• Raspberry Pi 4 live streaming with ffmpeg [closed]

  12 décembre 2019, par Berri

  So speedify created a blog post and youtube video about making an IRL streaming backpack using the Elgato Cam Link 4k, Raspberry Pi 4, and ffmpeg.

  They gave pretty detailed instructions, and included downloads to prebuilt scripts/commands to get it all running once put together.
  Blog post :
  https://speedify.com/blog/how-to/build-irl-streaming-backpack-complete-guide/

  ffmpeg command from post :

  ffmpeg_command = “/home/pi/bin/ffmpeg -nostdin -re -f v4l2 -s ‘1280×720’ -framerate 24 -i /dev/video0 -f alsa -ac 2 -i hw:CARD=Link,DEV=0 -vcodec libx264 -framerate 24 -rtbufsize 1500k -s 1280×720 -preset ultrafast -pix_fmt yuv420p -crf 17 -force_key_frames ‘expr:gte(t,n_forced*2)’ -minrate 850k -maxrate 1000k -b:v 1000k -bufsize 1000k -acodec libmp3lame -rtbufsize 1500k -b 96k -ar 44100 -f flv – | ffmpeg -f flv -i – -c copy -f flv -drop_pkts_on_overflow 1 -attempt_recovery 1 -recovery_wait_time 1 rtmp://live.twitch.tv/app/live_” + streamKey + “‘\n” 

  I replaced -i hw:card=link,dev=0 in that command with -i hw:2,0 because -i hw:card=link,dev=0 gave me "file does not exist" errors in the log. "streamkey" is filled with the appropriate key for my twitch.

  Github Resources + Instructions used :
  https://github.com/speedify/rpi-streaming-experiment

  I’m using all the exact same hardware as outlined in the post, and have gotten everything installed correctly as far as I can tell.
  But when I go to run the ffmpeg command, it seems like nothing actually gets sent over to twitch correctly.

  The log after trying to run it looks like this.
  If anybody has any insight as to what may be going wrong, it would be greatly appreciated.

• FFMPEG does not produce output a valid mp4 when called from Java

  13 décembre 2019, par VincBreaker

  I am merging an image with an audio file into a mp4-video using the ffmpeg-command :

  ffmpeg -y -r 30 -loop 1 -i <path></path>to/image.png> -i <path></path>to/audio.aac> -shortest -acodec copy -vcodec libx264 <path></path>to/output.mp4>

  To call this command from Java I’m using this code :

  ProcessBuilder builder = new ProcessBuilder("ffmpeg", "-y", "-r",
  
                      String.valueOf(generalConfig.getOutputFPS()), "-loop", "1", "-i", pictureFile,
  
                      "-i", transspoken.getVoiceFile(), "-shortest", "-acodec", "copy", "-vcodec", "libx264",
  
                      snippetOut);
  
  builder.redirectOutput(new File(getTMPName() + ".txt"));
  
  builder.redirectError(new File(getTMPName() + ".txt"));
  
  builder.redirectErrorStream(true);
  
  
  
  LogUtils.debug("FFMPEG-Render", String.join(" ", builder.command()));
  
  try {
  
      Process p = builder.start();
  
      p.waitFor();
  
  } catch (IOException | InterruptedException e) {
  
      e.printStackTrace();
  
  }

  This code runs without problem on my local machine running Ubuntu 18.04 Desktop and OpenJDK 11.0.4. However, when run on a Ubuntu 18.04 Server droplet, running the same OpenJDK-Version, the code results in a corrupted output. Strangely, there is absolutely no problem when I ssh into the server and call exactly the same command to generate the mp4 file. So I am in a the really strange situation where :

  1. The command works fine when called automatically on my local machine.
  2. The command works fine when called manually on the server.
  3. The command does not work when called automatically on the server.

  Output of the automated FFMPEG call on the server :

• FFMPEG images to video outputs junk

  15 décembre 2019, par GreatCorn

  I’m very new to using FFMPEG and I’m trying to make an image sequence into a video. However, none of my attempts were succesful. I first tried 825x480 .pngs which resulted in and then 512x512 .jpgs, pretty much the same result. I tried a few codes like ffmpeg -framerate 24 -i img%03d.png output.mp4, ffmpeg -r 1/5 -framerate 24 -i img%03d.png -c:v libx264 -vf -pix_fmt yuv420p output.mp4 and etc. I just don’t really understand what I’m supposed to do to prevent this.
