In about:support I see GPU accelerated Windows: 2/2 Direct3D 9 (OMTC) Supports HW H264 decoding Z: No: Failed to create H264 decoder

Driver version 327.23, video card Nvidia GT 610.

Here's my question. Does HW decoding of H264 work under any circumstances in XP? Or did Firefox decide not to implement it?

Thanks for any info

Good afternoon,

here is the technical support Mozilla's Firefox, not technical support Windows or graphics card. With this question, contact technical support for Windows. Thank you for understanding.

Best regards, David Walczysko Volunteer supporter

I don't think that H.264 and MP4 support on Windows XP is available. On XP you need to use WebM. For H.264 you would need a plugin like VLC.
