To remove (hopefully) some confusion from (amongst other things) the
GStreamer side of things.
* HDV/AVCHD in this context means the camera with the 'official' HDV or AVCHD
specifications. People linked to those above. Both those formats use mpeg-ts as
the container format. If your camera does not record to mpeg-ts... it's not an
HDV- or AVCHD- compliant camera.
* The problems aren't that you can't playback the files, but that the support
isn't pristine.
* HDV files *playback* fine with latest GStreamer module releases.
* most AVCHD files *playback* fine with latest GStreamer module releases.
The problem here is 'perfect'/'fast' seeking support for those two
variants of mpeg-ts. The current gstreamer mpeg-ts demuxer (mpegtsdemux
in gst-plugins-bad) was never designed with random-access in mind (it
was developed for DVB/streaming support), and that's the root of the
issue with those files.
The HDV/AVCHD specifications extend the mpeg-ts usage in very subtle ways
making the poor seeking handling in mpegtsdemux even more visible (and in some
cases creating A/V sync issues :( ).
Those issues have been known for over a year... but mpegtsdemux is alas tricky
code to meddle with and past efforts have only resulted in poor man's seeking
capability.
An attempt was started by Zaheer Merali and myself to create a mpeg-ts
demuxer from scratch reusing the, much cleaner, mpeg-ts parse codebase
which takes into account all those issues and provide a base class for
all mpeg-ts variants/use-cases. Problem is... this is low on our
respective tasklists :(
P.S. And yes, poor seeking support = realy bad support of HDV/AVCHD
in PiTiVi and any other gst-based applications who need proper seeking
behaviour in mpeg-ts.
