Divx Plus HD - Help needed

[Appu]

Hello,

I have a stream with H.264 Video in an MKV container. Is there any way to find out that this is a Divx Plus HD ( Encoded by Divx Encoders ) stream by looking at any of the parameters in the MKV container fomat?

Any help is appreciated.

regards,
Appu.

MediaInfo should tell you which encoder was used.

Thanks for the reply. MediaInfo is not providing this info.
MediaInfo output is attached.

Have a look here:

At the bottom of the page, there are some DivX Plus HD Video samples in a Matroska container. I downloaded the Iron Man 2 trailer, for which MediaInfo gives the following output:

It seems the only information indicative (alas, not conclusive) of DivX Plus HD Video are the "Writing application" and "Writing library" lines and their corresponding values. If I am not mistaken, these show that only the multiplexing was done with DivX Inc-related tools, not the actual encoding of the video stream. Still, pretty good indication nonetheless...

DivX encoder is actually MainConcept encoder.

Thanks for the info mates.

I am looking for a more concrete information like FourCC in AVI container.

My requirement is to prevent decoding of all Divx Streams.

Older DIvX ( Divx3.11, 4, 5, and 6) comes in AVI container and I can check the FourCC parameters to detect whether it is Divx or not. I am looking for something similar in MKV for Divx HD Plus.
