[QUOTE="MrGrymReaper, post: 1252465, member: 96700"] Hi, I was wondering whether the TV Server supports hardware accelerated encoding which combined with the changes coming in version 1.21. Could help improve the speed, quality and reliability of recordings? All that would be required is to check if hardware accelerated encoding is supported for the required graphics card and other requirements. Including based on the codec (quality level). Then cause it to dynamically send different switches to the command line ffmpeg which as of 4.02 (latest 4.1) supports hardware encoding. So for Nvidia's NVENC and ffmpeg this could be helpful: [URL='https://developer.nvidia.com/ffmpeg']FFmpeg / libav[/URL]. For all other hardware encoders: [URL='https://trac.ffmpeg.org/wiki/HWAccelIntro']HWAccelIntro – FFmpeg[/URL] The reason being I have in the past had problems with the picture quality and/or synchronisation of audio to video. Even then my graphics card always supported the possibility of hardware encoding. So if this could be present it really could help to reduce issues with problems like this and make the program more efficient. As well as with what ever has driven the changes to the encoding process for version 1.21. [/QUOTE]
