  • Raspberry Pi Camera Module - Stream to LAN

    20 août 2015, par user3096434

    have a little problem with the setup of my RasPi camera infrastructure. Basically I have a RPi 2 which shall act as a MontionEye server from now on and 2 Pi B+ with camera modules.

    Previously, when I had only one camera in my network, I used the following command to stream the output from RPi B+ camera module to Youtube in full HD. So far, this command works flawless :

    raspivid -n -vf -hf -t 0 -w 1920 -h 1080 -fps 30 -b 3750000 -g 50 -o - | b ffmpeg -ar 8000 -ac 2 -acodec pcm_s16le -f s16le -ac 2 -i /dev/zero -f h264 -i - -vcodec copy -acodec aac -ab 64k -g 50 -strict experimental -f flv $RTMP_URL/$STREAM_KEY

    Now I have a 2nd RPi with a camera module and figured it might be the time for a change towards motioneye, as I then can view both/all camera’s in my network within the same software. I have motioneye installed on my RPi 2 and the software is running correctly.

    I have a little problem when it comes to access the data stream from the RPi B+ camera on my local network.

    Basically I cannot seem to figure out how to change the ffmpeg portion of the above mentioned command, in a way so it will stream the data to localhost (Or the RPi2 IP where motioneye runs - which one to use ?) instead of Youtube or any other videohoster.

    I wonder, if changing the following part is a correct assumption :

    Instead of using variables to define Youtube URL and key

    -f flv $RTMP_URL/$STREAM_KEY

    And change this to

    -f flv 10.1.1.11:8080

    Will I then be able to add this RPi B+ video stream to my RPi 2 motioneye server, by using motioneye ’add network camera’ function ?

    From my understanding I should be able to enter the following details into motioneye ’add network camera’wizard :

    Camera type: network camera
    
RTSP-URL: 10.1.1.11:8080
    
User: Pi
    
Pass: [my pwd]
    
Camera: [my ffmpeg stream shall show here]

    Thanks in advance !

    Uhm, and then... How do I forwarded the video stream from a given camera connected to motioneye ? Like from motioneye to youtube (or similar), without re-encoding the stream ?

    Like the command shown above streams directly to youtube. But I want to have it in a way, that video is streamed to local network/motioneye server, and from there I can decide which camera’s stream and when I want to send the videostream to youtube ?

    How would a RPi professional realize this ?

    The command above explained : Takes full HD video with 30 fps from Pi camera module and hardware encodes it on GPU with 3.75mbit/s. Then I streamcopy the video (no re-encoding) and add some audio, so that the stream complies with youtube rules (yes, no live stream without audio). Audio is taken from virtual SB16 /dev/zero at low sampling rate then encoded to 32k AAC and sent to youtube. Works fine xD.

    Just when I have like 3 or more of these RPi cams the youtube stream approach ain’t feasible anymore, as my DSL upstream is limited (10 mbit/s=. Thus I need motioneye server and some magic, so I can watch f.e. all 3 camera’s videostream and then motioneye server can select and streamcopy the video from the Pi’s cam I choose and send it to youtube, as the original command did.

    Any help, tips, links to similar projects highly appreciated.

    Again, many thanks in advance, and even more thanks just cause you read until here.

  • ffmpeg : How to speed up (and keep only) a specified portion of an input video

    17 avril 2020, par shrimpwidget

    In my input video is a 48 second range that I wish to speed up. I wish to save only that sped up portion to a new video.

    



    Solution :

    



    ffmpeg -y -ss 00:00:03 -t 00:00:48 -i input.mp4 -an -crf 20 -pix_fmt yuv420p -vf "scale=1080:-1, setpts=PTS/10.0" "output.mp4"


    


  • | NGINX | FFMPEG not creating DASH manifests or chunks in the designated DIR |

    7 avril 2020, par Mathew Knight

    Hopefully someone can help here, I have a setup that takes two input RTMP streams from two separate machines into my server. From here I am trying to serve some MPEG DASH manifests and chunks to an experimental spatial audio/360 web (.js) player.

    



    My issue is that while i can see the FFMPEG processes running and creating the Chunks the files themselves are not appearing in the specified folder and so the media player will not read the content.

    



    Is there something obvious that i am not doing that is preventing these files being written ?

    



    Any help with this would be amazing !!!

Codec AVOption tile-columns (Number of tile columns to use, log2) specified for output file #0 (http://localhost:1935/dash/video.mpd) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
Codec AVOption frame-parallel (Enable frame parallel decodability features) specified for output file #0 (http://localhost:1935/dash/video.mpd) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
