• Run "scrcpy" Commands And Throws Error "libopenh264.so.7 is missing" / "openh264 disabled"

  7 mai 2024, par 息子運命

  I try to run scrcpy command like what I did before, and proved if it's worked not just once.

  


  scrcpy -m 540 -S


  


  but after re-installing my OS and use Fedora OS with dnf package manager, I got errors with output below.

  


  WARN: Demuxer 'audio': stream explicitly disabled by the device
WARN: [FFmpeg] libopenh264.so.7: cannot open shared object file: No such file or directory: libopenh264.so.7 is missing, openh264 support will be disabled
ERROR: Demuxer 'video': could not open codec
ERROR: Demuxer error
[server] INFO: Device screen turned off


  


  Seems I got a problem here because [FFmpeg] libopenh264.so.7 is missing and it cause openh264 support disabled.

  


• ffmpeg generates "unconnected output" error using -filte_complext [closed]

  25 juillet 2023, par ConiferRod

  I'm trying to combine the rtsp streams of 4 Wyze cameras into a single stream and pipe the result into ffplay (Windows 11). My -filter_complex generates an 'unconnected output' error.

  


  The command :
"C :\Program Files\ffmpeg\ffmpeg.exe" ^
-i rtsp ://user:password@10.0.0.239/live ^
-i rtsp ://user:password@10.0.0.181/live ^
-i rtsp ://user:password@10.0.0.251/live ^
-i rtsp ://user:password@10.0.0.252/live ^
-filter_complex "[0:v][1:v][2:v][3:v]xstack=inputs=4:layout=0_0|w0_0|0_h0|w0_h0[v]" -map '[v]' ^
| "C :\Program Files\ffmpeg\ffplay.exe" -

  


  The error :
[fc#0 @ 000001f45c979d40] Filter xstack:default has an unconnected output
Error : Invalid argument
fd: : Invalid data found when processing input 0KB sq= 0B f=0/0

  


• Calling ffmpeg from Java calling command line/ shell script throws "Trailing garbage after a filter" Error

  Calling ffmpeg from Java throws "Trailing garbage after a filter" Error

  


  I tried to call from Java application command string over dockerized ffmpeg, same result.

  


  docker run --rm  -v sample-test:/config linuxserver/ffmpeg  -loop 1 -t 5 -i  config/1.jpeg  -loop 1 -t 5 -i  config/3.jpeg  -y -filter_complex "[0:v]fade=t=out:st=4:d=1[v0];  [1:v]fade=t=in:st=0:d=1,fade=t=out:st=4:d=1[v1];  [v0][v1]concat=n=2:v=1:a=0,format=yuv420p[v];" -map "[v]"  config/output/video_java.mp4


  


  My goal is to run such a query from Java application

Runtime.getRuntime().exec(String.format("/bin/sh -c " + ffmpegCommand));
