Live broadcasting: The existing Isma method. The process is as follows:
Video collection-> video encoding-> RTP packaging-> UDP multicast;
Audio collection-> Audio Encoding-> RTP packaging-> UDP multicast;
The above is the workflow of mp4live.
Live Video: mpeg ts stream mode. The process is as follows:
Video collection --> video encoding -->
Audio collection> Audio Encoding> TS packaging> RTP packaging> UDP multicast
The above is the workflow of TS stream.

Wowza is one of the most popular streaming media servers today, because of the need to set up a corresponding server, but do not want to use camera and other real live, so try to convert media files into live stream and then provide to Wowza live. Here to set the steps and the design of the VOD step out, hoping to let the needy people less detours.1. IntroductionWowzastreaming Engine 4 (aka the famous Wowzamedia Server?) is a high-performance, scalable streaming media server software that suppor
Objective:Whether it is the pursuit of retro analog tones or high-precision transparent sound quality, modern computer music production of the middle of the new EQ plug-in with its super-frequency shaping and personalized features for the tone of the touch-up and remodeling provides unlimited possibilities.Although EQ is not the most complex of audio engineering tools, the use of errors does have a big impact on sound. So, follow the 10 tips below to learn how to use modern equalization techniqu

First transferred into the "mute" after the accompaniment of the fate (accompaniment). mp3 ", select" Effect "→" filter "→" Parameter Equalizer ". This "parameter Equalizer" for beginners is not very intuitive, here is not very understanding of the eq

Step 1: The option request is optional as long as the server c

The signal edge slope on the transmission line slows down, the code element becomes wider, the amplitude decreases, and the jitter increases, causing the eye pattern to close and the error rate to rise.Pre-emp

Config server saves the metadata through config database, and MONGOs caches the metadata. The partition-related collections in config database are:
Config.changelog record meta data changes;
Config.chunks records the information of each chunk, including the Shard of Chunk, and the Min and Max values of chunk;
Config.lockpings and Config.locks Store the distributed lock related information, when the

I believe many of you want to play h264 video streaming media like me. However, a newbie often does not know where to start. Using Baidu, Google, and other search materials is a treasure. After N weeks of thinking, I made some achievements. It took a lot of useless effort. I spent a week watching the English protocol, and later I learned that there was a Chinese version, in addition, the goal I have achieved is very simple, as long a
Hadoop EqualizerWhile Hadoop is running, its datanode blocks become increasingly unbalanced, and unbalanced clusters can cause some datanode to be relatively busy.The Hadoop equalizer is a daemon. It re-allocates blocks, moving blocks from busy datanode to relatively idle datanode. At the same time, adhere to the replica policy, the replicas scattered to different racks, to reduce the data corruption rate.Cluster equalization Criteria: the utilization

The installation of Fedora22 is good, but there are still some problems. When playing the rmvb video, the sound is not synchronized with the screen. I have encountered it before. Fortunately, VLC can perfectly solve this problem, you can install it. A few simple steps: 1. directly use the root user su-2. Download the installation package: rpmfusion-nonfree-release-22.noarch.rpmrpmfusion-free-release-22.noarch
The installation of Fedora 22 is good, but
capabilities of the server.7. SED shortest expected delay . In fact, SED is similar to WLC, except that the number of inactive connections is not considered. The algorithm is: (the number of active connections +1) *256÷ weight, the same calculated value of the small server priority is selected.8. NQ never queue . Improved SED algorithm. We think about the situation in order to "never queue", that is, the number of connections to the server is 0, then if there is a server connection number of 0,
÷ weight, the same computed value of a small server priority is selected.
8, NQ never line up. An improved SED algorithm. We think about what circumstances can "never queue", that is, the number of connections to the server is 0, then if there is a server connection number of 0, the equalizer directly forwarded the request to it, without having to go through the SED calculation.
9, LBLC based on the least local connection. The
priority is selected.
Benefits: You can allocate requests based on the capabilities of the server. Sed the shortest expected delay. In fact, SED is similar to WLC, except that the number of inactive connections is not considered. The algorithm is: (Active connection number +1) *256÷ weight, the same computed value of a small server priority is selected.
