  Here is my buildconf which appears correct :

  


  $ ffmpeg -buildconf

  However the filter drawtext is not enabled :

• Converting HLS Stream to stream supported by old radio

  29 novembre 2024, par Alberto Faenza

  I have an old internet radio that does not support HLS streams.
Therefore I cannot listen to my favourite radio at this url :
https://streamcdnf31-4c4b867c89244861ac216426883d1ad0.msvdn.net/radiodeejay/radiodeejay/master_ma.m3u8

  


  I found a solution using a paid software https://minimradio.com/ which is based on minimserver and minimstreamer.

  


  This solution works if I install mininmserver and minimstreamer on a local computer and use the internet radio to point to the converter stream but I will have to pay if I want to use this.

  


  Checking the documentation of minimradio and ministreamer I can see the following :

  


  *Some internet radios can play the previous AAC ADTS streams but can't play these new HLS streams
...

  


  If the network stream URL points to an HLS .m3u8 master playlist or media playlist file, MinimStreamer reads this file and uses the HLS protocol to read the stream audio data and send it to the music player as a conventional HTTP stream. This makes the stream playable on music players that don't support the HLS protocol. The audio data in the stream must be encoded in AAC format.*
and not a single destination receiver I should use a streaming (broadcasting) server. What can I use to do that ?

  


  My question is the following :
Is there a way to replicate what minimstreamer is doing using ffmpeg ?
I have tried this :

  


  


  ffmpeg -re -i https://streamcdnf31-4c4b867c89244861ac216426883d1ad0.msvdn.net/radiodeejay/radiodeejay/master_ma.m3u8 -c copy -listen 1 -f mpegts http://192.168.1.9:10000

  


  


  which is playing corrctly in local vlc on the same computer. But when I stop VLC is got this error in ffmpeg :

  And if I try to connect from my internet radio I immediately got this error :

  What is the correct way to stream this one locally in order to be listened in my internet radio ?
Shall I use ffmpeg or can be done directly with ngnix ? Or shall I use both ?
