    best codec for playing large video files >4096 pixel on pc

    by janine » Fri Sep 07, 2018 1:44 pm

    Hello madmapper fellows,

    I am quite new on PC and i am trying to play video files which are larger than 4096 pixel with hardware acceleration.
    Perhaps this is a stupid question, but i could not find an answer at the forum ...

    Without hardware acceleration h264 encoded mp4 files are playing.
    If I want to play the same h264 file with hardware acceleration i get a black output.
    I know that h264 has a limit at 4K, but most playback programs can deal with larger files.

    A HAP encoded mov file is playing but with poor performance about 1 frame every 5 seconds ...
    Same with a h265 encoded mp4 file.

    So my question is: what is the best codec and container for movies which are larger than 4096 pixel with hardware acceleration on a pc.

    My system has the following specs:
    Windows 10
    Nvidia card GTX 1060 with 6GB Ram

    Perhaps some has a hint for me.
    Thanks in advance !

    All the best,
    janine

    We're working on HAP hardware decoding on Windows. If you want to beta test, please PM me. That will for sure be the best option on Windows. You can also use h264 and activate the "Use hardware acceleration" option, it will use DXVA (DirectX Video Acceleration) so the GPU (graphics card) will decompress the video instead of the CPU.

    Hello mad-matt,

    Thank you for the answer !
    HAP is not an option for me, because i have not the time to reencode all my material.
    I am trying now to play my >4096 h264 files without hardware acceleration on a faster machine ;-)
    Just to be complete a h264 with >4096 pixel width does not play with hardware acceleration on win 10 machine. (output is black)
    Works fine with smaller files. There seems to be a limit with the DXVA component ...

    Looking forward to the next version. Then i will encode everything with HAP.

    All the best,
    janine

    Hi
    I've only just learned that MM on windows doesn't support GPU decoding for HAP. Given that it's kind of the purpose of this codec, I'm puzzled. Is there an ETA on full hap gpu support?

    Hi,
    We're about to release MadMapper 3.6 with HAP HW decoding on Windows. I PM you a beta version. It look quite stable yet.
    Cheers

    Is Hap the best to use (not using MM at moment). File sizes are HUGE, even for 30 second clips.
