Thanks Mortiz, Here's my installation:
ffmpeg version 3.3.4 Copyright (c) 2000-2017 the FFmpeg developers I solved the issue using brew installation on mac. The zmq documentation seems to be very sparse and not detailed. Could you please help me with the following problem. I need to change the layout of 2x2 video mosaic using zmq. In the static case, I create a 2x2 mosaic video using: *ffmpeg \-i in1.mov -i in2.mov -i in3.mov -i in4.mov \-filter_complex " \nullsrc=size=640x360 [base]; \[0:v] setpts=PTS-STARTPTS, scale=320x180 [upperleft]; \[1:v] setpts=PTS-STARTPTS, scale=320x180 [upperright]; \[2:v] setpts=PTS-STARTPTS, scale=320x180 [lowerleft]; \[3:v] setpts=PTS-STARTPTS, scale=320x180 [lowerright]; \[base][upperleft] overlay=shortest=0 [tmp1]; \[tmp1][upperright] overlay=shortest=0:x=320 [tmp2]; \[tmp2][lowerleft] overlay=shortest=0:y=180 [tmp3]; \[tmp3][lowerright] overlay=shortest=0:x=320:y=180" \-c:v libx264 output.mov* Now I need to change the red parameters using zmq. Therefore I re-write above as: *ffmpeg \-i in1.mov -i in2.mov -i in3.mov -i in4.mov \-filter_complex " \nullsrc=size=640x360 [base]; \[0:v] setpts=PTS-STARTPTS, scale=320x180 [upperleft]; \[1:v] setpts=PTS-STARTPTS, scale=320x180 [upperright]; \[2:v] setpts=PTS-STARTPTS, scale=320x180 [lowerleft]; \[3:v] setpts=PTS-STARTPTS, scale=320x180 [lowerright]; \[base][upperleft] overlay=shortest=0 [tmp1]; \[tmp1][upperright] overlay=shortest=0:x=320 [tmp2]; \**[tmp2] * *[lowerleft] overlay=shortest=0:y=180 [tmp3]; \[lowerright] zmq, [tmp3] overlay=shortest=0:x=320:y=180" \-c:v libx264 output.mov* *But I cannot get access to these parameters using zmqsend? I tried different messages like:* echo Parsed_overlay_0 x 440 | zmqsend echo Parsed_overlay_1 x 440 | zmqsend I appreciate your helps in advance, Kamal On Sun, Oct 15, 2017 at 4:29 PM, Moritz Barsnick <[email protected]> wrote: > On Sun, Oct 15, 2017 at 15:17:00 -0400, kamal shadi wrote: > > Could anybody help me how to install zmq libraries for ffmpeg?
