• Fade Video-Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

  27 octobre 2018, par varmashrivastava

  I am using below command to add Fade In Fade Out effect to my video

  {"-y", "-ss", "" + startMs / 1000, "-t", "" + (endMs - startMs) / 1000, "-i", inputPath, "-acodec", "copy", "-vf", "fade=t=in:st=0:d=5,fade=t=out:st=" + String.valueOf((endMs - startMs) / 1000 - 5) + ":d=5", outputPath};

  I received below error-

  Why is causing this error in above command ?Any help will be welcome.

• Is ffmpeg using a buffer ? Why arent the filename and drawtext times matching ?

  6 octobre 2018, par Ian Rubenstein

  I am using ffmpeg to

  1) capture images from a webcam as jpeg with the timestamp in the filename and as an overlay with drawtext

  ffmpeg -s 1920x1080 -framerate 20 -i /dev/video1 -f image2 -ss 8 -s 1920x1080 -qscale:v 1 -r 1 -strftime 1 -vf setpts=.2*PTS, drawtext=fontfile=/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf: text='%{localtime\:%Y-%m-%d_%T}': fontcolor=white: fontsize=24: box=1: boxcolor=black@0.5: boxborderw=5: x=(w-text_w)*.04: y=(h-text_h)*.96 /home/ian/netdrives/antares/Pictures/plant_lapse/ir/20181004/plant.%Y%m%d_%H%M%S.jpeg

  2) combine the images into a timelapse video

  C:/Users/Ian/apps/ffmpeg/bin/ffmpeg -f concat -safe 0 -i processingfilelist.ir_20181004.txt -c:v h264_nvenc -rc constqp -qp 38 -s 1920x1080 -filter:v format=yuv420p,fps=60,scale=iw/1.5:-1,yadif=0:-1:0,hqdn3d plant_lapse_ir_20181004_074451_dusk.mp4

  Its generally working, but I noticed the filenames are one frame ahead of the timestamp shown in the overlay.

  Example Image - Im not smart enough to know which is the right time, just to know that I’d like them to match. Any ideas why they don’t ?

  there is a strange message.
  ’malloc of size 152432416 failed’
  I think this is memory problem but I have no idea to solve this problem.
