Extract CC data from an AVFrame.
Extract CC bytes from the AVFrame, insert them into our queue, and remove the side data from the AVFrame. The side data is removed as it will be re-inserted at the appropriate rate later in the filter.

Just like ff_ccfifo_extract(), but takes the raw bytes instead of an AVFrame.

Provide the size in bytes of an output buffer to allocate.
Ask for how many bytes the output will contain, so the caller can allocate an appropriately sized buffer and pass it to ff_ccfifo_injectbytes()

Insert CC data from the FIFO into an AVFrame (as side data)
