after that i am trying to write something o all ts file with this command

ffmpeg -i stream0.ts -vf  "drawbox=y=ih/PHI:[email protected]:width=iw:height=48:t=fill,  drawtext=text='Title of this Video':fontcolor=white" -c:v libx264 -c:a copy    ../video6/stream0.ts
ffmpeg -i stream1.ts -vf  "drawbox=y=ih/PHI:[email protected]:width=iw:height=48:t=fill,  drawtext=text='Title of this Video':fontcolor=white" -c:v libx264 -c:a copy    ../video6/stream1.ts
ffmpeg -i stream2.ts -vf  "drawbox=y=ih/PHI:[email protected]:width=iw:height=48:t=fill,  drawtext=text='Title of this Video':fontcolor=white" -c:v libx264 -c:a copy    ../video6/stream2.ts
ffmpeg -i stream3.ts -vf  "drawbox=y=ih/PHI:[email protected]:width=iw:height=48:t=fill,  drawtext=text='Title of this Video':fontcolor=white" -c:v libx264 -c:a copy    ../video6/stream3.ts
ffmpeg -i stream4.ts -vf  "drawbox=y=ih/PHI:[email protected]:width=iw:height=48:t=fill,  drawtext=text='Title of this Video':fontcolor=white" -c:v libx264 -c:a copy    ../video6/stream4.ts
