The Advanced Linux Sound Architecture (ALSA) - utilities
df6cfa77e3
Add support for processing pcm_caps objects.
For ex:
Object.PCM.pcm."0" {
name "Port0"
direction "duplex"
Object.Base.fe_dai."Port 0" {}
Object.PCM.pcm_caps."playback" {
name "Port0 Playback"
}
Object.PCM.pcm_caps."capture" {
name "Port0 Capture"
}
}
Would convert into:
SectionPCMCapabilities {
'Port0 Playback' {
formats 'S32_LE,S24_LE,S16_LE'
rate_min 48000
rate_max 48000
channels_min 2
channels_max 2
periods_min 2
periods_max 16
period_size_min 192
period_size_max 16384
buffer_size_min 65536
buffer_size_max 65536
}
'Port0 Capture' {
formats 'S32_LE,S24_LE,S16_LE'
rate_min 48000
rate_max 48000
channels_min 2
channels_max 2
periods_min 2
periods_max 16
period_size_min 192
period_size_max 16384
buffer_size_min 65536
buffer_size_max 65536
}
}
and the SectionPCM updated as follows:
SectionPCM {
Port0 {
id 0
dai {
'Port 0' {
id 0
}
}
pcm {
playback {
capabilities 'Port0 Playback'
}
capture {
capabilities 'Port0 Capture'
}
}
}
}
