We lately covered picture character in our survey of the 1st desktop Brazos micro-ITX board. If you so soon read it, then you know there were approximately surprising consequences when we dug into the platform's picture decode/encode capabilities. Totally else constituting equal, the end product character of encoded video was fairly like in equating Intel and AMD. Nvidia's CUDA-accelerated end product was some other story entirely, though. Any video we pumped by it had discernible blockiness in high-motion scenes. We'd been discouraged about this antecedently, but it took a lot of A-B comparison to understand how bad the situation actually was.
That contributes us to today's picture character tests. There are lots leftover questions from our Brazos coverage, which weren't actually relevant there, but deserved their own in-depth exploration.We demand to cover a elite basic points earlier we dive into the nitty gritty. It is significant to construct the distinction amongst a codec and a file container. For example, Blu-ray massage is often seen with a .m2ts file extension. Still, the BDAV (Blu-ray Disc Audio/Video) container format is essentially a memory wrapper. Three possible codecs can be utilized: MPEG-2, H.264, and VC-1.
So, what is the demand difference amongst a codec and a container? Think about your most recent vacation. Your luggage is the file container, and the type of baggage you select dictates where you put your clothes, bath productions, computer, and so on. The codec (compression decompression) is the mode in which you squash everything (the inormation) down to fit into your luggage. This essentially applies to any multimedia massage.
For example, Microsoft's AVI (Sound Video supply) initialize is a register instrumentation, but it could accept video encoded with a variety of codecs, from DivX to MPEG-ii.When you play something in a video player, usually, the encoded video information passes by the decoder and is spit out as YUV data (color space) and put onto your display. The decoder distinguishes the format and uncompresses the information into useful data that can undergo working and be considered.
