  • ffmpeg : video parameters incompatible with DNxHD [closed]

    26 octobre 2020, par Tombart

    I'm trying to convert mp4 to mov, however ffmpeg is having issues with the video conversion :

    


      Stream #0:0 -> #0:0 (h264 (native) -> dnxhd (native))


    


    I've tried several of suggested configuration without success :

    


      

    • -vcodec dnxhd -acodec pcm_s16le -pix_fmt yuv422p10 -r 24000/1001 -b:v 175M

      • 


    • -vcodec dnxhd -acodec pcm_s16le -pix_fmt yuv422p10 -r 25/1 -b:v 185M

      • 


    • -vcodec dnxhd -acodec pcm_s16le -pix_fmt yuv422p10 -r 60000/1001 -b:v 440M

      • 


    • -vcodec dnxhd -acodec pcm_s16le -pix_fmt yuv422p -r 24000/1001 -b:v 115M

      • 


    • -vcodec dnxhd -acodec pcm_s16le -pix_fmt yuv422p -r 25/1 -b:v 120M

      • 


    


    Any idea what's wrong ? How do I choose "correct" video format ?

    


    Is it possible that ffmpeg refuses to convert video when camera is rotated 90° ? i.e. the input resolution would be 1080x1920 ?

  • 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 ?
