Specifying minrate, maxrate and buffsize per representation

Thank you for the report.

Try the following code:

import datetime
import sys
import time

import ffmpeg_streaming
from ffmpeg_streaming import Formats


start_time = time.time()


def time_left(time_, total):
    if time_ != 0:
        diff_time = time.time() - start_time
        seconds_left = total * diff_time / time_ - diff_time
        time_left = str(datetime.timedelta(seconds=int(seconds_left))) + ' left'
    else:
        time_left = 'calculating...'

    return time_left


def monitor(ffmpeg, duration, time_, process):
    # You can update a field in your database or log it to a file
    # You can also create a socket connection and show a progress bar to users
    # logging.info(ffmpeg) or print(ffmpeg)

    # if "something happened":
    #     process.terminate()

    per = round(time_ / duration * 100)
    sys.stdout.write("\rTranscoding...(%s%%) %s [%s%s]" % (per, time_left(time_, duration), '#' * per, '-' * (100 - per)))
    sys.stdout.flush()

video = ffmpeg_streaming.input('/var/www/video.mp4')

hls = video.hls(Formats.h264())

_360p = Representation(Size(640, 360), Bitrate(276 * 1024, 128 * 1024), minrate="YOUR_MINRATE", maxrate="YOUR_MAXRATE", buffsize="YOUR_BUFFER_SIZE")
_480p = Representation(Size(854, 480), Bitrate(750 * 1024, 192 * 1024), minrate="YOUR_MINRATE", maxrate="YOUR_MAXRATE", buffsize="YOUR_BUFFER_SIZE")
_720p = Representation(Size(1280, 720), Bitrate(2048 * 1024, 320 * 1024), minrate="YOUR_MINRATE", maxrate="YOUR_MAXRATE", buffsize="YOUR_BUFFER_SIZE")

hls.representations(_360p, _480p, _720p)

hls.output('/var/media/hls.m3u8', monitor=monitor)
