  • capture DV video and audio with ffmpeg and dshow

    18 novembre 2016, par andrixnet

    Trying to capture video and audio from a DV camera, using ffmpeg, I got into a problem.
    Before anything, I first tried to see (and hear) with ffplay.

    ffmpeg version :

    dummy: Immediate exit requested

    I can use VLC with "Capture device" as input, selecting "Microsoft DV Camera and VCR" as video device and leaving "Default" as audio device and I get both video and audio.

    With ffmpeg I get only video stream, no audio.

    C:\>ffplay -hide_banner -f dshow -i video="Microsoft DV Camera and VCR"
    Input #0, dshow, from 'video=Microsoft DV Camera and VCR':B f=0/0
     Duration: N/A, start: 0.010035, bitrate: N/A

      0.48 M-V:  0.013 fd=   0 aq=    0KB vq=    0KB sq=    0B f=0/0

    I don’t know how to tell ffmpeg the equivalent of "Default" audio device as VLC recognizes it.

    Device options show there are 2 pins for video device (DV device has both video and audio) but how can I tell ffmpeg such that it captures both video and audio ?

    C:\>ffplay -hide_banner -f dshow -list_options true -i video="Microsoft DV Camera and VCR"

  • Matomo maker InnoCraft named 2023 Hi-Tech Awards finalist

    20 avril 2023, par Erin — Press Releases

    WELLINGTON, N.Z., April 20, 2023 – InnoCraft, the makers of world-leading open-source web analytics platform Matomo, has been named an ASX Hi-Tech Emerging Company of the Year finalist in the 2023 Hi-Tech Awards. 



    Matomo founder Matthieu Aubry says, “At Matomo, we believe in empowering individuals and organizations to make informed decisions about their digital presence. By providing an open-source website analytics platform, we have created a more transparent and trustworthy digital ecosystem. We are proud to be recognised as a finalist for the Hi-Tech Awards, and we will continue to work towards a more open and ethical digital landscape, and grow the business in New Zealand and worldwide.”



    About Matomo

    Matomo, launched in 2007 as an open-source, privacy-friendly Google Analytics alternative, is trusted by over 1.5 million websites in 220 countries and has been translated in over 50 languages. Matomo tracks and analyses online visits and traffic to give users a deeper understanding of their website visitors to drive conversions and revenue ; while keeping businesses compliant with privacy laws worldwide, such as the EU’s General Data Protection Regulation (GDPR) and The California Consumer Privacy Act (CCPA).

    Aubry says Matomo is performing extremely well internationally as consumers and organizations look for privacy-focused analytics solutions, with several European countries already ruling the use of Google Analytics illegal due to data transfers to the US. In addition, Matomo’s user increase was recognized earlier this year with W3Tech’s award for the best web analytics software in its Web Technologies of the Year 2022 – with previous winners including Google Analytics and Facebook Pixel.



    A record number of companies entered the 2023 Hi-Tech Awards, with entries coming in from across the country and from all areas of the Hi-Tech sector. This depth is reflected in the line-up of finalists this year, according to David Downs, Chair of the Hi-Tech Trust, who says the standard of entries continue to grow every year.

”

    The hi-tech sector continues to flourish and it’s fantastic to see the success that so many of our companies enjoy on the international stage. This sector continues to prove its resilience and is at the forefront of our export economy in turbulent times,” says Downs.



    The Hi-Tech Awards Gala Dinner will take place on Friday, the 23rd of June, in Christchurch.

  • ffmpeg quits if one output stream fails - can this be prevented ? [duplicate]

    5 décembre 2017, par Caius Jard

    I’m responsible for maintaining a device that streams a live webcam feed to a remote relay server, and simultaneously writes a version of the stream to the local disk. It does this by a single instance of ffmpeg that has two outputs - one to the local disk, and one over rtsp to the streaming server

    I’m encountering a problem where by if the streaming server disconencts for any reason, ffmpeg quits. I’m not really bothered if the live stream is lost, but it’s a big problem that the local recording is lost also - it’s not a huge detriment to the particular business process if it cannot be watched live, but losing the locally stored copy is a disaster

    ffmpeg is started with a command line similar to :

    ffmpeg -thread_queue_size 4096 -async 1 -f v4l2
     -input_format mjpeg -framerate 30 -video_size 1280x720
     -i /dev/video0 -thread_queue_size 4096 -async 1 -f alsa
     -i plughw:CARD=Set,DEV=0 -r 30 -c:a aac -b:a 96k -c:v h264 -b:v 983040
     -profile:v baseline -preset veryfast -pix_fmt yuv420p
     -f tee -map 0:v -map 1:a
       [f=matroska]'/var/recordings/yyyy-mm-dd/backup.mkv'|
       [f=rtsp:rtsp_transport=tcp]rtsp://streamingserver.com:1234/session.sdp`

    Is there any way (command line switch etc) that ffmpeg can be made to carry on if an output stream is lost, rather than quitting ?
