Hi,

We are having problems streaming FLV files on iOS devices via Wowza.

As per the specifications, I see the video and audio codecs part of this files are supported i.e. H.264 and AAC respectively.

Just the complete attriibutes of file for your reference

However, while streaming the file from Wowza pre-installed with AMI, I am getting the following errors

INFO server comment - ModuleStreamNameAlias.nameToAlias[play]: streamName:flv:amazons3/veromuse/veromuse\_kN4FUw\_output\_file\_flv.flv alias:{pattern: “\*” alias:"${Stream.Name}" wildcardMatches:{[0]: “flv:amazons3/veromuse/veromuse\_kN4FUw\_output\_file\_flv.flv”}} result:flv:amazons3/veromuse/veromuse\_kN4FUw\_output\_file\_flv.flv

INFO stream create amazons3/veromuse/veromuse\_kN4FUw\_output\_file\_flv.flv -

**Note: I see in wowza/conf/MediaReaders.xml file and I don’t see any FLVCupertino entry there. Also, I do not see the related class files in wowza/lib directory.**

**Just to let you know, this is not a VOD Streaming but VODS3. We are streaming contents uploaded on S3.**

Hi there. .flv is not supported on iOS devices. But since the video is encoded with H.264, and AAC you may be able to use an mp4: prefix

```auto
mp4:someFile.flv

```

Sometimes this will work.

For a simple fix, you can change the file container with this ffmpeg command:

```auto
ffmpeg -i in.flv -acodec copy -vcodec copy out.mp4

```
