How to get x264 info like this ?

[PrinceSwaraj]

Hi VH ,

How to get x264 information from any video ? Any software ?
Please tell me how to do that !

x264 Information:
x264 [info]: frame I:2007 Avg QP:13.92 size:104933
x264 [info]: frame P:40295 Avg QP:15.20 size: 47924
x264 [info]: frame B:104626 Avg QP:18.24 size: 19366
x264 [info]: consecutive B-frames: 4.7% 5.5% 14.6% 41.1% 14.1% 19.9%

That's basically from an x264 encode log. Not sure if any other tools output info in such way.

AFAIK, only x264 encoder outputs log like that. Also, GUIs that use x264.exe (MeGUI, StaxRip, Simple x264 launcher) capture that info and output it, too.
The thing is, that log can be obtained only if one encodes file himself.

How do I get that info anyway ?

With certain encoders, the encoder will insert that log info into the auxilliary data packets of the video stream, so you can read it with a media viewer/tester such as MediaInfo.

But if the encoder doesn't write that info, you are out of luck (and as mentioned before, not all of them do).

Actually, now that I re-read your OP, I realize you're wanting ANALYSIS of the file. Your best bet there would be using something like Bitrate Viewer, or better, the Tecoltd Bitrate Viewer.
