  • Bad output from ffmpeg running on raw video from Wear OS device

    17 juin 2020, par lcj

    I am following these instructions regarding capturing and converting video from a Wear OS device, and I am running into problems. I get a video and I can tell it is my screen but it seems to be warped. This should be a green check with some white text.

    



    enter image description here

    



    There is a lot of noise when I run this :

    



    ffmpeg -f rawvideo -vcodec rawvideo -s 400x400 -pix_fmt rgb24 -r 10 -i video.raw -an -c:v libx264 -pix_fmt yuv420p video.mp4

  • Video watermarking with ffmpeg (output video size too big )

    22 janvier 2020, par kartik bansal

    i am running ffmpeg on video of size around 2 Mb and after watermarking them size of my video file is around 13-17 Mb. AM i doing something wrong. Please Help

    My code is

    ffmpeg -i "C:\flask\mobile_form\Videos\20191231140058_987654567.mp4" -i "C:\flask\mobile_form\resizeLogo.jpg" -filter_complex "[0:v][1:v]overlay=10:10,drawtext=text=Hello:fontsize=24:x=main_w-200:y=main_h-100,drawtext=text=World:fontsize=24:x=main_w-200:y=main_h-60" "C:\flask\mobile_form\waterMark\second.mp4"

    This is my full log, It is not giving any error but i want my output file to be smaller.

  • FFMPEG Streaming to twitch low bitrate

    17 juillet 2020, par El_Presidente

    I have a python script that will produce frames for a video stream. To stream it to twitch I decided to use ffmpeg (as it is the only option I found). However, the bitrate of my stream is very low (70 KB), although in ffmpeg options it's set to 3000K.

    


    # This script copies the video frame by frame
import cv2
import subprocess as sp
twitch_stream_key = 'MY_TWITCH_STREAM_KEY'
input_file = 'video.mp4'

cap = cv2.VideoCapture(input_file)
ret, frame = cap.read()
height, width, ch = frame.shape

ffmpeg = 'FFMPEG'
dimension = '{}x{}'.format(width, height)

fps = cap.get(cv2.CAP_PROP_FPS)
command = []
command.extend([
    'FFMPEG',
    '-loglevel', 'verbose',
    '-y',  # overwrite previous file/stream
    '-analyzeduration', '1',
    '-f', 'rawvideo',
    '-r', '%d' % fps,  # set a fixed frame rate
    '-vcodec', 'rawvideo',
    # size of one frame
    '-s', '%dx%d' % (width, height),
    '-pix_fmt', 'rgb24',  # The input are raw bytes
    '-thread_queue_size', '1024',
    '-i', '-',  # The input comes from a pipe
])       
command.extend([
    '-ar', '8000',
    '-ac', '1',
    '-f', 's16le',
    '-i', 'work.mp3',
])
command.extend([
    # VIDEO CODEC PARAMETERS
    '-vcodec', 'libx264',
    '-r', '%d' % fps,
    '-b:v', '3000k',
    '-s', '%dx%d' % (width, height),

    '-threads', '2',
    # STREAM TO TWITCH
    '-f', 'flv', 'rtmp://live-hel.twitch.tv/app/%s' %
          twitch_stream_key
])
proc = sp.Popen(command, stdin=sp.PIPE, stderr=sp.PIPE)

while True:
    ret, frame = cap.read()        
    if not ret:        
        break    
    proc.stdin.write(frame.tostring())

cap.release()
proc.stdin.close()
proc.stderr.close()
proc.wait()


    


    How can I increase the bitrate ? Maybe you can point me towards some different solution on how I can stream python frames to twitch or any other rtmp server.

    


    Here is the complete log, the audio is also broken, it's just noise :
