Piping ffmpeg output into ffplay stdin with boost
21 décembre 2020, par botiapaI'm trying to pipe the output of an ffmpeg process into an ffplay process (Sort of like a playback). My problem is the following : If I copy the output character by character (by character I mean
char
) it works correctly, other than it consuming a whole lot of cpu power. However when I try to pipe chunks into it (by using a buffer), ffplay for some reason doesn't even recognize the input.

bp::ipstream iso;
bp::ipstream ise;
bp::opstream in;
 
bp::child ffmpeg(bp::search_path("ffmpeg"), bp::args({"-loglevel", "quiet", "-f", "pulse", "-i", "default", "-f", "wav", "-bitexact", "-nostdin", "-"}), bp::std_out > iso, bp::std_err > ise);
bp::child ffplay(bp::search_path("ffplay"), bp::args({"-loglevel", "verbose", "-nodisp", "-f", "wav", "-i", "-"}), bp::std_in < in, bp::std_out > bp::null);



Here are the 2 code snippets for comparison :


Here it is copying
char
bychar


while(ffmpeg.running()) {
 char c;
 c = iso.get();
 in << c;
}



And here it is copying with the help of a buffer


char buffer[1024];
while(ffmpeg.running()) {
 iso.get(buffer, 1024);
 in << buffer;
}



I can provide ffplay output if necessary, however I didn't see any errors or things like that.
