Hi,

Is there a tool that can check if an x.264 encoded stream has been encoded with weightp 0, 1 or 2? Preferably within an m2ts container.

Thanks

H.264, not x.264

It's easy - only x264 could encode using weightp (as far as I know) and it writes this kind of info inside the metadata of the video stream. Just check with MediaInfo.

Encoding settings : **** things you're not interested in**** / wpredp=1 / **** more stuff you're not interested in **** if this info is missing then it's most probably encoded using an older version, that doesn't have weightp

A retail BD/hdtv broadcast most probably wouldn't be encoded with x264, so they can't use weightp - no need to check a .m2ts / .ts file.

Didn't know that. Thanks for the info.

Avinaptic shows whether "Weighted Prediction" is used in a H.264 stream. I think that info is encoder-independent. It's in the "PPS id" section.
