  • Convert Cairo ImageSurface to PIL Image object

    31 octobre 2015, par Simon

    I’m trying to convert a Cairo ImageSurface to a PIL Image object so it can be passed to an ffmpeg pipe.

    What I have so far is :

    where svgstr holds the SVG data of the image as a string.

    img = cairo.ImageSurface(cairo.FORMAT_ARGB32, 386,1080)
    
ctx = cairo.Context(img)
    

    
#render the svg as a png
    
handle= rsvg.Handle(None, svgstr)
    
handle.render_cairo(ctx)
    

    
imgPIL = Image.frombuffer("RGBA",( img.get_width(),img.get_height() ),img.get_data(),"raw","RGBA",0,1)
    

    
img44 = imgPIL.convert("RGBA")
    
img44.save(p.stdin,"PNG")

    If I save the image to file rather than passing it to the pipe, I get some version of grayscale. When passed to the pipe it gives "IOError : [Errno 32] Broken pipe"

    Ultimately I’m just trying to convert SVG data to some sort of object that I can pass to the ffmpeg pipe to concatenate images into a video without having to save the images to disk first.

  • ffprobe returning video stream data twice

    15 novembre 2015, par GeorgeKat

    I’m trying to return specific values from ffprobe :

    ffprobe -v error -select_streams V:0 -show_entries stream=index,width,height,sample_aspect_ratio,display_aspect_ratio:format=duration  -of default=noprint_wrappers=1:nokey=1 test.MTS

    The stream values in the output are repeated :

    0
    
1920
    
1080
    
1:1
    
16:9
    
0
    
1920
    
1080
    
1:1
    
16:9
    
116.640000

    The format value is not repeated.
    If I strip the printer values to see what’s going on :

    ffprobe -v error -select_streams V:0 -show_entries stream=index,width,height,sample_aspect_ratio,display_aspect_ratio:format=duration  test.MTS

    I see a section called [PROGRAM] with stream 0 repeated within it :

    [PROGRAM]
    
[STREAM]
    
index=0
    
width=1920
    
height=1080
    
sample_aspect_ratio=1:1
    
display_aspect_ratio=16:9
    
[/STREAM]
    
[/PROGRAM]
    
[STREAM]
    
index=0
    
width=1920
    
height=1080
    
sample_aspect_ratio=1:1
    
display_aspect_ratio=16:9
    
[/STREAM]
    
[FORMAT]
    
duration=116.640000
    
[/FORMAT]

    Can someone please help me to return only the video stream 0 values once ?

  • FFmpeg 16:9 Aspect ratio

    29 mai 2020, par Satish Kumar

    Find the Image attachedI have a video of resolution 1920 x 1080, but it is cropped with black in all sides. I found the crop values as 1440:720:240:208.

    



    But when i apply crop with (1440:720:240:208.), the output video loses some portion of videos along the four sides, which is actually present in original input video.

    



    I want to remove only the black border on all sides, but the output video should cover the 16:9 aspect ratio without losing the actual play area as in input (original) video

    



    pl let provide the ffmpeg syntax for the same.
