    I am new for video editing in android, I am finding a solution to edit a video in Android application, unfortunately I cannot get any examples for that, I need to place Image or text on video in a desired frame and also need to save it. Just like InShot android app , I tried to add simple text using ffmpeg but it tooks to much of time to save a video. Is there any alternative way to do that ?

  • stream usb webcam via http using vlc without transcoding using mjpeg signal from webcam

    10 novembre 2020, par Peter Nußreiner

    I wanna stream my (Microsoft live) USB webcam using vlc from a raspberry.
While it works perfectely fine with transcoding my raspberry does not have enough power.

    


    So I checked the output formats of my webcam using :

    


    ffmpeg -f v4l2 -list_formats all -i /dev/video0


    


    wich gives me the following output :

    


    [video4linux2,v4l2 @ 0x559d5aee36c0] Raw       :     yuyv422 :           YUYV 4:2:2 : 640x480 1280x720 960x544 800x448 640x360 424x240 352x288 320x240 800x600 176x144 160x120 1280x800
[video4linux2,v4l2 @ 0x559d5aee36c0] Compressed:       mjpeg :          Motion-JPEG : 640x480 1280x720 960x544 800x448 640x360 800x600 416x240 352x288 176x144 320x240 160x120
/dev/video0: Immediate exit requested


    


    when running my streaming command :

    


    cvlc v4l2:///dev/video0:chroma=h264:width=1280:height=720 --sout '#standard{access=http,mux=ts,dst=192.168.178.27:8080,name=stream,mime=video/ts}' -vvv


    


    I get the following error :

    


    mux_ts mux warning: rejecting stream with unsupported codec YUY2
main mux error: cannot add this stream
main decoder error: cannot create packetizer output (YUY2)


    


    along with many other lines of information.
As far as I can interpret the error, vlc wants to use the YUY2 RAW signal of my webcam.
Is there any way I can force vlc to use the mjpg output of my camera ?

    


    I've already tried to use 'chroma=mjpg' without success.
Transcoding is not an alternative as my raspi has by far not enough power.

    


    I've also read about using ffmpeg for streaming, maybe someone has an alternative solution since I'm very new to the whole topic of websites and stuff

    


    It will (or should) be used as a live webcam for a windsurfing spot.
Therefore I need a fluent video with at least 10fps to judge the situation. A delay of a minute or so is no problem.
The basic idea was to stream the video to a webserver and embed the image in a website. I've got good internet connection at the spot.

    


    But for now I want to try it locally on my pc.

    


  • How do I use ffmpeg on linux for my discord music bot ?

    7 mars 2023, par Dio

    I made a discord music bot a while back for me and my friends to use(it is minimalistic), but I recently switched from windows to Linux. I was using FFMPEG for my bot(the .exe file was in the same folder as the code).
I'll leave the Github link to my bot down here :

    


    https://github.com/Dorian1997/Discord-Bot

    


    Now my question is, do I have an alternative to FFMPEG on Linux ? Or how exactly should I install FFMPEG for it to work right ? I already installed it from the terminal, yet it doesn't seem to work as the bot cannot play anything.
Thank you for your time !
