Play with VLC

[Mazahir Poonawalla]

Hi All,

I want to stream live video using gstreamer plugins. I am using
Leopardboard where my input camera is attached and video is streamed to
Linux machine.

I am using 2 sets of plugins. I have 2 issues.

1. My 1st query is that when I use this plugin:

*gst-launch -v -e v4l2src always-copy=FALSE input-src=composite
chain-ipipe=true ! video/x-raw-yuv,format=\(fourcc\)NV12, width=640,
height=480 ! queue ! dmaiaccel ! dmaienc_h264 encodingpreset=2
ratecontrol=2 intraframeinterval=23 idrinterval=46 targetbitrate=3000000 !
rtph264pay ! udpsink port=3000 host=192.168.1.102 sync=false
enable-last-buffer=false*

I cannot play on vlc media player. Nothing is being displayed at all when I
type the command:

*vlc udp://@192.168.1.102:3000 *

2. My 2nd query is that when I use this plugin:

*gst-launch -e v4l2src input-src=composite always-copy=FALSE !
video/x-raw-yuv,format=\(fourcc\)NV12,width=640,height=480 ! dmaiaccel !
dmaiperf print-arm-load=true ! dmaienc_h264 encodingpreset=2
targetbitrate=1000000 ratecontrol=2 intraframeinterval=23 idrinterval=46 !
queue ! mpegtsmux name=mux ! queue ! udpsink port=3001 host=192.168.1.102
sync=false enable-last-buffer=false*

I can play live video on vlc player on linux machine using the command:

*vlc udp://@192.168.1.102:3001*

but I get following warnings:

*Too many slices, increase MAX_SLICES and recompile*
*number of reference frames exceeds max (probably corrupt input),
discarding one*
*QPainter::begin: Paint device returned engine == 0, type: 1*

Can anyone please help. Also which one is better to use considering the
fact that "mpegtsmux" is under bad plugin?

Thank you & Regards,

**
