  • VLC command line : RTSP to mp4 file (video + audio)

    8 février 2016, par Dmitriy Gerashenko

    Win 7 x64.

    When I watch this link in VLC player all is fine :

    rtsp ://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov

    When I try to capture link to file and to display :

    • There is video without sound on display.
    • Created file is not playable.

    Command :

    vlc.exe -vvv "rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov" --sout="#transcode{venc=ffmpeg,vcodec=mp4v,vfilter=canvas{width=800,height=600},aenc=ffmpeg{strict=-2},acodec=mp4a}:duplicate{dst=display,dst=standard{access=file,mux=mp4,dst=video.mp4}"

    There are some errors in log, for example : MPEG4GenericRTPSource Warning: Unknown or unsupported "mode": AAC-hbr. Is it cause of my problems ? How to solve my issue ?

    Complete log (from VLCJ) :

      process.kill()  

    i wrote the code . but in this process the output file is getting corrupted.

    Dim pProcess() As Process = Process.GetProcesses
    
  For Each p As Process In pProcess
    
   If p.ProcessName = "ffmpeg" Then
    
    p.WaitForExit(1000)
    
    p.Kill()      
    
    p.Close()
    
  End If
    
Next

    is there any other method to terminate the process without file being corrupt

    thanks

  • ffmpeg video conversion from webm to mp4 is adding lag to the video

    21 janvier 2016, par Hemant Kumar

    Hi I am trying to convert video from .webm extension to .mp4 extension and it is adding lags to the video, also not showing me the full video.

    I am using following video conversion command.

    "ffmpeg -i {$input} -strict -2 -vcodec libx264 -preset slow -vb 500k -maxrate 500k -bufsize 1000k -vf 'scale=-1:480 ".fix_video_orientation($input)."' -threads 0 -ab 64k -s {$resolution}  -movflags faststart -metadata:s:v:0 rotate=0 {$output}";

    "fix_video_orientation" function is given below. It rotate the resulting video if video while recording is rotated to certain angle.

    function fix_video_orientation($input){
    

    
$return= ", transpose=1 ";
    

    
$dd= exec("ffprobe -of json -show_streams  {$input}   | grep rotate");
    

    
if(!empty($dd)){
    

    
$dd=explode(":",$dd);
    
$rotate=str_replace(",","",str_replace('"',"",$dd[1]));
    

    
if($rotate=="90")return $return;
    

    
else if ($rotate=="180") return ", transpose=2,transpose=2 ";
    

    
else if($rotate == "270") return ", transpose=2 ";
    
}

    Currently above script is supporting "flv","avi","mp4","mkv","mpg","wmv","asf","webm","mov","3gp","3gpp" extensions, also the script is supporting the resulting .mp4 file to play on all browsers and devices.

    For query :

    ffmpeg -i <server path="path">/g9zyy2qg54qp1l5spo2-mergedFile.webm -strict -2 -vcodec libx264 -preset slow -vb 500k -maxrate 500k -bufsize 1000k -vf 'scale=-1:480 ' -threads 0 -ab 64k -s 640x480 -movflags faststart -metadata:s:v:0 rotate=0 <server path="path">/g9zyy2qg54qp1l5spo2-mergedFile5.mp4
