2. Implementation Principle​

  1. Core component: gmrender-resurrect is a tool that receives DLNA service content and plays it via GStreamer, and can be directly configured as a DLNA client.

  2. Hardware acceleration basis: GStreamer hardware-accelerated video playback has been implemented in advance, meeting the needs of HD stream decoding.

  3. Bilibili screen cast adaptation: When Bilibili casts via DLNA, it sends an H264 stream packaged in FLV (similar to a live stream), which can be played directly with hardware acceleration via gmrender-resurrect.
