ffmpeg error: Could not write header for output file #0 (incorrect codec parameters ?): Muxer not found

Question

I am trying to segment a mp4 video file for HLS playback and I am getting the following error:

"Could not write header for output file #0 (incorrect codec parameters ?): Muxer not found"

Does anyone know what I am doing wrong?

input command:

sudo ffmpeg -y -i adwd.mp4 -vcodec copy -acodec copy -force_key_frames 30 -map 0  -f segment segment_list adwd.m3u8 -segment_time 10 -segment_format mpeg_ts -segment_list_type m3u8 segment%d.ts

Answer 1

The error message appears to indicate that it can't find the segment muxer. You can check if it is enabled with the following command:

ffmpeg -formats | grep segment

It should output something like this:

E segment         segment
E stream_segment,ssegment streaming segment muxer
