Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.
The embodiment of the application provides a data receiving method, which can be applied to a server, wherein the server can be an independent server or a server cluster formed by a plurality of servers, and can also be a cloud server for providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDNs, big data, artificial intelligent sampling point equipment and the like. Referring to fig. 1, the method includes:
s11: receiving first data with a preset byte length;

S16: the first data is released.
In some embodiments, in steps S3 and S5, after the first data is released, the first data of the first preset byte is continuously received.
Taking the RTSP protocol interleaved mode as an example, a field called Transport is included in the SETUP signaling and a field called interleaved is included in this field, which field must be in a state of value in this mode. Examples are as follows:
transport RTP/AVP/TCP; interleaved=0-1 or
Transport:RTP/AVP/TCP；interleaved＝2-3
Wherein the value of interleaved is non-standard and is formulated by the protocol manufacturer. The media stream is in the form of a 1 byte $+1 byte channel identifier +2 bytes rtp/rtcp data length + media data + upper layer header information during transmission.
Firstly, receiving media data of 4 bytes, when the content of the first byte (first sub data) is '$' (first identification information), continuously judging whether the next byte (second sub data) is an interrupted set value (second identification information), if not, skipping the acquired content, and re-matching the character '$'; if the packet can be paired with the value set in interleaved, the content of the data packet which is rtp or rtcp can be judged by using the value set in interleaved; when the next 2 bytes of data (third sub data) are acquired, the two bytes of data are the real content length (fourth sub data) of the media stream data, the data of the byte with the specified length can be acquired according to the content length, the data content acquired now is the actual media stream data, and the subsequent upper header information is not needed, so that the receiving processing logic of the part can be skipped directly in general, and the receiving processing of the media stream data can be continued.
In the implementation process, first data is received first, if the first identification information is included in the first data, further identification can be performed, and if the first identification information is not included in the first data, the first data can be directly released without receiving the first data. When the first data comprises the first identification information, the first data is further identified, if the second identification information is included, fourth sub-data is extracted from the first data, the fourth sub-data obtains media stream data, and otherwise, the first data is lost. The whole process of obtaining the media stream data does not need to store the first data for a long time and locally, multiple judgment is carried out, if the first data is not accordant with the requirement of directly discarding the first data, the storage pressure is reduced, the media stream data is obtained through the finally analyzed fourth sub-data, the steps of obtaining redundant data and analyzing the redundant data to obtain the media stream data are avoided, and the receiving speed of the media stream data is improved.
In some embodiments, prior to receiving the first data of the preset byte length, the method comprises:
judging whether the signaling comprises third identification information in the signaling interaction stage;
if so, a channel is opened to receive media data, the media data including first data and media stream data.
Taking the interleaved mode of the RTSP protocol as an example, in the signaling interaction stage, when the signaling is identified to include the interleaved field (the third identification information), it can be known that the current mode of obtaining the media stream is the media data transmitted through the signaling channel, and the signaling and the media data are transmitted in an interleaved manner, and after the transmission mode is identified, the preset media data can be received.
In the implementation process, a signaling interaction stage is needed in the process of communication between the receiving end and the server, and whether to prepare for receiving the media stream data is determined by judging whether third identification information is included in the interaction stage, so that the response speed and the receiving efficiency of the receiving end to the media stream data are improved.
In some embodiments, before determining whether the second asset data of the first data includes the second identification information, comprising:
and taking a preset field value of preset signaling as second identification information in the signaling interaction stage.
Taking the RTSP protocol interleaved mode as an example, a field called Transport is included in the SETUP signaling and a field called interleaved is included in this field, which field must be in a state of value in this mode. Examples are as follows:
transport RTP/AVP/TCP; interleaved=0-1 or
Transport:RTP/AVP/TCP；interleaved＝2-3
The 2 values of the interleaved field are (second identification information), the first value being used for the rtp packet for identifying that the content of the packet is rtp data; the second value is used for the rtcp packet to identify that the content of the packet is rtcp data.
It is appreciated that in some embodiments, the second identification information is also used to identify the data type of the media stream data.
In the implementation process, the signaling interaction node uses the preset field value of the preset signaling as the second identification information, so that fourth sub-data meeting the requirements can be extracted from the plurality of first data, and corresponding media stream data can be obtained through the fourth sub-data.
In some embodiments, obtaining fourth sub-data at the third sub-data of the first data, obtaining media stream data from the fourth sub-data, includes:
taking the fourth sub data as the data length;
receiving second data according to the data length;
and acquiring media stream data according to the second data.
Illustratively, taking the interleaved mode of the RTSP protocol as an example, first receiving media data of 4 bytes, when the content of the first byte (first sub data) is '$' (first identification information), continuing to determine whether the next byte (second sub data) is the value (second identification information) set by interleaved, if not, skipping the content acquired this time, and re-matching the character '$'; if the packet can be paired with the value set in interleaved, the content of the data packet which is rtp or rtcp can be judged by using the value set in interleaved; when the next 2 bytes of data (third sub data) are acquired, the two bytes of data are the real content length (fourth sub data) of the media stream data, the data of the byte with the specified length can be acquired according to the content length, the data content acquired now is the actual media stream data, and the subsequent upper header information is not needed, so that the receiving processing logic of the part can be skipped directly in general, and the receiving processing of the media stream data can be continued.
In the implementation process, the fourth sub-data is used as the data length; the fifth sub data can be directly obtained by receiving the second data according to the data length, so that the data analysis time is saved, and the real-time receiving of the media stream data is realized.
In some embodiments, the data in the preset range in the second data is used as media stream data.
In the implementation process, the data in the preset range in the second data is used as the media stream data, so that the data analysis time can be saved, and the real-time receiving of the media stream data is realized.
Further, the first data is composed of second sub data, third sub data and fourth sub data according to a preset sequence.
In the implementation process, based on the preset sequence, the receiving end can rapidly analyze the second sub-data, the third sub-data and the fourth sub-data.
