This slightly amends the semantic of the property: prior to that
commit it represented the interval since the last accumulated buffer
after which the current line(s) had to be output even if incomplete.
After this commit, it represents the interval between "now" and the
first accumulated buffer, making it possible to report a useful
latency.
Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs/-/merge_requests/474>
In its standard mode, textwrap simply splits up text in chained
buffers into multiple lines / buffers, not keeping any state.
When accumulate-time is specified, multiple input buffers will be
wrapped together, outputting one-line buffers of text once a
sufficient width (specified by the columns property) is reached,
or the interval between two input buffers is greater than
accumulate-time.
This is useful to format the output of an element such as
awstranscribe, which outputs its transcription with one buffer
per word.
This new crate consists of two elements, jsongstenc and jsongstparse
Both these elements can deal with an ndjson based format, consisting
for now of two item types: "Buffer" and "Header"
eg:
{"Header":{"format":"foobar"}}
{"Buffer":{"pts":0,"duration":43,"data":{"foo":"bar"}}}
jsongstparse will interpret this by first sending caps
application/x-json, format=foobar, then a buffer containing
{"foo":"bar"}, timestamped as required.
Elements further downstream can then interpret the data further.
jsongstenc will simply perform the reverse operation.
cargo-c will produce a pkg-config file making it easier to statically
link plugins.
Also add 'static' features for plugins depending on < 1.14 as this is the
minimal required version to use static linking because of ABI changes in
core.
There is no way to dynamically ask Cargo to build static or dynamic lib
so we have to build both and pick the one we care when doing the meson
processing.
Fix#88
Only two uses of unsafely setting the pad functions is left:
- fallbacksrc for overriding the chain function of the proxy pad of a
ghost pad
- threadshare for overriding the pad functions after creationg, which
probably needs some fixing at some point
