Performance – decoding
Performance varies by codec
Hardware (MPEG-2) decoders (uses very little CPU)
Some reported configurations for software decoding (from HOWTO):
- Athlon 1800XP can decode an 8Mbps stream @ 720x480 using MPEG-2 with 10% CPU utilization
- Athlon 1GHz can decode a 16Mbps stream @ 720x480 using MPEG-2 with 30-50% CPU utilization
- P3-550 can decode a 16Mbps stream @ 480x480 using MPEG-2 with 55% CPU utilization
- Celeron 450 (no SSE) can decode a 16Mbps stream @ 480x480 using MPEG-2 with 80% CPU utilization
