• FFmpeg stream giving me "Alsa" errors

  14 mars 2019, par Sherman B.

  Of late I have been trying different ways of telling my Raspberry Pi to send video to YouTube live stream. One of the things I wanted to be able to do is boot the Pi up, and it automatically starts the live stream on its own. The advantages to this are huge (won’t have to tote around keyboard/mouse to start the stream, or have to ssh into the Pi to start the stream).

  Now what I did to accomplish this was to make a Python program that pipes the stream from my encoder(FFmpeg) directly to the stream. My goal was to make the program work, and then, set it to run automatically. But every time I run the file in my terminal this is my result :

  Traceback (most recent call last):
  
    File "stream.py", line 22, in <module>
  
      stream.stdin.close() 
  
  NameError: name 'stream' is not defined
  
  [h264 @ 0x19ed450] Could not find codec parameters for stream 0 (Video: h264, none): unspecified size
  
  Consider increasing the value for the 'analyzeduration' and 'probesize' options
  
  pi@raspberrypi:~ $ Input #0, h264, from 'pipe:':
  
    Duration: N/A, bitrate: N/A
  
      Stream #0:0: Video: h264, none, 25 tbr, 1200k tbn, 50 tbc
  
  Unknown input format: 'alsa'
  
  </module>

  Now I think I can fix I can fix some of those errors, but the biggest thing that worries me there is : the fact that "alsa" is unknown. I installed "libsasound" which is supposed to make Alsa usable, but that clearly did not help.

  I am using Python 3.

  This is my syntax for this program :

  import subprocess 
  
  import picamera 
  
  import time 
  
  YOUTUBE="rtmp://a.rtmp.youtube.com/live2/" 
  
  KEY = ("MY PERSONAL ENCODER KEY") 
  
  stream_cmd = 'ffmpeg -f h264 -r 25 -i - -itsoffset 5.5 -fflags nobuffer -f alsa -ac 1 -i hw:1,0 -vcodec copy -acodec aac -ac 1 -ar 8000 -ab 32k -map 0:0 -map 1:0 -strict experimental -f flv ' + YOUTUBE + KEY 
  
  stream_pipe = subprocess.Popen(stream_cmd, shell=True, stdin=subprocess.PIPE) 
  
  camera = picamera.PiCamera(resolution=(640, 480), framerate=25) 
  
  try: 
  
    now = time.strftime("%Y-%m-%d-%H:%M:%S") 
  
    camera.framerate = 25 
  
    camera.vflip = True 
  
    camera.hflip = True 
  
    camera.start_recording(stream.stdin, format='h264', bitrate = 2000000) 
  
    while True: 
  
       camera.wait_recording(1) 
  
  except KeyboardInterrupt: 
  
       camera.stop_recording() 
  
  finally: 
  
    camera.close()
  
    stream.stdin.close() 
  
    stream.wait() 
  
    print("Camera safely shut down") 
  
    print("Good bye") 

  Now maybe I am missing something simple here, but I don’t know what. I have tried many ideas (e.g. replacing Alsa with some other input, naming the "stream" function.) I have no idea.

• FFMPEG is not recording the whole window

  25 mai 2021, par John

  I'm using FFMPEG to record a window as illustrated in the figure below. In all cases, the right hand side of the recorded window is cropped. The command I'm giving is

  



  ffmpeg -f gdigrab -i title="example.txt - Notepad++" output.mkv


  



  Any suggestion on how to fix this problem is much appreciated.

  



  

  



  Here are some additional info :

  



  

  • Running Windows 10

  


  • Using ffmpeg-20181215-011c911-win64-static, but I have the same issue using other versions of FFMPEG

  


  • Desktop resolution is 3200x1800 (dpi scaling issue ?)

  


  



  This is what the recorded area looks like in the example above

  



  

  



  Update 1 :

  



  Recording the whole desktop works fine, however, when recording a region using x and y offsets, the region captured is correct, but the region indicated is wrong. I illustrate this in the image below that shows a screen capture of the desktop during recording. The background image is a grid and the taskbar has been hidden.

  



  

  



  The size of the area to capture is specified to 1280x720, but the region indicated is 1600x900. Also, the x offset is specified to 400px, but the region indicted starts at 500px.

  



  The area recorded is correct ! The image below shows a screenshot of the recording during playback in vlc, note that the "misplaced" region indicator can be seen

  



  

  



  Update 2 :

  



  I noticed that the cursor, the mouse, is not correctly placed when capturing from the desktop, see recording below. Everything looks fine during recording, but at playback the cursor is misplaced.

  



  

  



  The command issued for the recording above was :

  



  ffmpeg -f gdigrab -framerate 30 -offset_x 1820 -offset_y 100 -video_size 1280x720 -i desktop output5.mkv
