Scripts

rec.sh - Record screen or window  with VAAPI(intel I420 or NV12), OMX(radeon NV12), software (x264enc I420 or NV12) to mkv file, with or without sound.
Require zenity, gstreamer-1.0, gst-omx, gstreamer-vaapi-plugin, intel-vaapi or mesa-omx, pulseaudio.

Run with -s argument to enable sound recording /rec.sh -s
         -d to set dir for saving *.mkv /rec.sh -d /tmp
         -n for nogui mode /rec.sh -n=v for vaapi; -n=o for omx; -n=x for x264enc
         -x nubmer of x-server  /rec.sh -x 0
         /rec.sh -s -d /tmp -n=o record screen with sound using omx and save to /tmp
         -h show help message



gsttwich.sh - Record screen or window  VAAPI(intel I420 or NV12), OMX(radeon NV12), software (x264enc I420 or NV12) and streaming it to twich.

Run with
         -n for nogui mode /rec.sh -n=v for vaapi; -n=o for omx; -n=x for x264enc
         -x nubmer of x-server  /rec.sh -x 0
