AVCodecContext* avcodec_alloc_context3 | ( | AVCodec * | codec | ) |
Allocate an AVCodecContext and set its fields to default values.
The resulting struct can be deallocated by calling avcodec_close() on it followed by av_free().
codec | if non-NULL, allocate private data and initialize defaults for the given codec. It is illegal to then call avcodec_open2() with a different codec. |

int avcodec_copy_context | ( | AVCodecContext * | dest, |
const AVCodecContext * | src | ||
) |
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.
dest | target codec context, should be initialized with avcodec_alloc_context3(), but otherwise uninitialized |
src | source codec context |

Get the AVClass for AVCodecContext.
It can be used in combination with AV_OPT_SEARCH_FAKE_OBJ for examining options.

int avcodec_get_context_defaults3 | ( | AVCodecContext * | s, |
AVCodec * | codec | ||
) |
Set the fields of the given AVCodecContext to default values corresponding to the given codec (defaults may be codec-dependent).
Do not call this function if a non-NULL codec has been passed to avcodec_alloc_context3() that allocated this AVCodecContext. If codec is non-NULL, it is illegal to call avcodec_open2() with a different codec on this AVCodecContext.
