Bitmovin Survey: HLS Still Dominates, but DASH is on the Rise
Video infrastructure provider Bitmovin released its 视频开发者报告2017 今天, which included the results from 380 survey respondents from major streaming properties around the world, 包括广播电视, 出版商, OTT流媒体服务, 以及在线视频平台. The survey included a range of questions about current encoding and distribution practices, from codec usage to the biggest problems experienced in their distribution practices.
对于一些问题, 像格式和编解码器的使用, the survey asked about current and planned usage, 产生了一些有趣的结果. 例如, 今天, 78%的受访者目前正在使用HLS, 56%的人也使用DASH, 37%的人坚持服用RTMP, primarily for contribution feeds and low-latency use cases like betting. The survey included regional variations for North America, 电磁辐射, 亚太地区, 及拉丁美洲, which showed that North America has the lowest penetration of DASH usage (46%), 相比之下，亚太地区为69%，拉丁美洲为53%.

12个月内, 然而, 31% of respondents predicted that they would start using DASH, which Bitmovin attributed to the ease of working with multiple DRMs. An additional 24% predicted adding HLS, which Bitmovin attributed to Apple's adding HEVC to HLS. The Common Media Application Format (CMAF) was on the 12-month radar screen of 19% of respondents, presumably in the hopes of creating a single set of files they can distribute to DASH and HLS.
Regarding codec usage, 95% of respondents deploy H.264, which is no surprise, though 28% also use HEVC, and 10% VP9, and 6% were experimenting with AV1. 12个月内, 超过40%的受访者计划增加HEVC, 18%的人计划添加VP9, 14%的受访者预计将部署AV1. The survey does not divide usage between contribution and distribution, which would have been useful.
The survey also asked about the respondent's encoding practices. 令人惊讶的是, on-premise software dominated with 54% penetration, followed by 46% encoding with hardware appliances, 尽管这主要是针对实时用例的. Thirty-four percent encoded with software in the cloud, while 24% used a cloud encoding service.
Other survey topics included target platforms and video players, 数字版权管理系统, 盈利模式, 音频编解码器, AD技术, 最后一个问题, “What are the biggest problems that you are experiencing with video technology 今天?“一点也不奇怪, 49% indicated that getting playback running on all devices was their biggest problem, while 45% identified “player issues” on main platforms/devices. Next up was CDN problems at 27%, with only 15% identifying ad blockers as a significant problem.
