Accelerate HD video playback
Once on my netbook (Acer Aspire One 110) I couldn’t normally watch the video due to the brakes (anime in 720p). After which a trial on the topic followed, how can this be corrected, the result of which is read here.
Virtually all HD video is compressed according to the H.264 standard. Usually for its decoding (and not only it) use ffmpeg . However, its speed may not be enough. So, the fixes found are:
1. Use ffmpeg-mt , fork ffmpeg, which uses multithreading, which can greatly help on multi-core / multiprocessor systems. (by the way, it also helped on Atom in my netbook, which seems to be not very multicore :)).
How to use ffmpeg-mt? I offer two options:
1) Install the mplayer build, which uses exactly ffmpeg-mt (this option is also suitable for linux systems). You can get it here (win32).
2) Put K-Lite Mega Codec Pack , which includes both normal ffmpeg and ffmpeg-mt, and when installing, tick the use of ffmpeg-mt to decode H.264 video (or you can do it later in ffmpeg video settings decoder
')
2. Use the DivX H.264 decoder codec. It is part of the DivX Bundle , and is not open-source. However, it works better. The DivX Bundle installer puts a bunch of extra rubbish, so it's best to install the decoder itself separately (if you dig, you can find it on the K-Lite Codec Pack website, but here it is ).
ADD: The CoreAVC codec, considered the fastest decoder for H.264, was also mentioned in the comments. But, unfortunately, it is paid.
3. Use the Media Player Classic mod, called Homecinema (included in the K-Lite Mega Codec Pack). It has a built-in decoder H.264, which uses hardware acceleration (by means of a video card through the DirectX API). It is called DXVA. Its use can be configured when installing the codec pack, or in the options of the Media Player Classic itself, on the Internal Filters tab.
PS To all owners of netbooks with a slow SSD is dedicated - install FlashPoint , and the speed of work will increase significantly.
