  • FFmpeg drawtext and live coordinates with sendcmd/zmq

    9 mai 2019, par DavidK

    I’d like to use a marker on a live video source which has external live data to set x,y coordinates. sendcmd can read the text file but it won’t update it, so later updates are not executed. Is it possible only with zmq ? And if so, can I use zmq as a single filter (with drawtext), not with filter complex ?

    I have a python that exports live coordinates in the appropriate format to a cmd.txt file. I use unix time for the coordinates and I also copy the input timestamps from the live loopback device so they have almost the same time. There’s a small delay so I have compensated the exported timestamps with +1.5s. This means the marker is moving for this extra period (while timestamps in cmd.txt are a bit ahead of the live source), but it won’t update any more. I assume that FFmpeg reads this cmd.txt and won’t update it any more but my python is writing it continuously.

    Example line of the cmd.txt :

    1557402120.3119707 drawtext reinit 'x=752:y=480';

    This is the actual ffmpeg pipe :

    ffmpeg -fflags nobuffer -vaapi_device /dev/dri/renderD128 -f v4l2 -i /dev/video0 -vf "sendcmd=f=cmd.txt,drawtext=fontfile=font.ttf:fontsize=30:fontcolor=white:r=25:text='o',format=nv12,hwupload" -copyts -c:v h264_vaapi -qp 24 -y 0.mp4

    Source is a loopback device with unix time as input timestamp.

  • How to download live stream that consists out of separate .ts and .aac segments ?

    10 juin 2020, par Jan

    There is a m3u8 file with only the containing links to video segments and a different one with only the audio segments. Because it is a live streaming I have to start downloading both video and audio streams at the same time.
When just writing "ffmpeg input output" for video and the same command for audio in the following line, the program is trying to download the video file "until the end" before starting the audio stream — which does naturally not work since the live stream is indefinite.

    


  • hls live streaming using ffmpeg in iOS

    25 mars 2015, par chetan

    I am new to ffmpeg and I am trying to create live streaming app (HLS) and I want Live broadcasting rather than VOD.

    I am able to use ffmpeg through terminal and create .ts files from m4v but I am not getting how to achieve the same thing in iPhone.

    My approach is to create .ts files at iPhone end and then send it to server.

    I am not sure if this approach is correct, If this correct how I can create .ts files then otherwise what’s the right approach ?
