Build 0.8.22.5500: H.264 encoder (x64)

[e1wh]

Hi Stanley,
And thanks for MediaCoder!
I think there is a bug with H.264 encoder (0.8.22.5500, x64). I tried to encode a media with it: 3-Pass mode, without audio (only in order to test the promising SVE technology) and the encoder crashes; it crashes only after the first pass with error #14 (if I remember rightly, it worked perfectly with 0.8.21.5399).

Thanks!

When you got this error, was SVE enabled?

Please give a try with 5505.

Hi,
Quick answer!!
So, I've made a try with 5506 (SVE enabled): the encoder now doesn't crash, but there seems to be an issue with the container and the movie obtained at the end.

First row is with .mp4 container, second is .mkv (left: MPC / right: VLC).

The problem remains with .avi, but it is not the same: only the few first seconds are saved.

What about using single-pass with SVE?

[e1wh2]

With SVE and single-pass, .mkv and .mp4 are OK.
But the problem remains with the .avi container.

[e1wh2]

I may add to my last post that .avi works perfectly without SVE.
