Is there a tool that can check weather an MPEG4 video stream has got b-frames, gmc, qpel and so on?
I need this because my mpeg4 standalone won't play qpel or xvid GMC (divx gmc he plays fine)

So it means that video has no GMC a/o QPel frames. ;) If it would have it would be displayed there...

What ffdshow version are you using?

Try to encode some sample with Qpel in Xvid a then play it with ffdshow.

i use the current alpha version...
Maybe my Standalone is just nuts and can't play the file because of sth other than QPel

have to encode my own xvid file later on

Can it be set to read info about audio and video streams in an MP4 container. As I've not been able to find a tool that can as yet?

I haven't yet managed to read info from ffdshow.

For now, I use QuickTime Player to view information of the MPEG4 file. Just press Ctrl + J to get the info.

It depends on type of video in MP4 container. If ffdshow is able to decode it via libavcodec and insert itself into DirectShow chain, than yes IMHO.

As McoreD mentioned, QuickTime can provide more detailed info!

It's a real shame the excellent 'Gpot' tool can only read AVI container streams.
