Original commit message from CVS: * ext/alsa/gstalsamixer.c: (gst_alsa_mixer_update), (gst_alsa_mixer_get_volume), (gst_alsa_mixer_set_volume), (gst_alsa_mixer_set_mute), (gst_alsa_mixer_set_record), (gst_alsa_mixer_set_option), (gst_alsa_mixer_get_option): Update mixer (to sync with other sessions) if we try to obtain a new value. This makes alsamixer work accross applications. * ext/alsa/gstalsasink.c: (gst_alsa_sink_get_time): Only call sync functions if we're running, else alsalib asserts. * ext/ogg/gstoggdemux.c: (gst_ogg_demux_src_query): Sometimes fails to compile. Possibly a gcc bug. * gst/playback/gstplaybin.c: (gen_video_element), (gen_audio_element): Add a reference to an application-provided object, because we lose this same reference if we add it to the bin. If we don't do this, we can only use this object once and thus crash if we go from ready to playing, back to ready and back to playing again. Also add an audioscale element because several cheap soundcards - like mine - don't support all samplerates. * sys/ximage/ximagesink.c: (gst_ximagesink_xcontext_get), (gst_ximagesink_xcontext_clear), (gst_ximagesink_change_state): Fix wrong order or PAR calls. Makes automatically obtained PAR from the X server atually being used. |

decoderbin:
A bin with a sinkpad that decodes the data into raw formats. It works by sending
the input data through a typefind element and then recursively autoplugs elements
from the registry until a raw format is obtained. It will then create a new ghostpad
on itself to signal the app of the new pad.
TODO
- reuse of decoderbin, cleanup in READY state
- debugging
- threading after demuxing?
- better factory selection, based on Demuxer/Decoder types and ranks.
- error handling
baseplaybin:
A bin with an uri property. It will find the right source element from the registry
and connect a decoderbin to it. When going to the PAUSED state, it will iterate the
decoderbin and listen for new pad signals from it. It will connect a queue to each
new pad and will iterate the decoderbin until one of the queues is filled. It is
assumed that by that time all the streams will be found so that when leaving the
PAUSED state, one can query the number of streams in the media file with the given
uri.
Before going to the PLAYING state, it is possible to connect a custom element to
each of the streams. To do that, you have to add the element to the bin and then
connect the pad(s) from the stream(s). You do not have to add the elements in
a thread, the bin will take care of then when it's needed. You are allowed to use
threads inside the elements, of course.
The bin tries to be smart and doesn't add a queue when there is only one possible
stream.
TODO
- reuse, cleanup in ready state
- debugging
- when the first pad is closed, it's possible that another dynamic element is
added somewhere so that we need a queue for the first pad as well.
- error handling
playbin:
Extends baseplaybin, sets up default audiosink and videosink for first audio/video
stream detected. implements seeking and querying on the configured sinks.
TODO
- reuse, refcounting, cleanup in READY state
- debugging
- error handling
