• How to seal subtitle on the video permanently ? ffmpeg

  10 octobre 2017, par Robert Choy

  I am able to add subtitle to my mp4 ; however, when i upload it on youtube, the subtitle is gone, disappeared.

  So i am asking if there is any method to make the subtitle on the video (forever, permanently, seal it, burn it, force everyone watch the video with subtitle, can’t even turn it off manually)

  ffmpeg -i video.mp4 -i subtitle.srt -c copy -c:s mov_text -disposition:s:0 forced \
  
  permanently-subtitle-video-please.mp4

  i dont like the design of youtube subtitle, so i would love to upload my video + subtitle as one thing.

  sorry i a not an English native speaker, hope you understand what i am trying to ask. thanks

• FFmpeg v0.12 is not working for Angular 16

  30 septembre 2024, par Amrut Kumar

  Currently, I have tried integrating ffmpeg v0.12 for my angular 16 project. But it takes forever for the ffmpeg to load. It goes into infinite loop. My guess is that its unable to load the worker script due to incompatibility with Angular 16 dependencies and functionalities.
I have tried ffmpeg v0.12 in my angular 18 app and everything is working just fine. The same changes wont work for my angular 16 application.
To take a step further, I have downgraded ffmpeg version to 0.11 and its now working perfectly fine for my angular 16 app.
Have any of you faced similar issue as I have explained above ? If yes, what steps did you take to resolve it ?

  


  I tried loading ffmpeg v0.12 with angular 16 app and I was expecting it to load just fine as I was able to achieve this with angular 18 with totally similar code changes.

  


• How to get ffmpeg to fail if stdin stream has errors ?

  12 juin 2020, par Sagi Mann

  I've got some code that outputs rawvideo to ffmpeg via pipe, which then overlays a png over it. If the code exits with an error, ffmpeg keeps going forever, I don't know how to stop it :( Any ideas ? Here's an example :

  



  set -o pipefail

(echo "error!!"; exit 1) | \
ffmpeg -f rawvideo -c:v rawvideo -s 1280x720 -pix_fmt bgra -i - \
    -i my_icon.png \
    -filter_complex "[0][1]overlay=50:50" \
    out.mp4


  



  Note ffmpeg DOES show an error message, but still does not stop, stuck in 'frame 0' forever, with a strange time attribute e.g. time:-577014:32:22.77 :

  



      [rawvideo @ 0x563fc94427c0] Packet too small (8)
    Error while decoding stream #0:0: Invalid data found when processing input
    Finishing stream 0:0 without any data written to it.:32:22.77 bitrate=  -0.0kbits/s speed=N/A    
    frame=    0 fps=0.0 q=0.0 size=       0kB time=-577014:32:22.77 bitrate=  -0.0kbits/s speed=N/A
