AVCodecContext* avcodec_alloc_context | ( | void | ) |
Allocate an AVCodecContext and set its fields to default values.
The resulting struct can be deallocated by simply calling av_free().

AVCodecContext* avcodec_alloc_context3 | ( | AVCodec * | codec | ) |
int avcodec_copy_context | ( | AVCodecContext * | dest, | |

) |
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_open() before you can use this AVCodecContext to decode/encode video/audio data.
dest | target codec context, should be initialized with avcodec_alloc_context(), but otherwise uninitialized | |
