Abstract
The invention relates to an audio and video playing method for multimedia terminal external memorizer. A searching thread and a playing thread are started at the same time. The searching thread comprises the steps that audio and video file information in the external memorizer is read, and the read audio and video file information is stored in a searching list. The playing thread comprises the steps that a memory list stored when the external memorizer is logged off last time serves as a play list, and audio and video files, corresponding to the external memorizer, of the play list are played; after the audio and video file information in the external memorizer is read, the searching thread is logged off, and the searching list is updated into the play list; when the external memorizer is logged off, the current play list is stored as the memory list. The playing thread of audios and videos can be fast established, the audio and video files can be played within 3 seconds without reading the audio and video file information of the external memorizer completely, and the sense experience of users is enhanced.

At present, the audio-video document that external memorizer is play in multimedia terminal has all first read all fileinfos of external memorizer, according to all audio-video documents in external memorizer, sets up playlist, plays.A kind of vehicle-mounted end of patent of invention as open in China and vehicle-mounted end method for playing music (application number: 201110410416.7, the applying date: 2011-12-09), specific as follows:
Information in scanning read memory, described audio file information at least comprises song title and the path of this audio file;
After in storer, information reads, according to the incidence relation of audio file and the file described in it, form audio file and launch list, described audio file launches list and at least comprises Folder Name and described file subordinate tone frequency file title, and shows that this audio file launches list;
After described audio file expansion list forms, displaying audio file launches the audio file in list in order.
Above-mentioned player method need to scan the fileinfo that has read external memorizer, just can play after setting up playlist.When the quantity of documents of external memorizer storage is larger, the file of external memorizer storage is read in multimedia terminal scanning, and the time of setting up playlist is longer, therefore cause the time to be played such as user long, even may wait for and reaching more than 30 seconds, affect user's experience.
Summary of the invention
The object of the invention is to overcome shortcomings and deficiencies of the prior art, the audio frequency and video player method of a kind of multimedia terminal external memorizer is provided, make the broadcasting thread energy Rapid Establishment of audio frequency and video, the audio-video document information that does not need wait to read external memorizer completely just can be carried out the broadcasting of audio-video document.
Object of the present invention is achieved through the following technical solutions: the audio frequency and video player method of a kind of multimedia terminal external memorizer,
Start a search thread and simultaneously and play thread, described search thread is: read the audio-video document information in external memorizer, and the audio-video document information reading is stored in to search listing; Described broadcasting thread is: the memory list of preserving when the last time is exited external memorizer, as playlist, is play the audio-video document in its corresponding external memorizer;
Read after the audio-video document information in external memorizer, exited search thread, and search listing has been updated in playlist;
While exiting external memorizer, current playlist is stored as to memory list.
Preferably, described audio-video document information at least comprises file name and the path of audio-video document.
Preferably, before the step that the memory list of preserving is play as playlist, also comprise the step that memory list is screened when the last time is exited external memorizer, the step of described screening is specially: according to the audio-video document information of each audio-video document in memory list, whether directly search this audio-video document exists in external memorizer, delete in memory list the audio-video document information without corresponding audio-video document in external memorizer respective paths, and using the memory list after screening as playlist.
Preferably, when the memory list after screening be empty, broadcasting thread obtains the part audio-video document information set up in search listing as playlist, plays the audio-video document in its corresponding external memorizer.
Preferably, the audio-video document information that described memory list is served as reasons the last time audio-video document of current broadcasting is corresponding while exiting external memorizer and with its list that continuous several audio-video document information form up and down.
Preferably, described memory list storage is in Nand Flash.
Preferably, described external memorizer is SD card, USB flash disk or portable hard drive.
The present invention has the following advantages and beneficial effect compared to existing technology:
(1) the present invention starts external memorizer in multimedia terminal, the method that the audio-video document of its external memorizer is play adopts and starts a search thread and a broadcasting thread simultaneously, and using memory list that the last time preserves while the exiting external memorizer playlist when starting external memorizer, play the audio-video document in its corresponding external memorizer, make the broadcasting thread energy Rapid Establishment of audio frequency and video, do not need to wait for the audio-video document information that has read external memorizer completely, in 0 to 3 second, get final product playing audio-video document, improve user's sensory experience.
(2) after memory list is screened, if memory list is empty, play thread and obtain the part audio-video document information set up in search listing as playlist, play the audio-video document of its corresponding external memorizer, guarantee to make the broadcasting thread energy Rapid Establishment of audio frequency and video, do not need to wait for and read the audio-video document information of external memorizer completely, thereby guarantee to get final product playing audio-video document not needing to wait as long for.
(3) after the audio-video document information in having read external memorizer, exit search thread, and search listing is updated in playlist, in playing process, upgrade playlist and can current broadcasting not impacted, do not affect user and experience.
Accompanying drawing explanation
Fig. 1 is the process flow diagram of search thread in the present embodiment;
Fig. 2 plays the process flow diagram of thread in the present embodiment.
