  • Using FFMPEG to create animated GIF from series of images and insert text for each image

    11 janvier 2021, par mwcmwc

    I am generating an animated gif from a series of png's labeled img_00.png, img_01.png, etc. I want to insert text to the top right corner of the animated gif for each frame that is generated from the png to display some specific information. For example say I have 3 pngs, img_00, img_01, and img_02...what I want from the gif is :

    


    For frame generated from img_00, display "This is from img_00".
For frame generated from img_01, display "This is from img_01".
For frame generated from img_02, display "This is the last image generated from img_02 !".

    


    So far I have been messing around with drawtext option (assuming framerate=1) :

    


    ffmpeg -f image2 -framerate 1 -i img_%02d.png -filter_complex "drawtext=enable='between(t,0,1)':text='word1':fontsize=24:fontcolor=white:x=w-tw:y=0,drawtext=enable='between(t,1,2)':text='word2':fontsize=24:fontcolor=white:x=w-tw:y=0" out.gif


    


    But I am getting "word1" and "word2" overlapped on top of each other. Is there a better way of doing this or someway to fix drawtext so the overlap doesn't happen ?

    lavu : fix memory leaks by using a mutex instead of atomics

    The buffer pool has to atomically add and remove entries from the linked
    
list of available buffers. This was done by removing the entire list
    
with a CAS operation, working on it, and then setting it back again
    
(using a retry-loop in case another thread was doing the same thing).
    

    This could effectively cause memory leaks : while a thread was working on
    
the buffer list, other threads would allocate new buffers, increasing
    
the pool’s total size. There was no real leak, but since these extra
    
buffers were not needed, but not free’d either (except when the buffer
    
pool was destroyed), this had the same effects as a real leak. For some
    
reason, growth was exponential, and could easily kill the process due
    
to OOM in real-world uses.
    

    Fix this by using a mutex to protect the list operations. The fancy
    
way atomics remove the whole list to work on it is not needed anymore,
    
which also avoids the situation which was causing the leak.
