Have you played live
One of the most popular professions in 2016 should be live broadcast. Whether it is a game anchor or any other female anchor, the low threshold for entry, coupled with the rise and popularity of various APP live broadcast software, can basically be broadcast by one mobile phone, so everyone can be an anchor. It is this low threshold that also leads to the low level of some live broadcast effects, which is directly different from the traditional live broadcast industry. However, this low threshold is also an advantage that the traditional live broadcast industry does not have. It does not require too many complex equipment and operations. One computer or smart phone can carry out simple live broadcast, which is easy to use. However, with the popularization of mobile Internet and the emergence of high-end mobile phones, people are no longer satisfied with the live broadcast in a fixed room. After all, it will be boring to play for a long time. If you want to get more live broadcast attention and go to some outdoor attractions or live broadcast becomes popular, it is necessary to upgrade the equipment to play, but the premise is still high usability and inexpensive, It can be used with mobile phones.

What can Hemiao coding stick do
Shanghai Heniao Electronic Technology Co., Ltd., as a provider of comprehensive live broadcast solutions, not only launched mobile phone APP Hemiao Live and cloud platform, but also launched its own live broadcast hardware products, namely the front-end coding collection device Hemiao coding stick. This coding stick is a collection and coding device for live broadcast through mobile phones, which can be directly connected to mobile phones (powered by mobile phones) and supports high-definition 1080p @The 60fps HDMI video input and the USB2.0 H.264 hardware encoder enable access to various high-definition signal sources such as cameras, SLR cameras, broadcast guide stations, computers, etc., and can be used for live broadcast on the Internet with the help of Hibiscus LIVE mobile phone APP. In simple terms, Hemiao coding stick is to connect various video input sources and publish the collected video content to the network after editing and sorting with APP.

There are two models of this Hemiao coding stick. One is ordinary, without external audio input jack, and without HDMI and audio switch keys; The other is the Pro version, which has an external audio input jack and an audio switch key, and supports mixed live broadcast of external audio input and HDMI video. In brief, the difference between the two models is whether there is an AUDIO interface in the picture below, so before purchasing, confirm your own use needs and select the corresponding model to purchase.

The reason why it is called a live broadcast in the pocket is that it is small in size and light in weight, and its front size is the same as that of a credit card, so it will not take up too much space or add extra weight.

For this Hemiao Live APP, a brief introduction will be given first, followed by a practical operation experience. Its functions are very powerful. It has a live broadcast/guide console page, which can support various functions such as real-time subtitles, exclusive LOGO customization, competition score page, news title board, etc. At the same time, it can live stream on third-party platforms such as Panda, Douyu, YY, without too many complicated settings or operations. Both professionals and ordinary players can operate quickly. However, at present, the APP version is only Android version, and the IOS version has not been released yet.

OTG wires need to be powered but not recharged by the original crop coding rod
Before understanding, let's talk about the wires of accessories, a standard HDMI wire and a micro HDMI cable also provides two OTG cables, one is micro USB interface and the other is Type-C interface. For micro HDMI wire and Type-C interface wire, which is really a little surprise, can meet the needs of Type-C mobile phone users, as well as the needs of devices such as SLR. If you can provide mini HDMI cable will undoubtedly be more practical and cost-effective. After all, mini HDMI interface will be added to some sports cameras, mobile phones, tablets and other devices.

Since it is an OTG line, it means that the Hemiao coding stick can be directly connected to the mobile phone for use, and the power supply is provided by the mobile phone. There is no need for independent power supply, but it will consume part of the power of the mobile phone. Most of the current Android smartphones support OTG, and no additional settings or opening operations are required. However, it is safe to confirm whether your phone supports OTG functions before purchasing. For the mobile phone with live broadcast, the higher the configuration is, the better. It is recommended that the mobile phone with more than 3GB of memory can be used for live broadcast while charging.

