In SS/XS, we use FFMPEG as an example. However, when converting wmv and ASF, the image is often displayed on the screen. I checked the information on the Internet and found that the parameter adjustment was invalid.
Later, I used mencoder, and the conversion was slow, but the quality was good. I tried at least a dozen WMV/ASF screens, unexpectedly, the converted FLV file is smaller than that transferred fro
ASF is(Advanced Streaming Format)Microsoft developed for Windows 98.File format. This word can be used with WMA and WMV.
ASF is an open standard that relies on multiple protocols to support data transmission in multiple network environments. SameLike jpg and MPG files, ASF files are also a file type, but they are designed to transfer Synchronized Multimedia Data

A configuration is a set of description data of an ASF configuration. One setting must contain at least one stream configuration setting.
Stream informationThe stream information in the settings includes the bit rate, buffer window, and media attribute settings of the stream. The stream information of video and audio accurately describes the media configurations in the file, including the encoding and decoder used for compressing data (if any

DaVinci is a DSP and arm dual-core architecture of the SOC chip. The interaction between the chip and the outside is managed via arm-side MontaVista Linux and related drivers and applications, and the DSP end only deals with codec-related algorithms. The communication and interaction between DSP and arm is done through the engine (Engine) and the servers (server).1. Codec engine (
Video is an important part of Multimedia Systems in computers. To meet the needs of video storage, people have set different video file formats to put the video and audio in one file for simultaneous playback. Video files are actually a container that contains different tracks. The Container formats used are related to the scalability of video files.
