FFMPEG does not add images to audio
20 février 2018, par GooglebotI want to create a slideshow with a background music by
ffmpeg, and use the commandffmpeg -f concat -safe 0 -i map.txt -i audio.flac -vsync vfr -pix_fmt yuv420p -strict -2 video.mp4and map.txt is like
file '1.jpg'
duration 15
file '2.jpg'
duration 60The result is a video with the audio and blank background. If I run the above command without audio as
ffmpeg -f concat -safe 0 -i map.txt -pix_fmt yuv420p -strict -2 video.mp4a perfect video of the images (the intended slideshow) is generated (but obviously without audio).
I reckon the problem is related to synchronising the audio and images.
This is the terminal output for the first command
ffmpeg -f concat -safe 0 -i map.txt -i audio.flac -vsync vfr -pix_fmt yuv420p -strict -2 video.mp4

Output Video frames are scrolling vertically when reading from rtmp source using python ffmpeg subprocess
24 février 2018, par nkottapalliThis is what I’m trying to do :
(1) Read rtmp stream with ffmpeg(python subprocess) and piping to rawvideo
(2) processing rawvideo pipe from (1) to opencv readable image using numpy
(3) process the image from (2) using opencv for whatever application
(4) Display or (Stream)to processed image from (3)
This is the code I’ve written :
FFMPEG_BIN = 'ffmpeg'
#SOURCE -> rtmp://yourdomain/rtmpappname/streamkey
SOURCE = 'YOUR RTMP INPUT STREAM HERE URL'
#DESTINATION -> rtmp://yourdomain/rtmpappname/streamkey
DESTINATION = 'YOUR RTMP PROCESSED OUTPUT STREAM URL'
#frame width and height of source stream
FRAME_WIDTH = 1280
FRAME_HEIGHT = 720
import subprocess as sp
#read from rtmp source and output to rawvideo pipe
cmd_video_only_in = [ FFMPEG_BIN, '-i', SOURCE, '-f', 'image2pipe', '-pix_fmt', 'bgr24', '-vcodec', 'rawvideo','-']
video_input_stream = sp.Popen(cmd_video_only_in, stdout=sp.PIPE, bufsize=FRAME_WIDTH*FRAME_HEIGHT*3, shell=False)
#(Optional) stream opencv processed frames to DESTINATION url with audio mapped from source, audio-video sync can be achieved by changing
#the float value 2.00 of -itsoffset to what suits you
#cmd_processed_stream_out = [FFMPEG_BIN,'-y','-thread_queue_size', '1024','-f', 'rawvideo', '-pix_fmt', 'bgr24', '-video_size', str(FRAME_WIDTH)+'X'+str(FRAME_HEIGHT),'-i','-','-itsoffset','2.00','-i', SOURCE,'-map','0:v:0','-map','1:a:0','-vcodec','libx264','-pix_fmt','yuv420p','-acodec','copy','-preset','ultrafast','-f','flv',DESTINATION]
#processed_output_stream = sp.Popen(cmd_processed_stream_out, stdin=sp.PIPE, shell=False)
import cv2
import numpy as np
import time
while (True):
raw_image = video_input_stream.stdout.read(FRAME_WIDTH*FRAME_HEIGHT*3)
image = np.fromstring(raw_image, dtype='uint8')
image = image.reshape((FRAME_HEIGHT,FRAME_WIDTH,3))
#Process the image
#any opencv based image processing can be done here eg. object detection, feature extraction, etc.,
#Display output
cv2.imshow('OUTPUT', image)
#(Optional)send the processed image frames (output) to DESITNATION rtmp url
#processed_output_stream.stdin.write(image.tostring())
video_input_stream.stdout.flush()
if cv2.waitKey(25) & 0xFF == ord('q'):
video_input_stream.terminate()
processed_output_stream.stdin.close()
processed_output_stream.terminate()
breakThe output frames which i’m trying to Display (using cv2.imshow) or Stream to rtmp destination are scrolling vertically from bottom to top. How do I solve this vertical scrolling issue ?
