vpxenc crashes with VP8

[aseguralasa]

The latest Mediacoder 0.8.28.5580 added VP9 support and now encoding to VP8 crashes vpxenc.

VP9 works, on the other hand, but it is ultra-slow and unusable (Google's fault I guess), around 1 fps for SD and not producing better quality than H.264.

I've tested VP9 encoding and vpxenc didn't crash on my end.
To improve the VP9 encoding speed, you can enable MediaCoder's SVE (Segmental Video Encoding).

Sorry for mentioning both VP8 and VP9 in the post which may be confusing.

The one now that crashes is VP8 encoding, the old one. After the vpxenc crash, MediaCoder is like frozen, it does not detect the crash, and has to be restarted.

I assume both use vpxenc.exe, with VP9 working (though slooooowly) and VP8 crashing.

Thank you anyway for including these codecs!

I rebuilt the vpxenc.exe. Please try updating to 5582 (with full installer).

Hi stanley, I am on MediaCoder build 5602 and am having the same issue with VP8. I have tried on x86 and x64 versions and both throw the same error when trying to use VP8. In addition, my VP9 is not generating a webm format (files are empty). That is a side note though and may just be my inexperience with VP9.

For settings, here is my exported preset I am using to try and generate a webm video:

Please use the latest version.

I use the latest version, but it's still crashing. I can't convert a H264-video to VP8.

Hello there,

can we please get some support? It's still crashing.

I tested with 5645 and VP8 encoding does not crash on my end. Please understand I am not able to fix issue that is not re-producable on my end.
I suggest you performing a un-installation (to make sure older encoder is removed) and perform a clean install.
