  • how to synchronize multiple rtsp streams using ffmpeg (or another tool ?)

    23 janvier 2015, par user1913115

    i have several RTP/RTSP live streams that i need to capture to individual mp4 files. this is what i’m doing :

    ffmpeg -i rtsp://source1/video \
    
       -i rtsp://source2/video \
    
       -i rtsp://source3/video \
    
       -map 0 -codec copy out1.mp4 
    
       -map 1 -codec copy out2.mp4 
    
       -map 2 -codec copy out3.mp4

    which works fine except when packets/frames are dropped, i end up with 3 files of different lengths. e.g. after an hour of capture, i may have this :

    out1.mp4 - 59m58s

    out2.mp4 - 59m30s

    out3.mp4 - 56m41s

    when looking at ffmpeg output i see this periodically :

    [NULL @ 0x7ff8c3843600] RTP: missed 8 packets
    
[NULL @ 0x7ff8c3843600] RTP: missed 570 packets
    
[NULL @ 0x7ff8c3843600] SEI type 81 size 672 truncated at 264

    is there a way to synchronize these videos ? i.e. if a packet is dropped on source3 to drop same packets on source1 and source2 ? or repeat last received frame as many times as required on source3 to have videos in sync with each other ?

  • checkasm : Add a "run-checkasm" make target

    14 février 2024, par Martin Storsjö
    checkasm : Add a "run-checkasm" make target

    Contrary to the existing "fate-checkasm", this always prints the
    
tool output, and runs all tests at once instead of splitting it up
    
per target group. This is more useful when the user expects to
    
look directly at the tool output, instead of being part of a full
    
fate run.
    

    (On failure with the regular "make fate-checkasm" targets, none of
    
the tool output is printed, but stored in files. If run with reporting
    
set up to the FATE website, the individual failures are uploaded there,
    
but if it is run in some sort of other CI setup, the intermediate files
    
might not be available afterwards for inspection.)

  • Create MPEG-DASH Initialization segment

    5 janvier 2016, par Mahout

    I am looking to convert between HLS and MPEG Dash. I do not access to the original fully concatenated video file, only the individual HLS segments.

    In doing this transformation to MPEG Dash I need to supply an initialziation segment for the Dash manifest .mpd file.

    My questions are :

    1. What is the structure of a Dash video initialization segment ?
    2. How can I generate/create one without the need for the original full file ?

    Perhaps a solution would involve getting MP4Box to convert the ’.ts’ HLS segments to Dash ’.m4s’ segments which are self initializing, but I am unsure how to go about this this ?

    Any ideas are much appreciated.

    Many thanks.

    UPDATE :
    Snippet to stream using original hls segments. Video plays all the way through but is just black.
