How to specify a non default type when calling a FFmpeg library using ctypes
1er août 2013, par Jim RambergI am calling an FFMPEG library called avformat_alloc_context() that returns a pointer to type AVFormatContext. The structure AVFormatContext is defined in the avformat library.
Obviously ; this is not one ctypes default types and results in an error when I try to pass a reference to it to another ffmpeg library further down in my code.
Is there a way to add in the the classes defined inside of the library ? I read through what documentation I could find online and was not able to find a good answer to this question.

How to set the value of an arbitrary pixel in ffmpeg ?
14 mai 2017, par NebI want to modify the rgb value of each pixel inside ffmpeg.
I need to implement the following function :
A[x + expr_1][y] = expr_2
where x and y are the current sampled pixel, A is the input frame whose pixel need to be modified and expr_1, expr_2 are two independent expressions.
I tried using the geq filter but it seems there no way to set the value of a pixel other than from that currently sampled. For istance, the function p(x,y) only returns the value of the pixel at the specified location, but doesn’t allow to set a value for that pixel. In other word, ffmpeg seems allowing only something like :
A[x][y] = expr
Is there a way to tell ffmpeg to set the value of a specific pixel ?
Thanks for your time.
