AVS3 Already Supported : https://github.com/debugly/ijkplayer/releases/tag/k0.11.7-beta-240905094015
but Where can I find a test source like AV3A?

Here are two channels with audio vivid(av3a). Need to set user agent to "iPhone"

#EXTINF:-1 tvg-id="CCTV4K" tvg-name="CCTV4K" http-user-agent="iPhone" group-title="央视-菁彩声",CCTV4K
http://148.135.93.213:81/live.php?id=CCTV4K-av3a
#EXTINF:-1 tvg-id="CCTV16" tvg-name="CCTV16" http-user-agent="iPhone" group-title="央视-菁彩声",CCTV16-4K
http://148.135.93.213:81/live.php?id=CCTV16-4K-av3a

@trial I copied https://gitee.com/openharmony/third_party_ffmpeg source code, add av3a parser and demuxer on develop branch, but av3a Decoder is absent, because av3a decoder is not open source code. I can't find av3a decoder source code at present.

If you play av3a audio, you will get av3a not find warning:

[17:18:08 479] [IJKMEDIA] : Audio: av3a (av3a / 0x61337661), 48000 Hz, 10 channels (16 bit), 384 kb/s
[17:18:08 479] [IJKMEDIA] No codec could be found with id av3a

Please wait for av3a source to open!