The original ASUS and SAMSUNG data lines cannot replace the original OTG lines, because the Hemiao coding stick cannot be recognized in the APP. In addition, the Hemiao coding stick can use an external power supply to supply power independently, and can also provide current to the mobile phone, but it can not meet the charging demand of the mobile phone. From the actual use, it just doesn't consume the power of the mobile phone.

In addition to OTG cable, there is another kind of cable that needs attention: mini HDMI cable. After the mini HDMI connected sports camera (Xiaoyi sports camera and VIDIT) is powered on, the Hemiao coding stick does not recognize it, which may be related to the sports camera.

The Hemiao coding rod has a design of heat dissipation hole, which is designed at the top center position, and has a large area. At the same time, the fuselage is made of metal, which is more conducive to heat dissipation to a certain extent. The surface of the fuselage is treated by sanding technology. I prefer this treatment method, which has a good anti-skid feel.

The Hemiao coding stick adopts the design of a common mobile hard disk box, which can be divided into three parts, namely, an integrated outer box and removable side covers at both ends. There are two screws at both ends for fixation, which is easier to disassemble.

Although it is easy to disassemble, and I really want to know which processing chip is used, this subversive product has done a good job in terms of confidentiality measures, and the main chips have been erased.

Looking back at the interface design at both ends, on one side is the USB2.0 interface connecting the mobile phone for data transmission and the micro USB power supply interface used to independently feed the Hemiao coding stick, while in the middle is the switch between HDMI audio and external audio, which can switch the audio source freely. This is the design only available in the Pro version.

On the other side is the core part, which is used to connect the HDMI input interface of front-end acquisition devices such as TV box, SLR, camera, etc., and this unique Audio interface is used to connect special devices such as mixer. As for the two green indicators, as long as the Hemiao coding stick is connected to the mobile phone or the power indicator corresponding to the power supply, the power indicator will light up, and the state status indicator will light up only after entering the live broadcast status.

How to play with Hemiao coding stick
First, prepare the connected devices, whether mobile phones, sports cameras, UAVs or SLRs, to ensure the normal connection and fixation of the devices.

Next, you need to download a corresponding APP, that is, Hemiao Live. After logging in with the mobile phone registration account, scan the barcode on the instruction manual to activate it. You cannot use the Hemiao coding stick without activating it.

After opening the APP and accessing the Hemiao coding stick, if there is a pop-up, we can learn from Figure 2 above that Hemiao live has two play methods, one is for WeChat sharing live broadcast, and after the activity is launched and broadcast, it is directly shared with WeChat friends or circle of friends; One is to directly connect the live broadcast to the third-party live broadcast platform, which is relatively simple in setting. Follow the operation prompts. One thing to note is that this added activity is effective within 24 hours after the activation of the coding stick, which means that the live broadcast can be suspended halfway and can continue at any time within 24 hours.

After the mobile phone and the Hemiao coding stick are normally connected, the connected status will be displayed on the corresponding Hemiao coding stick and USB camera in the personal center. Other parameters can be set by default or according to your own actual situation, such as the live broadcast output code rate, live broadcast resolution and audio code rate, However, you should make reasonable settings according to your actual network conditions, especially when using 4G networks.

Here is another part worth explaining. You can also directly reference existing video sources on live broadcast, and support the secondary broadcast function. Whether it is common protocols such as rtsp, rtmp, or http, as long as you have a legitimate and stable video source. In addition, you can also directly select existing videos for live broadcast, which also has great application scenarios in practice.

Powerful, simple and easy to use seedlings live
After the preliminary preparation, let's see how to play live broadcast with Hemiao live stick. As the most concerned question, what functions can be used by the Hemiao live stick and Hemiao live? How about the live video quality? How about the delay?

