Exporting video for upload on Mac

Hello, for a museum installation, I need the possibility to upload recorded video on sftp server. When I am on Windows, I can use h264 nVidia encode, upload it to sftp with pysftp and can see the clip on internet with the ip adress. On mac, I can only use MPEG 4 (part 2) encode and if I upload it, when I try to watch it or download it, I have a MIME type error. Unfortunately we choosed and bought the new mac mini (perfect for all other aspects).
here is the working link

here is the not working link

There is no possibilities to trancode the file because the installation is working all days, recording audience production and uploading it with time tag.
Any help would be appreciated.

I’m able to watch the 2nd link, but not in a web-player. It’s likely the webplayer just doesn’t support that codec. There isn’t a good solution for this right now unfortunately. The new Vulkan Video feature that embed encoding into Vulkan may enable this on macOS in the medium future (late this year), assuming MoltenVK adds support for it.

@malcolm Thank you for your answer. The exhibition will start on october so perhaps it would be possible with Vulkan. For now the solution I found is to use a subprocess with ffmpeg-python to transcode the files to proper mp4. I will test the process:

  • receive information from Arduino (separate TD process with OSC): works
  • real time editing for video, voice over and music: works
  • recording of audio-video mix with movie file out Top by timetagged 30’ part: works
  • transcoding with ffmpeg-python (python subprocess): work in progress
  • sftp uploading with sftplib (python subprocess): works
    A good stress test for the new M1 Mac Mini.
