In what case will x264.exe display eta in title bar?

[jasonwoo]

Hey everyone,

I found sometimes, I encode m2ts file with x264.exe, it will display eta in title bar of command line mode, and other info, suche as current frames/total frames.

But sometimes do not.

So, why would this happen, just because of the different type of source file?

Thanks a lot.

It always displays the progress and ETA, given that the total number of frames is known.

If, for example, you feed x264 with "raw" data from the STDIN, the total number of frames cannot be known - and thus the progress or ETA cannot be calculated.

You can still manually set the total number frames by hand, using the "--frames" option.

(There may be other cases, in which ffms2/lavf input cannot determine the total number of frames beforehand though, but I don't have an exhaustive list)
