This is the pipeline we used in DVB demos, courtesy of Evariste, F5OEO:
mkfifo videots
mkfifo fifo.264
mkfifo spectrum.iq
mkfifo leandvb.iq
#rtl_sdr -p 20 -g 35 -f 1245000000 -s 1000000 - |tee spectrum.iq >leandvb.iq &
sudo ./limerx -s 1000 -f 1245000 -g 80 -t u8|tee spectrum.iq >leandvb.iq &
./leandvb.embedded --cr 7/8 --sr 500000 -f 1000000 -d >videots <leandvb.iq &
./kisspectrum -i spectrum.iq -t u8 -s 1000000 -r 25 &
ts2es -video videots fifo.264 &
./hello_video.bin fifo.264
Just put the above in a shell script and assumes all those binaries are available, course. Mostly from:
(left commented out rtl_sdr command in place to show where it got replaced)
