Function ffmpeg_sys_next::avcodec_copy_context

pub unsafe extern "C" fn avcodec_copy_context(
    dest: *mut AVCodecContext, 
    src: *const AVCodecContext
) -> c_int

Copy the settings of the source AVCodecContext into the destination AVCodecContext. The resulting destination codec context will be unopened, i.e. you are required to call avcodec_open2() before you can use this AVCodecContext to decode/encode video/audio data.

@param dest target codec context, should be initialized with avcodec_alloc_context3(NULL), but otherwise uninitialized @param src source codec context @return AVERROR() on error (e.g. memory allocation error), 0 on success

@deprecated The semantics of this function are ill-defined and it should not be used. If you need to transfer the stream parameters from one codec context to another, use an intermediate AVCodecParameters instance and the avcodec_parameters_from_context() / avcodec_parameters_to_context() functions.
