  • Quantization property in CUVID

    19 octobre 2016, par mkreddy

    Please correct me if my understanding was wrong regarding qscale in ffmpeg.

    In ffmpeg H264 decoder has qscale_table which hold the values of qp for each macro block.

    Is there any such table/matrix in CUVID to know the qscale values ? If not, please suggest me how can I construct one such matrix for each macro block.

    Thanks in advance.

  • FFmpeg - How to scale and then drawtext ?

    19 janvier 2015, par vanderjas

    I’m trying to scale and crop a video and then apply some text over the top.

    I’m able to achieve each of these successfully using the following filters :

    Scale & Crop

    -vf scale=-1:640,crop=640:640:0:0

    Draw Text

    -vf drawtext="fontfile=Gotham-Book.ttf: text=TextHere:fontsize=72:fontcolor=gray@0.25:x=10:y=10”

    I presume I need to use some kind of filter complex but I am not having any luck.

    Can anyone help ?

    Thanks in advance !

  • Superimpose audio track on plot animation

    17 février 2023, par Antoine101

    I plot a matrix in a standard matplotlib figure with imshow. Each matrix is the result of a signal processing calculation on a time signal snapshot (0.2s). I plot each snapshot one after the other (the signal is several seconds long) in a loop and record the animation with FFMPegWriter, setting the FPS so that it matches real time. The output is an MP4 file.

    


    Now, I'd like to add a soundtrack on top of it, of the time signal that was used to calculate the matrices.

    


    How would you do that ? I scrolled a lot but didn't find any suitable solution.
Any idea of libraries or packages ?

    


    Many thanks in advance.
