David Schleef 51e6acad1f assrender: refactor blitting, avoid writing past end of buffer
Previous blitting code could potentially write past the
end of the buffer if the x or y position was odd, and for
the same underlying reason, didn't get the chroma registration
correct in the odd position case.

Sebastian Dröge 852be755dd assrender: Drop text buffers before the segment start and clip running time end to the segment stop 2010-02-27 11:43:49 +01:00
Sebastian Dröge 659776f1b1 assrender: Consume text buffers if they're to be displayed in the next 500ms
Instead of only consuming them if they're to be display now. Consuming
them then might make following buffers with the same timestamp to
be too late.

Eric Appleman febb13d26f assrender: Don't scan current working directory recursively for fonts
This can take a very long time and also libass will overwrite files
if there's an embedded font with the same filename as an existing file.

Fixes bug #575878 and #608706.

Sebastian Dröge d7e58ce0a9 assrender: For synchronizing the text, take the video running time of the next frame
This makes sure that libass already has all text buffers for the next frame
at the time when the next frame is processed. Without this text buffers
might be one frame late or not shown at all if they're only shown for a
single frame.

Sebastian Dröge a95d960527 assrender: The text and video duration should only compared as running time too
The end times of the text and video buffers could be different than
their start running time + duration because of different rates.

Sebastian Dröge 4a23c7e912 Random cleanup and smaller bugfixes
Use gst_element_klass_set_details_simple(), install properties
with static strings, create pads directly from the static pad
templates, directly put the segment into the instance struct,
use GST_MSECOND instead of numbers.

The PAR is a GstFraction and not a double, use gst_structure_get_fraction().

Simplify setcaps() functions.

Benjamin Schmitz 0bc20cb186 Add assrender plugin for rendering ASS/SSA subtitles
This element has the advantage over subparse's ASS/SSA
support that more features are supported, like fading,
by using libass. Fixes bug #481075.
