The MPEG committee's standard is called DASH (Dynamic Adaptive Streaming over HTTP) and it works by dividing the multimedia stream into segments (with each one having a MPD (media presentation description) holding the important data - URL, resolution, bitrate etc.). Towards this, various adaptive bitrate streaming schemes are used. The quality of video streaming depends heavily on the network characteristics. Before digging further, a short detour to understand the various streaming profiles is necessary. However, the options (such as -prefer_smd and -vcodec h264_smd) indicate that this is a custom build for the DS214play / Evansport platform. We find that Synology triggers ffmpeg for this purpose. The running processes give more insight into how hardware transcoding is utilized. Note that transcoding a 1080p VC-1 clip to 1080p H.264 consumes less than 20% CPU resources. Interesting aspects are pointed out in the above screen capture. To prove that hardware transcoding works, we have a screenshot below of the resource usage and running processes on the DS214play taken while playing back a VC1 MKV clip using DLNA on a Sony KDL46EX720 TV. ![]() The important points to note include the fact that folders can be set up for indexing of particular media types only and that video transcoding can be enabled for certain extensions that DLNA DMRs (Digital Media Renderers) don't commonly support (rm, rmvb, mkv). ![]()
