• ffmpeg "Requested output format 'decklink is not a suitable format'"

  9 février 2018, par user3104363

  I am trying to play a video using ffmpeg and decklink.
  I compiled ffmpeg from ffmpeg repo.
  I am working in ubuntu 16.04 lts.

  Here is my command :

  ./ffmpeg -err_detect ignore_err -threads 0 -re -i ./sample_1080_50i.ts -bufsize 1M -vf yadif -format_code Hi50 -f decklink -preroll 0.7 -pix_fmt uyvy422 'DeckLink Studio 4K'

  The result is :

  DeckLink Studio 4K: Invalid argument

  I think, this error is weird.
  I enabled decklink support with —enable-decklink, and I also check ffmpeg documentation decklink part.’decklink’ is used with -f option in every example.

  Then I check the command line, and I can’t find any error with the command.
  Do you have any idea what the problem is ?

  Thanks and best regards,

• add subtitle to video created from mp3 file and an image using ffmpeg

  1er février 2018, par no name

  I have a simple image and an mp3 file all I want to do is to add a lyrics to this mp3 file in a video as an output with fade out style.
  so i used this command to do so from this this blog
  

  ffmpeg -loop 1 -y -i test.jpg -i test.mp3 -vf subtitles=”f=test.srt:force_style=’FontName=Arial,FontSize=14″ -shortest test1.mp4

  when i used this command i got this eror

  At least one output file must be specified

  iam using windows 10, last version of ffmpeg, so what makes this problem. also how to make the style of the lyrics to be something like fade in/out and so on. if it’s possible
  Thanks in advance.
  update
  when i use this command

  ffmpeg -loop 1 -y -i test.jpg -i test.mp3 -vf "subtitles=test.srt:force_style='FontName=Arial,FontSize=14'" -shortest test1.mp4

  it give me this error

  Conversion failed!

  i searched this error and i found a solution by add this part before output file so the final command is

  ffmpeg -loop 1 -y -i test.jpg -i test.mp3 -vf "subtitles=test.srt:force_style='FontName=Arial,FontSize=14'" -shortest -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" test1.mp4

  i got no error and it worked but the output video not contains any lyrics which i added

  Update
  
  last thing i tried and it works first i use this command to convert the image and mp3 file to a mp4 video

  ffmpeg -loop 1 -i test.jpg -i test.mp3 -shortest -acodec copy -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" video.mp4

  but this command take a long time to process to convert mp3 of 2:55 minute it with image.
  then i start to add lyrics or subtitle using this command

  ffmpeg -i video.mp4 -vf "subtitles=test.srt:force_style='FontName=Arial,FontSize=14,PrimaryColour=&H0000ff&'" -c:a copy output.mp4

  this worked perfect and give the output but it take a long time to process i don’t know if this normal.
  now last thing how can i set the style of the subtitle so it be fade out or something

• Bad video quality and only 3 fps

  25 juillet 2019, par ApplowPi

  There are a few things wrong with the quality of the output file when I run this command.

  arecord -d 0 -r 48000 -c 2 -f S16_LE -t wav -D sysdefault:CARD=tc358743 | avconv -t 0 -i pipe:0 -f v4l2 -i /dev/video0 -c:v libx264 -r 30 -acodec aac -ar 48000 -vcodec flv -strict experimental -y -f flv test.flv

  The audio seems okay at the moment but, if I’m reading it correctly (at the very bottom of the output below), the fps is about 3 and the quality is at 31, which I understand is the worse. This is the output during the process.

  I’m looking to get 30 fps (ideally 60 if possible).

  I’m pretty new to this, any help would be great. Thanks in advance.
