• ffmpeg and hardcoding subtitles

  8 avril 2015, par Adin Gill

  I have a command like so

  ffmpeg -i "F:\Filebotted\Rail Wars\Season 1\Rail Wars.S01E07(7).You Look Good in That. 1080p.mkv" -map 0:0 -map 0:1 -b:v 750k -b:a 128k -c:v libx264 -c:a mp3 -ac 2 -filter_complex "subtitles=F:\Filebotted\Rail Wars\Season 1\Rail Wars.S01E07(7).You Look Good in That. 1080p.mkv,scale=-1:360" "C:\Users\Adin\Desktop\Testy mc test\Rail Wars.S01E07(7).You Look Good in That. 1080p.mkv"

  Yes it is long but unfortunatly ffmpeg chucks a hissy fit and spits out the following

  [subtitles @ 00000000050ce7c0] Unable to parse option value "FilebottedRail Wars
  
  Season 1Rail Wars.S01E07(7).You Look Good in That. 1080p.mkv" as image size

  gs 'F:FilebottedRail WarsSeason 1Rail Wars.S01E07(7).You Look Good in That. 1080
  
  p.mkv'
  
  Error configuring filters.

  It works just fine when the file is in the same folder as ffmpeg (I found out that it doesn’t like ’ or - in the filename, but I just spent an hour trying to work out the issue with no avail.

  Any help will be appreciated :)

• FFMPEG Overlay 1080X1920 video over 1280X720 video at a particular vertical position

  9 mai 2019, par CRAIG

  I have a 1080X1920 (vertical) video with alpha channel with a blank spot 500px north of the bottom. This blank spot is 1080X607.

  I have a 1280X720 sized video I want to position in that spot, so the 1280 video will have to be sized down to 1080 wide and then positioned 500px from the bottom and UNDER the video on top.

  This is what I currently have, but it is failing beautifully.

  /usr/local/bin/ffmpeg  -i 1080x1920.mov -i 1280x720.MOV 
  
    -filter_complex "[1][0]overlay=main_w-overlay_w-0:main_h-overlay_h-500" 
  
    -c:v libx264 -profile:v high444 -pix_fmt yuv420p -level 3.1 -y  final.mp4

• What does “has_b_frames” mean in FFprobe output ?

  18 mai 2019, par Sunil Kumar

  I am checking a video file using ffprobe to findout if a video file has any b_frames or not, i can see ffprobe output shows “has_b_frames=0" , “has_b_frames=1" and “has_b_frames=2" when i check for different video files.

  index=0
  
  codec_name=h264
  
  codec_long_name=H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10
  
  profile=Main
  
  codec_type=video
  
  codec_time_base=1001/60000
  
  codec_tag_string=avc1
  
  codec_tag=0x31637661
  
  width=1080
  
  height=1920
  
  coded_width=1088
  
  coded_height=1920
  
  has_b_frames=1

  “has_b_frames=0" means there are no B frames present in video file ?

  can someone tell me what these values indicates,
