I used from long time mumudvb and one dvb-t pci card to stream TV channels on my network. This is working fine but I've recently add another player that is less powerfull than others so I want to re-encode the video stream.

This is my input stream video :

Input #0, mpegts, from 'udp://@239.1.4.1:8200':

  Duration: N/A, start: 53843.533922, bitrate: N/A

  Program 1025 

    Metadata:

      service_name    : M6

      service_provider: Multi4

    Stream #0:0[0x78]: Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p(tv, bt709), 1920x1080 [   SAR 1:1 DAR 16:9], 25 fps, 25 tbr, 90k tbn, 50 tbc

ffmpeg version 3.0.1
Running on Ubuntu 12.04.5 LTS

And this is my command line to run ffmpeg :

ffmpeg -i udp://@239.1.4.1:8200 -qscale:v:0 7 -c:v:0 mpeg4 -b:v:0 4000k -minrate:v 0 -maxrate:v 4000k -bufsize:v 5000k -s hd720 -c:a copy -f mpegts udp://239.1.24.1:8200?pkt_size=1316

But when I do this, I've got errors like this on my VLC player :

On web-plugin VLC media player - 3.0.3 Vetinari running on Ubuntu 16.04.3 LTS

This is resulting on many glitch on VLC video and after some times audio and video become de-synchronised.

For some reasons, I can't update VLC / FFMPEG / Ubuntu

Can you help me with that ?

Thanks in advance for your time !
