  • nginx RTMP to HLS : FFMPG error when trying multiple bitrate output [closed]

    28 mai 2014, par user3685074

    I’m currently trying to convert my RTMP Livestream into a HLS with 3 quality-settings.

    I followed this guide

    I’ve compiled my own FFMPEG and it’s working if I just convert 1 file.
    It seems libx264 isn’t able to do multiple encodings at the same time ?

    I’m using these command :

            exec /usr/local/bin/ffmpeg -i rtmp://localhost/src/$name 
    
        -c:a libfdk_aac -b:a 32k   -c:v libx264 -b:v 128K -f flv rtmp://localhost/hls/$name_low 
    
        -c:a libfdk_aac -b:a 64k   -c:v libx264 -b:v 256K -f flv rtmp://localhost/hls/$name_mid 
    
        -c:a libfdk_aac -b:a 128k  -c:v libx264 -b:v 512K -f flv rtmp://localhost/hls/$name_hi  2>>/tmp/ffmpeg.log;

    this is the output :

  • FFmpeg/FFplay directshow and blackmagic

    21 janvier 2016, par max246

    I got a BlackMagic intensity pro 4k capturing card, which is working fine with the express tool, I can see the live feed and record, but after I tried different stuff from what I found online to make ffplay/ffmpeg working, I ended up to have just a black screen.

    I have checked if all the versions of my ffmpeg files were eanable-decklinnk, I have compiled the latest one with the latest version of the api, but still I get a black screen instead of the actually feed.

    By running the command line above, I can only see a black screen but not actually errors.

    I am running Windows 8.1 64bit.

  • Displaying the current frame of a video after skipping using drawtext/start_number not evaluation any variables

    25 mars 2023, par DJ Quardaboff

    I would like to display the current frame number on a video while playing it with ffplay. I have already seen this solution, but when I seek to any part of the video, the counter resets. There's a variable, start_number, which the ffplay documentation says is The starting frame number for the n/frame_num variable. The default value is "0". It seems that n is set to that when starting the video or seeking between I-frames. I thought setting this variable to %{floor(t*60)} would solve my problem, but after running this :

    



    ffplay -i "video.mp4" -vf drawtext="fontsize=30:box=1:boxcolor=white:fontcolor=black:fontfile=/Windows/Fonts/arial.ttf:start_number=floor(t*60):text=%{n}"


    



    I got the following console output :

    In fact, any variable in start_number's assignment invokes this error. I don't know if I have the correct syntax, but does this mean it doesn't evaluate expressions ? Or maybe it doesn't accept variables for some reason ?

    



    After that downer I tried just setting the text to %{t}, which played the video, but repeatedly gave this error and had no text in the top left corner :

    



    [Parsed_drawtext_0 @ 0000000003e54ea0] %{t} is not known 0B f=0/0


    



    So does the current time variable just not work in drawtext ?
    
Is there another way to write the current frame on the video or even on the console window ?

    



    Using Windows 10 Enterprise and the latest build of ffplay for windows at this time.
