Version 1.0.0 alpha 16 -- audio demuxing
This is the first cut at audio demuxing. Notes:
* The paradigm for setup of audio PIDs and demuxing is different than in DGIndex, so read the users manual! This version allows all PIDs to be processed at the same time. (The idea of moving it from the Stream menu is to allow for generalizing it to include MP4 files later.) * AAC LOAS/LATM not yet supported. * AV sync solution not yet decided. Currently, audio starts at the first audio frame after the start of the first decodable picture. * CLI for audio demux not yet implemented. * An audio stream must be listed in the PAT/PMT for demuxing to work. This limitation will be removed in a future version. * M2TS support was fixed. E.g., the "wedding" stream now works if you dismiss the libavcodec errors, which appear harmless. http://neuron2.net/dgavcdec/dgavcdec100a16.zip Last edited by Guest; 18th February 2008 at 00:13. |

Still pondering AV sync issues... I have streams with no IDRs, just recovery points. So your idea is a non-starter. Remember, the first decodable frame is either an IDR or a recovery point. Last edited by Guest; 18th February 2008 at 01:16. |

neuron2, why not start audio at first IDR or recovery point then? Wherever the first decodable video frame is, start decoding audio. Might be a bit difficult for video with multiple slices with recovery points on different frames on different slices (for rate control reasons). hmmm. But then I don't know how you deal with those anyway. (Don't have a sample handy.) |

http://forum.doom9.org/showthread.ph...13#post1100913 @Atak_Snajpera Just for fun I played with h264tsto. It dumps all audio types as files with extension .mpa. How then do you know the audio types? Or don't you care? I also have streams for which it does not demux the video correctly. Last edited by Guest; 18th February 2008 at 04:43. |

I'm trying to open the 1st of the two main .m2ts files for Stranger Than Fiction, but when I try, DGAVCDec crashes after I dismiss the NALU error. Infact, all the .m2ts for that movie crash it.
Just tried the Jesse James .m2ts files, but this time it couldn't detect the PIDs properly. Even tried to set them manually but no go. Then finally, tried the Tudors .m2ts files.. those seem to work fine (except seeking is a little strange). Need some samples? |

I thought you were some master of telekinesis, my mistake. D:
http://www.stfcc.org/misc/stf.clip.m2ts http://www.stfcc.org/misc/jessejames.clip.m2ts Edit: Scratch that.. I must be getting old. Neither of them are AVC. Sorry for the false hope of being able to fix something. >< However, it would be nice for DGAVCDec to give some kind of warning message box saying that the format is invalid instead of crashing.

Just for fun: Neuron2, you could maybe implement a check + error-message that says "Oops, dont recognise this video-stream. Are you shure it's AVC ?". Or if you detect it's MPEG2, "This is not a AVC-stream, but an MPEG2-stream. You might want to use DGIndex instead" Just for all of us that are getting old (like ... me too, as i allmost made the same error ) Last edited by G_M_C; 18th February 2008 at 11:31. |

@canTsTop
Thank you for pointing out the libavcodec update. I'll upgrade. Yes, I missed your other post. I downloaded the video but it was all black. Then I couldn't download the test stream because my "download limit" was reached. Please use a proper upload site or explain better what your problem is. Is it just a case of the stream switching to Frame at the end? That's not illegal or unusual. Why do you think it is a problem? |
