Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with being embodied as
Example, and referring to the drawings, the present invention is described in more detail.
Embodiments provide a kind of live TV stream software transcoding task management method.Reference Fig. 1, for
The live TV stream software transcoding task management method flow chart of the embodiment of the present invention.
Described live TV stream software transcoding task management method, comprises the following steps:
The transcoding parameter information that step 101, reception user side are submitted to, and it is deposited into data base；Described
Transcoding parameter information includes: the source address of flow data and transcoding object format.
In this step, first receive user side and send the transcoding parameter information of coming, general, transcoding parameter
Information is sent to Relay Server by user side side in the way of transcoding request, then connecing by system side
Mouth API receives.Wherein, transcoding parameter information includes: the source address of live TV stream data and transcoding target
Form；Additionally, typically will also include other transcoding parameter, if desired for carrying out several roads transcoding.Receive
After transcoding parameter information, data base can be deposited into, can carry out in subsequent steps for above-mentioned data
Quickly data are extracted；It addition, also the data being stored in can be carried out adaptation processing so that by different use
After the data of the different-format that family end software is submitted to are stored in described data base, when output in the same format
Output.
Step 102, set up transcoding task according to described transcoding parameter information, and call transcoding machine and start institute
State transcoding task.
In this step, from data base, capture corresponding transcoding parameter information, then set up transcoding task.
Then, described transcoding parameter information is sent to outside dispatching device, and returns according to described dispatching device
The schedule information returned, calls transcoding machine and starts to perform described transcoding task.Wherein, dispatching device receives
After transcoding parameter information, can be according to the source address of the live TV stream data in transcoding parameter information, in institute
State and transcoding machine cluster is chosen the transcoding machine closest with the source address of described live TV stream data, should
The address of transcoding machine returns as described schedule information.Described schedule information generally comprises: selected transcoding
The address of machine, the data for being completed by transcoding carry out the address of the Relay Server of unloading.According to described
Schedule information, selected transcoding machine, from the address acquisition live TV stream data of live TV stream data, starts described turning
Code task proceeds by transcoding.
During additionally, dispatching device chooses transcoding machine in transcoding machine cluster, except considering different transcoding machines
With the distance of live TV stream Data Source, further account for the most whether transcoding machine is in idle condition, with
And the disposal ability etc. of different transcoding machines.
The process of step 103, the in real time described transcoding task of monitoring, generates task status information；By described
Task status information compares with threshold condition, it is determined that whether the task status of described transcoding task
Normally；When being judged to abnormal, stop described transcoding task, and again build based on described parameter information
Vertical new transcoding task.
After starting transcoding task, the process of transcoding task is monitored in real time.During monitoring,
Generating task status information in real time, described task status information generally comprises: transcoding frame per second, task are held
The duration of row, current processed total amount of data etc..Task status information described in generation, by its with
The threshold condition preset compares, it is determined that the task status of described transcoding task is the most normal.Go out
In various different error reasons, such as network connection interruption, connect unstable, transcoding machine report error code
Deng, the every concrete data in task status information there will be and cannot receive or fluctuate, its meeting
Deviate continuously or less than every corresponding threshold condition, now, it is determined that the task status of transcoding task
For abnormal state.When being judged to abnormal, stop the execution of current transcoding task, return step
102, live TV stream data based on this transcoding task and parameter information, re-establish new transcoding task.
Wherein, described transcoding machine report error code is that transcoding machine sends due to operation irregularity, typically exists
When the data that transcoding machine processes make a mistake, transcoding chance sends error code.Such as, transcoding task sets
It is set to video data is carried out transcoding, and the live TV stream data that transcoding machine receives only comprises voice data,
Now transcoding machine will send error code, and when receiving the error code that transcoding machine sends, also can judge
The task status of transcoding task is abnormal state.
As seen from the above-described embodiment, the live TV stream software transcoding task management method of the present invention, according to user
The transcoding parameter information that end is submitted to sets up transcoding task, then monitors transcoding task in real time, and
When task status occurs abnormal, terminate the execution of current transcoding task and re-establish new transcoding task
Perform, it is achieved that a kind of effectively, efficiently to live TV stream software transcoding task controlled, can be real-time
The management checked.
With reference to Fig. 2, for another live TV stream software transcoding task management method flow chart implemented of the present invention.
As another specific embodiment, described live TV stream software transcoding task management method, including following
Step:
The transcoding parameter information that step 201, reception user side are submitted to, and it is deposited into data base；Described
Transcoding parameter information includes: the source address of flow data and transcoding object format.
Step 202, set up transcoding task according to described transcoding parameter information, and call transcoding machine and start institute
State transcoding task.
The process of step 203, the in real time described transcoding task of monitoring, generates task status information.
In the present embodiment, described task status information is transcoding frame per second.Accordingly, frame per second threshold it is preset with
Value, this frame per second threshold value is the frame per second that network connects the transcoding under normal, transcoding machine normal operating conditions.
Step 204, when the transcoding frame per second of described transcoding task is less than described frame per second threshold value and when keeping default
Time long, it is determined that the task status of described transcoding task is abnormal, return step 202.
In this step, real-time compares transcoding frame per second with frame per second threshold value, when transcoding frame per second is the lowest
Under the state that frame per second threshold value, i.e. transcoding frame per second are less than frame per second threshold value and keep a period of time, it is determined that transcoding
The task status of task is abnormal.Then, stop the execution of current transcoding task, return step
202, parameter information based on this transcoding task, re-establish new transcoding task.
Step 205, described task status information is sent to outside supervising device, make described monitoring dress
Put and do not report to the police when preset duration gets described task status information.
In step 203, after generating task status information, also task status information can be sent out with every 10 seconds
Send mode once, send it to the supervising device of outside.Supervising device does not has in 5 minutes at continuous print
When receiving task status information, then can report to the police, prompting staff needs to safeguard.
