In a scenario where pw-link is called without a session manager running,
the output port on a node will not exist. In such a case, we broke out
of the for loop with all_links_exist set to true and returning EEXIST.
The return of EEXIST gives a confusing error message. Fix this.
uint32_t i;
for (i = 0; i < SPA_N_ELEMENTS(some_array); i++)
.. stuff with some_array[i].foo ...
becomes:
SPA_FOR_EACH_ELEMENT_VAR(some_array, p)
.. stuff with p->foo ..
So that we can reuse optimized versions in unoptimized noise
functions.
Do allocation a little different so that we can align everything
from the start.
Loop though coefficients, when all are 0, clear the destination.
When only one coefficient is used, simply copy with volume.
Otherwise run the complete convolution.
Don't count the sum for unused matrix coefficients. When doing pairing,
we set the mask to ~0 and so we would otherwise count too much.
Apply normalization to the active matrix coefficients, not whatever the
loop variables end up being at the end of the loops.
This fixes several integer overflow problems in the POD parser, as well
as fixing a returns-twice warning from GCC and integer truncation
problems in SPA_FLAG_CLEAR and SPA_ROUND_DOWN_N. The integer overflows
can result in a tiny POD being treated as a huge one, causing
out-of-bounds reads.
When no maxlength is given, we use the MAXLENGTH value but we need to
round it DOWN (instead of up) because our buffer is only MAXLENGTH big.
Use CLAMP where we can.
When in capture mode, the maxlength exceeds MAXLENGTH, scale down the
fragsize instead.
Fixes noise in audacious when playing 6 channels sounds. float32 * 6
channels with the maximum buffer size would result in the ringbuffer
being overwritten.
A flush command is not supposed to stop playback but just clear the
current state. Normally, to avoid complications, an application will
Pause, Flush and optionally Start to do things smoothly without
interfering with the process loop, but things should not crash if that's
not the case.
Fixes#2726
Some clients may send headers with trailing whitespace, which can upset
subsequent parsing of the data into numbers. This patch removes such trailing
whitespace before further processing the header data.
Some Airplay devices announce themselves as using the ALAC (Apple Lossless Audio
Codec) format, while pipewire only supports the PCM codec. A look at the
Pulseaudio RAOP reveals that ALAC is supported there, but the encoding looks
exactly like what pipewire does for PCM. This patch adds support for ALAC, but
it uses the existing PCM infrastructure to send the audio data.
spa_pod_parser_can_collect and spa_pod_parser_getv were inconsistent
with each other. When parsing crafted POD, this could cause a type
confusion or stack overflow.
HFP 1.8 states in 4.35.1:
Due to the small inconsistency between the GSM standard [2]) and the current
Headset specification ([3]), the HF shall also accept the “=” symbol,
in place of “:”, as a valid separator for this unsolicited result code.
iOS seems to use "=", so accept that as well.
See #2463
Both HFP and HSP require an AT command from HF/HS to AG to
be terminated by CR, not LF. (HFP 1.8, 4.34.1; HSP 1.2, 4.8.1)
See #2463
