ffdshow tryouts project: Discussion & Development

[THX-UltraII]

what output (for sound) renderer is recommended when you bitstream with the 5xxx series? directsound or the MPC audio renderer? (or another maybe?)

Which player are you using ?

Well, it is not about the player. This feature will alow switch betwen multiple subtitles/audio tracks undepended on player.

For example i use FFDShow on my HTPC based on GB-PVR. There is no support for any track selection in this software, it simply ask DirectShow to play video (like GraphStudio).

But i can map any keyboard shortcut on my remote-so such feture will be perfect solution i think.

Cpu usage is very high, no filters enabled by default over 80-90%. Same file uses no more than 30% with normal ffdshow 3309.
Audio part wouldn't even load. Please create a new branch for all big changes in ffdshow. Thanks for your time!

[albain]

Branching doesn't work well, there are two many files

I gave up last time I tried (for HD audio)

I'll post the patch instead : here it is

I'll move on something else, because here I have no idea why the performances are so low

If someone wants to have a look at it, I think this is better and worth it if we are several to digg into this

libswscale now brings some interesting features (such as alpha scaling)

I don't have any problems with perfomance, it's the same as before. But it's true that ffdshow audio doesn't load with the betas. I didn't mention it because I was testing the filters, but it's there.

- Resize is almost fixed! Bicubic produces green video, but everything else is working!
- ffmpeg deinterlacers like 5-tap lowpass, crash.
- Postprocessing, crash.
- Sharpen, everything works now!
- In Blur, libav error when using mplayer temporal noise reducer.
- Luminance level fix in Picture properties, libav crash.

I asked this because some software implement this feature : MPC, media center+media control, media portal...

This should not be very complicated to do inside FFDSHow, the remote control API already holds the methods, this is just the GUI part which is missing


@Stargazer : thanks again for testing
I tested only the resize filter deeply, otherwise the other filters use the scaler but in a basic mode. This is rather libpostproc (which has also been updated) is used. However I didn't experience any crash with those. I'll make some deeper tests tomorrow if I have some time

Sounds promising

I don't have this issue with 'newlibs_beta4.exe', please try to identify the component responsible.

Like I said I only have the postprocessing crash with some videos, even with all the options forced, which is interesting to say the least. I'll test the new betas.

BTW, if someone is interested I've been compiling my own builds with this patch, which basically reverts r2976 since I've never faced such a situation and seeking is a lot faster with it reverted: http://www.mediafire.com/?ik2diohummm

maybe you could provide debug treces or minidumps? and a sample that albain could use?

[DigitalDeviant]

Sorry to report I have no change in Blu-ray subtitle positioning. The sample still fails to position the second line at the bottom. DVD subtitles still look ugly as well.

[FreeFall]

First I would like to thank albain and all the other people who put their time and energy into working on these projects, your efforts are much appreciated.

Blu-Ray & IDX/SUB Subtitles

with DXVA disabled turning on subtitles crashes with swscaler gaussien (fault libavcodec.dll), other methods work without crashing.

Blu-Ray Disc Sword Of The Stranger (Anime)

wrong subtitle colours and cleanup needed (broken pixel lines above text), coloured subtitles should be blue.

YV12 & YUY2 output subs are orange, RGB output subs are yellow.

My System Setup:

Zoom Player Home Max 7.10 Alpha 3 EVR renderer Vista Business x32
Haali Matroska splitter
Gabest Mpeg Splitter
FFDshow 3309 20100308 dbt newlibs beta4


FreeFall

[albain]

I have fixed the crashes.

Now I am looking at issues with bluray subs

[albain]

Here is a new build with the fixes

Nothing done on subtitles side : still issues with semi-transparent subtitles in YUV mode and sometimes some outline of the subtitle box that appears.

Patch

[XhmikosR]

r3310 x64 ffmpeg compilation is broken:

[STaRGaZeR]

I'll test the lastest beta tomorrow, I don't have time right now.

[TinTime]

Hi,

I've been experimenting with ffdshow to resize and convert to RGB during playback with very positive results so far.

However I've run into a problem with resizing. I'm using:
Resize to screen resolution
Process pixel aspect ratio internally
Keep original aspect ratio
Bilinear resize

I've also set the borders to a medium grey to prevent screen burn.

The problem is that before adding the borders it seems to pad the image to (at a guess) mod16 with black pixels. This leads to a black line down the right hand side of the image. Strangely though this black line disappears if I turn on the OSD. See the images below. They're not the same frame but it should show what I mean.

OSD off
OSD on

This seems to happen with all versions I've tried over the past day, including revision 3309.

Is this a bug or is there a setting somewhere I'm unaware of?

Thanks very much.

TinTime, guys,
how does one change the color of the blavk bars?
