What are the two different ways of splitting data in AnnexB and avcC?

Annex B and avcC are two different ways of organizing data for the H.264/AVC video encoding standard.

Annex B is a common method of data segmentation that divides video frames into byte streams, adding start codes and length information before each segmented frame. This method is typically used for transmitting or storing H.264/AVC video.

AVC is a data segmentation method based on the MP4 file format, which divides video frames according to the format of MP4 files and adds necessary information in the file, such as video parameter sets and sequence parameter sets. This method is commonly used for creating and playing MP4 files.

In conclusion, Annex B and avcC both involve dividing H.264/AVC video frames, but they use different formats and methods for dividing data and adding information.
