    avc1 codec for Win10

    Hi,

    I've been successfully converting MediaSack .avi files with DVDFab 12 with its H264 codec converter (to .mp4 for Samsung Galaxy Tab S4). The converted files play nicely with Windows Media Player, and with my preferred video player, PowerDVD 22. I've just started using Unifab (2.0.1.8 - 2.0.2.1 fails to download for me at the moment), and I find using the same settings as DVDFab, the H264 converted .mp4 file no longer plays with either of the above. Windows Media Player reports that it is missing an avc1 codec. I'm finding a source for the avc1 codec a bit elusive - there's lots for the av1 codec, though, and my only attempt to install an avc1 codec probably installed the av1 codec! (Note: If I try a generic mp4 converter with MPEG4 codec in Unifab, the quality of the output leaves something to be desired.)

    So, if anyone can point me to a reliable souce of the avc1 codec for Win10 I would definitely appreciate it.

    Thanks in advance, Paul.

    found this -
    • Install the AVC1 codec: You can download and install the K-Lite Codec Pack, which includes the AVC1 codec. This pack is a popular and reliable solution for Windows Media Player codec issues.

      Thank you for your advice, october262, and my apologies for not responding sooner. I have downloaded and installed the latest (as of this am) K-Lite Basic Codec Pack, but I still get the same error from Windows Media Player. Do I need a more extensive version?

        I decided to install the K-Lite Mega Codec Pack to see if this sorts out my problem - sadly, no such luck! Even K-Lite's Media Player Classic fails! Note: I am now using Unifab v2.0.2.1 and am still getting the problem.

        Thinking, perhaps, that the new K-Lite pack might improve the Unifab conversion's compatibility, I regenerated some test files with different format settings, and tried to play them with different video players. I found:

        1. Selecting any Samsung Galaxy device (S4, S7, Tab Pro) has only H.264 (same as source) as the video codec option, and the .mp4 file is unplayable by all 8 of the video players (including such good stand-bys as VLC Media Player, GOM Player & Windows Media Player).
        2. Selecting a generic MP4-Full HD 1920x1080 format offers 4 codec options. Selecting H.264 (same as source) allowed me to play the converted file with GOM Player, K-Lite's MPC-HC, SMPlayer Media Player, and Windows Media Player.
        3. As for 2, but selecting the MPEG4 codec, all my 8 players work (the others not listed so far are: Films & TV, Media Player, VLC Media Player, and Power DVD 22).

        There seems to be something not right with Unifab's H.264 convert codec. It was all right in DVDFab 12 (including for Samsung Galaxy devices), so what's changed/broken?

        Paul.

          Well, as no one seems to be able to point me to a reliable source of the avc1 codec (not av1) for Win10, I'm left with checking future releases of Unifab to see whether the developers have improved the conversion codec. In the interim, I think I will stick with my DVDFab 12 converter - I know it works 100% of the time with its H.264 converter. To say the least, it's rather disappointing.

          Paul.
