Fig. 4 is a kind of flow chart of the payload acquisition methods of SEI message provided in an embodiment of the present invention.Referring to fig. 4, This method comprises:

Step 401: the first equipment obtains SEI message.

It should be noted that SEI message can be used for the operations such as aid in treatment decoding, display, can believe containing timing Breath or it is other decoding video can be enhanced but nonessential supplementary data, SEI message can be carried in video flowing and be transmitted, And SEI message is carried in video flowing and will not influence the decoding of video data.

In addition, SEI message can be used to transmit self-defining data in the first equipment, specifically, the first equipment can be by institute The self-defining data to be transmitted is added in the data field of SEI message as the payload of SEI message, SEI message Payload is located at the end of SEI message.

Step 402: the first equipment determines the byte number of the payload of the SEI message.

It should be noted that the byte number of the payload of the SEI message is the length of the data field of the SEI message Degree.

Step 403: the first equipment obtains corresponding first character string of byte number of the payload of the SEI message.

It should be noted that the byte number of the first character string can be a, a can be pre-set numerical value, as a can be with It is 2,3 etc., the embodiment of the present invention is not construed as limiting this.

Specifically, the byte number of the payload of the SEI message directly can be determined as the first character string by the first equipment； Alternatively, can corresponding relationship according to the byte number of the payload of the SEI message, between the byte number and character string of storage In, corresponding character string is obtained as the first character string.

For example, the byte number of the payload of the SEI message is 8, the byte number of the first character string is 2, then the first equipment The byte of payload number of the SEI message directly can be determined as the first character string, the i.e. word of the payload of the SEI message Corresponding first character string of joint number is 8.

In another example the byte number of the payload of the SEI message is 8, the byte number of the first character string is 2, then first sets It is standby can be corresponding between byte number as shown in table 1 below and character string according to the byte number of the payload of the SEI message In relationship, obtains corresponding character string 2 and be used as the first character string.

Table 1

Byte number	Character string (2 bytes)
		7	Character string 1
8	Character string 2
		9	Character string 3
……	……

It should be noted that the only corresponding relationship shown in the above table 1 between byte number and character string of the embodiment of the present invention For be illustrated, upper table 1 not to the embodiment of the present invention constitute limit.

Step 404: the first equipment adds the first character string after the SEI message, obtains first message.

It should be noted that the first equipment adds the first character string after the SEI message to obtain first message, be The first character string is added after the payload of the SEI message to obtain first message.It at this time include the SEI message in first message With the first character string, the first character string is located at after the payload of the SEI message and the payload phase with the SEI message It is adjacent.

Step 405: first message is sent to the second equipment by the first equipment.

In practical application, SEI message can carry self-defining data, can not also carry self-defining data, the second equipment It usually only needs to parse the SEI message for carrying self-defining data (obtaining the payload of SEI message), without parsing not Carry the SEI message of self-defining data.Thus, in the embodiment of the present invention, determine in SEI message for the ease of subsequent second equipment Whether self-defining data is carried, and the first equipment can add mark data in first message, or can be in first message After add mark data.The mark data can be configured in advance, and the mark data is used to indicate in SEI message and carries Self-defining data.

Wherein, if the first equipment is to add mark data in first message, the first equipment can first disappear first Preset mark data is added in the playloadType field for the SEI message that breath includes, then directly sends first message To the second equipment.If the first equipment is to add mark data after first message, the first equipment can be first in first message After add the second character string, obtain second message, second message be then sent to the second equipment.

It should be noted that the first equipment adds the second character string after first message to obtain second message, be The second character string is added after the first character string in first message to obtain second message.It at this time include the SEI in second message Message, the first character string and the second character string, the first character string are located at after the payload of the SEI message and disappear with the SEI The payload of breath is adjacent, and the second character string is located at after the first character string and adjacent with the first character string.

In addition, the second character string, which is used to indicate in SEI message, carries self-defining data, the second character string can be pre- advanced Row setting, and the byte number of the second character string can be b, b can be pre-set numerical value, such as b can be 7,8, this hair Bright embodiment is not construed as limiting this.For example, the MD5 of some character string (Message-Digest Algorithm 5, pluck by information- Want algorithm 5) value be " 34c7733857d09dbf ", then can be denoted as the long long type data of 8 bytes " 0x34c7733857d09dbf ", using the long long type data as the second character string.

It is worth noting that being all often to add to preset in the playloadType field of SEI message in the related technology Mark data, but since the use of playloadType field is without constraint, so different vendor is in the mark wherein defined Data may be inconsistent, big so as to cause subsequent parsing difficulty.And in embodiments of the present invention, the first equipment can be first The second character string is added after message as mark data, subsequent second equipment can be directly according to the second of the end of second message Character string determines whether to carry self-defining data in SEI message, can so bypass the playloadType word of SEI message The otherness of section, compatible different vendor is in all cases to the customized extension of SEI message.

It should be noted that when first message or second message are sent to the second equipment by the first equipment, it can be by first Message or second message consign to plug-flow SDK (Software Development Kit, Software Development Kit), by plug-flow First message or second message are sent to the second equipment by SDK.Also, it is set first message or second message are sent to second When standby, it can be and first message or second message are individually sent to the second equipment, be also possible to disappear first message or second Breath splicing is sent to the second equipment in video frame, and the embodiment of the present invention is not construed as limiting this.

Step 406: the second equipment receives the first message that the first equipment is sent.

