Hi, For this problem I have found a trick on this post > [@Cannot stream "extremists.mp4" from content directory using Safari](http://community.wowza.com/t/-/36667): > > I have followed the VoD tutorial and can play the sample.mp4 but there is also a file “extremist.mp4” in the content directory(which came with the download but it does not work with this file I am test HLS and using safari I am using URL http://[wowza-address]:1935/vod/mp4:extremists.mp4/ What am I missing? Thanks by creating HTML page with video tag and I were able to view the video with Safari. But this is not what I want! How can I configure Wowza server for iOS&MAC user can watch the video directly with their browser or apps? My colleagues have developed an application on iOS that allows user to push live stream, and watch videos recorded. But when they use this app to watch the sample.mp4 video on my Wowza server, the app couldn’t play the video and returned error: **Chunk with zero-length** And on the server I saw this in the error log: WARN server comment 2013-07-16 12:03:15 - - - - - 150.463 - - - - - - - - MediaReaderFLV.open: Metadata appears to be bad: sample.mp4 WARN server comment 2013-07-16 12:03:59 - - - - - 195.049 - - - - - - - sample open: java.io.FileNotFoundException: /usr/local/WowzaMediaServer/content/sample.flv (No such file or directory) Why “sample.flv”? when the app required sample.mp4? --- _[View the full topic](https://community.wowza.com/t/cannot-play-sample-mp4-on-safari/40792)._
