  29 avril 2021, par connor449

  When I run ffprobe <video></video>, I get the standard metadata as below :

  I want to get this information from python so I can parse this output and use some of it in my code. However, I can't get this to work.

  


  I have tried the following :

  


  data = subprocess.call(f'ffprobe {video}', shell=True)
data = subprocess.check_output(f'ffprobe {vid}', shell=True)
data = subprocess.Popen(f'ffprobe {vid}', shell=True)
data = subprocess. Popen(f'ffprobe {vid}', stdout=subprocess.PIPE ).communicate()[0]
data = run(f'ffprobe {vid}', capture_output=True).stdout


  


  If I include shell=True, then the proper information prints in the terminal but I get an empty string for data. For commands without shell=True I get file not found error and it breaks. What should I do ? I got all of these solutions from SO and they seem to work for others.

  


• Appium screen recording doesn't work on simulator

  31 août 2022, par Oks

  I'm running automation tests on simulator and trying to record screen but it crashes on line driver.start_recording_screen()
I'm using Python for testing and Flutter for client side.

  


  self.utils.driver.switch_to_native_context()

• ffmpeg convert RTMP stream to HLS ? RED5

  23 février 2017, par Lewis Day

  Before posting this question ; I followed this post ;
  https://ffmpeg.org/pipermail/ffmpeg-user/2013-November/018558.html I also tried to find solutions to the problem I’m having.

  ffmpeg -v verbose -i "rtmp://domain.com:5080/stream1" -c:v libx264 -c:a aac -ac 1 -strict -2 -crf 18 -profile:v baseline -maxrate 400k -bufsize 1835k -pix_fmt yuv420p -flags -global_header -hls_time 10 -hls_list_size 6 -hls_wrap 10 -start_number 1 '/home/domain/public_html/hts-streams/stream1.m3u8'

  Okay above is the Ffmpeg command I’m trying to execute to convert my RTMP stream into a .m3u8.

  However the command is failing and I’m being returned this ;

  I have changed my domain to domain.com

  RTMP_Connect1, handshake failed.

  The command then fails to convert the stream due to a failed handshake. What is causing this ?
