How to transcode HLS video (with .m3u8 subtitle file) for MPEG-DASH stream using FFMPEG ?
15 mai 2017, par Toan TranI’m trying to use ffmpeg to transcode a HLS
video.m3u8, which uses a.m3u8 subtitlefile, for MPEG-DASH streaming. The subtitle file has been defined in the master manifestvideo.m3u8but I receive only the video and audio, the subtitle doesn’t come along. What am I doing wrong ? Your help is very much appreciated.This is the command I used :
ffmpeg -i http://myserver_ip/video.m3u8 -vcodec libx264 -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1 -f flv rtmp://myserver_ip/dash/SampleVideoThis is my
