Hi, I want to play multicast video stream on the imx53 Quick Start Board (Ubuntu 10.04 L2.6.35_11.09.01). But the device can not play it correctly for reasons unknown to me. My network scheme is following:
To play a multicast video on the device, I did the following:
1) Network buffer of the device was increased and IGMP setted to v2
echo 204800 > /proc/sys/net/core/rmem_max
echo 2 > /proc/sys/net/ipv4/conf/all/force_igmp_version
echo 2 > /proc/sys/net/ipv4/conf/default/force_igmp_version
2) imx53 Quick Start Board getting network settings from DHCP service.
3) for playing udp stream to network I used notebook with VLC player running. To run VLC I made the following:
a) Tools->Preferences(Show settings - switch to all)->Stream Output->Access Output. Set "Multicast output interface" and "IPv4 multicast output interface address" to my ip address of notebook network interface.
b) We can play video using next steps. Open "Media" menu, next "Streaming", add video file to list, press button "Stream", press button "Next" on the new opened dialog, select "New destination" to UDP (legacy), press button "Add", set address to 22.214.171.124 and port to 1234, uncheck "Activate transcoding", then press "Stream" button to start streaming video.
4) On the device I try to use the following commands:
gst-launch udpsrc multicast-group=126.96.36.199 auto-multicast=true port=1234 buffer-size=1000000 ! decodebin2 use-buffering=true max-size-buffers=32 max-size-bytes=1000000 ! mfw_v4lsink
gst-launch udpsrc multicast-group=188.8.131.52 auto-multicast=true port=1234 ! decodebin2 ! mfw_v4lsink
The log of commands:

On log it is clear that the video was detected, but we could not see anything on the screen. Also tried to reproduce the flow through the totem video player (see the screenshots in the enclosure), but also no success.
Could Somebody help with this problem?
Someone tried to play the video using multicast UDP streaming?
