Is there a way to insert in a timed metadata or timed event into HLS content? For example, at 5 seconds into the movie, the player (Android exoplayer) can receive a timed metadata or timed event, so that the player can offer the user to skip the introduction.
So far, I used ffmpeg to take an MP4 movie and create an HLS format with fragmented mp4 segment.
ffmpeg -y \
-i Allied.mp4 \
-force_key_frames "expr:gte(t,n_forced*2)" \
-s 1280x720 \
-c:v libx264 -b:v 1500k \
-c:a copy \
-hls_flags single_file \
-hls_time 6 \
-hls_playlist_type vod \
-hls_segment_type fmp4 \
-hls_segment_filename "single_file.m4s" \
But now I need to insert some timed metadata or timed event in to it. What options does ffmpeg have that can support this?
