AVCSource("file.dga",deblock=false) I'm sure you're aware that in H.264 the deblocked picture becomes the reference picture, so you may see inaccuracies that get progressively worse within a GOP. It will be in the next alpha. The next alpha will also add an option to DGAVCIndex to generate a decoded video using the JVT reference software. EDIT: It's 25% faster without deblocking. For one 25fps HD clip I have that made the difference in allowing me to play it at full frame rate. Last edited by Guest; 6th March 2007 at 07:32. |

I'm aware of some of the drawbacks, but in certain cases it just works better without it.

first of all, thanks neuron2 for the great work!
my workflow looks like this: Pro7 HD Transport Stream => mux to Matroska => cut with mkvtoolnix => demux with mkvextractgui => index => avisynth i want to report the following issues: - in your GUI, you can add files via drag&drop. after add file via D&D => index, if i drag another file into it, the indexfile will be created, but if i want to load it, an avisyntherror occurs: no video - if i load a file, which was splitted with mkvmerge and demuxed, DGAVCSource looses the first ~60 frames, compared to DirectShowSource("file.mkv"). |

LoadPlugin("DGAVCDecode.DLL")
AVCSource("D:\HD\sky.dga") Everytime I try to play the AVS file I get this message: Evaluate: System exception - Access Violation the streams are the ones from x264.nl |

neuron2 : can't you try to copy the decoded picture in the output buffer before deblocking it ? That way, there are no decoding accuracies.

Hey,
Maybe it is possible to make avc/h264 support for satelite hdtv avc streams? Sample from FTA channel below: Sample File |

My guess is that it is PAFF, which is not supported. But I'd like to see the stream to verify that and to test out a more graceful exit. Last edited by Guest; 6th March 2007 at 17:31. |

Okay I just tried this on another video and getting some strange issues when trying to fast seek to certain points. I don't know if this has anything to do with the IDR/SEI issues you mentioned.
1) The video is 640x480 @ 60fps and 400334 frames long. 2) I CAN fast seek anywhere in the video from frame 0 to about frame 189257. If I try to fast seek anywhere past frame 189257, VirtualDub will return me to the beginning of the video. When this happens I can even press "play" and it'll start playing at the begining of the video. 3) Furthermore, if I try to fast seek past about the frame 377623, VirtualDub doesn't even go back to the beginning of the video. Instead it shows a blank green screen. If I press "play" at this point, VirtualDub will play the green screen and sometimes the real video will shift in and out during playback. 4) Fortunately, none of these problems occur if I just press "play" before the 189257 frame. I can play all the way through the video and just press "stop" and it'll stop at the right spot. Unfortunately, this is a lot slower than just fast-seeking. 5) This also causes a problem with the trim command. If I use trim(0,185000)+trim(370000,0) and I set my mark to lets say 184000 and press "play" in VirtualDub, by the time VDub plays past the 185000 frame it starts playing at the beginning of the video. I haven't tried any encodes doing this yet (I plan to later), but I wouldn't be surprised if it screws up the vid. 6) I have not encountered any of these issues using DirectShowSource on my original .mkv. I'm going to remux the .264 file I demuxed back into another .mkv and play it back to see if MKVExtract made a mistake probably later today. EDIT: I just remuxed the .264 file I originally extracted and it seeked fine with directshowsource, so obviously MKVExtract can't be the culprit. 7) The entire .264 file is 4.21 GB. If you're interested, I might be better off sending you a DVD-R in the mail.

Neuron'll lynch you for not demuxing it...
