When converting between AAC and Opus formats (aac2opus or opus2aac), the `av_frame_get_buffer` API is frequently called. The goal is to optimize the code logic and reduce the frequent allocation and deallocation of memory. In the case of aac2opus, av_frame_get_buffer is still frequently called. In the case of opus2aac, the goal is to avoid calling av_frame_get_buffer and reduce memory allocations. Before calling the `av_audio_fifo_read` API, use `av_frame_make_writable` to check if the frame is writable. If it is not writable, create a new frame. --------- Co-authored-by: john <hondaxiao@tencent.com> |
