Wowza Default RTMP player very poor quality why?

burak_guder · December 29, 2014, 4:06am

hi wowza team

I am using wowza rtmp player but very poor quality.

How can I improve the quality of the player in?

sal_jefferson · December 29, 2014, 6:28am

Hello there.

Can you please provide a little more detail about the stream in question:

What is the bandwidth in kbps / mbps
What is the stream resolution set to?
What is the codec of the stream? (H.264/AAC-44.1kHz/FPS/KeyFrame Intervals/etc…)
Is the stream live or VOD?
If live what is the source?

We look forward to hearing back from you and getting this issue resolved.

Kind regards,

Salvadore

Are you able to reproduce the problems you experience with the default player that ships with Wowza? [install-dir]/examples/VideoOnDemandStreaming/FlashRTMPPlayer/player.html

If you have the same issues with the default player, please send your findings to support@wowza.com to open a ticket.

You can use the code in the default player as a starting place/reference to develop a custom player. Assisting in the development of a custom player is beyond the scope of the support forum.

You will find many talented developers eager to assist you in the find a consultant forum

Kind regards,
