...s a special value ... iirc all the codecs have 0 on the header pages. However for stuff like CMML (and possibly Kate) it can make sense to have a timestamp of 0 for the first data packet, to signify that it it active from the very beginning of the data. That's likely why we made sure to put a nr_headers field in skeleton, so that it's simple to keep track of which of a streams packets are headers. At the time though we were only really dealing with vorbis, theora, and speex; the first two have a fixed nr of headers (3) and the last has 2+extra_headers, where extra_headers can be read from the...

Evolution of this patch series: https://www.redhat.com/archives/libguestfs/2020-July/thread.html#00073 Instead of auth-script, this implements header-script and cookie-script. It can be used for similar purposes but the implementation is somewhat saner. Rich.
