Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
The invention provides a method for automatically detecting the access of media equipment in real time by a front-end web page, which comprises the following steps:
the method comprises the steps that a webpage regularly obtains equipment identifications of all media equipment which are currently accessed to intelligent equipment;
judging whether the number of all the currently acquired equipment identifications is changed compared with the number of all the prestored equipment identifications;
if the number of the equipment identifications is judged to be changed, sending an option prompt box containing all the currently acquired equipment identifications to the user, receiving the equipment identifications selected by the user from the option prompt box, and accessing the media equipment corresponding to the equipment identifications into the webpage.
And if the number is judged not to be changed, not popping up an option prompt box (not operating).
In particular, the invention relies on modern browsers that support the webrtc protocol suite, such as chrome, firefox, etc.
Specifically, the intelligent device of the present application may be a device such as a computer that can open a corresponding web page through the browser to perform an online video conference, and the media device may be inserted into the intelligent device to play a media message in the intelligent device.
Specifically, the application scenario is generally a web online video conference. When a video conference is carried out, firstly, a video conference number is created on a webpage, a user joins the conference, and a browser pops up to inquire whether media equipment such as a camera or a microphone device is allowed to be used or not, so that permission is confirmed.
In particular, the media device includes one or more of various types of devices, for example, the media device may be one or more of a camera, a microphone, and a speaker.
Specifically, a timer is set on the web page, and a native api interface (enumerateddevices) of webrtc is used in the timer to obtain the device identifier accessed to the intelligent device (user computer) at intervals, and generally speaking, the interface returns the following information:
audioinut (microphone device) (which may be plural, obtained from the kind field);
videoiput (camera device) (may be multiple, obtained from the kind field);
audio output (which may be plural, obtained from the kind field);
more specifically, the specific data content returned is as follows:
InputDeviceInfo, wherein fields comprise deviceId, groupId, kid and label;
MedaiDeviceInfo, wherein the fields include deviceId, groupId, kid and label.
Specifically, initially, the timer obtains device identifiers of all currently accessed media devices through the enumerartedeivces interface (each media device has a corresponding field), and then stores all the device identifiers in a web page localstorage (local storage);
specifically, the timer uses the webrtc native api interface (enumerartedevices) as a unit in milliseconds to acquire media information corresponding to the media device accessed into the intelligent device (user computer) at intervals, the timer is executed in a millisecond-level non-inductive state, when the media device is not changed, a page does not have any prompt, but the timer can acquire the insertion and extraction conditions of the media device in real time, and the enumerartedeves interface is executed by depending on a client browser, is unrelated to a server side, and can acquire the changed state of the media device in real time.
Specifically, when a new device identifier, which is different from a media device originally accessed to the web page and selected by the user from the option prompt box, is obtained, the resource occupied by the original media device is closed first, and then the media device corresponding to the newly selected device identifier is transferred to getUserMedia of the native api interface of the web page.
Specifically, if it is determined that the number of the device identifiers changes in the video conference process, sending an option prompt box to the user includes two embodiments:
the first embodiment: and if the number of the current equipment identifications is reduced and the media equipment corresponding to the reduced equipment identifications is in the using state, sending an option prompt box containing all the residual media equipment to the user for the user to select.
The present application further optimizes the first embodiment: if the media devices corresponding to the reduced device identifiers are judged to be in an unused state while the number of the device identifiers is reduced, the reduced media devices are represented as unnecessary or standby media devices, at the moment, the webpage does not send an option prompt box (does not operate) to the user, and the interference caused by frequent popping of the option prompt box to the user can be reduced. And if the corresponding media equipment is in a use state, popping up an option prompt box, and after the user selects a new equipment identifier, transmitting the media equipment corresponding to the new equipment identifier into getUserMedia of a native api interface of the webpage.
Second embodiment: if the number of the equipment identifications is increased, an option prompt box containing all the newly added and original media equipment identifications is sent to the user for the user to select, and the user can select the new equipment identification or the equipment identification of the media equipment in use.
Specifically, the option prompt box comprises a plurality of parallel equipment identifications when being displayed, the front end of each equipment identification is provided with a corresponding circular option box, a mark is marked in a selection box of the media equipment in use, the lowest end of the option prompt box is provided with a confirmation button, and when the corresponding equipment identification is selected, the confirmation button is clicked.
