  • how to run ffmpeg command(windows) in java

    26 mai 2020, par SAI GIRI CHARY AOUSULA

    I executed the below FFMPEG terminal command in command prompt successfully. But I am unable to execute this command in my java program. I can execute all other ffmpeg commands which doesn't have double quotation marks, in my java program. Here I have confusing only with double quotation marks("...").

    



    ffmpeg -i "concat:C:\\journalism\\videos\\vid1.ts|C:\\journalism\\videos\\vid2.ts" -c copy C:\\journalism\\videos\\output.mp4


    



    I can execute above in command prompt successfully. But I tried as below in my java code.

    



    Runtime.getRuntime().exec("C:\\ffmpeg\\bin\\ffmpeg -i 'concat:C:\\journalism\\videos\\vid1.ts|C:\\journalism\\videos\\vid2.ts' -c copy C:\\journalism\\videos\\output.mp4");


    



    Even I tried by replaced the double quotation marks("...") with single quotation marks('...'). But not succeeded.

    



    Can anyone please help me to get out of this issue...

    



    Thanks in advance...

    


  • matplotlib funcanimation save issue

    20 avril 2015, par Richie Abraham

    I have been trying some animation recently using matplotlib animations. It has been going great, i create an ffmpeg writer and save it as a video file. However i face an issue whenever the function that FuncAnimation calls returns more than one object.

    Below is a small snippet of my code base. When I return both im0 and im1, the video file created only has im1 , although the plt.show command works as expected ( showing both the videos ). If i return just a single im0, then it works as expected. IT also works as expected if i return both im0 and im1 with alpha=0.5.

    Can anyone shed some light on what is happening underneath the hood ?

    fig, ax = plt.subplots(1)
    
def animate(i):
    
    im0=ax.imshow(np.ma.masked_array(imgl[i][:,:,0], mask=get_blob(i)),cmap='cubehelix')
    

    
    im1=ax.imshow(imgl[(i-100)%len(imgl)][:,:,0],cmap='cubehelix')
    

    
    return [im1,im0]
    

    

    

    
ani = animation.FuncAnimation(fig, animate, frames=200,
    
                              interval=10, blit=True,repeat=False)
    
ani.save('ps.mp4', writer=writer)
    
plt.show()
