No idea why we need to run gst-indent twice on that file, but it
only seems to settle on a final format with minimal diff to the
one in git after two runs.
_create() is a pad function set by ourselves, therefore we're sure basesrc
is a GstFileSrc.
Speeds up _create() by 17% and the total call by 8% (instruction calls measurements
done with valgrind).
Fixes#610246
_get_range() is a pad function set by ourselves, therefore we're certain that
the parent is a GstBaseSrc.
Speeds up _get_range by 38%, and the total call by 30%. (valgrind instruction
calls measurements).
Fixes#610246
Initialize new_fd with DEFAULT_FD and fd with -1. Setting the property will set
new_fd and in _update_fd() we cehck fd against -1. Also add a coment about the
warning we get in the log from gst_poll_remove_fd(). We could get rid of the
warning if we want by tracking if fd has been added to fdset.
g_setprgname is implicitly called by g_option_context_new() with a check
to see if it's been set already, so set it before g_option_context_new()
Move version printing back until after the options have been parsed,
otherwise it won't work, since it evaluates a flag set by the
option parser.
Add check to make sure gst-plugin-scanner really gets installed where
we will look for it later, ie. paths and prefixes are set at configure
time and not specified via make.
Fixes#609941.
Adds a new function to GstByteWriter that writes
a constant value to a memory area (aka memset).
Useful for adding padding to buffers.
Also updates .def file and docs.
API: gst_byte_writer_fill()
Typefind might mess up pads modes (pull/push) if a
downstream element is plugged and its pads activated
in 'step 2' of typefind pads activation.
This happens because the following steps don't check
if we already emitted typefound due to upstream setting
caps on buffers being pulled in the typefind helpers.
Avoid that by checking if typefound is already emmited.
Fixes#608036
Updating the segment values must only be done while holding the
STREAM_LOCK and OBJECT_LOCK. This means, reading can be done as
long as one of them is held, not both, which removes some lock-unlock
blocks from performance critical code paths.
Also document, that gst_base_src_set_format() *must* be called in
states <= READY and add an assertion for this. Changing the format
later will completely mess up the segment information.
The problem lies in the fact that multiqueue will now operate somewhat
similarly to the flow aggregation logic of demuxers and therefore
will stopp whenever all downstream pads return NOT_LINKED and/or
UNEXPECTED and there's no more buffers to push.
The latest commits should not affect any regular use-case, but the bug
report will be kept open so the previous behaviour can be re-established
if needed.
Fixes#609486
When a downstream element returns GST_FLOW_UNEXPECTED we want to:
* let the dataqueue task running
* forward the flow return upstream.
This allows upstream elements to push EOS, and have that EOS event come
downstream.
Fixes#609274
