[FFmpeg-user] HLS setting NAME in EXT-X-MEDIA

Thanks Ted,

It's exactly what I'm doing. I'm rewriting the master playlist on the fly with NGINX.

The strange thing is that audio_1 and so on are arbitrary names set by ffmpeg by itself so I really don't understand if this is a expected behaviour or some flaw in the muxer design or a bug. 

It would be nice if this feature was properly implemented in ffmpeg

I think either because you are using the audio group id to map the variants or because you provide name attribute for the video streams too the name is not being handled properly (name isn’t defined for ext-stream-inf). As you say name is supposed to be a human readable description but it is used as a suffix index by hls muxer, you should edit the master playlist after it is written with another tool if you want to add it.
