    Outside MP, GraphStudioNext didn't build automatically the graph while manually it's working, this is really weird !!

    I'm pretty sure something need a tweak on lav side but the logic of codec works on MPC-HC so this is strange :(

    Ok, I was able to make a workaround, code is based on my fork, because I didn't update lately, I'm on 1.26 Pre :)
    So the patch is also attached :)

    eew, that seems like quite a hack...
    Not sure if I want to be responsible for this code :)
    But on the other hand, I don't expect an answer from nevcariel on this....

    It can depend, long time I didn't report such issue :) but will see it can be open to do something, for sure, I'm pretty sure MPC-HC use some kind of hack :) to manually connect filter between them if an auto rendering failed somehow :)

    A proper patch will be to try to find current video decoder in graph through all codec set in settings, I think the patch is pretty safe, because if auto rendering failed, it tries the manual one and if it failed again we are in original situation LOL :)

    For sure, maybe a better dev can do something better :) :) :)

    Don't get me wrong
    Hey :) I'm not angry or something lol, but you are a better dev than me :D so you can maybe be doing a proper way :)
    What I have thinking is maybe to try to connect the pin output to any input pin from the directshow graph, but doing that, maybe if we have different video code in graph, it not only connect to the one set in MP config ;)

    I think I'm going to wait a bit more, see if my post at doom9 gets any attention before making changes like this (it's not really a showstopper for me)
    And if that doesn't work out I'll have a good thinking about it.

    It's very strange, but you can see that it happens. The logic of NSIS is a complete mystery. :)

    Updated one of my MP installations (from 1.15) to 1.24 Final recently. It went perfectly smoothly, and fixed a few problems I had been having with video playback. Updated my plugins and Streamed MP skin, and not a single issue. Thank you for all your hard work.
