  • FFmpeg : Cut from live stream RTSP

    10 septembre 2020, par Jax2171

    I cannot solve my problem and I have not found any solution.

    


    I capture an rtsp stream from an ip camera via the command :

    


    ffmpeg -stimeout 2000000 -abort_on empty_output -rtsp_transport tcp -i rtsp://admin:admin@192.168.1.15/av0_0 -c:v copy -c:a aac -f mpegts -y rec.ts


    


    The native video codec is h264 while the audio one is pcm. I capture the video stream without compression and compress the audio in aac to make it compatible with the ts container.

    


    I need to extract portions of video of X duration through during the capture. The command I use is :

    


    ffmpeg -ss X-i rec.ts -c:v copy -c:a copy -t Y -f mp4 -stimeout 60 -y cut.mp4


    


    Everything seems to work fine with no errors. However, the cut file has a slightly longer audio length than the video length. Sometimes the difference can be up to 1 second.

    


    My problem is that I have to chain all the cuts I make, and this difference in duration causes a very annoying lag between one video and another.

    


    It also happens that there is asynchronousness between audio and video in the cuts. The higher the -ss value, the more the audio anticipates the video.

    


    I state that I am not a professional but from what I have read it could be a problem of different PTS between audio and video, but I'm not sure. However, I am sure that the problem arises from the capture of the stream perhaps not in accordance with my needs.

    


    How can I solve ?

    


  • Unable to use Makefile on ffmpegthumbnailer setup files with Cygwin for Windows 10

    21 août 2018, par Cole Phiper

    I am currently trying to build the exe/binary files to support ffmpegthumbnailer on Windows 10. I read multiple posts on getting it to work, but none seem to satisfy my needs. I currently have ffmpegthumbnailer-2.2.0 stored at C :\ffmpegthumbnailer-2.2.0 I see a folder named CMakeFiles, dist, kffmpegthumbnailer, libffmpegthumbnailer, man, test and thunar files. When I run make in the directory, I receive

    User@User-WIN10 /cygdrive/c/ffmpegthumbnailer-2.2.0/man
    
$ make
    
make: *** No targets specified and no makefile found.  Stop.

    How do I build/make the exec files, so that I can use the PATH variable to find ffmpegthumbnailer ?

    UPDATE 1 :
    I tried the automake command, but I received the message below

    $ automake
    
/cygdrive/c/RubyDevKit/mingw/bin/automake: /cygdrive/c/RubyDevKit/mingw/bin/automake-1.11: /bin/perl: bad interpreter: No such file or directory
    
/cygdrive/c/RubyDevKit/mingw/bin/automake: line 156: /cygdrive/c/RubyDevKit/mingw/bin/automake-1.11: No error

    UPDATE 2 :

    I ran cmake and received the message below.

    I am working with ffmpeg. I want to give effects in video like grayscale, Sepia, Blur in video. Also I want to add text in those videos. How can I make this with ffmpeg in node js. I have worked with fluent-ffmpeg & ffmpeg node module.
