  • Set correct start time of ts-file using ffmpeg

    9 octobre 2020, par Daniel

    I am splitting up a video into multiple 10 second ts-parts (mpeg-ts format) using ffmpeg on windows.

    



    To create the 2nd part (that starts at 10 seconds into the video and ends at 20 seconds into the video) :

    



    ffmpeg -i sample.avi -ss 00:00:10 -to 00:00:20 -vcodec libx264 -acodec aac -vf scale=426:-1 out1.ts


    



    But when i check the file using ffprobe it says :

    



    Duration: 00:00:10.02, start: 1.458667, bitrate: 359 kb/s


    



    So the duration is ok but the start time is incorrect. Is it anyway i can use ffmpeg to correct it to 00:00:20 ?
The best solution would of course to be able to set the correct start time in my first command where i take out the 10 second part but i would also be ok with running a 2nd command to fix the time.

    



    Is this possible ? Cant find any documentation and all examples i found are not for my exact problem and don't seem to work then i play around with them.

  • 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.
