Embodiment approach

[0097] An implementation manner of monitoring whether the RPC communication connection between the main control process and the original decoding process is disconnected is as follows:

[0098] Detect whether the named pipe used to support the RPC communication connection between the master control process and the original decoding process is disconnected inside the RPC communication connection between the master control process and the original decoding process; if disconnected, the state of the target callback function Parameter is set to 0; Judge whether the status parameter of the target callback function is zero at present by the main control process being in the target callback function; If it is zero, determine that the RPC communication connection between the main control process and the original decoding process has been disconnected.

[0099]The bottom layer of the RPC communication connection between the main control process and the original decoding process depends ...

Abstract

The invention discloses a decoding method and device for video resources. The method comprises the steps that when a main control process which is in communication with an RPC and an original decoding process decode and play a same target video resource, whether or not a RPC communication connection between the main control process and the original decoding process is broken is monitored; if yes, a new decoding process is created, and a new RPC communication connection between the new decoding process and the main control process is built; through cooperation of the new decoding process and the main control process, decoding of the target video resource continues, and then the target video resource is played. According to the decoding method and device for the video resources, the technical problem is solved that the decoding process finishes accidently or breaks down so that video playing of a player main program can be stopped.

Description

technical field [0001] The present invention relates to the field of video decoding, in particular to a video resource decoding method and device. Background technique [0002] In the prior art, audio and video are decoded in one process, and then the decoded audio and video are played. This solution is relatively simple and fast. [0003] But if you want to implement multiple player openings (multiple player opening is the ability to simultaneously open multiple video resources in one player, such as: video files or network video streams). As the number of additional videos increases, the system resources required by the process, such as CPU usage and memory consumption, will also increase. When the performance bottleneck of the process is reached, the playback effect will become worse and worse, the picture will become more and more stuck, and it will even cause the player to crash. In order to prevent this situation, an independent process decodes the video stream to a...
