RTSP - low bitrate about wz_mini_hacks HOT 21 CLOSED

@Vendo232 what are you using to measure the bitrate?

from wz_mini_hacks.

Can you try to ffmpeg -i <file> to compare between RTSP fw and wz_mini?

this is what i show from wz_mini:

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'test.mp4':

you can use the command ffmpeg -i rtsp://user:pass@ip:8554/unicast -acodec copy -vcodec copy test.mp4 to record

from wz_mini_hacks.

there may be a bug in the v4l2rtspserver when audio is enabled the bitrate is much lower and lots of stream errors, at least for me.

i will try to recompile, and also test a different version of the rtspserver.

this is fixed now

from wz_mini_hacks.

you can achieve the same in VLC player

from wz_mini_hacks.

I`m going to test the new version today

from wz_mini_hacks.

@Vendo232 can you test something for me on your existing install?

from wz_mini_hacks.

If course

from wz_mini_hacks.

open up vlc and start watching the stream, then connect with ssh, and run the following commands on the camera:

/system/bin/impdbg --enc_rc_s 0:48:4:2048
/system/bin/impdbg --enc_rc_s 0:52:4:2048

then monitor the quality

from wz_mini_hacks.

should I look for bitrate?

from wz_mini_hacks.

look at the general image quality and see if it is ok for you compared to stock rtsp and anything else

from wz_mini_hacks.

you can raise the 2048 number up to 8096 if you want

from wz_mini_hacks.

what is the difference between command with 48 and 52? should they be executed toghether everytime?

from wz_mini_hacks.

first one is average and second is max bitrate, you typically do want to set them together if you are changing them

from wz_mini_hacks.

I`m running the RTSP FW + mini RTSP and the cam is very slow.

from wz_mini_hacks.

Oh, i see, yes you are running 2 servers it will slow down since the quality goes up significantly. try stopping one, and run the commands and see if your quality goes up

from wz_mini_hacks.

(the image quality should be identical between the two servers anyway)

from wz_mini_hacks.

from wz_mini_hacks.

trying 8096 on both, it is looking really good

from wz_mini_hacks.

nice. i will issue a new release soon
