Building on 64bits #32

Closed ghost closed 2 years ago

ghost commented 2 years ago

The official configure script seems to be expecting 32bits only, and is tied to rpi userspace (mmal).

Is it possible to build rpi-ffmpeg on a 64bit system? (Slarm64 if that matters.)

jc-kynesim commented 2 years ago

Try the pi-util/conf_native.sh script from dev/4.4/rpi_import_1 - that definitely works on PiOS 64 (I've just checked) and has options for mmal/no-mmal. I probably haven't backported everything to 4.3.2. The conf_pi* cross-compile scripts have undoubtedly rotted hard but were sort of hanging around as a hint I might want to fix them, but these days native compile is fast enough that it has not been any sort of priority.

Hm.... can't say that upstream ffmpeg plays 4k h265 smoothly.... even if recoded with a -fastdecode profile.

But the code seem to have built fine, even though the prefixes are a bit messed up. I'll close.

If you have h/w (stateless V4L2) H265 decode and direct drm display then its smooth, otherwise not.
