#1722 invalid ATrpms stable packages include DVB-T patch which breaks mpeg2 transcoding Axel.Thimm@… lennier76@…

I've never submitted a ticket before so apologies in advance if something here is inappropriate. Somewhere between changeset 9486 and changeset 9656 something changed in the recording of DVB streams. Possibly this is related to the DVB Radio changes that I've seen discussed.

Here in Australia at least, the result seems to be additional streams being added to the resulting mpeg file, which appear to cause lossless transcoding to fail with a 'No more queue slots' error.

Two examples from the backend log follow. The first shows an additional stream #0.2 flagged as mpeg2 video at 90000 fps (!). As far as I'm aware from previous recordings only the first two streams are valid video and audio.

This second example is from a recording which actually does have additional streams, in this case two audio streams. The additional 'spurious' stream is #0.3 flagged as mp1 audio at 32kb/s. The same error results when lossless transcoding is attempted.

Reading the recent commits and changeset logs leads me to guess that perhaps this is an unintended side effect of the DVB radio patches, which occured within the changeset range where the problem manifested. It may well be peculiar to Australian DVB broadcasts, which I don't think currently have DVB radio, but may perhaps have something that confuses the DVB radio stream handling stuff in Myth.

If further information is required please let me know.



#13293 fixed Parse config.xml as an XML document Bill Meek <billmeek@…> Nick Morrott

The Perl bindings read the lines of config.xml as plain text strings, extracting the values of desired elements using matching (m##) and regex captures.

Ideally we would parse the document as XML and extract values directly from the data structure created by the XML parser.

Depending on the XML library(ies) used, this would also permit the configuration file to be validated against a suitable DTD/Schema.

This should either be modified to python (per the attached path) or worked out to automatically extract the compile time python version.
