The moderator also confirms that nVidia's drivers do NOT support the Predictive Lossless (rare and most people don't implement) mode of H264. The Studio version (paid) will import H264 on Linux with nVidia graphics card as it uses the nVidia hardware to perform that. I can confirm, the free version of Resolve on Linux does NOT import H264 (as also confirmed in a PM from another user here). the 1080 ti has issues with older drivers (both nouveau and nVidia) and got it running. On a side note, I reinstalled (added some boot options) the Resolve CentOS7 1708 ISO from BM and got it installed last night before going to bed and then installed the latest nVidia drivers. It appears to be "included" in OSX in the "free" version. Instead it appears resolve (on Linux and on Windows) uses the nvidia libraries to decode h264 and pass any licensing (if that exists) on to them. *IF* a paid version of Resolve doesn't "add" x264 support (directly or indirectly via say ffmpeg) and the free version includes same integration (support) of same x264 library (again, directly or indirectly) then resolve should be fine with using it. The licensing on x264 is weird, it is free as long as your have a product that is free (which the free version of Resolve technically is). Lossless h264 is in the standard, just highly unused and so various implementations lack support, that is true! x264 implements that standard and ffmpeg (which is a swiss army knife, a collection of a bunch of codecs in a "semi" standardized interface from a programming interface) as well as a few other "interfaces" (wrappers) around x264 (like libav) also support Lossless as they all use x264. scalable video coding (SVC) would be a similar feature specified in the standard, which will not work in most applications. although it's perfectly standard compliant, it isn't readable by most h.264 codecs. it's a really obscure feature, which is not used much often in real world. gonna go to bed and fight tomorrowĮd Nixon wrote:lossless h.264 encoding is hardly supported by any non ffmpeg based software. CentOS just doesn't support the hardware well out of box and fighting with it is a pain. I just wanted to test importing under CentOS for worked/failed with "lite" version and not having any luck. SO MUCH HARDER installing it on CentOSįrom what I got via PM from another user is that h264 import is only available in the studio version. but getting some missing library when trying to run Resolv on CentOS. so stuck with 3.10 and installed NVIDIA's latest drivers there. Tried to upgrade to some "elrpo" 4.13 kernel and just NOT having any fun there. and the command line from CentOS out of the box (things like control-left/right for skipping blocks of text NOT enabled, sorry I am spoiled with debians/ubuntu's command line ) So downloaded the ISO from CentoOS and tried same thing. tried installing the centos DVD and it crashed once on installer boot, 2nd time installed and a few reboots later wouldn't boot (the chipset on this motherboard are quite new, X299 with 7820X and 1080 Ti). I tried importing an MP4 from a Hero 5 and that didn't work either on my Ubuntu machine here (which IS a more typical MPEG file). The lossless format I believe is standard, just not typical. (ffmpeg is cross platform), many other 'wrappers' around x264 (frameworks, implementations, etc.) that make use of x264 codec (like libav as well) all support lossless. It is a lossless mode for H264 (a somewhat unusual, i-frame only and no quantizing, keep all the data, in a 4:4:4 8-bit mode, so a loss in RGB -> YUV, but lossless in YUV) format.Ī function of the highly used in many places x264 encoder/decoder describes it briefly.įFMPEG uses x264 codec and can be used here. It's not something specific to your Linux setup. WISH ME LUCK!ĭwaine Maggart wrote:Those files don't open in any Resolve version on any platform.
