Mediatool Tool Description

[English | 简体中文]

The Mediatool test program is used to test the Media Framework API, which can simulate real-world usage scenarios.

Configure the Mediatool

Configure the CPU to use the mediatool tool, e.g. AP.

CONFIG_MEDIA=y                        //For cpus that need to use Media, enable this option.
CONFIG_MEDIA_TOOL=y                   //Open the mediatool tool
CONFIG_MEDIA_SERVER_CPUNAME='audio'   //Media-capable cpu name

CPUs that provide media capabilities (running mediad), such as AUDIO.

CONFIG_MEDIA_SERVER=y                         //Media-capable cpu, enable this option
CONFIG_MEDIA_SERVER_CONFIG_PATH="/etc/media/" //Set the directory where media-related configuration files are placed, by default
CONFIG_MEDIA_SERVER_PROGNAME="mediad"         //media deamon program name, default
CONFIG_LIB_FFMPEG=y
CONFIG_LIB_FFMPEG_CONFIGURATION="--disable-sse --enable-avcodec
 --enable-avdevice --enable-avfilter --enable-avformat --enable-decoder='aac,aac_latm,flac,mp3float,pcm_s16le,libopus,libfluoride_sbc,libfluoride_sbc_packed' --enable-demuxer='aac,mp3,pcm_s16le,flac,mov,ogg,wav' --enable-encoder='aac,pcm_s16le,libopus,libfluoride_sbc' --enable-hardcoded-tables --enable-indev=nuttx --enable-ffmpeg --enable-ffprobe --enable-filter='adevsrc,adevsink,afade,amix,amovie_async,amoviesink_async,astats,astreamselect,aresample,volume' --enable-libopus --enable-muxer='opus,opusraw,pcm_s16le,wav' --enable-outdev=bluelet,nuttx --enable-parser='aac,flac' --enable-protocol='cache,file,http,https,rpmsg,tcp,unix' --enable-swresample --tmpdir='/log'"
CONFIG_LIB_PFW=y

Running Mediatool in the sim environment

  1. Run ap,audio virtual machine:

    sudo ./nuttx

  2. Mount the directory. /music for media files, first mount the host path on the current core (ap):

    ap>mount -t hostfs -o fs=/home/jhd/music /music

  3. Run the mediatool：

    ap>mediatool

Test Methods

  • Play audio files (URL mode):

    open Music
prepare 0 url music/1.mp3          //Playback in URL mode
start 0                            //Start playback
stop 0                             //stop playback
close 0                            //Close playback

  • Play audio files (Buffer mode):

    open Music
prepare 0 buffer /music/1.mp3      //Playback in Buffer mode
start 0
stop 0
close 0

  • Record audio files (URL mode):

    copen cap
prepare 0 url music/2.opus
start 0                            //Start recording
stop 0                             //Stop recording
close 0                            //Close Recording

  • Record Audio Files (Buffer Mode):

    copen cap
prepare 0 buffer /music/b3.opus format=opus:sample_rate=16000:ch_layout=mono
start 0
stop 0
close 0

  • Playback control:

    pause 0                            //pause playback
resume 0                           //Resume playback
seek 0 1000                        //Jump to 1000ms to play

  • Adjust the volume:

    volume 0 50                       //Set the volume to 50%

  • The Mediatool provides debug commands for logging:

    mediatool>dump
