• 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.

  


• FFmpeg return 'invalid argument' only for some runs, even tought is the same code

  20 septembre 2021, par Gustavo Marinho

  I have a code in python where i need to use FFmpeg to merge a audio and a video downloaded using pytube together :

  


          for video in p.videos:
            video.streams.filter(file_extension='mp4',resolution='480p')[0].download(parent_dir+'/mp4/processing/video')
            print(video.streams.filter(only_audio=True)[1].download(parent_dir+'/mp4/processing/audio'))

            subprocess.run([

                r'c:\FFmpeg\bin\ffmpeg', '-i',
                os.path.join(parent_dir+'/mp4/processing/video',video.streams.filter(file_extension='mp4',resolution='480p')[0].default_filename)
                ,'-i',
                os.path.join(parent_dir+'/mp4/processing/audio',video.streams.filter(only_audio=True)[1].default_filename),
                '-c:v','copy','-c:a','copy',
                os.path.join(parent_dir+'/mp4',video.streams.filter(file_extension='mp4',resolution='480p')[0].title+'.mp4')

            ])


  


  I tought the code was working perfectly, but in some cases, the FFmpeg returns "invalid argument", like this example :

  For some reason, the FFmpeg say that my output name is invalid, but i don't understand why, given that i ran the code multiple times before and it worked perfectly

  


  Thanks in advance, sorry for my bad english :3
