But keeping in sync with the upstream repository is trivial!

I don't know git, but it can't be worse than svn
To all, please test r3602. Things to test: a) Audio channel mapping is fine for 5.1 streams and above. Fine means the same as in previous revisions. b) Yadif works fine. Please test on CPUs without SSSE3, SSE2 and MMX2, or any combination of them. If your CPU has SSE2 but no SSSE3 for example, test it. Fine means it doesn't crash and the speed is the same as before or within margin of error. Build: http://www.mediafire.com/?l90nft4ccgam2o4 And to the devs, mplayer now only contains mp3lib, which is IMO not needed at all, with libavcodec and libmad. We can remove it and libmplayer will be gone. |

And sorry to beat a dead horse(I know, that's my speciality ), but would you have any idea how to enable PCM24/32 for winamp DSP plugins? the input/output is currently downconverted to 16int, which is a major bummer as there's many DX/VST plugins wrappers...and ffdshow is the perfect place for this kind of job You can see tons of "int16_t"/"SF_PCM16" in those sections: http://ffdshow-tryout.svn.sourceforg...p&pathrev=1928 http://ffdshow-tryout.svn.sourceforg...p&pathrev=1928 winamp2 DSP plugins work in PCM24/32 using the foobar wrapper: http://wiki.hydrogenaudio.org/index....oo_dsp_winamp) Quote:
Christian Budde(a professional VST plugin coder) helped Haruhiko to iron out a few bugs in the winamp DSP plugins host code of ffdshow, and confirmed that PCM24/32 were entirely possible w/ winamp2 DSP plugins. If anyone's interested, I could make a complete tutorial to VST awesomeness in ffdshow...including upmix/downmix matrixes based on Lexicon's Logic7 routines. The key is to calibrate their coefficients to your gear/brain. Its author, David Griesinger, is the living god of audio DSP for hometheater use. After a bit of work, you can make very convincing stereo downmixes(very short FLAC samples): http://www.mediafire.com/download.php?hzgj3fsco1gqsbf http://www.mediafire.com/download.php?xrfcj9rm2od453k Quote:
One thing I've never understood about double frame rate deinterlacing is that it looks like frame interpolation...It really looks as if I were watching a 59.94fps source, when it should actually be 29.97*2 A friend of mine is completely hooked to 1080i*2 on his projector, he finds the picture WAY smoother.

But right now, libavcodec DTS and VST plugins are stuck to 16int in ffdshow Last edited by leeperry; 28th September 2010 at 01:30. |

I'm glad you enjoy your 64-bit double placebo. The rest of us live in reality. Last edited by kieranrk; 28th September 2010 at 01:44. |

they took a 29.97fps progressive source, once properly deinterlaced it should be reconstructed to 29.97 progressive...no need for frame interpolation. anyway, I don't care for interlaced stuff...I have a bunch of poorly authored DVD's using it, that's all.
oh yes, placebo...good thing I didn't tell you about software induced jitter, I don't think you'd be ready for that just yet. and in case you were wondering, you can measure it too...so much for placebo. even a 11yo girl can hear the difference, but she has better hearing than you and I. foobar's volume attenuator also works in 64fp, just like all the pro-audio software....anyway, my original point was that 16int for lossy audio decoding and post-processing butchers the SQ.

Second, you should really learn what interlaced video is. If you have 29,97fps pure interlaced content you have 59,94fps of temporal information there. Outputting 29,97fps is an abortion, but needed in some cases. That's why deinterlacers have that option. OK. What about theora? It hasn't been included in the installer for quite some time, why is still there? Last edited by STaRGaZeR; 28th September 2010 at 11:52. |

That XXHighEnd developer and the people that buy into his overpriced software sound a bit loony to me. You can still measure something with a sensitive device and yet not be able to sense a difference and so you would be subject to a placebo effect. I could point out the differences in spectral patterns of two stars to determine that one is of slightly different composition, but I could never see the difference with my eyes.

If you had a bugtracker anyone cared about, this wouldn't be happening...bumping bugfixes requests is the only chance to see anything happening(just like MPC). I've asked three very skilled audio plugins coders for help and they've all told me that the ffdshow audio code was a bug feast(full of syntax errors and beginners mistakes) and a huge mess...so I guess this is not going to change anytime soon. They were even wondering how it could be working at all ffdshow is a lost cause for studio grade audio, atm it's just a toy to watch movies in WMP...sorry for rubbing it in Last edited by leeperry; 28th September 2010 at 15:53. |

I haven't seen yadif leaving residual combing in neither single nor double-rate mode if the spatial deinterlacing check is enabled (not skipped, modes 0 and 1 in the MPlayer implementation). Do you have a sample clip?

so videos shot interlaced actually have 59.94fps, great! that would explain why my friend is so hooked to 1080i concerts on his projector...but I believe he also likes 1080i movies, that can't possibly have more than 24fps AFAIK(IVTC put aside). |

And for FFmpeg speed (even on non-mainstream platforms) is most important than output resolution. But if someone sends a patch to fix this issue, there'd probably no objections to changing the output format. |
