Topic: Hardware streaming on Mac

Hello, I am trying to use the hardware video encoder option on MacOS and get the following error in the transcoder log:
17:21:22.104: [vo/lavc] Opening encoder: VideoToolbox H.264 Encoder [h264_videotoolbox]
17:21:22.260: [ffmpeg] h264_videotoolbox: Error: cannot create compression session: -12915
17:21:22.260: [ffmpeg] h264_videotoolbox: Try -allow_sw 1. The hardware encoder may be busy, or not supported.
17:21:22.260: [vo/lavc] Could not initialize encoder.
17:21:22.260: Could not initialize video chain.

Here is my mpv.conf (very vanilla):
input-ipc-server=/tmp/mpvsocket
hwdec-codecs=all
hwdec=auto-copy
opengl-early-flush=no
hr-seek-framedrop=no

I am using a 6-core Mac-Pro with 2x AMD FirePro D500 3 GB graphics cards and 64GB RAM

Can you help?

Re: Hardware streaming on Mac

Not our fault.

For example there the same error popped out because of incompatible video size (320*240)
