Ok another interoperability issue this time it's seeking related with Mainconcept Mpeg-2 Decoder the result with Lav Splitter looks like this @ Seek
It also happens with MPC-HC splitter (some seek points) but not as heavy as with lav splitter (every seek point) and for every seek, it recovers though shortly after for both. If you hit a I frame @ seek its obviously fine for both . I don't think it's critical for playback though just a annoyance in perception. Different when you think about Editing though via Avisynth or any Dshow Framework involving this combination and a seek operation to a given frame. Im pretty sure this has todo with Mainconcepts Decoder being Frame accurate and ffmpeg failing with that, so no easy fix anyways maybe though trying to workaround this by explicitly forcing a jump to the next I-frame ?.

Thank you very much for .25 Bitstreaming is exellent (ATI + Onkyo)! First time I can bitstream Dolby Digital+. Can not do that using ffdshow. BTW, LAV + reclock = perfect, but LAV + Default audio renderer = some issues (bitstreaming DTS HD MA 2.0) |

Latest install script has a bug. Either remove empty "InitializeSetup" function, or set add a "Result:=True" to it. Otherwise setup with exit at init.

I have finally got around to making a plan to compile LAV Filters
I see this kind of message when compiling, is this normal? The built files seem to be perfectly fine. Code:
5>Media.cpp(489): warning C4267: 'argument' : conversion from 'size_t' to 'int', possible loss of data 5>Media.cpp(493): warning C4267: 'argument' : conversion from 'size_t' to 'int', possible loss of data 4>BDDemuxer.cpp(251): warning C4018: '>=' : signed/unsigned mismatch 4>LAVFDemuxer.cpp(186): warning C4267: 'argument' : conversion from 'size_t' to 'int', possible loss of data 4>LAVFDemuxer.cpp(407): warning C4018: '>=' : signed/unsigned mismatch 4>LAVFDemuxer.cpp(704): warning C4267: 'initializing' : conversion from 'size_t' to 'UINT', possible loss of data

You have to start player with LAV and you can click on filter to select setting.
Or insert filter in graphstudio and you can get it

Will you check this file? Channel_Test_E-AC-3_7.1.m2ts LAV Audio Decoder bitstreams E-AC-3 perfect. But it looks like it decodes only the core AC3 (so does ffdshow Audio Decoder): I can hear no sound from left/right surround speakers. ArcSoft Audio Decoder decodes it correctly. |

There is nothing to check, ffmpeg does not support decoding 7.1 E-AC3, and will only ever decode 5.1

I'm having an issue with VC-1 content
Using PDVD10, I can play VC-1 straight from a BR disc or in a MKV. Problem is that I have a weird video glitch on the very bottom of the frame when doing this. If I use MPC Video Decoder the problem goes away with MKV's but breaks playback from BR disc. I'm using .25 within Media Portal. EDIT: Ok this is odd. I can play VC-1 straight from a bluray using The Dark Knight, but if I try to play a VC-1 extra feature from my Apoclytpo Bluray it doesn't work. Everything loads and seems to be playing, even the disc is spinning, but nothing actually plays. Glad I tested Dark Knight, now I know it isn't a VC-1 issue but rather a problem with the extra features playing on Apoclypto. But I am confused as to why said feature will work using PDVD10 but not MPCVideoDec? Last edited by Ingram; 8th May 2011 at 20:35. |

You can ignore those warnings from inside libbluray, all the others are most likely cases where i'm smarter then the compiler and forgot to override it.

A wonderful sunday evening, everyone!
I worked on further improving bitstreaming today, and the improvements i made are ready for testing. http://files.1f0.de/lavf/LAVFilters-...0-g0ee9d6c.zip Most notable changes: - Fixed a bug that caused certain audio types to not produce a valid media type, causing connections to fail (most notably 24bit LPCM) - Using the ffmpeg parser, which should allow bitstreaming to function properly with other splitters (not extensively tested) - New logic for timestamping bitstreamed (non HD) DTS and AC3, which should resolve some playback issues when not using ReClock. - Better handling for End Of Stream events, it should no longer "eat" the last audio frame. I tested all the bitstreaming formats on my HTPC, and did seem all fine, so here goes for you!

Forced subs auto loading I thought I would never get... Now I can move the dream target to BD menu support as that is the last piece missing from the BD puzzle.

FFMPEG-based Directshow decoders do not yet handle all types of interlaced VC-1 content correctly. PowerDVD's decoder is proprietary and built on a codebase that doesn't have this issue. You can also use the WMVideo Decoder DMO to decode interlaced VC-1 in software or LAVCuvid if you have a supported GPU.
