-------------------------------------+-------------------------------------
This wav audio is calling avformat_find_stream_info, and ffmpeg
incorrectly identifies it as an mp1 file. When we use the api to transcode
it, we continue to call the avcodec_send_packet and avcodec_receive_frame
functions to obtain the audio content. Our program needs to transcode the
audio to pcm, so we call swr_convert, it had a coredump error.
After investigation, we found that swr_convert called the
invert_initial_buffer function, and when copying, the data pointer of src
was NULL.
