  • For converting video to frames, should I do client or server side processing ?

    23 mars 2024, par Tomas Marson

    Here is the thing, I have a Nodejs API that serves one video at a time when client request it.

    


    The client (made in react) receives the video, which has no more than 15 seconds, watch it and decide if he wants to approve or deny it.
If he approves the video, it must be displayed in a sort of frames carousel, with one frame per second, so there is no more than 15 images/frames.

    


    So the question is, should I do the conversion video-to-frames on client once he approves the video or should I do it on server-side and then request each frame (or streaming all frames with one request if possible) ?

    


    Now, I'm doing the conversion on server with ffmpeg, but it seems tricky to send all the frames when the client already have them inside the video.

    


  • avformat/matroskaenc : Don't use stream side-data size

    avformat/matroskaenc : Don't use stream side-data size

    av_stream_get_side_data() tells the caller whether a stream has side
    
data of a specific type ; if present it can also tell the caller the size
    
of the side data via an optional argument. The Matroska muxer always
    
used this optional argument, although it doesn't really need the size,
    
as the relevant side-data are not buffers, but structures. So change
    
this.
    

    Furthermore, relying on the size also made the code susceptible to
    
a quirk of av_stream_get_side_data() : It only sets the size argument if
    
it found side data of the desired type. mkv_write_video_color() checks
    
for side-data twice with the same variable for the size without resetting
    
the size in between ; if the second type of side-data isn't present, the
    
size will still be what it was after the first call. This was not
    
dangerous in practice, as the check for the existence of the second
    
side-data compared the size with the expected size, so it would only be
    
problematic if lots of elements were to be added to AVContentLightMetadata.
