"input": "dvb://...", "jitter": "15ms" A "better" install is not just about uptime; it's about throughput. CPU Affinity for DVB Cards If you have multiple DVB tuners, pin each to a specific CPU core to avoid cache thrashing.
Implement the steps in this guide. Your streams will be more stable. Your CPU usage will drop by 20-30%. And you will finally have an Astra server that you can trust to run for six months without a restart. astra cesbo install better
sudo setcap 'cap_net_admin,cap_net_raw,cap_sys_nice+ep' /usr/bin/astra Run the service as the astra user. Edit /etc/systemd/system/astra.service :
sudo mkfs.xfs -f -l size=128m -d agcount=4 /dev/sdX Mount with noatime,nodiratime,largeio,inode64 for maximum throughput. Let’s move beyond wget and bash . A better install is deterministic, auditable, and repeatable. Step 1: OS Preparation Run these commands before you touch Astra: /etc/astra/astra
You don't have to.
# Find your device (e.g., /dev/dvb/adapter0) # Set affinity for the Astra process running this adapter taskset -cp 2 $(pidof astra) For a 4-adapter system, assign core 0 to adapter 0, core 1 to adapter 1, etc. If you use --transcode , the default software encoder is slow. Force vaapi (Intel) or nvdec (NVIDIA): Your streams will be more stable
astra --transcode "input.ts" --encoder vaapi_h264 --bitrate 4000 Avoid transcoding if possible. Use --copy for codecs. Transcoding should be a last resort; offload it to a dedicated GPU node. Memory HugePages Astra performs better with 2MB HugePages for packet buffers.
