There is a bug in Haali splitter (or rather a support to be added) : the PGS subtitles don't have any media subtype in the output pin of Haali's. Don't tried with MPC matroska splitter

TODO/TOFIX :
- Bilinear scaling in RGB mode (only bluray subs may use this scaler)
- Bluray subtitles support from file (.sup)

How will this work if mkvmerge cannot mux sups into mkvs?

I see that ffdshow video has hotkeys available....ffdshow audio does not? is there anyway whatsoever to set hotkeys on the volume filter?

I use Kernel Streaming in S/PDIF w/ headphones on this thing:

I can't control volume at all, and KMixer is unbearable on XP...bummer #_#

I've also looked for winamp/VST plugins that would allow hotkeys for volume control...but no luck.

Hi Xorp, I'm a big fan!

I think MakeMKV can mux .sup into mkvs,

hopefully mkvmerge will add support in the future, now that there is a filter that can play this format properly.

also, albain pointed out that with some development, you could just put the .sup file in the movie directory, without need to mux.

leeperry,
you should look into automation software like girder.

and what would that do for me? I would need two hotkeys in ffdshow audio to play w/ the attenuation of the "volume" filter...I think I'm SOL

isn't there a way through some DLL call or registry entry to do that? because I'm good w/ assigning hotkeys/actions to my Griffin Powermate

tal.aloni · 26th February 2010, 07:57

leeperry, it would be smarter to control the master volume.
I'm sure a device that was designed to look like a knob can somehow do that, (and if it doesn't, and you can surely do that with girder's help).

I try ffdshow rev 3287 and video crash at each time subtitles must be displayed. There is the same problem like with 3285
https://sourceforge.net/tracker/?fun...41&atid=867360

tal.aloni · 26th February 2010, 10:45

yes, the crash happen because YV12 is not supported right now by one of the scaler methods.

albain is working on it.

Although in ffdshow I ony check YUY 2 and not YV12.
Although with RGB 32 it works partially.
If I turn on subtitles from the start of the sample, video crash. If I turn on after the first subtitle, video doesn't crash.

I try with another blu-ray movies and It crash at each time even with rgb32

update: I don't use dxva

ikarad · 26th February 2010, 11:37

With RGB 32, There are some problems with subtitles.
1) Some subtitles appears with a time delay after the voice.

example, this subtitle appears with 1-2 seconds later
124
00:08:27,381 --> 00:08:28,590
Passing through the scorching sunshine
Storyvoards and Settings vy: Shinji Higuchi

I give you subtitle file extracted from bluray
http://www.zshare.net/info.html?7305...92066e73874fde

2) some subtitles are cut
example in this screen: the last word is cut

no windows master volume over S/PDIF.

are you doing realtime encoding to S/PDIF? why can't you use the receiver to control the volume?

I've plugged my headphones directly to the 2 boxes you're seeing...besides I don't like analog volume attenuation, as it increases distortion/kills the stereo balance on stepless pots...and stepped pots are just very inaccurate: http://www.bursonaudio.com/hp_volume_control.htm

I'm outputting bit-perfect stereo PCM over KS in S/PDIF...and no windows volume works at all. anyway, I will look for other solutions now

Shark007 · 26th February 2010, 14:52

To control the volume from the PC rather than from the amplifier when using spdif digital output, go to the 'Control Panel | Sound' applet and double click the spdif output device. Go to the Advanced tab and uncheck the two Exclusive Mode boxes.

fastplayer · 26th February 2010, 21:21

@clsid:
In rev3289 you changed the tool tip text for decoding threads to "Only for ffmpeg-mt H.264 and libavcodec MPEG-1/2 decoder". What does this mean now when using libavcodec for H.264 decoding?

clsid · 26th February 2010, 22:08

libavcodec will use only 1 thread for H.264. The MT patch that we used for libavcodec no longer works properly and was removed a while ago.

For multi-threaded H.264 decoding you should select ffmpeg-mt.

This is funny.... all over the internet audio fanatics are espousing analog volume control over digital for the same reasons !!!

so tell me... how does a resistive voltage divider create distortion? Keep it technical now, no hyperbole... I are an engineer !!

Bear with me because I don't get it.

In MPlayer you can pass "-lavdopts threads=X" as an argument to tell libavcodec how many threads to use for H.264 and MPEG-2 decoding. Has this been removed now in Mplayer or is it because of some limitation in ffdshow? The MT patch was exclusive to ffdshow only, right?

clsid · 26th February 2010, 22:18

@Albain
I noticed your intention to update libswscale. If you or anyone else is going to attempt that, I have some suggestions:
1) Make it part of libavcodec.dll instead of mplayer.dll. That is more natural since libswscale has become part of FFmpeg. They also share code.
2) Try to migrate Haruhiko's custom multi-threaded resizing code.
3) Wait until the current major changes in ffdshow are stable. (DXVA and HD audio bitstreaming)
4) First update our libavcodec with pixfmt updates from FFmpeg. That has been on my ToDo list for a while now.

There are mplayer builds based on ffmpeg-mt too. Plain libavcodec is not multi-threaded for H.264. You can tell it to use X threads, but it won't help increase performance.
