OK. These trailers/test samples are the only truehd content I have so I didn't really try or look for them before (or I forgot).
Anyway, 0.18 works. The audio decoder also shows 32float under decode in 0.18, and not 16int like in 0.19. |

Thanks, i'll fix it for the next version then. Its not that important, no-one should want the AC3 stream when he can have TrueHD :P

Only today I found the will to (start to) test these DLLs.
My first impressions: - it is a source filter and a demuxer at the same time, why not use two separate "modules" ? - the "volume meter" of the audio decoder is t00 sl0w , and supports only up to 8 channels ; - how about including a channel mixer and a frequency resampler ? |

First off, its alot easier to get direct access to the IO then relying on some other filter, second, i didn't really see the big point of separating it yet. That said, there is a point on the TODO to allow to use a separate source filter for streaming content and whatnot .. but all in due time. Quote:
Also, i have never seen an audio file with more then 8 channels (in fact, it would probably cause funny issues with the decoder in general) Quote:
The decoder itself will not get resampling, the post-processing filter would.

nevcairiel - quick note to say that I'm really impressed with your splitter and audio decoder. Both are looking rock solid over a range of various content and suit my setup down pat.
Thanks again for your work and I look forward to the Blu-ray support in the splitter. Nathan |

there seems to be a problem with seeking with large matroska files with 24 bit 7.1 dts hd ma audio.
it seems to cause like a memory leak. I'll see if i can make a sample. edit: I can't make a sample, the problem keeps fixing itself in samples, argh. I updated to a newer build of mpc hc, and now it refuses to seek at all. I know this is quite vague, but perhaps you can make sense of it nev? Last edited by mindbomb; 21st March 2011 at 19:56. |

thanks virtual man, but that didn't fix it.
It allowed me to seek through the video again, but playback speed appeared faster than it should have been, with no sound, and it would continue to consume all of my memory. Very similiar to my experience before I updated my player. Last edited by mindbomb; 22nd March 2011 at 21:12. |

All DTS-HD files play perfectly for me.

The LAV Splitter (x64) causes corruption for a few frames right after seeking:

There is no way it creates 2 pins of the same type. Its just not physically possible.
Are you sure its actually using LAV Splitter and not the MPC-HC internal splitter (which creates one pin for every stream instead of offering a stream switcher)

Edit: Process Explorer confirms this: No LAVSplitter.ax is loaded. Edit #2: Something similar happens with the internal AAC decoder, too. I have to explicitly disable it in order to use ffdshow's decoder. Last edited by fastplayer; 24th March 2011 at 10:39. |

Internal filters have a higher priority then external ones, even if you set external ones to preferred.
I thought that was a widely known fact

Examples: a) If I set "Microsoft DTV-DVD Video Decoder" to prefer, it will be used for h264 even if both internal h264 decoders are checked. Uncheck Microsoft, and the internal ones will be used. b) If I set "LAV Audio decoder" to prefer it will be used for AC3 even if the internal AC3 decoder is checked. Uncheck LAV Audio and internal will be used. c) If I set "LAV Splitter" to prefer it will not be used for TS if the internal MPEG TS splitter is checked. Internal must be unchecked to be able to use LAV Splitter. I actually like the behavior in a and b better than in the behavior in c, because in a and b prefer always means prefer, and if the connection to the preferred filter fails from some reason then it can fall back to the internal filter since it's still enabled, just not prioritized. EDIT: This makes it even more inconsistent. Not just a source vs transform filter issue. LAV Audio decoder can be set to prefer even if the internal AAC decoder is enabled. With ffdshow audio set to prefer you still have to disable internal AAC (tested with fastplayer's sample). No wonder this is confusing. Last edited by Ger; 24th March 2011 at 15:46. |
