A great god taught for all of you! I now do video decoding in graduation design and encounter a problem:
Against a frame in using ffmpeg hevc video image decoding, careful analysis found that the default code which thread_count=1, and the rest of the place also illustrates the default in hevc is of no use multithreading decoding, due to the requirements of the teacher, now it is better to change to multi-threaded decoding, speed up the processing speed, of course, the hevc standard support frame, Slice, CTU etc. Multiple layers of parallel, as long as not frame level parallel (because the teacher asked to speed up to a frame of the image decoding, has nothing to do with interframe) the present requirement, however, I don't know much about this, welcome each big god give advice or comments! May I describe is not very detailed, I am very hurry to solve this problem, this involves I graduate, if there is a great god can solve the grateful, can bring proper for economic gift, you great spirit can leave your contact way to discuss ~

Do you have a ffmpeg decoding HEVC code

CodePudding user response:

Ffmpeg WPP is the slice level parallel, it is necessary to enable coding end, such as choosing slice in parallel, can choose the number of parallel,
