  • vaapi_h264 : Scale log2_max_pic_order_cnt_lsb with max_b_frames

    5 janvier 2017, par Mark Thompson
    vaapi_h264 : Scale log2_max_pic_order_cnt_lsb with max_b_frames

    Before this change, it was possible to overflow pic_order_cnt_lsb and
    
generate a stream with invalid POC numbering.  This makes sure that
    
the field is large enough that a single IDR B* P sequence uses fewer
    
than half the available POC lsb values.

  • What is the most efficient way to grab a specific frame from a video file by index ?

    4 février 2021, par Handelo

    So for some context - I'm creating a real-time data visualization tool in c# that needs to display video synced to other data. The playback needs to be stopped, resumed, scrubbed through and skipped through as smoothly as possible, similar to how it's done in video editing software, as well as have other data overlaid on top of it. To that end I do need the ability to get each frame by its index in a bitmap format. The video files are mostly MP4 encoded in x264, though support for other codecs is preferable.

    


    So far I've tried using both EMGU.CV and the Accord FFMPEG wrapper, but both solutions seem really slow at grabbing single frames - EMGU.CV's VideoCapture.SetCaptureProperty takes anywhere from half a second to 3 seconds to do so, and FFMPEG's VideoFileReader.ReadVideoFrame can take upwards of 10 (!) seconds.

    


    So what would be the most efficient solution here ? Is there another library I should try ?
