You should see at least 3 threads running normally when doing a HLS
transcode. The decoding is done in one thread and the code is set to
default to using 2 threads in libx264 for encoding.
If you run something like the following SQL command on your database,
it will bump up the number of threads used for encoding to 4.
INSERT settings (value, data, hostname)
VALUES ('HTTPLiveStreamThreads', '4', 'YOURBACKENDHOSTNAME');
I'll probably make this a setting as part of some other work I'm currently
doing on the HLS encoder.
