Hi all When I play rtmp://localhost/vod/mp4:mytest.mp4 with mplayer, both in ubuntu 12.04 and CentOS 6.3, mplayer will be stalled, and ffplay works fine. But when I use Red5, both mplayer and ffplayer work fine, do you think it’s a bug in mplayer or in Wowza? BTW, mplayer could play rtmp://localhost/vod/mp4:sample.mp4 and rtsp://localhost:1935/vod/mp4:mytest.mp4. Best, An Yang ---

Hi I think its more likely an issue with the content itself. You can bring up the codec information for the content by typing: ffmpeg -i mytest.mp4 Jason ---

Hi Looking at the specs found here, [https://www.wowza.com/media-server#specifications](https://www.wowza.com/media-server#specifications) Wowza cant play ac3 audio. I can only assume that’s why the the player crashes when using Wowza to play mytest.mp4. Jason ---

Hi Does Wowza give a message of any kind in the logs? Jason ---

HI JasonH, Please note that mplayer could play rtsp://localhost:1935/vod/mp4:mytest.mp4 without any sound.
