  • FFmpeg RTSP crash

    19 septembre 2016, par bot1131357

    I am trying to rtsp stream between two consoles on my computer.

    On console 1 I have :

    ffmpeg -rtbufsize 100M -re -f dshow -s 320x240 -i video="BisonCam, NB Pro" -r 10 -an -f rtsp -rtsp_transport tcp rtsp://127.0.0.1:8554/demo

    On console 2 I have :

    ffplay -rtsp_flags listen -i rtsp://127.0.0.1:8554/demo

    When I run execute both commands, my webcam LED lights up. But then immediately after ffmpeg crashes. Has anyone encountered the same thing ? I could really use some help here.

    This is my ffmpeg configuration on a Windows 10 machine :

Use -h to get full help or, even better, run 'man ffmpeg'

    Update

    I tried to stream from a video file, just to be sure that the issue is not related to the webcam.

    #Console 1
    
ffmpeg -i out.mp4 -f rtsp -rtsp_transport tcp rtsp://localhost:8888/live.sdp
    

    
#Console 2
    
ffplay -rtsp_flags listen rtsp://localhost:8888/live.sdp?tcp

    The output for both consoles are as follows :

    The same crash happened with ffmpeg.exe, and ffplay continued waiting for data. I tried the same commands on a Linux virtual machine, and it worked fine.

    Any ideas ?

    After building my own ffmpeg using the --enable-debug flag, I’m back at it again. Still getting the same error though. Any ideas ? At this point, it seems like there’s something wrong with my computer settings.

  • Should H.264 bit rate be multiples of 8 ?

    31 août 2016, par Dan Sharp

    I’m working on a video platform receiving H.264 video and building an HLS stream (transmuxing the H.264 to Mpeg2 TS segments via calls to ffmpeg).

    I wanted to set the bit rate to be about 2000 kbps, but I’m wondering : does it matter if it’s 2000 or 2048 ?

    In other words, do things calculate better if the bit rate is multiples of 8, like 512 or 2024 or 2048 ?

    I don’t know enough about how the bit rate is used, either on the sending side (camera) or on the processing side (ffmpeg).

    From tests... I can’t see any noticeable difference between 2000 and 2048, but maybe one is slightly better than another for the transmuxing and segmenting ?

    I welcome any thoughts/advice.

  • FFMPEG wmv conversion to flv

    25 novembre 2012, par Brandon Grossutti

    anyone using ffmpeg

    I have a fairly simple wmv exported by a user from movie maker with standard output and want to convert to .flv using

    C :>ffmpeg -i "E :\Jab Core 4 Recounters.wmv" -vcodec flv "C :\Net Projects\SVN\IntegratedAlgorithmics\src\MediaAdmin\MediaAdmin\bin\Debug\Movies\Jab Core 4 Recounters.flv" -ar 44100

    the output / error i receive is
