Description

Method for Automatically Recording and Locating Random Events of Blu-ray Players

technical field

The invention relates to the field of application programs, in particular to a log storage method of a Blu-ray player.

Background technique

In the daily use of Blu-ray players, there will be some random problems, especially in the early stages of software development. Since it appears randomly, there is a certain chance, and it is often "too late" to recall the previously tested steps and the content of the film source after the problem appears. For this reason, the existing patent CN201210505330.7 discloses a local storage method of a Blu-ray player log. When the method is recorded, all relevant kernel logs and application program logs will be recorded, and a large number of related logs will also appear during the specific recording. Logs with irrelevant operation steps not only increase the inconvenience of reading and reduce work efficiency, especially for those who do not understand program codes, they do not know how to understand and read. Furthermore, even if professionals know how to read the relevant kernel logs and application logs, they can only understand what the user has done, instead of actively telling how you did it, that is, it is impossible to link the specific time with the usage scenario at that time It is not easy to judge, so that when a fault occurs, it is time-consuming, laborious and difficult to find the relevant law or the probability of occurrence, and only rely on the limited memory points and logical thinking of the human brain to recall the operation.

Therefore, there is an urgent need for a method for simply and intuitively recording random events of a Blu-ray player.

Compared with the prior art, the present invention not only receives the kernel log and the application program log through the virtual terminal device, but also performs keyword screening on the kernel log and the application program log to obtain operation information and usage scenarios related to the operation (disc playing process, etc.), and correspond to the operation information related to the usage scenario to obtain the playback log, so that the user's operation behaviors in chronological order after power-on can be known through the playback log (for example, what source is played, what is the operation What button, the source path entered, the connected device, etc.), understand the corresponding operation behavior in the relevant use scene after power-on, not only makes the reading more concise and intuitive, saves and simplifies a lot of unnecessary and irrelevant logs information, and after a random event occurs, you can find out where the problem occurs at the first time, so as to selectively help users avoid some problems and quickly respond to user needs. At the same time, it also provides a valuable reference for the recurrence of problem points and the search for rules, so that software development can quickly locate the problem and improve the stability and reliability of the product system.

Preferably, before the step (2), there is also a step of setting the keyword: displaying the keyword group option for the user to select, and using the keyword in the keyword group selected by the user as the keyword in the step (2). The preset keywords. The present invention not only can directly select the preset keyword through the default keyword group option set in the factory, but also can artificially select the required keyword information, increasing the flexibility of random event recording.

Preferably, the keyword includes key information and/or source information and/or path information and/or connection device information.

Preferably, the step (3) specifically includes: (41) writing the playback log into a buffer; (42) saving the playback log in the buffer into a local storage device in time sequence as a local log file .

Preferably, the step (3) further includes converting the playing log into a flow chart and storing it, so that the playback record of random events of the Blu-ray player is in the form of a flow chart.
