  • ffmpeg : crop video into two grayscale sub-videos ; guarantee monotonical frames ; and get timestamps

    13 mars 2021, par lurix66

    The need

    


    Hello, I need to extract two regions of a .h264 video file via the crop filter into two files. The output videos need to be monochrome and extension .mp4. The encoding (or format ?) should guarantee that video frames are organized monotonically. Finally, I need to get the timestamps for both files (which I'd bet are the same timestamps that I would get from the input file, see below).

    


    In the end I will be happy to do everything in one command via an elegant one liner (via a complex filter I guess), but I start doing it in multiple steps to break it down in simpler problems.

    


    In this path I get into many difficulties and despite having searched in many places I don't seem to find solutions that work. Unfortunately I'm no expert of ffmpeg or video conversion, so the more I search, the more details I discover, the less I solve problems.

    


    Below you find some of my attempts to work with the following options :

    


      

    • -filter:v "crop=400:ih:260:0,format=gray" to do the crop and the monochrome conversion

      • 


    • -vf showinfo possibly combined with -vsync 0 or -copyts to get the timestamps via stderr redirection &> filename

      • 


    • -c:v mjpeg to force monotony of frames (are there other ways ?)

      • 


    


    1. cropping each region and obtaining monochrome videos

    


    $ ffmpeg -y -hide_banner -i inVideo.h264 -filter:v "crop=400:ih:260:0,format=gray" outL.mp4
$ ffmpeg -y -hide_banner -i inVideo.h264 -filter:v "crop=400:ih:1280:0,format=gray" outR.mp4


    


    The issue here is that in the output files the frames are not organized monotonically (I don't understand why ; how come would that make sense in any video format ? I can't say if that comes from the input file).

    


    EDIT. Maybe it is not frames, but packets, as returned by av .demux() method that are not monotonic (see below "instructions to reproduce...")

    


    I have got the advice to do a ffmpeg -i outL.mp4 outL.mjpeg after, but this produces two videos that look very pixellated (at least playing them with ffplay) despite being surprisingly 4x bigger than the input. Needless to say, I need both monotonic frames and lossless conversion.

    


    EDIT. I acknowledge the advice to specify -q:v 1 ; this fixes the pixellation effect but produces a file even bigger, 12x in size. Is it necessary ? (see below "instructions to reproduce...")

    


    2. getting the timestamps

    


    I found this piece of advice, but I don't want to generate hundreds of image files, so I tried the following :

    


    $ ffmpeg -y -hide_banner -i outL.mp4 -vf showinfo -vsync 0 &>tsL.txt
$ ffmpeg -y -hide_banner -i outR.mp4 -vf showinfo -vsync 0 &>tsR.txt


    


    The issue here is that I don't get any output because ffmpeg claims it needs an output file.

    


    The need to produce an output file, and the doubt that the timestamps could be lost in the previous conversions, leads me back to making a first attempt of a one liner, where I am testing also the -copyts option, and the forcing the encoding with -c:v mjpeg option as per the advice mentioned above (don't know if in the right position though)

    


    ffmpeg -y -hide_banner -i testTex2.h264 -copyts -filter:v "crop=400:ih:1280:0,format=gray" -vf showinfo -c:v mjpeg eyeL.mp4 &>tsL.txt


    


    This does not work because surprisingly the output .mp4 I get is the same as the input. If instead I put the -vf showinfo option just before the stderr redirection, I get no redirected output

    


    ffmpeg -y -hide_banner -i testTex2.h264 -copyts -filter:v "crop=400:ih:260:0,format=gray" -c:v mjpeg outR.mp4 -vf showinfo dummy.mp4 &>tsR.txt


    


    In this case I get the desired timestamps output (too much : I will need some solution to grab only the pts and pts_time data out of it) but I have to produce a big dummy file. The worst thing is anyway, that the mjpeg encoding produces a low resolution very pixellated video again

    


    I admit that the logic how to place the options and the output files on the command line is obscure to me. Possible combinations are many, and the more options I try the more complicated it gets, and I am not getting much closer to the solution.

