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

[Alessandro Molon]

Hi Guys,

Does anybody know If there is a way to set a specific value of NAME in EXT-X-MEDIA with the HLS muxer?

My command line is:

/usr/src/ffmpeg-4.2.2/ffmpeg -hwaccel cuvid -c:v h264_cuvid -i INPUT.ts \
-filter_complex "[0]split=5[inter-SD][inter-SDh][inter-FHD][inter-HD][inter-SDq];[inter-SD]hwupload,scale_npp=640:480:format=yuv420p,hwdownload[vout-SD];[inter-SDh]hwupload,scale_npp=480:320:format=yuv420p,hwdownload[vout-SDh];[inter-FHD]hwupload,scale_npp=1920:1080:format=yuv420p,hwdownload[vout-FHD];[inter-HD]hwupload,scale_npp=1280:720:format=yuv420p,hwdownload[vout-HD];[inter-SDq]hwupload,scale_npp=320:240:format=yuv420p,hwdownload[vout-SDq]" \

-hls_segment_filename alextest1/%v/chunk-%08d.ts alextest1/%v/playlist.m3u8

The comman more or less does what I need,
but the NAME value is always set as "audio_1, audio_2...." and so on.

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="group_HIGH_BR",NAME="audio_0",DEFAULT=YES,LANGUAGE="ENG",URI="AEN128/playlist.m3u8"

#EXT-X-STREAM-INF:BANDWIDTH=1460800,RESOLUTION=1280x720,CODECS="avc1.640029,mp4a.40.2",AUDIO="group_HIGH_BR"

#EXT-X-STREAM-INF:BANDWIDTH=400400,RESOLUTION=320x240,CODECS="avc1.4d400d,mp4a.40.2",AUDIO="group_LOW_BR"
Video_SDq/playlist.m3u8

I would like to be able to set the value with something else, eg. the language (NAME="English" or NAME="French") but I didn't find any information about that.

Thanks in advance
