b046ba6e3a baseparse: Fix documentation, it's pre_push_frame and not pre_push_buffer 2011-10-20 16:59:01 +02:00

64493d9603 basebarse: Add detect vfunc to allow subclasses to do format detection before anything else
API: GstBaseParseClass::detect()

This is called with the first buffers until the subclass has finished detection
and only afterwards the original buffers are handled as before. The vfunc allows
detection of the stream format without breaking the upstream framing.

e3f2d7db71 baseparse: add getcaps function
Adds a getcaps function to the sink pad to make parsers propagate
downstream caps restrictions to upstream.

The pipeline "audiotestsrc num-buffers=100 ! faac ! aacparse !
"audio/mpeg, version=(int)4, stream-format=(string)adts" ! filesink"
wouldn't work because aacparse wouldn't propagate the adts restriction
upstream to faac.

This patch adds a default getcaps to the sink pad to simply proxy
downstream caps and also adds a 'get_sink_caps' function pointer
to GstBaseParseClass for subclasses that need more refined getcaps.

e8ccbf4ca9 baseparse: make GstBaseParseFrame handling more bindings-friendly
Change semantics of gst_base_parse_push_frame() and make it take
ownership of the whole frame, not just the frame contents. This
is more in line with how gst_pad_push() etc. work. Just transfering
the content, but not the container of something that's not really
known to be a container is hard to annotate properly and probably
won't work. We mark frames allocated on the stack now with a private
flag in gst_base_parse_frame_init(), so gst_base_parse_frame_free()
only frees the contents in that case but not the frame struct itself.

9d98c62f0e baseparse: rename _set_frame_props() to _set_frame_rate()
Seems like the best fit to what it does, and is shorter than
set_frame_properties() which might also have been confusing
because of GstBaseParseFrame.

5073948380 baseparse: replace format flags with gst_base_parse_set_{passthrough,syncable,has_timing_info}
This is more in line with e.g. GstBaseTransform's API, and makes for nicer
to read code. No getters for now since I don't see any use case for them,
the API is for subclasses, which usually know what format they're
dealing with already and hence know what they've set.

1874d63808 baseparse: make DRAIN and SYNC flags on baseparse, not the frame, and change to DRAINING and LOST_SYNC
The first because it seems a better fit conceptually, the second
to express booleanness. Also change the accessor macros for subclasses
to GST_BASE_PARSE_DRAINING and GST_BASE_PARSE_LOST_SYNC.

783dbb9a71 baseparse: add GST_BASE_PARSE_FLOW_QUEUED to queue buffers until caps are known
This is useful for parser like flacparse or h264parse which may need to process
some buffers before they can construct the final caps, in which case they may
want to delay pushing the initial buffers until the full and proper caps are
known.

4709a26473 baseparse: replace set_seek() with _set_average_bitrate() and FLAG_SYNCABLE
This makes more sense conceptually, since the bitrate may be used
to estimate a seek position if there's no seek table or just for
duration reporting/estimation if we can't seek. Also, even if the
format is not syncable, we could still seek by pushing data from the
start and using the segment to make downstream clip.

de16d5adb3 baseparse: rename GstBaseFormat to GstBaseFormatFlags and fix up associated API
Also change gst_base_parse_set_format(parse,flags,switch_on) to
gst_base_parse_set_format_flags(parse,flags) which is more in line
with the rest of our API and how the function is used.

f691be223e baseparse: don't expose GstAdapter in public header
None of the existing subclasses needs access to that, so there's
no reason to expose it for now.

e2bf3647f8 baseparse: move various segment-related members into the private instance struct
If none of the existing subclasses uses these, there's probably no
need to expose them at the moment. Keep the segment itself exposed
though.
