• Problem updating drawtext with file using ffmpeg [duplicate]

  17 novembre 2020, par drmobbins

  I have a shell script that runs to combine a 24/7 AAC audio stream with a 720p HD picture/background and streams that output live to YouTube. This is for an internet radio station. The script works perfectly except for the drawtext option. The drawtext option references a file that is updated every 15 seconds (using Python and Cron) with the correct song metadata (from the radio automation suite) and is supposed to print the contents of the metadata file to the screen. This happens one time when the ffmpeg command is run in the script, but doesn't update after a song change.

  


  I would assume that since the metadata file is changing every 15 seconds on the server that it would update the song details in the output video that could be seen on YouTube...but it doesn't.

  


  #!/bin/bash

#Quality settings
VBR="1500k"
FPS="30"
QUAL="ultrafast"
AUDIO_ENCODER="aac"

#Youtube settings
YOUTUBE_URL=" rtmp://a.rtmp.youtube.com/live2"
YOUTUBE_KEY="xxxx-xxxx-xxxx-xxxx-xxxx"

#Sources
VIDEO_SOURCE="bg720p.jpg"
AUDIO_SOURCE="http://stream.url"

#Metadata settings
TRACK_METADATA=$(cat metadata.txt)

ffmpeg \
 -loop 1 \
 -re \
 -framerate $FPS \
 -i "$VIDEO_SOURCE" \
 -thread_queue_size 512 \
 -i "$AUDIO_SOURCE" \
 -vf "drawtext=fontfile=OpenSans-Light.ttf:text=$TRACK_METADATA:x=10:y=680:fontsize=20:fontcolor=white" \
 -c:v libx264 -tune stillimage -pix_fmt yuv420p -preset $QUAL -r $FPS -g $(($FPS *2)) -b:v $VBR \
 -c:a $AUDIO_ENCODER -threads 6 -ar 44100 -b:a 64k -bufsize 512k -pix_fmt yuv420p \
 -f flv $YOUTUBE_URL/$YOUTUBE_KEY


  


  What am I missing that will make the output continually check for file changes and use drawtext to display the contents. Thanks in advance !

  


• Continuous YouTube live stream via ffmpeg keeps failing after a while [closed]

  23 octobre 2024, par dooleyo

  I am trying to stream a simple MP4 file as a 24/7 YouTube radio station on repeat from a virtual machine using ffmpeg. It's only a 23 minute ( 1GB) file, and runs fine for hours or even days, then hangs up. I've tried on a small Digital Ocean droplet and detaching the ssh session with screen. I am using -c copy so I don't need to process or re-encode anything (even on the smallest droplet, the memory/cpu utilization is negligible, so I know that's not the issue). I have even tried some of ffmpeg's auto-restart options to no avail. Here is the command I'm currently running :

  


  ffmpeg -stream_loop -1 -re -i file.mp4 -c copy -drop_pkts_on_overflow 1 -attempt_recovery 1 -recover_any_error 1 -recovery_wait_time 1 -f flv "rtmp://x.rtmp.youtube.com/live2/{STREAM_KEY}"

  


  This works perfectly, for a time, then hangs up with :

  


  aost#0:1/copy @ 0x623b201c5fc0] Error submitting a packet to the muxer: Broken pipe

  There are not many articles I've found covering the broken pipe issue, but those that do seem to involve either A) streams that won't start, or B) streams where the broken pipe occurs the first time the input tries to loop (neither of which are my problem, since it streams and loops fine for quite a while).

  


  Thanks in advance !
