[Streaming media network] on August 18, Beijing News: Recently, at the Intel solution show held by Intel in Beijing, teavea (Official Website www.teavea.com) released its latest H. 264 preview version of the transcoding software. In a dual-core system, the efficiency is twice that of x264!
Currently, H. 264 format of film and television files are increasingly popular on the Internet, mainly thanks to the many benefits brought by its high compression ratio, such as: the same high-definition movie, MPEG2 ts format usually requires 20-30 GB file size, through H. after 264 compression, it can be reduced to the original 1/10, while the video quality is almost unchanged. This greatly reduces the pressure on network transmission and file storage.
Therefore, how to convert and compress videos into H.264 formats has become a hot topic in the video field. In the current PC version of H.264 encoding software, there are two outstanding ones: Free x264 encoder and paid Nero encoder. For ordinary network video enthusiasts, most of them use the free x264 encoder for video file suppression. H. the 264 encoding tool is fully optimized based on the CPU Instruction Set and provides a higher h than x264. 264 compression efficiency, especially in dual-core mode, teavea media recode compression efficiency is more than one time of x264, which will greatly shorten the compression time and benefit H. 264 code is further popularized.
Compare the time required to compress the same video source file for teavea media recode and x264:
Test environment:
Compressed source file: 522 mb. AVI file (653 kbps 480*272) at 48 hours)
Compression Parameters: 384 kbps, H.264 main profile, consistent resolution and video compression metrics
It can be seen that the compression time of teavea is shortened by 10% compared with x264 on a single-core CPU, and over 1/2 on a dual-core CPU. This will greatly save the time required to encode the H.264 File. In addition to high compression efficiency, teavea media recode is also compatible with various video sources. videos that can be played on the user's local machine can be smoothly compressed into H.264 format.
Teavea also presented an advanced video application on PC in the future. On a dual-core Pentium D processor PC, the dual-path high-definition image is successfully demonstrated, one of which is 1080 p H. 264 video streams, the other is 720 p H. 264 video streams, with a semi-transparent overlay in the image. According to teavea engineers, as the processor performance continues to improve, the combination of HD video decoding on PC desktop and P2P streaming media will become a mainstream trend in the PC multimedia field in the future!
