  • Recording application output to video using FFmpeg (or similar)

    15 décembre 2011, par John

    We have a requirement to lets users record a video of our 3D application. I can already grab the individual rendered frames so this question is specifically about how to write frames into a video file.

    I don't think writing each frame as a separate file and post-processing is a workable option.

    I can look at options to record to a simple video file for later optimising/encoding, or writing directly to a sensibly encoded format.

    FFmpeg was suggested in another post but it looks a bit daunting to me. Is it the best option, if not what can be suggested ? We can work with LGPL but not full GPL.

    We're working on Windows (Win32 not MFC) in C++. Sample/pseudo code with your recommended library is very much appreciated... basically after how to do 3 functions :

    • startRecording() does whatever initialization is needed
    • recordFrame() takes pointer to frame data and encodes it, ideally with timing data
    • endRecording() finalizes the video file, shuts down video system, etc

  • Best approach to stream RTSP IP Cam feed to React app and node.js express server

    17 juillet 2024, par JuicyPhan

    I am trying to build a set-up whereby I stream multiple IP Cam RTSP Video feeds to multiple users.
It needs to have minimal latency.

    


    Server Hardware : Static IP Synology NAS
    
Front-End : React
    
Back-End : Node.js Express
    
STUN/TURN server : Coturn
    
Video Feed : Multiple IP Camera's RTSP feeds
    
Video Encoder : ffmpeg(?)
    
Video Decoder : ?
    
Video Format : ?
    
Streaming Protocol : WebRTC

    


    I have every individual component up however am struggling with the part whereby I encode the RTSP feed.

    


    What video format do I encode it to and how do I use WebRTC to stream to viewers on the front-end ?

    


  • Revision b295092b8f : Full range motion search for regular block sizes Add a full range motion search

    6 décembre 2013, par Jingning Han

    Changed Paths :
     Modify /vp9/common/vp9_rtcd_defs.sh


     Modify /vp9/encoder/vp9_mcomp.c


     Modify /vp9/encoder/vp9_onyx_if.c



    Full range motion search for regular block sizes

    Add a full range motion search for regular block sizes. This runs
    exhaustive search within the given reference area. This commit further
    optimizes the search process by combining 4 points test into one
    pipeline, which gives 30% speed-up as compared to run each individual
    point at a time.

    This full range search serves as a best possible motion search reference.
    When replacing the diamond search with full range search, the speed 0
    runtime of bus CIF at 2000 kbps goes from 153872ms to 623051ms. The
    compression performance compared to speed 0 setting gains 0.585% for
    derf set.
