• Scroll one image top to bottom

  17 septembre 2018, par Cyber

  I am trying to scroll an image top to bottom like this video :
  https://youtu.be/8GCrrsiBLzs

  And here’s what I tried

  ffmpeg -loop 1 -t 24 -i "image.jpg" -filter_complex "color=000000:s=640x360[bg]; [bg][0]overlay=shortest=1:y='min(0,-(t)*26)'" -y out6.mp4

  But video didn’t created, ffmpeg close immediately and returns following results :

• FFMpeg conversions from avi to mp4 does not succeed with video for safari and IE browsers

  24 septembre 2020, par user27240

  The ffmpeg command below does convert mp4 file from avi file successfully for chrome browser, but with browsers such as 
safari and IE(I have not tested with other browsers yet.) I can not see the video and I only can hear the audio 
which simply means that safari and IE browsers do not accept the conversion of video from avi file to mp4 file.

  



  for i in /xxxxxx/xxxxxxx/xxxxxxx/*.avi; do ffmpeg -i "$i" -pix_fmt yuvj422p "/xxxxxx/xxxxxxx/xxxxxxx/$(basename "$i" .avi).mp4"; done    


  



  By the way, when I tried from flv file to mp4 with the same ffmpeg command both video and audio were successfully converted for chrome, safari, and IE.(I have not tested yet with others.)

  



  The avi file is the one I shot with my camera, and flv file is the one I downloaded from web.

  



  Can anyone please help me out ?

  



  The log file below is for the ffmpeg command from avi to mp4.(avi file is the one I shot with my camera)

• Video moves sideways when captured raw from camera and piped into ffplay

  21 septembre 2018, par peetonn

  I’m trying to capture video from the camera using ffmpeg (macOS 10.12) and pipe it for preview into ffplay using rawvideo and -v copy options :

  ffmpeg -f avfoundation -pixel_format 0rgb -framerate 25 -video_size 1280x720 -i "0" -map 0:v -c copy -f rawvideo - | ffplay -f rawvideo -video_size 1280x720 -pixel_format 0rgb -i -

  Video captures just fine, however, it constantly moves sideways (see screenshot attached). What might the issue here ?

  

  UPDATE Full ffmpeg log output :

  $ ffmpeg -f avfoundation -pixel_format 0rgb -framerate 25 -video_size 1280x720 -i "0" -map 0:v -c copy -f rawvideo - | ffplay -f rawvideo -video_size 1280x720 -pixel_format 0rgb -i -
