(but not the AVCodecContext itself). avsubtitle_free ⚠ Free all allocated data in the given subtitle struct. avcodec_default_get_buffer2 ⚠ The default callback for AVCodecContext.get_buffer2(). It is made public so
it can be called by custom get_buffer2() implementations for decoders without

it can be called by custom get_encode_buffer() implementations for encoders without

simplicity, because the performance difference is expected to be negligible
and reusing a get_buffer written for video codecs would probably perform badly
due to a potentially very different allocation pattern. avcodec_send_packet ⚠ Supply raw packet data as input to a decoder. avcodec_receive_frame ⚠ Return decoded output data from a decoder or encoder (when the