It should be noted that whether can first judge the message after the second equipment receives the message that the first equipment is sent For the target message comprising SEI message, when the message is target message, continue to judge in SEI message that target message includes Whether carry self-defining data, so as to when determine carry self-defining data in the SEI message that target message includes when, from mesh First message is obtained in mark message.It, can be by drawing stream SDK to receive the message that the first equipment is sent in practical application, and judging should Whether message is target message, since SEI message generally falls into transparent transmission form in drawing stream SDK, so stream SDK is drawn to be somebody's turn to do determining When message is target message, target message can be dished out, continue to handle target message by the second equipment.

Wherein, judge the first equipment received send message whether be the target message comprising SEI message operation The relevant technologies can be referred to, the embodiment of the present invention is to this without elaborating.

Wherein, the second equipment judges self-defining data whether is carried in SEI message that target message includes, and when determining When carrying self-defining data in the SEI message that target message includes, the mode that first message is obtained from target message can be with First message is directly transmitted according to the first equipment or transmission includes the second message of first message to determine.When the first equipment It is data when directly transmitting first message, in the playloadType field of the available target message of the second equipment, when obtaining When the data got are preset mark data, determine that target message is first message；When the first equipment is that send include the When the second message of one message, the character string of the b byte at the available end positioned at target message of the second equipment works as acquisition When the character string arrived is the second character string, determine that target message is second message, and determine and remove the second character string in second message Except part be first message.

It should be noted that since second message is to add the second character string after first message to obtain, so working as mesh When the character string for marking the end of message is the second character string, the second equipment can determine that target message is second message, and can be with Determine that the part in second message in addition to the second character string is first message.

Step 407: the character string for a byte for being located at the end of first message is determined as the first character by the second equipment String.

Since first message is to add the first character string after SEI message to obtain, and the byte number of the first character string is A, so the character string for a byte for being located at the end of first message can be determined as the first character string by the first equipment.

Step 408: the second equipment obtains the corresponding byte of payload number of the first character string.

It should be noted that the corresponding byte of payload number of the first character string is the SEI message that first message includes The byte number of payload.

Specifically, the mode that the second equipment obtains the corresponding byte of payload number of the first character string can be set according to first The mode of corresponding first character string of byte number of the standby payload for obtaining SEI message is determined.When the first equipment is directly will When the byte number of the payload of the SEI message is determined as the first character string, the second equipment can be directly true by the first character string It is set to byte of payload number；When the first equipment is according to the byte number of the payload of the SEI message, from the byte number of storage In corresponding relationship between character string, when obtaining corresponding character string as the first character string, the second equipment can be according to One character string obtains corresponding byte number as payload from the corresponding relationship between the character string and byte number of storage Byte number.

For example, the first character string is 8, when the first equipment is directly to determine the byte number of the payload of the SEI message When for the first character string, the second equipment directly can be determined as byte of payload number for 8.

In another example the first character string is character string 2, when the first equipment is the byte according to the payload of the SEI message Number, from the corresponding relationship between the byte number and character string of storage, when obtaining corresponding character string as the first character string, the Two equipment can be according to the first character string, from the corresponding relationship between character string and byte number as listed in Table 1, acquisition pair The byte number answered is as byte of payload number, i.e., the byte of payload number is 8.

Step 409: the second equipment will be located at the first character string in first message before and the c adjacent with the first character string is a The character string of byte is determined as the payload of the SEI message, and c is the byte of payload number.

It should be noted that due to the payload that the byte of payload number is the SEI message that first message includes Byte number, so the second equipment can will be located at the first character string in first message before and the c adjacent with the first character string is a The character string of byte is determined as the payload of the SEI message.

It is worth noting that can directly be obtained according to first character string at the end of first message in the embodiment of the present invention Payload adjacent with the first character string in SEI message is taken, to realize the parsing to SEI message from back to front, is SEI message is parsed by reverse mode, so as to ignore the otherness of SEI message itself, around the effective of SEI message Other fields that may be present parse SEI message before load, and then can accurately obtain effective load of SEI message Lotus.

In order to make it easy to understand, being carried out below with reference to process of step (1)-(7) to the payload of above-mentioned acquisition SEI message Explanation.

(1) first equipment obtains SEI message, and corresponding first word of byte number for obtaining the payload of the SEI message Symbol string, the byte number of the first character string are a.

(2) first equipment successively add the first character string and the second character string after the SEI message, obtain second message, The byte number of second character string is b.

Second message is sent to the second equipment by (3) first equipment.

(4) second equipment receive the message that the first equipment is sent, and judge whether the message is the mesh for including SEI message Mark message.

(5) second equipment obtain the character for being located at the b byte at end of target message when the message is target message String, when the character string got be the second character string when, obtain target message in be located at the second character string before and with the second word The character string of a adjacent byte of symbol string is as the first character string.

(6) second equipment obtain the corresponding byte of payload number of the first character string.

(7) second equipment, which obtain, is located at the first character string before and the c word adjacent with the first character string in target message Payload of the character string of section as the SEI message, c are the byte of payload number.

In embodiments of the present invention, the first equipment obtains SEI message, and determines the byte of the payload of the SEI message Number, then obtains corresponding first character string of byte number of the payload of the SEI message, and the byte number of the first character string is a. Later, the first equipment adds the first character string after the SEI message, obtains first message, and first message is sent to second and is set It is standby.When second equipment receives the first message of the first equipment transmission, the character of a byte at the end of first message will be located at String is determined as the first character string, the corresponding byte of payload number of the first character string is then obtained, later, by position in first message Before the first character string and the character string of the c byte adjacent with the first character string is determined as the payload of SEI message, c For byte of payload number.In this way, the parsing to SEI message from back to front is realized, so as to around the effective of SEI message Other fields that may be present parse SEI message before load, and then can accurately obtain effective load of SEI message Lotus.
