The present invention provides an audio and video transcoding method and device. The method includes: starting a task management thread and a task adjustment thread; task management thread: judging whether there is a new audio and video transcoding task added, and if so, adding the task based on the current task Quantity and the current number of streaming transcoding tasks to determine whether the addition is successful. If successful, determine whether to use the CPU or GPU to start the task; task adjustment thread: determine whether there are tasks in the current task adjustment thread. Use the situation to determine the adjustment parameters; start the transcoding task, check whether the task is completed, if it is completed, set the status to recyclable; if it is not completed, check whether the task is a file transcoding task, if not, the task is executed normally, if so, the status of the task Before each frame is transcoded, the execution speed of the task is controlled according to the adjustment parameters. This solution can not only effectively guarantee the picture effect of streaming transcoding, but also make full use of device performance to complete the file transcoding task.
Description
technical field [0001] The present invention relates to the technical field of audio and video transcoding, and in particular, to a method and device for audio and video transcoding. Background technique [0002] In recent years, with the continuous deepening of the informatization construction of the people's courts, there are more and more demands for audio and video integration and sharing. At the same time, courts at all levels are also setting up execution command centers, which objectively requires audio and video signals between various systems to be able to interconnection. In these application systems, there are various audio and video sources, which may come from different applications, some from digital courts, some from video surveillance, and some from video conferencing; even the same application, It may also come from different manufacturers, which leads to different audio and video specifications and encoding formats. Due to these reasons, the audio and vide...
