    some MP4s don't play in WMP


    Hi. I have a CCTV MP$ it will not play with WMP but does with others like VLC. It is 1920 x 1080 60hz as reported on my CCTV system. should change the resolution or is there another way?

    I tried to attach the jpg but it keeps failing so it is here

    You probably need some codecs (audio/video coders/decoders) to play your video in Windows Media Player or other software. VLC has its own embedded codecs so it can play it without installing external codecs. The best codec collection than plays everything is K-Lite codecs found here: K-Lite Codec Pack 17.6.6 Free Download The standard pack should be OK, but I always prefer the Mega pack to have all codecs, Media Player Classic and more stuff.

    Okay. I downloded the codec. It runs fine now. Does it link into WMP or does WMP look for compatable softare on the PC?

    Your screenshot shows the video is encoded using x265, a fairly recent highly-compressed HEVC format. which WMP doesn't understand by default.

    IMO you have two options:

    1. Use the 'Video Encoding' dropdown shown in your screenshot to see if you can use the slightly older x264 format which is still compressed but uses the older AVC format that WMP understands.

    2. Alternatively, add the HEVC codecs to Windows 10. The HEVC codecs are no longer available for free on the Microsoft Store; they now cost 0.79/$0.99.

    (HEVC codecs were also available for free as APPX packages from free-codecs.com but I notice the download links have now been removed due to a DMCA complaint.

    I haven't found an alternative download location for the latest (24 Jan 2023) APPX installs:

    Microsoft.HEVCVideoExtension_2.0.61591.0_x64__8wekyb3d8bbwe.appx - 64-bit
    Microsoft.HEVCVideoExtension_2.0.61591.0_x32__8wekyb3d8bbwe.appx - 32-bit

    As a result I'll have to rely on the slightly earlier (19 Jan 2023) versions I downloaded:

    Microsoft.HEVCVideoExtension_2.0.53348.0_x64__8wekyb3d8bbwe.appx
    Microsoft.HEVCVideoExtension_2.0.53348.0_x32__8wekyb3d8bbwe.appx

    These are still very much newer than the HEVC extensions available from the MS store which, if you scroll down to the product info, appear to be from 2018.)

    Hope this helps...

    I would use VLC, Microsoft has not kept up on Zume or WMP.

    VLC pretty much plays ANYTHING that you throw at it.

    A free way to watch h.265 videos is installing the x265vfw codec: x265vfw 3.50 Free Download - VideoHelp
    This is included in K-Lite vodev pack, see me previous post.
