mp4 with avisynth using directshow

Okay this sucks for me. I use to be able to create an AVI script to open MP4 compressed files and play them in Virtual dub or Windows Media Player. I recently formatted my PC to start from scratch and now my script doesn't work anymore... I have no idea what is misssing and am angry about it. :angry: My script looked like this: directshowsource("filename.mp4") This is the MP4 file if it helps: - 4MB file If anyone can help me with this crazy issue that would be great. I don't remember installing any other software or codecs to make this work. :thanks:

keep in mind - you must have all decoders/splitters installed

Thanks for your reply Dizmon. I have no idea what that means to have decoders/splitters installed. Where can I get them so to install? Cheers.

Make sure you enable mp4 splitting in haali's, and decoding for whatever format you're using in ffdshow.

I installed ffdshow just now, but receive the same message in Windows Media Player which says: DirectShowSource: Could not open as video or audio. Video returned: "DirectShowSource: couldn't open file VLCP0016.mp4" Cannot play back the file. The format is not supported. Before I erased my machine I don't recall installing fddshow and definitely didn't need to use Haali. The only line in my AVS script was directshowsource("file.mp4") Still no answers.. :(

Yes I know the link to Haali but don't want to have to use it to open MP4 files, I use to be able to do it without Haali and want to know how that was possible. Anyone else help out? Thanks.

@StarCentral Try to play your mp4 with MPC if it plays look for the filter is decoding. Open play dialog and look in filters. If it doesn't play it seems to me that you had in the old instalation some mp4 decoder and you don't remember which. In that case install ffdshow and enable to decode, there are two configuration pages test with both I dont remember exactly which one I hope this can be useful ARDA

I appreciate everyone's reply. I'm not against any particular solution, I just wish I knew how I had it working before : ) So far I've tried installing ffdshow but still can't get it working. It should work with just installing ffdshow right?

also you need to define the framerate with directshowsource

Okay I've got Haali and ffdshow installed. I run my AVS script: directshowsource("d:\SANY0039.MP4",fps=29.97) ...and get "Directshowsource: the filter graph manager won't talk to me". Foxyshadis - I've never installed Nero on this particular PC and now am trying to think of what I might have installed... I usually keep it the same each time I clean it out. I might have installed some cheesy Ulead DVD burning software that came with the camera that creates MP4 files.. could this have been how I had it working in the past without ffdshow and haali? I definitely know I never installed those programs in the past. Anyone know what the graph manager error means? Thx again... and again... and so on... and so on... :)
