HTML-код
- Опубликовано: 6 сен 2024
- The video is transmitted by broadcasting wifi packets with video data into the air. This way the video connection is truely unidirectional. No acknowledgements are sent from receiver to transmitter. The video was captured with a packet loss rate of 2.5%. For more details see befinitiv.word...
hii.. i just see " Signal(card 0) : " om my RX display, what should i do? i just using command in consule with gtreamer and TX/RX code from befi .
hi. could you please post the complete setup including the command lines? (preferably on my blog)
@@kassenbon wooww... that's ur blog... cooll.. love it :), i am new in gstramer, i am using tx/rx with 2 laptop with debian linux (both of them ), here is my command :
TX :
gst-launch-1.0 -v -e videotestsrc ! x264enc bitrate=1024 speed-preset=superfast qp-min=30 tune=zerolatency ! h264parse ! rtph264pay config-interval=3 pt=96 ! fdsink | ./tx -f 1024 wlx20e6170b1b99
RX:
./rx -f 1024 wlp3s0 | gst-launch-1.0 -v fdsrc ! h264parse ! queue ! avdec_h264 ! queue ! autovideosink async-handling=true
are you on Twitter?
I'm sorry but I don't use Twitter
kassenbon No worries! I'll just have to get an account so I can interact on your blog. Excellent work. We are looking to enable the FPV drone racing circuit... so this is on point with the type of solution we will need. Very cool keeping Penumbra alive! We could in theory run several of these tx sessions tuned to more granular rx clients by changing the radiotapheader I assume?
At this point everything I did is still untested. It should in theory be better than a hostapd solution (initial tests showed that to be true) but further tests are required until all corner cases are well known. So please don't use this and destroy your device during a race :) Concerning the multi-session thing: Please take a look at befinitiv.wordpress.com/2015/02/26/improved-retransmission-scheme-and-multiplexing/ Yesterday I added a "port" feature that should do exactly what you are looking for
kassenbon haha don't worry about the birds! They are durable. I am open to being a gunnea pig. I made an attempt at getting your code to compile on OSX, but I have not got it to transmit quite yet. I attempted to use the built in Broadcom cards. I assume they would need some sort of fcsfail love equivalent.
