Bright sunshine, gentle wind, two dogs open the window, feel spring has arrived.
“It’s such a nice day to stay home and play on the computer.” Erdogzi said, clicking on the App. The latest version update mentioned support for 4K video playback, which Erdogzi has been waiting for for a long time.
“Today I’m going to see the LURE home in 4K, how good are you…”
Internet speed can’t keep up with two dogs
After all, 4K is worth waiting for, and as the owner of 100 gigabit broadband, he is confident that a pause, go to the refrigerator to get a Coke, is enough to enjoy a long time of happiness.
“All ready, please begin your show.” Two dog son picked up the cola fierce poured a mouthful, knocked the space, the title song has not sung two sentences, and stuck. Next, product such as fell to the ground when the card once, product such as turn around when the card once, product such as slap when the card once, the hen shook his head smiling ready to say you good time card once.
“Stuck!”
4K really does not kui is 4K, two dogs began to study is not high enough computer configuration or network speed is not fast enough.
First of all, the computer configuration, two dogs immediately dispels the question, he can run the HIVE machine, whether the host or the monitor, is no problem with high.
The problem should be in the aspect of network speed, 4K video network speed demand rate is generally between 40Mb/s and 60Mb/s, and erguzi home called 100M broadband, in actual use, the rate can not be stable at 40Mb/s, “jam machine” phenomenon will naturally appear many times.
H.265, half the flow, double the fun
Helpless two dogs can only put the whole set of video download down, found that the video is h.264 coding standard, this how to line, good “home temptation” 4K version, at least use H.265 to code, or this effect with watching “back to the village temptation”.
The village network speed is not developed, the video needs to be pressed. Using H.265 coding method can effectively improve the compression efficiency of video, under the condition of limited bandwidth, the same video viewing quality, H.265 coding technology compared to H.264 coding technology can reduce the video capacity of 39% to 74%. It also achieves better signal-to-noise ratio (PSNR) than H.264 video.
IEEE Publications Circuits and Systems for Video Technology, Comparison of the Coding Efficiency of Video Coding Standards Including High Efficiency Video Coding A test of H.265’s coding performance with nine video clips yielded satisfactory results. Even in the worst-performing sample, the traffic savings were close to 30%, with an average performance of 49.3%.
Narrow band HD, the fun of black technology
Of course, in addition to the H.264 coding into H.265 coding method, you can also use the cloud narrowband HD function to smoothly watch the world’s best products such as seamless wrangling.
Narrowband HD reduces the video size by 30% on average while keeping the video encoding rate constant. The general process is to first input a video transcoding fragment, then conduct complexity analysis, and then divide the scene transcoding parameters, such as slow motion or violent motion. Of course, there will also be a bit rate control algorithm to adjust the output of the encoder, and finally get the encoded video.
Finish, two dogs closed the window, put on the VR hood, “such a good acting, must be immersive to have fun. I want to see product carefully such as failure but helpless appearance.” However, although love strange App support VR mode, but the definition of the picture is not to compliment, product such as clothes are blurred.
“Alas, it seems that after the universal POPULARIZATION of 5G, VR movies can be immersive, then maybe 8K can walk while watching.”
Two dogs although some depressed, but still full of hope, after all, spring has arrived.
Also shot cloud video processing solutions
In fact, to obtain and use a H.265 coding video is very convenient, directly use and shoot cloud H.265 video use scheme. The scheme integrates video uploading, video storage, video encoding (transcoding), video distribution adaptation, video decoding and other functions.
1. Video upload transcoding: Youpai cloud storage can meet the requirements of video upload acceleration, transcoding and storage. On the basis of cloud storage, users can synchronize h.264 encoded video to H.265 encoded video for storage.
2. Video asynchronous transcoding: For h.264 encoded videos stored in Wapaoyun, wapaoyun asynchronous transcoding service can be converted to H.265 video storage, while retaining h.264 video copy;
3.H.265 Distribution adaptation: The H.265 distribution adaptation function is provided at the LEVEL of Youpaiyun CDN, which can intelligently identify different clients and respond to different coded video resources when users access them.
