I am new with Wowza so can u pls help me to explain this issue?. I try copy new Mp4 file into Content folder and play it. However there is only audio played while videos are not displayed. The sample file is still running well. So is there any problem with my config or files??? Thank you very much! ---

If sample.mp4 plays and your file doesn’t, it’s an encoding issue. Open the stream in VLC and see look at Tools \> Codec Info. What info is displayed for the video? Richard ---

The audio is okay, but the video is not supported (mpeg4 part 2). You can use the Wowza Transcoder to transcode to h.264 (mpeg4 part 10). Try FFmpeg or Expression 4 Encoder [https://www.wowza.com/docs/how-to-encode-video-on-demand-content](https://www.wowza.com/docs/how-to-encode-video-on-demand-content) Richard ---

Hi, Are you following our [vod encoding guide](https://www.wowza.com/docs/how-to-encode-video-on-demand-content)? Don’t follow the Silverlight path in Expression 4, it can work, but the fragemented mp4 files that produces are not the best choice (but do work) Open the resulting file in VLC and look at Tools \> Codec Info, or use FFprobe (comes with FFmpeg) to look at the audio and video track. Make sure you are using mp4: prefix (mp4:streamName) for playback in Flash rtmp clients. Richard ---
