ffdshow tryouts project: Discussion & Development - Page 758

It is dead.
The full source is available, so you can make your own debug build.

If you only need a decoder, then LAV Filters is a superior alternative.

I already support both in my software - FFDSHOW and LAV.
Anyway, pity. It was a greate codec project.
BTW any faq/howto about building ffdshow project available (caveats, used compilers&tools, etc)?

You need:
1) Visual Studio 2010
2) MingW.
Extract MinGW to c:\msys
Add c:\msys\bin and c:\msys\mingw\bin to %PATH%
3) DirectX SDK june 2010

I agree with you Clsid, maybe some parts of FFdshow are old and need updates, but the name is a "legend" if you understand me... millions of users use it. Maybe a merge of ffdshow and LAV could make a good choise....

Not going to happen.

I have already made preparations that make it possible to install just the ffdshow processing filters. Optionally loading those into the playback graph after the LAV decoders is on the ToDo list of LAV Filters.

ipanema · 26th April 2013, 11:54

I have been experimenting with using the ffdshow-tryouts encoder (MJPEG selected) and getting some strange results, so I tried using it in a simple Graph Studio filter graph consisting of

File Source Async (Lagarith AVI file 1920x1080) > AVI Splitter > AVI Decompressor > ffdshow video codes > AVI Mux > File writer

effectively this is just transcoding a Lagarith AVI file to an MJPEG compressed AVI file.

The file it produces has the correct imagery, but is EXTREMELY grainy looking. I tried ffdshow video codec and ffdshow video encoder (not sure if they are really the same thing under the hood). Also, strangely, if you delete the ffdshow block and re-insert it and connect the graph up again and run it you either get an output file that has noticeable MJPEG artifacts (as if it was encoded at a much lower quality level than set in the ffdshow properties), or a complete random mess of pixels, or a fatal error "This application has requested the runtime to terminate in an unusual way".

I'm using version 4500 Jan 6 2013.

Is there a known problem with using ffdshow-tryouts as an MJPEG encoder, or am I doing something wrong?

It has been a while since I visited these parts, so am saddend to see that the ffdshow tryouts projects is dead. Where has everyone moved onto? I noticed that LAV decoders are mentioned, and Microsoft are moving from DirectShow to Media Foundation - is LAV using Media Foundation only?

What other other options are there for plug-in encoders if I can't get the ffdshow-tryouts encoder to work?

clsid · 26th April 2013, 14:45

Yes, it is possible it is buggy. That functionality hasn't been actively maintained or tested for a very long time.

There are plenty of alternatives. VFW instead of DirectShow. Or something FFmpeg based, such as Handbrake.

Nice, looking forward to this.

That sounds very useful.

I suppose this will allow us the flexibility of using the player of choice, e.g. for using LAV filters in WMC without external players, while still taking advantage of the upscaling/post-processing/subtitle filters that ffdshow included.

clsid · 29th April 2013, 15:46

It is actually already possible right now to use ffdshow as a post-processor after LAV Video decoder. Benefit of the proposed method is that it allows using a small whitelist, and thus less chance of compatibility issues with other apps.

It is unknown when or if it will be implemented in LAV. So it could take a long time before it is available.

I understand development on this project is inactive, but I have a quick question. Has anyone ever been able to get the Crop/Zoom function to work properly? It seems cropping is uneven no matter if all sides are set to the same value. For example, if horizontal and vertical zoom are set to 1, it'll crop more on the bottom than on the rest of the sides. I tested both Crop and Zoom at different settings using a variety of builds (including last one) with a Spears & Munsil test pattern with no luck.

I use mpc-hc and the PnS Inc Size command isn't very precise (it'll crop too much). Basically, I'd like the ability to crop in smaller increments on the fly and in an even manner. Any ideas?

mandarinka · 13th May 2013, 17:47

IIRC the crop requires rather large increments to be used (4 or even 8?). I suggest using avisynth filtering...

mindbomb · 22nd May 2013, 21:23

question about LFE crossover:
"Remove low frequencies added to LFE from left and right channel" - does this also remove the low frequencies from the center and surround in a 5.1 configuration?

Hi clsid,

Q: What is the last "Stable" version that would work good with Vista?

Thanks,

G!

ryrynz · 26th May 2013, 02:03

Any of them since the last stable release really, current is 4512.

Hi ryrynz,

Thanks! Just out of curisoity ... is this what you are running and what is your OS?

G!

Running Eric Gur's 4512 build found here on Windows 7 x64.

Hey clsid, are there any chances of getting something like on 'directory name match' added to the preset auto conditions? Surely it it be fairly trivial to add this feature?
