Selur's Little Message Board

Hello Mr. Selur, I have seen that the information of the B-Frames does not appear in the encode log, before the B-Frames did

slds

Strange, normally everything that starts with 'x264 [info]' should end up in the log, will look at it this evening.

Cu Selur

Had a quick look.
x264 only reports the 'x264 [info]: consecutive B-frames: ...'-line if the 'adaptive b-frame decision' (--b-adapt) is enabled.
If x264 does report the line, Hybrid also reports it:

In previous updates, the B-Frames were enabled by default. How can I reactivate the B-Frames? Because I don't know how to do it

thank you sir selur

I have the parameters in Hybrid like this

I had an old version saved and when installing it without touching any parameters, the B-Frames appear

Oh, I thought it was about x264. Smile

Just noticed you are speaking of x265. Smile

Seems like current x265 version do not report that info anymore.
Using the command line I don't get this info any more.

Cu Selur

Hello Mr. Selur, could you include or fix the information on

x265 [info]: consecutive B-frames

thanks and slds Wink

No, if current x265 versions do not provide the information, I can not magically make it appear again.
That would require to change the x265 source code.

Cu Selur

Ok thanks Mr. Selur I didn't know it was from the source code. Big Grin
