However, throughput will be significantly impacted by its' low power profile limit (70W?) as you add more transcode jobs. This is an issue I've observed in production with a similar GPU profile, the Tesla T4. You may consider tuning these encoder presets to compensate for throughput drops with multiple simultaneous transcode sessions, if real time encoding is a priority to you. And on NVDEC: VRAM usage can also be quite steep with multiple sessions. Monitor that carefully via nvidia-smi as you add more transcode jobs. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