It is powerful because you can freely select multiple playback sources and control settings. You can modify sound input, picture switching, picture in picture, etc. At the same time, you can add various layers, such as time, picture logo, text, title, and even score. You can set them separately or use them together. All settings related parts only need to be manually selected or input, which is simple and easy to use. Hemiao live can normally recognize the Bluetooth microphone connected to, such as the actual use of Sabin ALAYA 3D Bluetooth microphone. Manual switching can also be performed in real time on video screen and line switching, just a few clicks.

All recorded videos will be saved in the video folder in the APP software, and the recorded video files can be found directly in the category.

For the quality of live broadcast, first come a picture of the SLR and mobile phone camera. This is the default high-definition image quality, so the resolution is actually 720P, and the actual recorded film is also 720P.

This is an encoding format for actually recording films. The picture ratio is standard 16:9, and the video frame rate is about 27 fps.

If you want better picture quality, you need to manually select full HD on the setting page, that is, 1920X1080 resolution, which is also the maximum resolution supported by the Hemiao coding stick.

What about the parameters of 1080 movie? Take a look at the decoding analysis below. The resolution is 1920X1080 and the frame rate is 29fps.

Take a look at the display screen and live broadcast screen of several video input sources. Figure 1 is the picture of the TV box, which is displayed in real time on the switch. As long as there is a video source, whether it is a PC, laptop or SLR, the mobile phone can be viewed as a display screen; Figure 2 is the effect picture after adding various words and pictures, which can edit the screen content in real time, whether it is deleted or added; Figure 3 and Figure 5 are the renderings of playback of existing recorded films; Figure 4 shows the pictures of mobile games recorded directly with the mobile phone camera. The sound and pictures are relatively smooth in viewing without obvious delay or intermittent. Figure 6 shows the picture in picture effect composed of SLR camera and mobile phone camera, which is more interesting to play. There are not many built-in effect sounds in the sound effect part, which is relatively limited. You can add the existing music in your phone as the background sound for synthesis.

How to use this WeChat live broadcast? Quite simply, there is a QR code identification option at the bottom of the list on the left side of the live broadcast page. Open it and scan the QR code directly. One of the two QR codes is an ordinary user viewing page. You can send a pop-up screen by "saying to the anchor", or you can enter the management page to manage some functions, such as giving a reward, saying something or voting. You can also delete a user's pop-up screen. Of course, the live page can also be forwarded by one click to social platforms such as friends or circle of friends.

Is it worth buying
For users who do not play live broadcast, it is unnecessary to purchase because your use scenarios are limited. But for anchors or amateur players who use mobile phones to play live broadcast all the year round, it is necessary to purchase, and it is also worth paying attention to by some professional live broadcast personnel. The powerful expansion ability of Hemiao coding stick is very attractive, and it can easily access video sources, such as cameras, sports cameras, TV boxes, laptops, PCs, etc. With the function of Hemiao live APP， Whether it is WiFi or 4G network, the mobile phone is used as a guide station, which can easily and quickly add its own exclusive LOGO, edit real-time subtitles, set the title and score version, and easily play live broadcast, so that your live broadcast is no longer dull and inflexible. At the same time, you can directly click multiple audio and multiple video sources to switch quickly, without too many complicated settings or professional operations, Easy to use. Grass seedling live APP supports pandas, fighting fish, tiger teeth YY、 Longzhu and other mainstream live broadcast platforms have built in WeChat video live broadcast and support the function setting of secondary live broadcast, which has greatly improved the usage scenarios of Hemiao coding stick and APP. It is not enough to say that the Hemiao coding stick is a subversion of the live broadcast equipment. After all, its powerful functions and high portability are what traditional professional live broadcast equipment does not have.

But one thing to pay attention to is that if you want to use the Hemiao coding stick to play live broadcast, you must keep up with the configuration of your mobile phone. It is necessary to choose a mobile phone with high configuration, large capacity battery, which can charge while broadcasting. After all, the current Hemiao coding stick can neither independently power nor charge your mobile phone, and it needs to consume the battery power of your mobile phone when there is no external power supply.
