try it out and good luck.

That doesn't help anything. current gstreamer which comes with ubuntu 22.04 doesn't have  vapostproc/vah264enc
But I tried below and it didn't help. I see same issue of getting stuck

gst-launch-1.0 ximagesrc use-damage=0 show-pointer=false ! video/x-raw,framerate=30/1 ! queue ! vaapipostproc width=1920 height=1080 ! queue ! vaapih264enc dct8x8=true cabac=true rate-control=cbr bitrate=1000 keyframe-period=30 max-bframes=1 ! queue ! flvmux name=mux ! queue ! progressreport ! queue ! rtmpsink sync=false async=true location="rtmp://xxxxx" pulsesrc do-timestamp=true device="alsa_output.pci-0000_00_1b.0.analog-stereo.monitor" ! queue ! audioconvert ! queue ! voaacenc bitrate=128000 ! queue ! mux.

 I can broadcast my desktop to a rtmp server successfully using 

```
gst-launch-1.0 ximagesrc use-damage=0 show-pointer=false ! video/x-raw,framerate=30/1 ! videoconvert ! queue ! x264enc ! queue ! flvmux name=mux ! queue ! progressreport ! queue ! rtmpsink sync=false async=true location="rtmp://xxxxxx" pulsesrc do-timestamp=true device="alsa_output.pci-0000_00_1b.0.analog-stereo.monitor" ! queue ! audioconvert ! queue ! voaacenc bitrate=128000 ! queue ! mux. 
```



But If I try to do same using hw acceleration vaapi then it does not work !! 


```
gst-launch-1.0 ximagesrc use-damage=0 show-pointer=false ! video/x-raw,framerate=30/1 ! videoconvert ! queue ! vaapih264enc dct8x8=true cabac=true rate-control=cbr bitrate=1000 keyframe-period=30 max-bframes=1 ! queue ! flvmux name=mux ! queue ! progressreport ! queue ! rtmpsink sync=false async=true location="rtmp://xxxx" pulsesrc do-timestamp=true device="alsa_output.pci-0000_00_1b.0.analog-stereo.monitor" ! queue ! audioconvert ! queue ! voaacenc bitrate=128000 ! queue ! mux.
```


It is just stuck at below if i use hw acceleration:
