• MPV -when playing two identical rtsp streams at the same time, one of them stops playing

  15 novembre 2022, par xzf361

  I utilize mpv to play rtsp stream, when I execute the following command for the first time, rtsp plays fine.
mpv rtsp ://192.168.1.217:554/stream1
When I execute the same command above for the second time, the first playback window will stop playing, but the second playback window will play normally.
why is that ?

• python suggests ffmpeg installation when it is installed

  17 janvier 2021, par FNTE

  I have a problem related to the bar_chart_race python package. I have installed ffmpeg but when I execute my code, I get :

  


  You do not have ffmpeg installed on your machine. 
Download from here: https://www.ffmpeg.org/download.html.


  


  I know that I have used this package before and it was all good. I have installed ffmpeg version :

  


  ffmpeg -version
ffmpeg version 4.2.3 Copyright (c) 2000-2020 the FFmpeg developers
built with gcc 9.3.1 (GCC) 20200523


  


  Do you know what I can do ? I have bin folder in path.

  


• Laravel FFMpeg - FFMpeg cannot edit existing files in-place

  28 septembre 2020, par wlaskovic

  After I wanted to upload a video in the queue was returned a failed job.

  


   [2020-09-25 13:24:25][125] Processing: App\Jobs\ConvertVideoForStreaming <br /> [2020-09-25 13:24:26][125] Failed:     App\Jobs\ConvertVideoForStreaming&#xA;

  


  So I've took from the DB failed_jobs table the response and run the following :

  


    C:\ffmpeg\bin\ffmpeg.exe -y -i "C:\wamp64\www\laravel-stream\storage\app/public\WF3UL8fJTSE7BMxa.mp4" -threads 12 -vcodec libx264 -acodec libmp3lame -b:v 500k -refs 6 -coder 1 -sc_threshold 40 -flags +loop -me_range 16 -subq 7 -i_qfactor 0.71 -qcomp 0.6 -qdiff 4 -trellis 1 -b:a 128k -vf "[in]scale=720:360 [out]" -pass 1 -passlogfile "C:\Users\wlask\AppData\Local\Temp\ffmpeg-passes5f6dd36a4519fd1fev/pass-5f6dd36a452c9" "C:\wamp64\www\laravel-stream\storage\app/public\WF3UL8fJTSE7BMxa.mp4"


  


  Which returned the following :

  FFmpeg cannot edit existing files in-place.

  


  


  This was returned after i've run the command from DB failed jobs table return.

  


  How should I solve this ?
