title: Is concurrent stream limitation of Agora RTC SDK depend on video quality or only audio?
body: <p>In Agora FAQ I read one channel support 17 stream concurrently. Is this the limitation in case of only audio or low quality video streams are in the channel?</p>
  <p>As I see in Agora sdk 4.x streams are replaced by tracks. Does it change something on limitation?</p>
  <p>Thanks in advance,
  László</p>
