3 avril 2018, par roomyI follow the page Create a mosaic out of several input videos to merge videos. But,I got poor video quality. How can I get the video same as the original.
ffmpeg
-i 1.flv-i 2.flv -i 3.flv -i 4.flv
-filter_complex "
nullsrc=size=640x480 [base];
[0:v] setpts=PTS-STARTPTS, scale=320x240 [upperleft];
[1:v] setpts=PTS-STARTPTS, scale=320x240 [upperright];
[2:v] setpts=PTS-STARTPTS, scale=320x240 [lowerleft];
[3:v] setpts=PTS-STARTPTS, scale=320x240 [lowerright];
[base][upperleft] overlay=shortest=1 [tmp1];
[tmp1][upperright] overlay=shortest=1:x=320 [tmp2];

[tmp3][lowerright] overlay=shortest=1:x=320:y=240
"
-f flv rtmp://10.240.209.94:9999/live2And when I use rtmp ://** as video input.
Such as :ffmpeg-i rtmp://10.240.209.94:9999/live1 -i rtmp://10.240.209.94:9999/live1 -i rtmp://10.240.209.94:9999/live1 -i rtmp://10.240.209.94:9999/live1

-f flv rtmp://10.240.209.94:9999/live2It tells me :
Stream specifier ':v' in filtergraph description nullsrc=size=640x480 [base];[0:v] setpts=PTS-STARTPTS, scale=320x240 [upperleft];[1:v] setpts=PTS-STARTPTS, scale=320x240 [upperright];[2:v] setpts=PTS-STARTPTS, scale=320x240 [lowerleft];[3:v] setpts=PTS-STARTPTS, scale=320x240 [lowerright];[base][upperleft] overlay=shortest=1 [tmp1];[tmp1][upperright] overlay=shortest=1:x=320 [tmp2];[tmp2][lowerleft] overlay=shortest=1:y=240 [tmp3];[tmp3][lowerright] overlay=shortest=1:x=320:y=240 matches no streams.
Is that a bug ? but I use the newest ffmepg.
bugAnd I can only use the command :
ffmpeg -i rtmp://10.240.209.94:9999/live10 -vcodec copy -acodec copy -f flv output.flv
to transfer rtmp into flv,and then read flv video...