    


    3. [EDIT] instructions how to reproduce this

    


      

    • get a .h264 video

      • 


    • turn it into .mp by ffmpeg command $ ffmpeg -i inVideo.h264 out.mp4

      • 


    • run the following python cell in a jupyter-notebook

      • 


    • see that the packets timestamps have diffs greater and less than zero

      • 


    


    %matplotlib inline
import av
import numpy as np
import matplotlib.pyplot as mpl

fname, ext="outL.direct", "mp4"

cont=av.open(f"{fname}.{ext}")
pk_pts=np.array([p.pts for p in cont.demux(video=0) if p.pts is not None])

cont=av.open(f"{fname}.{ext}")
fm_pts=np.array([f.pts for f in cont.decode(video=0) if f.pts is not None])

print(pk_pts.shape,fm_pts.shape)

mpl.subplot(211)
mpl.plot(np.diff(pk_pts))

mpl.subplot(212)
mpl.plot(np.diff(fm_pts))


    


      

    • finally create also the mjpeg encoded files in various ways, and check packets monotony with the same script (see also file size)

      • 


    


    $ ffmpeg -i inVideo.h264 out.mjpeg
$ ffmpeg -i inVideo.h264 -c:v mjpeg out.c_mjpeg.mp4
$ ffmpeg -i inVideo.h264 -c:v mjpeg -q:v 1 out.c_mjpeg_q1.mp4


    


    Finally, the question

    


    What is a working way / the right way to do it ?

    


    Any hints, even about single steps and how to rightly combine them will be appreciated. Also, I am not limited tio the command line, and I would be able to try some more programmatic solution in python (jupyter notebook) instead of the command line if someone points me in that direction.

    


  • Open VideoStream using OpenCV 4.5.1 works on Windows but fails on Docker python:3.9.2-slim-buster for specific IP cam

    18 mai 2021, par Qua285

    I have 2 ip cameras - one of Hikvision and another of Provision ISR. Both use Onvif and work on VLC.
I've written a simple python script to record images every 5 sec from their video stream.
On Windows 10, using VSCode they both work as expected. Once deployed to a Docker container, my script works as expected with the Hikvision but fails with the Provision ISR - it doesn't open the stream.

    


    Running python -c "import cv2; print(cv2.getBuildInformation())" on windows (venv 3.9.2) and on docker machine bring slightly different results but it's beyond my understanding to take something out of it...
Here is the Windows one :

  • Streaming Rtsp stream to website using FFmpeg and FFserver.

    23 août 2016, par Pallav Gupta

    I am working on a website for a client and one of the requirement is to embed the video from HikVision DVR DS7116. I have the RTSP url for the DVR. I want help with FFmpeg and FFserver. I already have written my ffserver config file.

    /etc/ffserver.config
    

    
Port 9500
    
# bind to all IPs aliased or not
    
BindAddress 0.0.0.0
    
# max number of simultaneous clients
    
MaxClients 1000
    
# max bandwidth per-client (kb/s)
    
MaxBandwidth 10000
    
# Suppress that if you want to launch ffserver as a daemon.
    
NoDaemon
    

    
<feed>
    
File /tmp/feed1.ffm
    
FileMaxSize 5M
    
</feed>
    

    
<stream>
    
Feed feed1.ffm
    
Format swf
    
VideoCodec flv
    
VideoFrameRate 15
    
VideoBufferSize 80000
    
VideoBitRate 100

VideoQMax 5
    
VideoSize 352x288
    
PreRoll 0
    
Noaudio
    
</stream>

    I next run my ffserver and ffmpeg command which is

    ffserver &amp; ffmpeg -re -i rtsp://admin:12345@192.168.1.3/MPEG-4/ch1/main/av_stream  http://192.168.1.105:9500/feed1.ffm

    The output which i receive is as follows

    I can see that with some errors, the stream starts.
    When i put the output url in my html code, there is no stream. I also tried playing the network stream in VLC and did not get anything. Can anyone please help me with that ? Any leads are also appreciated. Thank you.
