  • How to load/dump a raw video data into AvFrame structure pointer by using ffmpeg api function

    4 octobre 2016, par Harikrishna

    I want to write an application for encoding raw (yuv) video file data by using ffmpeg api functions instead of using a command.

    So for this, I need to use avcodec_encode_video2 function to encode raw video data and before calling this function all required configurations and video data should be fill on the AVCodecContext and AvFrame structure pointers.

    Can anyone guide me that how can I load this raw video data on AvFrame by using ffmpeg api function ?

    Thank you in advance.

  • FFMpeg : clipping rectangle for drawtext

    6 mai 2019, par rcpinheiro

    I’m trying to overlay a caption inside a box (or graphic) over a video. The caption is always a one-liner and starts always at the same coordinates and time. The problem is when the caption is very big and falls outside the desired clipping rectangle.

    Here’s a sample (w/o clipping rectangle) :

    ffmpeg -i input.mp4 -vf "drawbox=x=40:y=620:w=1200: h=80:color=#000080@0.8:t=fill [first];\
    
[first] drawtext=fontfile=font.ttf: text='Some text in one line that could be very big':x=60:y=640:fontsize=40:fontcolor=#f0f0f0@0.6 [out]" \
    
-vcodec libx264 -crf 27 -preset ultrafast -strict -2 output.mp4

    Is there a way to crop the caption without using the subtitle filter ?
    Thanks in advance !
