    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

    This works very well in VLC, for example. However, Windows Media Player or Samsung TV does not play it. Windows Explorer does not even show a video thumbnail, so the video file is broken by Windows.

    Is not FFmpeg able to produce a standard MPEG4 file, or what the hell is this about ? I’ve tried all the alternatives presented, such as "-fflags +genpts", "-fflags genpts", "-movflags faststart", "-movflags +faststart", "pix_fmt=yuv420p" etc. but nothing worked.

    The sound I copied directly.

  • Encoding 4K 60Hz lossless from a capture card

    13 décembre 2017, par Alex Pizzi

    Windows 10 64-bit
    Ryzen 7
    GTX 1080
    32GB RAM

    Hi all,

    I’m trying to encode 4K 30/60Hz video in a lossless format from a 4K capture card and everything I’ve tried gives me a similar error as in the linked image, [real-time buffer too full or near too full frame dropped]

    [Not mine]
    https://cloud.githubusercontent.com/assets/4932401/22171307/ef5c9864-df58-11e6-8821-4b74ce3f32d0.png

    This is the command I’ve tried most recently :

    ffmpeg.exe -f dshow -video_size 3840x2160 -framerate 30 -pixel_format bgr24 -rtbufsize INT_MAX -i video="MZ0380 PCI, Analog 01 Capture" -vf fps=30 out%d.BMP

    With the images dumped to a 10G RAM disk or 850 EVO. I’m doing this to skip the encoding step.

    I get the same error when encoding with h265 lossless and NVENC h265 lossless.

    I need the video to be lossless as it will be used to test hardware h265 encoders.

    Video source is a 4K Blu-ray.

    Any help would be greatly appreciated. Thank you.

    -Alex P
