Functions

av_hash_alloc
int av_hash_alloc(AVHashContext** ctx, const(char)* name): Allocate a hash context for the algorithm specified by name.
av_hash_final void av_hash_final(AVHashContext* ctx, ubyte* dst): Finalize a hash context and compute the actual hash value.
av_hash_final_b64 void av_hash_final_b64(AVHashContext* ctx, ubyte* dst, int size): Finalize a hash context and store the Base64 representation of the actual hash value as a string.
av_hash_final_bin void av_hash_final_bin(AVHashContext* ctx, ubyte* dst, int size): Finalize a hash context and store the actual hash value in a buffer.
av_hash_final_hex void av_hash_final_hex(AVHashContext* ctx, ubyte* dst, int size): Finalize a hash context and store the hexadecimal representation of the actual hash value as a string.
av_hash_freep
void av_hash_freep(AVHashContext** ctx): Free hash context and set hash context pointer to NULL.
av_hash_get_name const(char)* av_hash_get_name(const(AVHashContext)* ctx): Get the name of the algorithm corresponding to the given hash context.
av_hash_get_size int av_hash_get_size(const(AVHashContext)* ctx): Get the size of the resulting hash value in bytes.
av_hash_init void av_hash_init(AVHashContext* ctx): Initialize or reset a hash context.
av_hash_names const(char)* av_hash_names(int i): Get the names of available hash algorithms.
av_hash_update void av_hash_update(AVHashContext* ctx, const(ubyte)* src, int len): Update a hash context with additional data.

Manifest constants

AV_HASH_MAX_SIZE enum AV_HASH_MAX_SIZE;: Maximum value that av_hash_get_size() will currently return.

Structs

AVHashContext struct AVHashContext: @example ffhash.c This example is a simple command line application that takes one or more arguments. It demonstrates a typical use of the hashing API with allocation, initialization, updating, and finalizing.
