The Timed Text Markup Language, a subtitle format used by Youtube and possibly a few others, is based on XML too. I have started working on a simple XML parser, but Michael quickly found a bug in my attempt to remove the recursiveness in libavfilter, and I consider it to be the highest priority. Therefore, I stopped shortly after implementing the framework API and input buffer handling. The API I have chosen is a push-pull one similar to the new BSF and codecs API: av_xml_parser_feed() then loop on av_xml_parser_get_next_event(). The events would be the start of an element, a key-value attribute, the end of an element, a closing element or a text node. Higher-level utilities are easy to build on top of this API: returning a single event for an element and all its attributes, reading from an AVIO context. Regards, -- Nicolas George
