pub fn install_log_bridge()Expand description
Route FFmpeg’s internal diagnostics into the log facade under the ffmpeg
target, instead of letting them go to stderr.
Idempotent and safe to call from any thread: FFmpeg holds a single global
callback pointer, and repeat calls do nothing.
ensure_initialized already calls this, so most
callers never need to.
This changes process-global FFmpeg state. An application that wants
FFmpeg’s messages on stderr should not call ensure_initialized (or should
install its own callback afterwards).
