The following table describes the information about the source video. Encoding formats H.264 (AVCHD) YUV 4:2:0.The GPU-accelerated instances of Function Compute are based on the Turing architecture and support the following encoding and decoding formats: GPU-accelerated instances can be elastically provisioned based on your business requirements, and are more cost-effective than self-purchased virtual machines (VMs).Įfficiency-prioritized GPU application scenariosįocus on code development and the business objectives without the need to perform the O&M of GPU clusters, such as driver and CUDA version management, machine operation management, and GPU bad card management.įor more information about GPU-accelerated instances, see Instance types and instance modes. GPU-accelerated instances can transcode videos several times faster and push production content to users more efficiently.Ĭost-prioritized GPU application scenarios Real-time and quasi-real-time application scenarios This section describes the benefits of GPU-accelerated instances compared with the instances that are not accelerated by GPUs in Function Compute: An ideal video transcoding solution must be cost-effective in terms of cost (RMB/stream) and power efficiency (watts/stream). Video transcoding is a key step in video production and distribution. In most cases, video platforms must transcode a source video content to output multiple distribution video formats in a 1:N manner based on factors such as bitrate, resolution, channel patch, and playback platform to provide viewers on different playback platforms with different network qualities. With the emergence of highly interactive application scenarios, such as social live streaming, online classroom, and telemedicine, real-time and quasi-real-time Internet traffic is becoming the trend. In this topic, Python is used as an example.

This topic describes how to use Serverless Devs and function code to transcode a video from. You can experience the best practices of GPU-accelerated instances by using the Function Compute console, SDKs, or Serverless Devs.
