplitter, ffmpeg, and mplayer), and they seem to be using different builds of libavcodec. The RV20 decoder in ffmpeg is quite different from the RV20 decoder in mplayer, and both are different from the ones in ffdshow, and so on. What a mess.
This is turning into way more trouble than I anticipated, so I'm going to put it aside for now. I may come back to it some day, but right now I want to go back to trying to fix the sync issues in my WMV plugin.
