FFMpeg - Overlay not being shown when enable=between parameter is added
19 août 2020, par Khawar RazaI am using below command to add transitions effect between videos using overlays such that when one videos is about to finish, the overlay gets visible. Before showing overlays, I have to add padding and concatenate videos make one single video and then display overlays. :


ffmpeg 
-i input1.mp4 
-i input2.mp4 
-i input3.mp4 
-i transition1.mp4 
-i transition2.mp4 
-filter_complex 
"[0:v]pad=width=1080:height=1920:x=(1080-iw)*0.5:y=(1920-ih)*0.5:color=black[video0];
[1:v]pad=width=1080:height=1920:x=(1080-iw)*0.5:y=(1920-ih)*0.5:color=black[video1];
[2:v]pad=width=1080:height=1920:x=(1080-iw)*0.5:y=(1920-ih)*0.5:color=black[video2];
[video0][video1][video2]concat=n=3:v=1:a=0[outv];
[3:v]colorkey=0x00d800:0.1[t0];
[t0]scale=w=1080:h=1920[tr0];
[4:v]colorkey=0x00d800:0.1[t1];
[t1]scale=w=1080:h=1920[tr1];
[outv][tr0]overlay=0:0:enable='between(t\,7\,9)'[out0];
[out0][tr1]overlay=0:0:enable='between(t\,12\,15)'[out1];
[0:a][1:a][2:a]concat=n=3:v=0:a=1[audio]" 
-vsync 0 -c:v libx264 -pix_fmt yuv420p -map [out1] -map [audio] -preset ultrafast output.mp4


But above command does not show any overlay video. If I remove enable=between(t, start, end) from overlay parameters, all the overlay gets displayed at video start. I am very beginner to video editing and to FFMpeg. Can anybody guide me what I am doing wrong here ?

ffmpeg command execution never stops
19 août 2020, par Khawar RazaI am trying to concatenate 3 videos of different resolutions and overlaying 2 videos as transition effects(though the chroma key color removal is not yet implemented) between videos using below command :

Live streaming Channel Multiview used ffmpeg X11grab and shaka packager
18 août 2020, par jgkim0518I have been trying to live stream channel multiview used xvfb, firefox, vlc, ffmpeg and shaka packager.
1). Making virtual display used Xvfb.
2). Popping up a web page used fireforx on 1).
3). Drawing nine video(each channel) used vlc plugin on 2).
4). Capturing 2) used ffmpeg library, x11grab.
5). Transcoding 4) to FHD(HEVC)+10 Audio(each channel sound + dummy), FHD(H.264)+no sound, HD(H.264)+no sound, SD(H.264)+no sound, nHD(H.264)+no sound
6). packaging 5) used Shaka Packager


This is my command. shell script

keep getting a similar message


This is played on vlc. this is duration 10 sec. but I want to live streaming duration 5 under.
cuda, framerate, GOP size and bitrate are fixed.


I know that is inefficient. but now, I have to live stream channel multiview duration 5 under. How can I achieve ? please help me.
