Functions

av_encryption_info_add_side_data ubyte* 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().
av_encryption_info_alloc AVEncryptionInfo* av_encryption_info_alloc(uint subsample_count, uint key_id_size, uint 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.
av_encryption_info_clone AVEncryptionInfo* av_encryption_info_clone(const(AVEncryptionInfo)* info): Allocates an AVEncryptionInfo structure with a copy of the given data. @return The new AVEncryptionInfo structure, or NULL on error.
av_encryption_info_free 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.
av_encryption_info_get_side_data AVEncryptionInfo* av_encryption_info_get_side_data(const(ubyte)* 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.
av_encryption_init_info_add_side_data ubyte* av_encryption_init_info_add_side_data(const(AVEncryptionInitInfo)* info, size_t* side_data_size): Allocates and initializes side data that holds a copy of the given encryption init info. The resulting pointer should be either freed using av_free or given to av_packet_add_side_data().
av_encryption_init_info_alloc AVEncryptionInitInfo* av_encryption_init_info_alloc(uint system_id_size, uint num_key_ids, uint key_id_size, uint data_size): Allocates an AVEncryptionInitInfo structure and sub-pointers to hold the given sizes. This will allocate pointers and set all the fields.
av_encryption_init_info_free void av_encryption_init_info_free(AVEncryptionInitInfo* info): Frees the given encryption init info object. This MUST NOT be used to free the side-data data pointer, that should use normal side-data methods.
av_encryption_init_info_get_side_data AVEncryptionInitInfo* av_encryption_init_info_get_side_data(const(ubyte)* side_data, size_t side_data_size): Creates a copy of the AVEncryptionInitInfo that is contained in the given side data. The resulting object should be passed to av_encryption_init_info_free() when done.

Structs

AVEncryptionInfo struct AVEncryptionInfo: This describes encryption info for a packet. This contains frame-specific info for how to decrypt the packet before passing it to the decoder.
AVEncryptionInitInfo struct AVEncryptionInitInfo: This describes info used to initialize an encryption key system.
AVSubsampleEncryptionInfo struct AVSubsampleEncryptionInfo: Undocumented in source but is binding to C. You might be able to learn more by searching the web for its name.
