avconv_filter : Use full named options
10 septembre 2015, par Vittorio Giovaraavconv_filter : Use full named options
This introduces a slight timebase computation difference in zmbv-8bit
fate test. This is expected since the new options are double instead
of ints, and the additional precision skews the results in a non
meaningful way. -

Piping ppm files to ffmpeg to create movie in c++
15 août 2015, par chasep255I want to create a movie of a zoom on the Mandelbrot set. To do this I want to create image data in the ppm format and then pipe it into ffmpeg using popen. The following command works if I first save the ppm to my disc and then run ffmpeg through the terminal.
ffmpeg -i out.ppm -r 1/5 out.mp4
Here is what I am trying to do in code.
FILE* p = popen("ffmpeg -i /dev/stdin -r 1/5 out.mp4", "w");
ppm_pipe(p, pix_buffers[0], w, h);
fclose(p);
...
void ppm_pipe(FILE* f, unsigned char* pix, int w, int h)
{
assert(fprintf(f, "P6 %d %d 255\n", w, h) > 0);
size_t sz = 3 * (size_t)w * (size_t)h;
assert(fwrite(pix, 1, sz, f) == sz);
}I get the following error message.
