    $ ffmpeg -i sample.mp4 -v 0 -vcodec mpeg4 -f mpegts udp://127.0.0.1:23000


    


    I have not been able to stream the file on VLC.

    


  • Regarding making a AVI file from G.711 PCM audio and H264 video

    23 septembre 2019, par Nidheesh V

    I have a G711 alaw and G711 ulaw audio pipes, and a h.264 video pipe.

    I want to create a .avi file which is made using the G711 audio and video using ffmpeg binary.

    i have tried using the below commands to generate ,but no luck

    ffmpeg -f h264 -i  /tmp/stream-0.h264 -vcodec  copy  -f pcm_alaw -i /tmp/audio-0.g711   -acodec copy  /tmp/sdcard/re_main.avi.

    When i run this command, the ffmpeg just hangs with the below print

    Seems stream 0 codec frame rate differs from container frame rate: 50.00 (50/1) -> 25.00 (50/2)
    
Input #0, h264, from '/tmp/stream-0.h264':
    
  Duration: N/A, bitrate: N/A
    
    Stream #0.0: Video: h264, yuv420p, 1920x1080, 25 fps, 25 tbr, 1200k tbn, 50 tbc

    How can we make a AVI file ?

  • making screenshots from a wmv video with ffmpeg in linux [closed]

    28 avril 2013, par John

    when I try to make screenshots from a wmv video it shows-
    Error while decoding stream #0.1 - frame= 0 fps= 0 q=0.0 Lsize= -0kB time=10000000000.00 bitrate= -0.0kbits/s video:0kB audio:0kB global headers:0kB muxing overhead -inf%

    the command I am using for taking the video screenshots is - ffmpeg -i name.wmv -r 1/20 %03d.jpg

    I am using ffmpeg in linux, the video in question was originally encoded with Windows Media Video 9 and I can screenshot the video fine in windows but I cannot get it to work in linux.

    mediainfo shows the following - Video Format : VC-1 - Codec : WVC1, Microsoft

    ffmpeg -codecs|grep wmv shows that the wmv codec is already installed.

    avi, mpeg, mpg, mov and mp4 videos are all working fine, its only wmv file types which gives me this error so what can I do now ?

    thanks
