37 * buffer should attach to certain group, and buffer mode control the buffer usage flow.
56 * mpp buffer group support two work flow mode:
90 * NOTE: commit interface required group handle to record group information
94 * mpp buffer group has two buffer limit mode: normal and limit
100 * limit mode : restrict the buffer's size and count in the buffer group. if try to calloc
184 * mpp_buffer_import_with_tag(MppBufferGroup group, MppBufferInfo *info, MppBuffer *buffer)
186 * 1. group - specified the MppBuffer to be attached to.
187 * group can be NULL then this buffer will attached to default legecy group
194 * buffer can be NULL then the buffer is commit to group with unused status.
200 * Add a external buffer info to group. This buffer will be on unused status.
202 * to decoder's buffer group. Then decoder will recycle these buffer and return buffer reference
208 * buffer group. So the group is set to NULL. Then this buffer can be used for MppFrame/MppPacket.
210 * It does not need complicated group management. But in other hand mpp still need to know the
212 * of buffer to default misc buffer group for management.
