• Difference between MPEG-TS and RTP for H.264 (.mp4) video streaming ?

  6 avril 2022, par Candy

  So I am trying to stream a H.264 (.mp4) video over ETHERNET using the ffmpeg tool. I have read a little about transport of H.264 video over ethernet and have learnt that there are two methods ; mpeg-ts and RTP (both over UDP). I have been able to stream the .mp4 video through both methods in ffmpeg (over localhost) and haven't noticed any difference in quality or latency as such. What is the difference in concept and efficiency between the two protocols for transportation of video ? Or am I mixing two different concepts ? Any help is appreciated !

  


• problem in making HLS using ffmpeg problem

  24 juin 2023, par AMZ

  I have a function do run in background and create m3u8 for some videos : (I is running in background and updating some fields in django).

  


  def convert_to_hls(episode):
    # Set the output directory for HLS files
output_dir = os.path.join(settings.MEDIA_ROOT, 'hls')
os.makedirs(output_dir, exist_ok=True)

# Set the input video file path
input_file_path = episode.videoFile.path

# Set the output filename and path for the HLS playlist
# filename = os.path.splitext(os.path.basename(input_file_path))[0]
characters = string.ascii_letters + string.digits
filename = ''.join(random.choice(characters) for _ in range(45))
playlist_path = os.path.join(output_dir, f'{filename}.m3u8')

# Set the output path for the HLS segments
segments_path = os.path.join(output_dir, f'{filename}_%05d.ts')

# Construct the ffmpeg command for HLS conversion
command = [
    'ffmpeg',
    '-i', input_file_path,
    '-c:v', 'libx264',
    '-crf', '23',
    '-preset', 'medium',
    '-c:a', 'aac',
    '-b:a', '128k',
    '-f', 'hls',
    '-hls_time', '10',
    '-hls_list_size', '0',
    '-hls_segment_filename', segments_path,
    playlist_path
]
# Execute the ffmpeg command
subprocess.run(command, check=True)

episode.hls_created = True
episode.hls_url = playlist_path.replace("/home/debian/project","")
episode.save()

return True


  


  this code works well for most of my videos but for some .mp4 files gets :

  Also it does not work for .MOV files.

  


• FFmpeg doesn't play audio, yet no error shown

  4 août 2023, par Kristupas

  So i'm learning Python and don't know much about FFmpeg. I am following a tutorial, which explains everything very clearly. Everything is working, with one exception. Whenever I try to get it to play a sound, it won't.. Here's what it is saying :

  


  INFO     discord.player ffmpeg process 2540 successfully terminated with return code of 1.

  


  And here's my code (forgive me for all of the childish things in there, i'm just trying out different features) :

  I tried installing different versions of ffmpeg, still nothing. I tried to run the code outside of my venv, but still nothing (i doubt that it's the problem). I changed the path to it to different folders, still nothing.
The only time it DID work is when i entered a full path, but then when you want to play something, you wouldn't want to say " !play D:_Python\DiscordBot\Bluetooth.wav". From what i've seen, it's possible to play it by just saying " !play Bluetooth.wav".

  


  So long story short : I want to make it so that the path i have to specify is just the file name. And when I do, it doesn't play the sound.
(sorry if this is a dupe question, i just couldn't find anything understandable for my amateur brain)
