  • FFmpeg causing AttributeError : __enter__ on Win10

    11 juillet 2020, par Marci

    I have a python code which runs perfectly on win7, but i struggle for hours now making it work on my win10 laptop.

    


    Before manually installing FFmpeg i receive the error

    


        "assert _HAS_FFMPEG, "Cannot find installation of real FFmpeg (which comes with ffprobe)."
AssertionError: Cannot find installation of real FFmpeg (which comes with ffprobe)"


    


    so i downloaded, unzipped FFmpeg and set up the PATH. From now on i always receive the following error :

    


    with FFmpegReader(str(sourcepath)) as src:
AttributeError: __enter__


    


    I red that this error has something to do with the open() function. But the code works fine on my other computer ?!

    


    I would highly appreciate any hints. i am rather new to this field. Sorry if that is a senseless question.

    


  • Using Xuggler to detect Webcam with Java

    18 octobre 2012, par Oneiros

    I'm trying to use Xuggler library to handle webcam video stream in Java.

    My project contains these files :

    • Xuggler Jar (xuggle-xuggler-5.4.jar)
    • SLF4J Jars (required by Xuggler and downloadable here) :
      • jcl-over-slf4j-1.6.4.jar
      • jul-to-slf4j-1.6.4.jar
      • log4j-over-slf4j-1.6.4.jar
      • slf4j-api-1.6.4.jar
      • slf4j-ext-1.6.4.jar
      • slf4j-migrator-1.6.4.jar
      • slf4j-simple-1.6.4.jar
    • DisplayWebcamVideo.java as main class

    I run the main method using "vfwcap" and "0" as arguments.
    Application starts correctly, i can see myself from the webcam but it's just the first frame : the stream freezes and i see this output :

    5022 [Thread-3] ERROR org.ffmpeg - [vfwcap @ 000000000039A320] real-time buffer 75% full! frame dropped!

    5622 [Thread-3] ERROR org.ffmpeg - [vfwcap @ 000000000039A320] real-time buffer 85% full! frame dropped!

    6522 [Thread-3] ERROR org.ffmpeg - [vfwcap @ 000000000039A320] real-time buffer 95% full! frame dropped!

    6822 [Thread-3] ERROR org.ffmpeg - [vfwcap @ 000000000039A320] real-time buffer 101% full! frame dropped!

    6822 [Thread-3] ERROR org.ffmpeg - [vfwcap @ 000000000039A320] real-time buffer 101% full! frame dropped!

    What's the problem here ? :(

  • FFMPEG merge two .mp4 videos - resolution distorted

    9 juin 2016, par Misha Moryachok

    I am trying to merge two .mp4 videos, and in some cases the seconds video part is distorted in the output video. Providing an example below :
    https://www.youtube.com/watch?v=wWMNTBWJ37A

    The real video is : https://www.youtube.com/watch?v=ASio-j-Epi8

    As you can see, we added intro before the real content, however, the real content is stretched.
    In my opinion it happens because first video is 1280x720 and the second is 460x720.

    Providing commands for merging videos :

    *1st step (convert the videos from .mp4 to .ts)

     ffmpeg -i videoPathMP4 -c copy -bsf:v h264_mp4toannexb -f mpegts videoPathTS

    *2nd step (merge videos)

    ffmpeg -i "concat:$video1 | $video2" -c copy -bsf:a aac_adtstoasc $meagePathMP4

    Video output is like you saw in provided videolink on youtube.
    I also tried to change the first video resolution to be like the second video :

    ffmpeg -i inputVideo.mp4 -s 460x720 outputVideo.mp4

    However it doesn’t helped.
    Is anyone know how to solve this ?
    Thanks
