Rx mcast_sip_addr question

Hi ALL，

I am using "tx_rtp_video_sample"to send mpegts steam and using "rx_rtp_video_sample.c" to receive the mpegts stream, it can works well.
now I need use mcast_sip_addr in st20_rx_ops to filter the same dst ip steam and found it can't work.

I add "--p_source_ip" and "--r_source_ip" cmd params in rx_rtp_video_sample.c

the tx cmd params:
./TxRtpVideoSample --p_port 0000:03:00.0 --r_port 0000:04:00.0 --p_sip 192.168.1.4 --r_sip 192.168.1.25 --p_tx_ip 239.168.77.20 --r_tx_ip 239.168.77.21 --p_udp_port 20000 --r_udp_port 20000

the rx cmd params:
./RxRtpVideoSample -p_port 0000:03:00.0 --r_port 0000:04:00.0 --p_sip 192.168.1.10 --r_sip 192.168.1.3 --p_source_ip 192.168.1.33 --r_source_ip 192.168.1.26 --p_rx_ip 239.168.77.20 --r_rx_ip 239.168.77.21 --p_udp_port 20000 --r_udp_port 20000

you can see in rx, I used the error p_source_ip and r_source_ip, but it still can get the mpegts stream.

I think the tx source ip params are 192.168.1.33 and 192.168.1.26, but why it can still receiving the data from source ip 192.168.1.4 and 192.168.1.25? thanks!
