wmv codec

Recently, I briefly read the Skype SILK codec algorithm. The basic principles and procedures are basically clear. I will take a closer look at the details later. I will give a brief introduction today. SILK Codec is a speech and audio Codec algorithm that provides great flexibility for audio bandwidth, network bandwidth, and algorithm complexity. Four sampling ra

Company Project reason, contact a bit of video stream H264 codec knowledge, before the project using the FFmpeg Multimedia library, using the CPU to do video encoding and decoding, commonly known as soft-coded soft solutions. This method is more common, but it consumes CPU resources, and the codec efficiency is not high. The general system will provide a GPU or a dedicated processor to encode and decode the

Thank the great God to share, although now still do not understand, keep everyone together to seePS: A lot of people don't know how to read "FFmpeg". It reads "EF EF em Peg"0. Background knowledgeThis chapter focuses on where ffmpeg are used (here are just a few of the many I know, in fact much more than this). To illustrate: FFmpeg is very important.Use FFmpeg as the kernel video player: Mplayer,ffplay, shooter player, Storm av, kmplayer,qq av ... Use FFmpeg as the DirectShow Filt

In the CSDN on this period of time, contact with a lot of people in the same industry, especially the use of FFmpeg audio codec, some have many years of experience in the "Great God", some have just started to learn beginners. In the process of discussing with you, I suddenly found a problem: there seems to be an insurmountable gap between the "great God" and the beginner. The "Great God" is highly skilled and explores esoteric issues, while beginners

After multimedia files are parsed, you need to find the appropriate codec according to mime. 2.3 of the system has two methods: SoftwareCodec and omx node codec. The latter can be optimized with special hardware, the former seems to be relatively standard soft decoding.Below is the codeOmxcodec. cppOmxcodec: createVector FindMatchingCodecs (Mime, createEncoder, matchComponentName, flags, matchingCodecs );I

I have summarized the commonly used ITU speech codec for your reference: 1. g.711: pulse code modulation (PCM) of voice Frequencies Encoding type: Expanded PCMEncoding rate: 64 Kbps Theoretical latency: the time for processing a sample (1/8000 seconds = 0.125 milliseconds ); Sound Quality: Long Distance quality;Advantages: Low algorithm complexity, low compression ratio (CD sound quality> 400 Kbps), minimum codec
