I have found another bug:
When in dgavcindex, and you load a h264 file, it indexes correctly. If you then close off that file and load another file to index in the same instance of dgavcindex, the file is not indexed correctly. The second indexing results in the following two lines not being added to the very start of the index data: SPS 1 PPS 31 0 If you close of dgavcindex and load the same file, these two lines and correctly added. The result of these two lines not being in the indexed file is that the file still encodes, but at a significantly slower speed. x264 drops from utilising approx 95 percent of cpu down to around 50 percent. This alone does not account for the speed drop of the encoding by a factor of 10! I don't know what those two lines mean, but their importance is obvious! This is using the latest 1.0.0 alpha 34 version. |

I can't duplicate it. The two DGA files are identtical for me.
Please provide the two files and describe the COMPLETE, EXACT sequence of operations that lead to the problem. E.g., when you say "open another file" tell me exactly how you do that. Thank you. |

It happens with any input .264 file, including the h264 output from x264 from a newly encoded file. Without fail, load once its ok, but even if you reload the same file in the same instance of dgavcindex (that is, remove it from the file list dialogue and re-add it), and open, then the output of the .dga file is missing those two lines! The rest of the file is identical.
Here is an excerpt: First time open: PHP Code:
PHP Code:
Additionally, have just found that if I click save project, save it under any file name, then straight away do a second save (with a different name of course, for comparison), the second file has those two lines missing! What do they do anyway? Last edited by burfadel; 19th August 2008 at 19:32. |

dgavcindex alpha 34 crashes when demuxing a .ts stream AAC audio
Trying to demux a DVB-T stream with AVC video and AAC-HE LATM audio.
The application crashes part way through the way with no useful (well to me anyway) error messages, just the usual Windows error messages. Since the file is quite large (3.3g) I have been trying to isolate a segment that can cause the crash. This has not proven to be easy. Cutting the file to include the frame where the crash happens results in a file that doesn't crash . So after lots of trial and error I have managed to create a file that will crash and have uploaded it here. www.datamix.info/stargate.ts Sorry can't make it smaller than the 90Mb it is but I have found that even if I reduce the beginning of the file by a few meg (but still include what I think is the bad segment), the crash doesn't occur. This leads me to think the crash is caused by a sequence of data - not just the data segment where the crash occurs. I am using TS Packet Editor to edit the .ts files. Any ideas on what is happening greatly appreciated. Thanks Larry Last edited by lchiu7; 24th August 2008 at 04:22. |

I just tried opening an exe file and DGIndex crashed after a lot of libavcodec warnings. As this is clearly not intended usage i'm not sure if you want to fix this, too. If yes just say so and i'll upload the file for you.

I don't know lol, I watch Stargate in SD here and this looks tons better, even after I filter and resize the SD Stargate :X
If this is really an upscale, then oh wow. (and we should probably move to PM since it's turning into more than 2 posts :x) Last edited by Comatose; 24th August 2008 at 15:20. |

I am intrigued what software you used to play the stream and did you get audio? [Will go PM for the rest] |

Minor bug report. DGAVCIndex promptly crashes when attempting to save a project if the input file has no extension (after clicking "Save" in the "Save As" dialog).
The input file is a transport stream. It opens fine and everything works up to the point that Save is clicked. When DGAVCIndex crashes, the error reports that an attempt to access memory at 0x00000001 is being made. If I add an extension back to the file, it can save without any problems. FYI, when using DGAVCIndex I am currently only trying to obtain the start and end "RANGE" values. These are extremely helpful when using TS cutting applications that accept byte offsets, so I'm very grateful that info is included in DGA files. Keep up the good work. Greg |

I extracted the video and audio part from a bluray already on my hard disk. The video is ok, but the .pcm audio isn't playable by Media player Classic and VirtualDubMod cannot import.
How can i use it?Many thanks!! |
