Subject: [PATCH 0/6] Add audio support in v4l2 framework
Date: Thu, 29 Jun 2023 09:37:47 +0800 [thread overview]
Message-ID: <1688002673-28493-1-git-send-email-shengjiu.wang@nxp.com> (raw)
Audio signal processing has the requirement for memory to
memory similar as Video.
This patch is to add this support in v4l2 framework, defined
new buffer type V4L2_BUF_TYPE_AUDIO_CAPTURE and
V4L2_BUF_TYPE_AUDIO_OUTPUT, defined new format v4l2_audio_format
for audio case usage.
The created audio device is named "/dev/audioX".
And add memory to memory support for two kinds of i.MX ASRC
module
Shengjiu Wang (6):
media: v4l2: Add audio capture and output support
ASoC: fsl_asrc: define functions for memory to memory usage
ASoC: fsl_easrc: define functions for memory to memory usage
ASoC: fsl_asrc: Add memory to memory driver
ASoC: fsl_asrc: enable memory to memory function
ASoC: fsl_easrc: enable memory to memory function
