杜比视界 Profile 7(UHD 蓝光原盘转封装常见的格式)兼容播放:电视不能按杜比视界解码 Profile 7 时,改为播放它底下的 HDR10 画面,不再无法播放或让服务器转码。电视能直接解码 Profile 7 的,照常按杜比视界播放。 / Dolby Vision profile 7, the one UHD Blu-ray remuxes carry, now plays on televisions that cannot decode it as Dolby Vision: the HDR10 picture underneath is shown instead of the file failing or the server converting it. A set that does decode profile 7 plays it as Dolby Vision as before.
告诉服务器:没有杜比视界的 HDR10 电视也能直接播放带 HDR10 或 SDR 底层的杜比视界文件(Profile 7、8),不必转码。 / The server is told that an HDR10 television without Dolby Vision can take Dolby Vision files with an HDR10 or SDR base layer (profiles 7 and 8) as they are, rather than converting them.
变更 / Changed
杜比(AC3、E-AC3、TrueHD)和 DTS 音频默认由 FFmpeg 解码,不再用电视自带的解码器;能原码输出给功放的照常原码输出。有些电视列着杜比解码器,没有授权时却只放出静音,也不报错。 / Dolby (AC3, E-AC3, TrueHD) and DTS audio are decoded by FFmpeg by default rather than by the TV's own decoder; where it can go to an amplifier untouched, it still does. Some sets list a Dolby decoder that, without a licence, plays silence and reports nothing.
