pipe OBE-RT to ASI output card

[Federico Allegretti]

I'm trying to pipe the OBE encoded transport stream (perfect in vlc using udp://@:5000) to the ASI output card (/dev/asitx0 device).

I was thinkong of something like:
avconv -threads 0 -i udp://localhost:5000  -mpegts_flags resend_headers -c:a copy -c:v copy -f mpegts -muxrate 700k -flags cgop -sc_threshold 500  -metadata service_provider="FEDERICO" -metadata service_name="ALLEGRETTI"  - | txtest /dev/asitx0 0 105560 0 0 0 0


but got "no frame" ... 

strange that avconv detect h264 video and mp2 audio ....
