Symptom
This is in conjunction with the recent EV server beta build version 7.1.8.82570 to improve, in particular, video lag issues with certain Axis firmware versions.
The AVCodec / HW acceleration facilitates the Axis 4k camera (P1428-E) allowing smooth video streaming at max resolution and frame rate.
Despite the beta build, this 4k resolution camera is almost useless without Hardware Acceleration enabled.

Workaround
1) Close any Exacq clients you may have open.
2) Download the file from the following link:
32-bit Windows:
http://ffmpeg.zeranoe.com/builds/win32/shared/ffmpeg-2.5.2-win32-shared.7z
64-bit Windows:
http://ffmpeg.zeranoe.com/builds/win64/shared/ffmpeg-2.5.2-win64-shared.7z
3) Extract the Zip file to a folder on your computer. From that extracted zip file copy the following files to the exacqVision client directory.
Avcodec-56.dll
Avformat-56.dll
Avutil-54.dll
Swresample-1.dll
4) Start your exacqVision client and click on the configuration “gear” icon. Click on client and in the client options you should see a new hardware acceleration option available. Move the slider to the right and enable hardware acceleration.
