In the output it says : "No such file or directory".
I have been investing and didn't find any info about it.
Any idea on how to solve that problem?
run the server with administrative privileges.
make sure that running ffmpeg is included and running in the PATH environment variable.

i have a video encoded in 16bits. I cannot use opencv as it does not support 16bits video. So i tried ffmpeg-python. The video is around 1Go and each frame is 1M pixels. So, i would like to extract one frame at a time to process it, otherwise, it won't fit in memory. I mean it can, but i want to limit the amount of RAM used by my process.
I looked at examples here. I guess what is closer than what i want is the following, but instead of filling the numpy array with the whole video, i want to read one frame at a time. Or maybe it is possible to give ffmpeg a callback so that is returns a numpy array with all the frames already processed ?
out, _ = (
ffmpeg
.input('test.16b.raw.avi')
.output('pipe:', format='rawvideo', pix_fmt='gray16le')
.run(capture_stdout=True)
)
video = (
np
.frombuffer(out, np.uint16)
.reshape(-1, height, width, 2)
)

You can do this:
def extract_frame(input_vid, frame_num):
out, _ = (
ffmpeg
.input(input_vid)
.filter_('select', 'gte(n,{})'.format(frame_num))
.output('pipe:', format='rawvideo', pix_fmt='gray16le', vframes=1)

return np.frombuffer(out, np.uint16).reshape(-1, height, width, 2)
for i in range($totalFrameNumber):
frame = extract_frame($videoPath,i)
Change $totalFrameNumber and $videoPath.
I'm trying to remove a superfluous audio track from a movie file. Specifically, this movie on archive.org has the original audio as track 2, and what appears to be a slavic (Russian?) voiceover in track 1. I'd like to get rid of the latter.
I found this question that suggested I should do the following:
ffmpeg -i Benjamín\ dúfa.avi -map 0 -map -0:a:0 -c copy Benjamín\ dúfa\ \(aðeins\ íslenskt\ tal\).avi
But this doesn't work: after removing the first audio track, audio and video are not in sync in the resulting file anymore (when played in VLC). Now, I was able to overcome this problem by also reencoding the remaining audio track along the way, using
ffmpeg -i Benjamín\ dúfa.avi -map 0 -map -0:a:0 -c:v copy Benjamín\ dúfa\ \(aðeins\ íslenskt\ tal\).avi
But while this works, I'd like to understand why copying the audio track instead does not. I suppose it's a somewhat philosophical question --- consider it a matter of intellectual curiosity, combined with an aversion to needless lossy re-encoding.
So if anyone can explain this to me, I'd very grateful. Thanks!
EDIT: as per Gyan's request, here's ffmpeg's output for the first command:

I want to run a command that will add an image as a thumbnail to a video. The video will be shared by WhatsApp with a thumbnail showing up.
The problem is that after running the following command thumbnails don't show up in Whatsapp though it shows on Windows 10.
ffmpeg -i path/to/Video.mp4 -i path/to/Video.png -map 0 -map 1 -c copy -c:v:1 png -disposition:v:1 attached_pic -strict -2 path/to/out.mp4
And another problem is that the video with a thumbnail doesn't play on Android, iPhone, Windows, nor on Linux.

What am I doing wrong?
Note: It's okay if it works with python.
I noticed that when I transcode the videos to 30 fps, then I get a preview in WhatsApp.
Maybe this helps.
I am writing code to speed up video using FFMPEG with multiplier. 5X for five times faster video, 0.5X for twice slower video etc.
This code has worked previously in other use case, but it looks like there is something wrong with args array.
var spawn = require('child_process').spawn;
var cmd = 'node_modules\\ffmpeg-binaries\\bin\\ffmpeg.exe';
speedupFilename = tmpdir + vts + 'speedup.mp4';
var args = ['-i', filename, '-filter:v ', '"setpts=PTS/' + multiplier + '"', speedupFilename];
console.log(cmd + ' ' + args.join(' '));
var proc = spawn(cmd, args);
/* code that reads stdout and print it out to console */
This prints out in console:
node_modules\ffmpeg-binaries\bin\ffmpeg.exe -i C:\Users\User\AppData\Local\Temp\1533658543video.mp4 -filter:v "setpts=PTS/0.10" C:\Users\User\AppData\Local\Temp\1533658543speedup.mp4

[AVFilterGraph # 05c67dc0] No such filter: '"setpts'
Error opening filters!
I have setpts filter in my FFMPEG, I have looked into ffmpeg -filters.
If I run command (first line in output) in console, it works fine.
If I change -filter:v ', '"setpts=PTS/' + multiplier + '"' to -filter:v "setpts=PTS/' + multiplier + '"' in args array (remove ', ' to connect those two array items), then it just says At least one output file must be specified:

At least one output file must be specified
I finally figured out the solution.
In the array item '"pts=PTS/' + multiplier + '"' I had to remove quotation marks. They are useless, because argument is anyways isolated unlike in command line space is not enough.
This 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()
break
The 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?
