subprocess.run() with preexec_fn forces Python to use fork() instead of posix_spawn(). In Frigate's main process (75+ threads), fork() creates a child that inherits locked mutexes from other threads. The child may deadlocks e.g. on a pysqlite3 mutex before it can exec() ffmpeg. Replace preexec_fn=lower_priority (which calls os.nice(19)) with prefixing the ffmpeg command with "nice -n 19", achieving the same priority reduction without requiring preexec_fn. This allows Python to use posix_spawn() which is safe in multithreaded processes. Fixes both the primary export path and the CPU fallback retry path. |
