• Lost video stream when streaming using FFmpeg and RTSP camera

  13 février 2019, par Vape

  on the Linux server, I have FFmpeg installed which streams video from Chinese low-cost IP camera to Twitch or Youtube server. After a few hours, the video is not visible but on the server side, the FFmpeg is still running and also the IP camera respond to the "ping" command.

  Here is the script I’m using :

  #
  
  # Camera IP
  
  #
  
  AQUARIUM_CAM_IP="192.168.123.102"
  
  
  
  
  
  #
  
  # Aquarium data file
  
  #
  
  AQUARIUM_DATA_FILE="/run/aquarium-cam/data.txt"
  
  
  
  
  
  #
  
  # FFmpeg parameters
  
  #
  
  FFMPEG_LOG_LEVEL=fatal
  
  
  
  # Bitrate (1000k = 1Mbit/s)  and  encoding speed (affects CPU)  and  number of CPU cores to use
  
  FFMPEG_VBR="1000k"
  
  FFMPEG_QUAL="ultrafast"
  
  FFMPEG_THREADS="1"
  
  
  
  # Streaming source
  
  FFMPEG_CAM_RTSP_SRC="rtsp://${AQUARIUM_CAM_IP}:554/user=admin&password=&channel=1&stream=0.sdp" # Camera source
  
  
  
  # Streaming destination
  
  FFMPEG_TWITCH_STREAM_URL_DST="rtmp://live-ber.twitch.tv/app"  # RTMP stream URL
  
  FFMPEG_TWITCH_KEY=""
  
  
  
  # Data overlay setup
  
  FFMPEG_TEXT_OVERLAY_FONT_PATH="OpenSans-Regular.ttf"
  
  FFMPEG_TEXT_OVERLAY_FONT_SIZE=25
  
  FFMPEG_TEXT_OVERLAY_OFFSET_X=5
  
  FFMPEG_TEXT_OVERLAY_OFFSET_Y=60
  
  FFMPEG_TEXT_OVERLAY_RELOAD=1
  
  FFMPEG_TEXT_OVERLAY_BOX="1"
  
  FFMPEG_TEXT_OVERLAY_BOX_BORDER_WIDTH="5"
  
  FFMPEG_TEXT_OVERLAY_BOX_COLOR="blue@0.5"

  the FFmpeg script :

   ffmpeg \
  
      -loglevel ${FFMPEG_LOG_LEVEL} -f lavfi -i anullsrc \
  
      -rtsp_transport tcp \
  
      -i "${FFMPEG_CAM_RTSP_SRC}" \
  
      -vcodec libx264 -pix_fmt yuv420p -preset ${FFMPEG_QUAL} -g 75 -b:v ${FFMPEG_VBR} \
  
      -vf "\
  
  drawtext=fontfile=${FFMPEG_TEXT_OVERLAY_FONT_PATH}:textfile=${AQUARIUM_DATA_FILE}:\
  
  x=${FFMPEG_TEXT_OVERLAY_OFFSET_X}:y=${FFMPEG_TEXT_OVERLAY_OFFSET_X}:\
  
  reload=${FFMPEG_TEXT_OVERLAY_RELOAD}: \
  
  fontcolor=white:fontsize=${FFMPEG_TEXT_OVERLAY_FONT_SIZE}:\
  
  box=${FFMPEG_TEXT_OVERLAY_BOX}:boxborderw=${FFMPEG_TEXT_OVERLAY_BOX_BORDER_WIDTH}:\
  
  boxcolor=${FFMPEG_TEXT_OVERLAY_BOX_COLOR}"\
  
      -threads ${FFMPEG_THREADS} -bufsize 512k \
  
      -f flv "${FFMPEG_TWITCH_STREAM_URL_DST}/${FFMPEG_TWITCH_KEY}"

  The other strange thing is that when the FFmpeg start and the stream begin the CPU utilization is about 30% in the case when there is no stream but the FFmpeg is still alive the CPU utilization is below 20% or less.

  Any Idea how to resolve this kind of problem ?
  Has FFmpeg some option to terminate if there is no "stream" or if it has lost a connection with a camera ?

• Android FFmpegKit-Full dependencies missing

  9 mai, par Adrián Primo

  I've tried to compile the app on Android and now it won't run as it can't find these files. I knew the *FFmpegKit *project was going to remove its binaries so I downloaded the package locally but I totally forgot about Android's specific files.

  


  Launching lib\main.dart on sdk gphone64 x86 64 in debug mode...
Running Gradle task 'assembleDebug'...

FAILURE: Build failed with an exception.

Execution failed for task ':app:checkDebugAarMetadata'.

  I've tried to download the dependencies manually from the repository, but the owner has removed the files.

  


  Does anybody have the required files for the ffmpegkit-full package ? I found in a forked repository with the https package installed locally, but I need the full package.

  


  Dependency in Maven Repository
