Function avcodec_close

pub unsafe extern "C" fn avcodec_close(
    avctx: *mut AVCodecContext,
) -> i32

Close a given AVCodecContext and free all the data associated with it (but not the AVCodecContext itself).

Calling this function on an AVCodecContext that hasn’t been opened will free the codec-specific data allocated in avcodec_alloc_context3() with a non-NULL codec. Subsequent calls will do nothing.

@deprecated Do not use this function. Use avcodec_free_context() to destroy a codec context (either open or closed). Opening and closing a codec context multiple times is not supported anymore – use multiple codec contexts instead.
