MainConcept SDK Creates Manifest Files for HEVC/H.264 HLS视频
Anyone who’s produced HLS content knows that one of the most complicated tasks is creating the necessary manifest files. 与 HEVC简介 into HTTP 在线直播 (HLS), and mixed codec encoding ladders, this just got tougher. Fortunately for developers who want to stream HEVC/H.264 content to HLS endpoints when this becomes available, MainConcept’s latest codec software development kit (SDK), 版本10.5, can create manifest files in addition to the encoded bitstreams.
新的SDK， which is available now，可输出H.264 in MPEG-2 transport stream or fragmented MP4, and HEVC in the required fragmented MP4 format. Once these files are created, tools within the SDK can create both the variant and master playlists in compliance with Apple’s updated spec.
Commenting on the importance of Apple’s announcement, 托马斯·克莱默, vice president of product management at MainConcept GmbH, 说, "Apple's adding HEVC with AVC into a single HLS package was the missing bridge between the well-established streaming format and the next generation compression technology for Apple devices. What MPEG DASH already supports on other platforms will soon be possible with Apple's updated specification, allowing content providers and delivery networks to produce live and VOD video in one step for legacy as well as latest and future consumer devices.”
Regarding the impetus for supporting manifest file creation, which is a new feature in the MainConcept SDK, 克莱默说, “MainConcept built the tools for software vendors, 制作公司, and CDN providers to add the complete encoding, 包装, and playlist pipeline to their workflows, so our customers don’t have to deal with the details of Apple's specification."
Other noteworthy features of the new SDK include AVC/H.264 6级.0 to 6.2 for higher resolutions and frame rates, unlimited resolution encoding for 360/VR encoding in AVC/H.264 Encoder, and HLG and PQ (including SMPTE 2086 metadata) support for HDR encoding in AVC/H.264.
