ffdshow tryouts project: Discussion & Development
About ffdshow tryouts
The ffdshow tryouts project is a fork of the ffdshow project. This fork was created by a group of members here at Doom9. The last modification to the source code in the SVN repository of the original project was done in may 2006. The ffdshow tryouts project has continued where the original project stopped. Several bugs have been fixed. Lots of code (that ffdshow borrows from the FFmpeg project) has been updated, and also support for a few new formats has been added. Important Notice Development of ffdshow has been discontinued! All former developers of ffdshow have lost interest in the project. There have not been any significant changes to the code since 2012, only some minor trivial changes have been made in the past year. A superior audio and video decoder is available in the form of LAV Filters. Downloads ffdshow builds Links

Having downloaded a newer revision, I'm pleased to see the "multithreaded" encoders bug I posted a while back is fixed, although brutally! I don't know whether it's a ffmpeg bug or not, other people would have to provide me a binary with AVS input so I can test!

Great news... It's about time we had a dedicated thread for this sort of thing

hm, but when using either old and system default renderer in mpc, ffdshow's OSD tells queued output samples are in use.
Therefore shouldn't it be possible to get it work with overlay mixer too?

Hi guys - long time no see...
Anyway, first let me thank you all for keeping ffdshow's development going - it's continually getting better... Now, I really didn't have much use for ffdshow in the last few months, as I preferred watching my DVDs on our TV, but since I bought a projector last week I've been back to using my PC for my DVD watching needs. As DVD decoding isn't working reliably in ffdshow, I've been using Media Player Classic's MPEG2 decoder and postprocessing that via ffdshow's "Raw video" set to "YUV modes". Using a combination of PowerStrip, Reclock, ffdshow and MPC, I've got a great picture out of my Samsung Pocket Imager, at least for stuff that doesn't need deinterlacing. But since most anime is of course interlaced with 3:2 pulldown, I wanted to do the following:
The problem is that resizing only works if I do it before deinterlacing, but I guess I needn't tell you that resizing interlaced material is a big no-no. If I deinterlace first and resize afterwards, ffdshow either crashes or at least produces a distorted image as if the line pitch was incorrect, plus MPC's interface becomes rather sluggish and takes seconds to react. I've experienced crashes even if I turned off deinterlacing when it was above the crop filter in the list, though... So for the time being, I'm resizing 16:9 DVDs to 856x480 before deinterlacing, as that doesn't resize vertically, but I have to let my graphics card (ATI Radeon X1900 XT) stretch kernel-bobbed 4:3 DVDs to 800x600 which of course isn't great quality-wise. On the other hand, I've found that at least the card's 3:2 pulldown removal kicks in if I change my refresh rate to 48Hz, which is nice - but which only looks good if there aren't any 30 FPS pans/zooms/etc. in the video... So - could you please add resizing after deinterlacing to the bug list? It's possible that it only happens with the kernel deinterlacer, but I haven't checked it that thoroughly yet. I might take a look at the code myself if I can find some time for it, but the last time I looked at the code I was rather lost - is there some documentation somewhere for ffdshow's internals?

No performance increase or fixes for H.264 decoding. But there have been a couple of other bugfixes, so you could post an update.

2ch: http://images.apple.com/movies/fox_a...yes2_h480p.mov 6ch: http://images.apple.com/movies/newli...tlr1_h480p.mov It's easy to recognize if DFX kicked in: it stoles the focus from MPC ... Thanks |

About Deinterlacing(Bob) + Resize:
It's not only this combination being faulty ... also some other filters are affected, if they are placed downstream of "deinterlacing". Effect is that the framerate is doubled by bobbing, but the upfollowing filters take only place every other frame. From memory: "Picture properties", "Levels" and "DeBand" show that misbehaviour. Oh, and it's not exactly a "new" bug ...

The avisynth filter has some special handling for internal framerate doubling, but it's quite possible that the deinterlacing filter doesn't. Hmm. Or even if it does, it looked a little shaky to me anyway. I guess it'll have to get cleaned up.

Second file is reported as 2ch and connects to DFX. I've tryed other files that i have and DFX won't connects to 6ch file decoded by ffdshow. Maybe it's restriction with free unregistered version... |

This issue is not new, there was a time when MediaPlayer Classic's MOV/MP4 splitter could not do this either.... Until it was tweaked For some reason 6Ch AAC streams are stored differently in the MOV container, compared to the .MP4 container.... Cheers

@SeeMoreDigital: you are very kind (as always ), but the problem is not with mov files (try it some avi files) but with ffdshow Of course, there are lots of dsp plugins which don't support 6ch audio, so that's why I have asked this question... So again: is there any way (of course a patch) to support only DFX 6ch audio? Thanks |
