  • ffmpeg take snapshot from webcam in windows 10

    12 juin 2019, par mrpatg

    Attempting to use ffmpeg to grab a snapshot from my USB webcam in windows 10.

    ffmpeg -f mjpeg "video=HD Pro Webcam C920" "C:\projects\webcam\" -vframes 1 -s 1920x1080 -ss 10 test.jpg

    Returns :

    Output #0, mjpeg, to 'video=HD Pro Webcam C920':
    Output file #0 does not contain any stream

    I think I might have something backwards here, but I’m not sure what.

  • Create H.264 stream from single PNG

    28 avril 2017, par Jim Rhodes

    I have an application that uses RTSP to get a video stream from an IP camera. The application extracts the H.264 data from the RTP packets and sends it to a remote process that decodes the stream (using ffmpeg) and displays it. If the video stream is interrupted for any reason, I would like to insert a static image into the stream being sent to the remote process.

    I have a PNG that is the same resolution as the camera. I thought I could use ffmpeg to encode the PNG to H.264 to get an IFrame that I could insert into the stream but I have not had any success. Using ffmpeg I created an MP4 with H.264 encoding from the PNG image and then extracted what I believed was the H.264 data from the MP4 but when I try to decode it ffmpeg returns an error.

    Anyone have any ideas on how I could accomplish this ?

  • Android MediaMetadataRetriever.METADATA_KEY_DATE gives only date of video on galaxy S7

    3 octobre 2016, par Zaid Bin Tariq

    I am writing a code to get video creation date and time from metadata, i am using following code to get creation date

    MediaMetadataRetriever retriever = new MediaMetadataRetriever();
    
retriever.setDataSource(path_to_video);
    
String date = retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DATE);

    it works perfect on all devices except Samsung Galaxy S7, it returns only date in "YYYY MM DD" format, no time stamp i need both date and timestamp.

    any help in this regard is much appreciated.
