| AVEncryptionInfo* av_encryption_info_alloc | ( | uint32_t | subsample_count, |
| uint32_t | key_id_size, | ||
| uint32_t | iv_size | ||
| ) |
Allocates an AVEncryptionInfo structure and sub-pointers to hold the given number of subsamples.
This will allocate pointers for the key ID, IV, and subsample entries, set the size members, and zero-initialize the rest.
| subsample_count | The number of subsamples. |
| key_id_size | The number of bytes in the key ID, should be 16. |
| key_id_size | The number of bytes in the IV, should be 16. |

| AVEncryptionInfo* av_encryption_info_clone | ( | const AVEncryptionInfo * | info | ) |
Allocates an AVEncryptionInfo structure with a copy of the given data.
Definition at line 63 of file encryption_info.c.
| void av_encryption_info_free | ( | AVEncryptionInfo * | info | ) |
Frees the given encryption info object.
This MUST NOT be used to free the side-data data pointer, that should use normal side-data methods.

| AVEncryptionInfo* av_encryption_info_get_side_data | ( | const uint8_t * | side_data, |
| size_t | side_data_size | ||
| ) |
Creates a copy of the AVEncryptionInfo that is contained in the given side data.
The resulting object should be passed to av_encryption_info_free() when done.

| uint8_t* av_encryption_info_add_side_data | ( | const AVEncryptionInfo * | info, |
| size_t * | side_data_size | ||
| ) |
Allocates and initializes side data that holds a copy of the given encryption info.
The resulting pointer should be either freed using av_free or given to av_packet_add_side_data().
Definition at line 125 of file encryption_info.c.
| AVEncryptionInitInfo* av_encryption_init_info_alloc | ( | uint32_t | system_id_size, |

| uint32_t | key_id_size, | ||
| uint32_t | data_size | ||
| ) |
Allocates an AVEncryptionInitInfo structure and sub-pointers to hold the given sizes.
This will allocate pointers and set all the fields.
