I think you are a bit overambitious. You are very close to your solutions, but keep going in the wrong direction.

I think you ignored the very clear message: "Unable to open subtitles.srt". That file probably just isn't there. > [AVFilterGraph @ 0x2695c20] No such filter: 'drawtext:drawtext' > Error opening filters! That means the drawtext filter wasn't built into your ffmpeg binary.

Don't use that. ffmpeg's download page points to way more recent static builds here: http://johnvansickle.com/ffmpeg/ > (ffmpeg)aameer@falcon:~/Documents/projects/ffmpeg$ ./ffmpeg -threads 4 -i > "input_sintel_trailer_720p.mp4" -profile:v baseline -level 4.0 -vf > scale="trunc(360*a/2)*2:360, subtitles='subtitle.srt'" -start_number 0 > -hls_time 10 -hls_list_size 0 -f hls videos/4444/index_4444_360_.m3u8 [...] > Could not write header for output file #0 (incorrect codec parameters ?): No > such file or directory "No such file or directory" tells me that the directory where you want to place your output file videos/4444/index_4444_360_.m3u8 does not exist. Do an "mkdir" first, like in your script. And from one of your comments in that thread: > gives me a syntax error: > (ffmpeg)aameer@falcon:~/Documents/projects/ffmpeg$ ffmpeg -threads 4 -i > "input_sintel_trailer_720p.mp4" -profile:v baseline -level 4.0 -vf > "scale=-2:360,drawtext="fontfile=/path/to/font.ttf:fontcolor=white:fontsize=30:text='Your > Text':x=(W-tw)/2:y=H-th-30"" -start_number 0 -hls_time 10 -hls_list_size 0 > -f hls videos/4444/index_4444_360_.m3u8 > bash: syntax error near unexpected token `(' You have a quoting issue. E.g. you are using duplicate '"' marks, some of those need to go away. I think instead of this: -vf "scale=-2:360,drawtext="fontfile=/path/to/font.ttf:fontcolor=white:fontsize=30:text='Your Text':x=(W-tw)/2:y=H-th-30"" you need this: -vf "scale=-2:360,drawtext=fontfile=/path/to/font.ttf:fontcolor=white:fontsize=30:text='Your Text':x=(W-tw)/2:y=H-th-30" You see, you are tripping over very fundamental things. You need to read those messages with more attention to detail.