Specifically, if the user wants to play media by using the current media device, the user does not need to click the device identifier of other media devices, and directly clicks the "confirm" button, and the webpage does not operate at this time. If the user selects another new device identifier, the web page closes the resources occupied by the original media device first, and then transfers the media device corresponding to the newly selected device identifier to getUserMedia of the native api interface of the web page.
Since the media device includes one or more different types of devices, preferably, after acquiring all current device identifiers, the method further includes: classifying all the device identifiers, for example, uniformly summarizing the device identifiers of the cameras into a first type list, uniformly summarizing the microphone device identifiers into a second type list, uniformly summarizing the speaker device identifiers into a third type list, and after the classification is finished, uniformly storing all the type lists into a localstorage (local storage).
Preferably, before issuing the option prompt box, the method further includes: and judging the types of the reduced or newly added equipment identifications and displaying all the current equipment identifications with the same types as the reduced or newly added equipment identifications in an option prompt box for the user to select. More specifically, the implementation procedure of the present embodiment is as follows:
when judging that the equipment identification is increased, searching a corresponding type list in a localstorage (local storage) according to the type of the increased equipment identification, classifying the newly added equipment identification into the corresponding type list after the corresponding type list is searched, and mapping the updated type list information into an option prompt box to pop out for a user to select;
when judging that the equipment identification is reduced, searching a corresponding type list in a localstorage (local storage) according to the type of the reduced equipment identification, removing the reduced equipment identification of the media equipment from the corresponding type list after the corresponding type list is searched, and mapping the updated type list information to an option prompt box to pop up outwards;
the media equipment corresponding to the type prompt can be reduced, a large number of equipment identifications exist in the option prompt box at the same time, continuous screening is not needed in the user selection process, and the selection complexity is reduced.
Preferably, the present application may further automatically help the user select the corresponding media device when the user does not select the corresponding media device when the time is out, and the automatic selection includes the following two embodiments:
the first embodiment: detecting whether the equipment identification selected by the user is received within a preset time period after the judgment that the quantity of the equipment identifications is reduced and the option prompt box is sent out;
if the equipment identification selected by the user is received within a preset time period, accessing the media equipment corresponding to the equipment identification into a webpage;
if the device identification selected by the user is not received in a preset time period, automatically selecting the device identification which is the same as the reduced device identification in type and has the highest user use frequency, and accessing the media device corresponding to the device identification into the webpage;
specifically, the predetermined time is generally 5 to 10 seconds, for example, when it is determined that the first camera is reduced and the option prompt box pops up a camera which is frequently used by the user for more than 5 to 10 seconds and does not receive the device identifier selected by the user, if it is detected that the second camera is a camera which is frequently used by the user, the web page automatically selects the device identifier of the second camera and accesses the second camera to the web page.
Second embodiment: detecting whether a device identifier selected by a user is received within a preset time period after the increase of the number of the device identifiers is detected and an option prompt box is sent out;
if the equipment identification selected by the user is received within a preset time period, accessing the media equipment corresponding to the equipment identification selected by the user into a webpage;
if the equipment identification selected by the user is not received within the preset time period, automatically selecting the newly added equipment identification, and accessing the media equipment corresponding to the equipment identification into the webpage;
specifically, for example, when the user newly inserts a microphone, the device identifier of the microphone selected by the user is not received in the option prompt box pop-up for more than 5-10s, and the webpage directly selects the device identifier of the microphone and accesses the microphone into the webpage.
Specifically, the execution process for calculating the device identifier with the highest user usage frequency in the first embodiment is as follows:
when a certain media device is transmitted into the getUserMedia of the webrtc native api interface, the webpage judges that the media device is used, at the moment, the number of times of use of the media device is +1, an accumulated value is formed, the accumulated value is stored in a corresponding type list for storage, and when the media device of the same type needs to be judged to have higher use frequency, the accumulated value is searched for and compared.
Specifically, a manual selection button is further arranged on the webpage, so that a user can manually select the media equipment which is automatically selected when the user feels that the media equipment is not appropriate in the conference process.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. Further, it is intended that the appended claims cover all such variations and modifications as fall within the scope and boundaries of the appended claims or the equivalents of such scope and boundaries.
