  • Using ffserver to stream older IP cam MJPEG to RTSP

    26 mai 2016, par tmar89

    I have an older Sony IP camera that has an MJPEG stream. I need to connect this to an NVR that only takes ONVIP or RTSP and I’m trying to use ffserver and ffmpeg to convert the MJPEG stream to RTSP but it’s not working. Any have some idea of what I may be doing wrong ? Saw an error in the attempted playback about an unsupported Protocol.
    Here is my ffserver config :

    Port 8090
    
RTSPPort 5544
    
BindAddress 0.0.0.0
    
RTSPBindAddress 0.0.0.0
    
MaxClients 100
    
MaxBandwidth 10000

File /tmp/feed27.ffm
    
FileMaxSize 5M

</feed>
    

    
<stream>
    
Format rtp
    
Feed feed27.ffm
    
NoAudio
    
VideoCodec mjpeg
    
VideoFrameRate 30
    
VideoSize 736x480
    
</stream>

    And here is the ffmpeg command I am using :

    [tm@tele ffserver-rtsp]# ffmpeg -f mjpeg -r 30 -s 736x480 -i http://[CAMIP]/image http://localhost:8090/feed27.ffm

  • FFmpeg Time Skipping after concat

    18 septembre 2017, par Manul Hüttinger

    i am trying to concatenate videos and in my resulting Videos i have the issue that at the concat edges my video is skipping/glitching.

    General Workflow

    in general my workflow looks like this

    1. Stream via ffmpeg
    2. capture stream and segment all 2 mins in to TS files
    3. concat TS file to MP4 video
    4. cut MP4 video at the desired Timestamps

    Detailed Look at Step 4

    as i am handling 2-hours+ videos i don’t want to re-encode the whole video. So i am looking for the closest I Frames to my In and Outpoint and cut 1 Frame before/after. As my result i get 3 Videos (front/middle/back). Now it is only needed to re-encode front and back and concat all three Videos.
    So far the theory

    General Observations

    As i look at my resulting video, i obeservated the following.
    frontpart duration is e.g. 3.2 secs. i skip framewise through the Video and get nice and clean timestamps ( 00:00:02.620, 00:00:02:660 )
    As soon as i get to my cutting edge the timestamps are skipping some frames and changing (00:00:03.200, 00:00:03.408 ,00:00:03.409). When i look only at the single frame images, their are no missing/dropped frames

    when i concat my TS files, the results contains a messed up frame rate e.g from constant 25 F/s to 25.0096 F/s

  • Windows video player cannot play cropped video from ffmpeg

    28 juillet 2019, par Chen Clarence

    I am trying to crop video with ffmpeg, I have encountered three problems.
    First, I used the following code to crop a 1080p video.

    ffmpeg -i 1080vid.avi -vf "crop=1920:1080:0:0" -c:v libx264 -crf 1 -c:a copy output.mp4

    However, in the compression rate argument, it only works if I set -crf to a positive value. If I set it to 0, then the output video cannot be played by my Windows 10 video player. However, since I am pursuing a lossless conversion, this is problematic. The output mp4 is smaller than 5% of the original size.

    The original goal was to cut a 1080*15360 video into 8 1080p videos. However, using the following code, I get unplayable output after playing with all the settings.

    ffmpeg -i sample.avi -vf "crop=1920:1080:0:0" -c:v libx264 -crf 1 -c:a copy output.mp4

    The input sample.avi is a lossless avi with bitrate larger than 1GB/s, and the output is a 70kb unplayable file. When opened, a pop up window displays :

    Choose something else to play. This item is in a format we don't support.
    
0xc00d36b4

    The following is the command line output.
