• FFMPEG Steam Stream stop after a few min

  24 novembre 2022, par Fabian Boulegue

  I try set a video stream to STREAM via FFMPEG so far everything works fine but after a few min it just seem to timeout (at last the stream stops but ffmpeg still send everything)

  



  Here is the ffmpeg string

  



  OUTRES="1920x1080"
GOP="60"
GOPMIN="15"
THREADS="4"
CBR="2500k"
QUALITY="ultrafast"
VIDEO="rescue.mp4"
STREAM_KEY="steam_62879128_f5xxxxxxxca5b1c"
SERVER="rtmp://ingest-01-fra1.broadcast.steamcontent.com/app/"

ffmpeg -stream_loop -1 -i $VIDEO -f flv \
-vcodec libx264 -g  $GOP -keyint_min $GOPMIN -b:v $CBR -minrate $CBR -maxrate $CBR -pix_fmt yuv420p \
-s $OUTRES -flvflags no_duration_filesize -preset $QUALITY -tune film -acodec aac -threads $THREADS -strict normal \
-bufsize $CBR "$SERVER$STREAM_KEY"


  



  this is the ffmpeg output

• Mix additional audio file with video(+audio) in ffmpeg

  21 mai 2019, par Serg

  I’m trying to mix additional audio file with video which has also audio within. But the problem is that I already have complex ffmpeg command and don’t know how to combine them together.

  This is my existing ffmpeg command which uses some offsets and replaces additional audio file with embedded one (audio inside video) and also overlays few gauges and watermark to the video.

  ffmpeg -y 
  
  -ss 00:00:01:213 -i videoFile.mp4 
  
  -ss 00:00:03:435 -i audioFile.wav 
  
  -i watermark.png 
  
  -framerate 6 -i gauge1_path/img-%04d.png 
  
  -framerate 1 -i gauge2_path/img-%04d.png 
  
  -framerate 2 -i gauge3_path/img-%04d.png 
  
  -framerate 2 -i gauge4_path/img-%04d.png 
  
  -framerate 2 -i gauge5_path/img-%04d.png 
  
  -framerate 2 -i gauge6_path/img-%04d.png 
  
  -filter_complex [0][2]overlay=(21):(H-h-21)[ovr0];
  
  [ovr0][3]overlay=(W-w-21):(H-h-21)[ovr1];
  
  [ovr1][4]overlay=(W-w-21):(H-h-333)[ovr2];
  
  [ovr2][5]overlay=(W-w-21):(H-h-418)[ovr3];
  
  [ovr3][6]overlay=(W-w-21):(H-h-503)[ovr4];
  
  [ovr4][7]overlay=(W-w-21):(H-h-588)[ovr5];
  
  [ovr5][8]overlay=(W-w-21):(H-h-673)
  
  -map 0:v -map 1:a -c:v libx264 -preset ultrafast -crf 23 -t 00:5:10:000 output.mp4

  Now I would like to use ffmpeg's amix in order to mix both audios instead of replacing them, if possible with ability to set volumes. But official documentation amix says nothing about volume.

  Separately both seems to work ok.

  ffmpeg -y -i video.mp4 -i audio.mp3 -filter_complex [0][1]amix=inputs=2[a] -map 0:v -map [a] -c:v copy output.mp4

  and

  ffmpeg -y -i video.mp4 -i audio.mp3 -i watermark.png -filter_complex [0][2]overlay=(21):(H-h-21)[ovr0] -map [ovr0]:v -map 1:a -c:v libx264 -preset ultrafast -crf 23 output.mp4

  but together

  ffmpeg -y -i video.mp4 -i audio.mp3 -i watermark.png -filter_complex [0][1]amix=inputs=2[a];[a][2]overlay=(21):(H-h-21)[ovr0] -map [ovr0]:v -map [a] -c:v libx264 -preset ultrafast -crf 23 output.mp4

  I’m getting an error :

  So my question : whether it’s possible to combine amix and overlay together and how and in which order they should be used ? Or should I look something different because amix unable to set volume levels ?

  Thanks in advance !

• Anomalie #4342 (Fermé) : Erreur 1071 de mysql : Specified key was too long ; max key length is 1000 ...

  26 mai 2019

  Bonjour,

  Après avoir configuré MariaDB pour être en UTF8MB4, je n’ai pas pu installer un plugin (comme il y a aussi un bug SVP, je vais faire un autre ticket spécifique).
  Pour être précis, un table du plugin n’a pas été créée et sql.log contient :
  

  2019-05-25 16:23:59 78.205.175.37 (pid 16091) :Pri:ERREUR : Erreur 1071 de mysql : Specified key was too long ; max key length is 1000 bytes

          date DATE NOT NULL,
          referer VARCHAR (255) ,
          PRIMARY KEY (referer)) ENGINE=MyISAM
  

  La documentation sur ce sujet est abondante.
  Ceci m’a semblé un bon résumé du problème : https://stackoverflow.com/questions/6172798/mysql-varchar255-utf8-is-too-long-for-key-but-max-length-is-1000-bytes
  Et la solution générale consiste à faire un index de seulement 191 : https://dev.mysql.com/doc/refman/5.7/en/charset-unicode-conversion.html :
  

  In an InnoDB table that uses COMPACT or REDUNDANT row format, these column and index definitions are legal :
  col1 VARCHAR(500) CHARACTER SET utf8, INDEX (col1(255))
  To use utf8mb4 instead, the index must be smaller :
  
  col1 VARCHAR(500) CHARACTER SET utf8mb4, INDEX (col1(191))
