Can I upload a 490Mb file there?

I found small bug in installer

options untouched


but

isCompMgr=0 is not created in registry [SOFTWARE\GNU\ffdshow] . Result ffdshow shows compatibility manager for any unknown file (for example avs2yuv.exe or x264_x86.exe)

Can I upload a 490Mb file there?

zip your file in 100 mb parts

Yeah, that's what I figured.

@clsid
would it be ok if I upload it on netload instead of mediafire? I have an account there... let me know if that is fine with you, else I'll up it on mediafire...

[Atak_Snajpera]

It does not matter send your sample wherever you want

Uploading now, should be done in an hour or something... my upload speed is...

@clsid and Atak

Let me know if there's any problem.

Hey.
I just tried the same video as djesteban. The latest build (rev3316) really screws the image up - anime movies are basically unwatchable (I also tried build rev 3267, it glitches exactly the same way).

Live action seems ok, tough.

If I revert to build revision 3222, everything is ok.

Let me know if you want screenshots, but it looks exactly the same as what esteban posted.

...I have to say, I've looked at 30 min of live action footage and indeed, I was not able to see any image corruption... so for some odd, crazy reason, that seems to affect primarily anime/animation/cartoon footage (?!?) if that makes any sense... it has too, I mean it was working fine before...

@clsid
Have you been able to check my sample I uploaded? Let me know if you have any question.

Cheers

Patch

Sorry for being so late albain, here are the results of the test with newlibs_beta5:

- Resize with bicubic still produces green video, everything else is fixed.
- Deinterlacing, ffmpeg deinterlacers produce a extremely stuttering image, it doesn't look like a perfomance problem, CPU usage is at ~10% while without deinterlacing is at 20% (1080p H.264 high bitrate). That's with the default YUY2 output, with RGB32 I get a black screen. Yadif and the other deints are good.
- Postprocessing, with mplayer checked and YUY2 output, same behavior as deinterlacing: stuttering. RGB32, black screen. Crashes fixed!
- In Blur, stuttering with YUY2 and black screen with RGB32 again when using mplayer temporal noise reducer, it crashed once with error in libavcodec.
- Luminance level fix, stuttering and black screen with YUY2 and RGB32.

I didn't notice any other problems, all the crashes except that ocasional one are gone. Good work, you're almost there!

I have pinpointed the h264 problem to revision 3256. I will attempt to fix it later.

[albain]

Hi,

here is a new development build with the new ffmpeg scaling/postprocessing libraries.

Fixes : now the DVD subtitles are okay. The fix (committed in previous revision) as well as the new fixes should resolve the last crashing issues that could occur
Bluray subs may be cleaner too

I have also added new functions to the keyboard control : there is now fast forward/rewind commands, and next subtitle stream & next audio stream commands.


Please report back, thanks !

@Stargazer : I don't reproduce the issues you listed in the last build

Great work!

BTW, it will be good to be able to setup "prefered" audio/subtitle track language

[hoborg]

@albain:

Some quick test with your test build:
- open any MKV video in grapstudio (using MPC-HC MKV splitter), play and click on FFDShow icons = crash
- it looks like FFDshow now refuse to accept AAC audio streams
- subtitles color are white (in graphstudio) even if i setup to use yellow
- hitting CTRL+ALT+F4 cause graphstudio crash instead of next subtitle stream
- FFMPEG-MT causing h.264 video stuttering, libavcodec play fine here on IntelAtom CPU.

...do not have time for more test, hope my report will help you.
Thanks again for your work.

EDIT:
here is test file i am working with:

Are you talking about the problem I reported? Jut want to make sure cause you didn't quote :P

If yes, that's awesome, hope it won't be too hard to fix

[sacharja]

#3319 is still crashing while seeking when hardware acceleration is enabled.

Yes, it is the problem you reported.
Fixing will require some trial and error, but should be doable.

Does this mean that when a movie has DTS-HD Master Audio that I can write it to file when connecting ffdshow audio encoder to the Filewriter filter (with PassthroughDTSHD set to 1 in registry) or do I need special hardware for it to work?

Nobody to answer my question above?

Testing is done as always, clean install of ffdshow with everything default, then activating each filter at a time. The results of beta 6 are the same as beta 5. I can reproduce them with all renderers, codecs, etc. so I don't know why you can't.

BTW, the issue with that white shadow in the DVD subs that I uploaded earlier is still there, but I don't know if that's supposed to be fixed in this beta.

Oh and thanks for the new keyboard control features, they're very useful.

This should work as always : in file mode there is a different behaviour for writing the content of the input stream instead of encapsulating it in bitstream format.

However this does not apply to TrueHD : there is special code for this format. So in the TODO list

[TFM_TheMask]

Ok, looking forward to it.
