Hi mate,

I've faced a similar situation in a project of mine and here is what worked for me:

1 - Recompile your ffmpeg adding --enable-libx264 --enable-gpl parameters

2 - Execute ffmpeg -v verbose -i rtmp://<host>:<port>/<stream> -c:v libx264 -c:a aac -ac 1 -strict -2 -crf 18 -profile:v baseline -maxrate 400k -bufsize 1835k -pix_fmt yuv420p -flags -global_header -hls_time 10 -hls_list_size 6 -hls_wrap 10 -start_number 1 <pathToFolderYouWantTo>/<streamName>.m3u8

3 - Install a http server such as apache/jetty/nginx or any other.

4 - Make that folder you just mentioned on ffmpeg command (<pathToFolderYouWantTo>) to be accessible by an http url

5 - Create a simple html page like this:

<video controls width="480" height="270" src="<streamName>.m3u8"/

6 - Access it from any Apple device.

Although it worked for me, it had a huge delay due to conversion process and so on. In my case it was around about 1:40 secs.

Hope this works for you

Subject: [FFmpeg-user] Live RTMP stream to HLS

I have seen several topics but no final solution. I am able to download a
live stream using rtmpdump. I can save the file but don't wish to do so. I
want to "push" the stream into ffmpeg to convert it to HLS if possible. I
can't save the the file in mp4 format because it can not be viewed until the
download is complete.  This will be a live stream so there might not be an
end. I have seen some stuff on listen but have not been able to get the
syntax right. It took a while to get rtmpdump formatted correctly. Is ffmpeg
able to take the live stream and transcode, encode, convert to HLS?  If so
can I get some advice or a point in the right direction.
Thanks for the help.
