Question:
How do I get FFDShow in the filter chain when the decoder is disabled?
Details:
I am watching a video encoded as AVC1 using CoreAVC for the decoder. I want to use FFDshow in the filter chain because I like some of the features such as "picture properties", "resize & aspect", etc.
The problem is if I enable H264/VC1 in FFDShow it disables CoreAVC unless I set CoreAVC to "default" in which case it disables FFDShow.
Thanks! |

By setting ffdshow to handle uncompressed video as well? It should get added after the core decoder then?

Hmm, you mean "raw video"? I already have that set to "all supported".
Here's what GraphStudio shows (using LAV splitter and MPC HomeCinema):
source.mkv -> CoreAVC-> VMR9 Renderer |

mpc's a different case, it's doing it's own filtergraph construction
What does it look liike in graphedit when you just drop a file into it?
I don't have core installed any more, but I did used to get both of them in the graph when I wanted to
IIRC it was just a case of matching the output of core to the input of ffdshow
For virtualdub, that all assumes you're using the directshow plugin, as the others do not work in the same way
In those (eg mkv plugin) you have to choose the default codec is used and no others are chained in
In the directshow plugin's file information page you can see the text report of the directshow filter graph used
This may, or may not be of help
I have a slightly modified version of the directshow plugin that has checkboxes in it's options for trying to force the use of ffdshow and/or core

When I drop the file onto GraphStudio, it just hangs. The CoreAVC and LAV Splitter icons show up in the system tray but GraphStudio goes unresponsive.
Thing is I don't care if I use CoreAVC or not, it's just that ffdshow seems to use a crap ton of CPU when decoding AVC1 to the point where the video and audio will go out of sync after a few minutes. |

Virtualdub doesn't care how long a frame takes to decode (or the audio either)
FFDshow (by default) DOES care about how long it's taking to decode and will drop frames if it thinks things are taking too long
In it's options -> decoder options -> drop frames on delay
Untick that
And the 'skip h264 deblocking' if you always want better quality even if it's going slow

Sorry about the delayed response, I recently moved and despite it being the 21st century it took them a while to get my internet working properly.
@dlonranger: I will try what you suggested and report back if still having problems.
Thanks! |
