Functions

av_bsf_alloc
int av_bsf_alloc(const(AVBitStreamFilter)* filter, AVBSFContext** ctx): Allocate a context for a given bitstream filter. The caller must fill in the context parameters as described in the documentation and then call av_bsf_init() before sending any data to the filter.
av_bsf_flush void av_bsf_flush(AVBSFContext* ctx): Reset the internal bitstream filter state. Should be called e.g. when seeking.
av_bsf_free
void av_bsf_free(AVBSFContext** ctx): Free a bitstream filter context and everything associated with it; write NULL into the supplied pointer.
av_bsf_get_by_name const(AVBitStreamFilter)* av_bsf_get_by_name(const(char)* name): @return a bitstream filter with the specified name or NULL if no such bitstream filter exists.
av_bsf_get_class const(AVClass)* av_bsf_get_class(): Get the AVClass for AVBSFContext. It can be used in combination with AV_OPT_SEARCH_FAKE_OBJ for examining options.
av_bsf_get_null_filter
int av_bsf_get_null_filter(AVBSFContext** bsf): Get null/pass-through bitstream filter.
av_bsf_init int av_bsf_init(AVBSFContext* ctx): Prepare the filter for use, after all the parameters and options have been set.
av_bsf_iterate
const(AVBitStreamFilter)* av_bsf_iterate(void** opaque): Iterate over all registered bitstream filters.
av_bsf_list_alloc AVBSFList* av_bsf_list_alloc(): Allocate empty list of bitstream filters. The list must be later freed by av_bsf_list_free() or finalized by av_bsf_list_finalize().
av_bsf_list_append int av_bsf_list_append(AVBSFList* lst, AVBSFContext* bsf): Append bitstream filter to the list of bitstream filters.
av_bsf_list_append2
int av_bsf_list_append2(AVBSFList* lst, const(char)* bsf_name, AVDictionary** options): Construct new bitstream filter context given it's name and options and append it to the list of bitstream filters.
av_bsf_list_finalize
int av_bsf_list_finalize(AVBSFList** lst, AVBSFContext** bsf): Finalize list of bitstream filters.
av_bsf_list_free
void av_bsf_list_free(AVBSFList** lst): Free list of bitstream filters.
av_bsf_list_parse_str
int av_bsf_list_parse_str(const(char)* str, AVBSFContext** bsf): Parse string describing list of bitstream filters and create single @ref AVBSFContext describing the whole chain of bitstream filters. Resulting @ref AVBSFContext can be treated as any other @ref AVBSFContext freshly allocated by av_bsf_alloc().
av_bsf_receive_packet int av_bsf_receive_packet(AVBSFContext* ctx, AVPacket* pkt): Retrieve a filtered packet.
av_bsf_send_packet int av_bsf_send_packet(AVBSFContext* ctx, AVPacket* pkt): Submit a packet for filtering.

Structs

AVBSFContext struct AVBSFContext: The bitstream filter state.
AVBSFInternal struct AVBSFInternal: @addtogroup lavc_core @{
AVBSFList struct AVBSFList: Structure for chain/list of bitstream filters. Empty list can be allocated by av_bsf_list_alloc().
AVBitStreamFilter struct AVBitStreamFilter: Undocumented in source but is binding to C. You might be able to learn more by searching the web for its name.
