| int ff_imf_parse_cpl_from_xml_dom | ( | void * | log_ctx, |
| xmlDocPtr | doc, | ||
| FFIMFCPL ** | cpl | ||
| ) |
Parse an IMF CompositionPlaylist element into the FFIMFCPL data structure.
| [in] | log_ctx | Logging context (points to an instance of AVClass). May be NULL. |
| [in] | doc | An XML document from which the CPL is read. |
| [out] | cpl | Pointer to a memory area (allocated by the client), where the function writes a pointer to the newly constructed FFIMFCPL structure (or NULL if the CPL could not be parsed). The client is responsible for freeing the FFIMFCPL structure using ff_imf_cpl_free(). |
