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 :


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]scale=w=1080:h=1920[t0];
[4:v]scale=w=1080:h=1920[t1];
[outv][t0]overlay=enable='between(t,6.6045,9.6335)'[out0];
[out0][t1]overlay=enable='between(t,12.5655,15.6165)'[out1];
[0:a][1:a][2:a]concat=n=3:v=0:a=1[audio]" 
-c:v libx264 -pix_fmt yuv420p -map [out1] -map [audio] -preset ultrafast output.mp4


I get success only with few videos. Most of the times the command execution never stops. It keeps on appending something to the output video file even for hours. Here is the output from console :

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

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.

Errors converting EXRs to mp4 with ffmpeg
3 février 2021, par GaryOI'm using ffmpeg 4.3.1 to convert some EXRs to mp4, with tone mapping for the extended range in the source and rec709 conversion for the mp4.


I'm using this command :


ffmpeg -pattern_type glob -framerate 24 -i 'frames/*.exr' -vf zscale=transfer=linear,tonemap=hable,zscale=transfer=bt709,format=yuv420p -c:v libx264 -r 24 -preset slow -crf 18 -pix_fmt yuv420p foo-tonemap-01.mp4


but it gives me this error :


Input #0, image2, from 'frames/*.exr':
 Duration: 00:00:00.08, start: 0.000000, bitrate: N/A
 Stream #0:0: Video: exr, gbrapf32le, 1920x1080 [SAR 1:1 DAR 16:9], 24 tbr, 24 tbn, 24 tbc
Stream mapping:
 Stream #0:0 -> #0:0 (exr (native) -> h264 (libx264))
code 3074: no path between colorspaces
Error while filtering: Generic error in an external library


What does that error "no path between colorspaces" mean ? Do I need to tell it what colorspace the EXRs are in (scene-linear RGB) or something ?
