• FFMPEG - Insert text MP4 and closed

  29 septembre 2015, par Celso Lopes

  I am using FFmpeg to insert text in a video. However I did not want it ENCODED The Full Video . Just as I want the text to be inserted at 20 seconds, then I want to stop coding. Since I’ll encode several videos a day.
  I just need to add the text and do NOT need to to read entire video.

  Next I use the command , only that it encodes the Full Video .

  ffmpeg -i original.mp4 -strict experimental -vf "drawtext=fontfile='/usr/share/fonts/truetype/dejavu/DejaVuSans-Bold.ttf':text='Liberado para Celso':x=500:y=10:fontsize=9" saida3.mp4

  I believe I don’t need to generate a MP4 as output, just that it inserts the text and be fast !

• How to merge .ts files from a DLINK security camera losslessly ?

  13 juin 2022, par anjchang

  I have >1000s of small .ts files from a DLINK camera of a theft that occured. I first tried to merge the ts files into bigger files so that I could look for the audio where the relevant event occurred. Then in Premiere I looked for the highest sustained audio peaks (it was someone using a saw to cut out a catalytic converter). Then, I isolated the relevant 200 files where things happened on the timeline. But now, I want to export the 20 minutes of the incident with the least compression (or no compression). Apparently Adobe Premiere can export the whole timeline containing these clips, but will compress them. I have not edited any of the files, so I don't want any rendering. I just want them strung together in a "well-known" format so I can send the files to the insurance company and authorities.

  


  I used an answer from here but there were audio gaps. Some of the files had no audio, causing the problem when I first merged the files with :

  


   for i in `\ls *.ts | sort -V`; do echo "file '$i'"; done >> mylist.txt;ffmpeg -f concat -i mylist.txt -c copy -bsf:a aac_adtstoasc video.mp4
