  • What is wrong with the following ffmpeg command

    14 août 2013, par Brad

    What is wrong with the following ffmpeg command. Originally this had -sameq instead of the -qscale:a 0

    Command :

    ffmpeg -loglevel debug -threads 4 -i sample-in.mpg -ss 00:00:01 -t 00:00:05 -f image2 -y sample-frames/frame%d.png -acodec copy -qscale:a 0  -y sample.mp3

    Output

    I did a few edits removing the -sameq and replacing it with -qscale:a 0 which probably is wrong.

  • Is there a media server which just receives any rtsp streams and serves them ?

    7 mai 2015, par Given92

    I have some rtmp streams served over nginx-rtmp-module and the number of them will be changed dynamically.

    But for the limit of client, I have to serve them in rtsp protocol. Obviously, It’s not supported by nginx-rtmp-module. So I plan to run a rtsp server in the same device, and convert the rtmp stream into rtsp stream with ffmpeg, then send the rtsp stream to the rtsp server. So that client could play the stream from the rtsp server.

    The trouble is that I could not found a stable server which just receive any rtsp streams and serve them.

    There is an example that fits all my need but it’s a little unstable.

    I run it in verbose mode and send stream with :

    ffmpeg -i rtmp://localhost/<name> -codec copy -ar 44100 -ac 1 -f rtsp rtsp://localhost:5545/<name>
    
</name></name>

    and play the stream with :

    gst-launch-0.10 playbin2 uri=rtsp://<server>/<name>
    
</name></server>

    The video does not appear and there are some repeated warnning like this :

    WARNING: from element /GstPlayBin2:playbin20/GstURIDecodeBin:uridecodebin0/GstDecodeBin2:decodebin20/GstRtpVorbisDepay:rtpvorbisdepay0: Could not decode stream.

    When I try :

    gst-launch-1.0 playbin uri=rtsp://<server>/<name>
    
</name></server>

    it is stuck and no video appear :

    I’m not sure whether ffmpeg or rtsp-server is the problem, does anyone have some ideas ?

    Thanks very much.

  • FFmpeg does not always fully concat video ?

    25 juin 2014, par user3550401

    I’m trying to concat two video clips, sometimes i end up with only three fourths of the video, sometimes I only get one half, and sometimes i manage to get the whole thing. Anyone ever deal with this ? Here is my ffmpeg command :

    ffmpeg -i "concat:videos/clip1.ts|videos/clip2.ts"  -ar 44100  -b:a 128k -b:v 800k -vcodeclibx264 -bsf:v h264_mp4toannexb -f mpegts -t 120 videos/output.ts

    I just dont understand why sometimes it works perfectly and other times i only get part of the video.
