Abstract
The invention discloses a method, system and device for acquiring a parameter set value of video code stream in transcoding business, aiming to solve the problem that videos can not be played due to video code stream decoding errors resulted from that a receiving end is incapable of acquiring the parameter set value of the video code stream in the existing transcoding business. The method is implemented as follows: determining the parameter set value corresponding to the video parameter information and coded format information when analyzing and acquiring the video parameter information and coded format information in a code stream request sent by a receiving end and judging that the corresponding information in SDP (stream download project) information of the video code stream to be sent of a source end is different from the video parameter information and the coded format information, and transmitting the determined parameter set value to the receiving end. In the embodiment of the invention, a code stream converter determines the corresponding parameter set information of the target code stream and provides the determined parameter set information for the receiving end based on the video parameter information and coded format information of the target code stream required by the receiving end, thus the receiving end can decode the received video code stream based on the parameter set value, thereby improving the success rate of decoding the video code stream.
Description
Technical field
The present invention relates to communication technique field, relate in particular to the method, system and device that obtain the parameter set values of video code flow in a kind of transcoding business.
Background technology
H.264 used the notion of parameter set in the video encoding standard, parameter set comprises: the sequence parameter collection (Sequence Parameter Set, SPS) and picture parameter set (Picture Parameter Set, PPS).Wherein sequence parameter collection and image parameter are concentrated the optional coding mode that comprises as image size, employing, and macro block is to information such as slice groups mappings.An activity command parameter set remains unchanged in an encoded video sequence, and a live image parameter set remains unchanged in a coded image.The value of these two parameter sets, it is the starting stage of setting up in session, as a property value of media description in the code stream descriptor (SDP), send to the receiving terminal of medium by the source end of medium, make the receiving terminal of medium resolve the follow-up code stream that receives according to SDP information is normal.
Generally speaking, the value of the parameter set that carries among the SDP, need the mode of the information of source end by reading the code stream of having encoded to obtain, this method is for coding in advance, and to carry out mutual situation more suitable when source end and receiving terminal have been set up session and carried out SDP afterwards.But when the transcoding that relates to code stream is professional, because source end and receiving terminal are different to the requirement of video parameters such as the code check of code stream, resolution, the code stream that the source end sends over, need conversion through the code stream conversion equipment, thereby obtain the required target code stream of receiving terminal, therefore in this process, can't get access to parameter set values.
For example, in the mobile video monitor business, though the mobile network has realized the third generation communication technology (3rd Generation, 3G)/the 4th generation communication technology (4th Generation, 4G) wait mobile network's technology of new generation, but the relative fixed network of its bandwidth is still lower, for in fixed network than the 512Kbps that is easier to realize, CLV Common Intermediate Format (Common Intermedia Format, CIF) video code flow, still unacceptable in the mobile network, can only be by lowering code stream, modes such as resolution carry out re-sending among the mobile network behind the transcoding to code stream.
Fig. 1 is for obtaining the implementation procedure of video code flow in the prior art transit code business, this process may further comprise the steps:
S101: receiving terminal sends code stream request, wherein the video parameter information of carrying its target code stream to be received in this code stream request to the code stream conversion equipment.
S102: after the code stream conversion equipment received this code stream request, Xiang Yuanduan asked input code flow.
S103: according to the video parameter information that the receiving terminal that receives sends, input code flow is changed, be met the target code stream of receiving terminal requirement, the target code stream after the conversion is sent to receiving terminal.
S104: receiving terminal is according to the decoder of the parameter information initialization self of the target code stream that receives.
Can see by said process, portable terminal is carrying out when mutual with the code stream conversion equipment, promptly before the video code flow that obtains the transmission of code stream conversion equipment, just should obtain the parameter set values of the video code flow that sends to self, so that to the decoder initialization of self, but in fact because the code stream conversion equipment has carried out transcoding to the video code flow that obtains, variation has taken place in the parameter of this code stream or the form of coding, promptly variation has taken place in the value of the parameter set of the code stream that provides of this source end, therefore this moment, the code stream conversion equipment can't obtain the parameter set values of the target code stream that sends to receiving terminal, thereby may cause receiving terminal that the object code stream that receives is decoded and error occur when playing, even cause the receiving terminal can't be the object code stream that the receives broadcast of decoding.
