bug: wrong 25 fps on newly fully flashed jooan camera

[nicolasroche898]

repro:
download full firmware for jooan a6m camera, flash full
go to web ui streamer:

seen: 25fps for stream0 and stream1
expected: 15fps for stream0 and stream1

camera doesn't support 25fps.
this creates streaming and recording problems because player doesn't get the correct frame rate.

Open web console, check initial request and response to populate the form. Does it receive 25 fps from the streamer?

[nicolasroche898]

yes it receives 25fps from the websocket upon opening the config page. tested on freshly flashed camera:

{"stream0":{"audio_enabled":true,"bitrate":3000,"buffers":2,"enabled":true,"format":"H264","fps":25,"gop":20,"height":720,"max_gop":60,"mode":"SMART","profile":2,"rotation":0,"rtsp_endpoint":"ch0","width":1280},"stream1":{"audio_enabled":true,"bitrate":1000,"buffers":2,"enabled":true,"format":"H264","fps":25,"gop":20,"height":360,"max_gop":60,"mode":"SMART","profile":2,"rotation":0,"rtsp_endpoint":"ch1","width":640},"audio":{"input_agc_compression_gain_db":0,"input_agc_enabled":false,"input_agc_target_level_dbfs":10,"input_alc_gain":"not supported on this plattform","input_bitrate":40,"input_enabled":true,"input_format":"OPUS","input_gain":25,"input_high_pass_filter":false,"input_noise_suppression":0,"input_sample_rate":16000,"input_vol":80},"image":{"ae_compensation":128,"anti_flicker":2,"backlight_compensation":null,"brightness":128,"contrast":128,"core_wb_mode":0,"defog_strength":null,"dpc_strength":null,"drc_strength":null,"highlight_depress":0,"hue":null,"max_again":160,"max_dgain":80,"running_mode":0,"saturation":128,"sharpness":128,"sinter_strength":128,"temper_strength":128,"wb_bgain":0,"wb_rgain":0}}

cat /etc/prudynt.cfg
also shows:
fps: 25;
for stream0, not commented

[nicolasroche898]

(after modifying fps from web ui)
sensor fps is wrong:

# grep -e " :" -e fps /etc/prudynt.cfg 
general : 
rtsp : 
sensor : 
  fps = 25;
image : 
stream0 : 
  osd : 
  fps = 15;
stream1 : 
  osd : 
  fps = 15;
stream2 : 
  jpeg_idle_fps = 1;
  fps = 25;

for reference:

# sensor all
name:      sc1a4t
chip_id:   0xda4d
i2c_addr:  0x30
width:     1280
height:    720
min_fps:   5
max_fps:   15
version:   H20230921a

i think 25 is default fps in prudynt. @gtxaspec can we add initialized fps in exported sensor driver values? so that prudynt could get the real values from /proc/jz/sensor/fps ?

[nicolasroche898]

still occurring on BUILD_ID="master+7328f82, 2024-10-31 06:19:03 +0000"

this causes recorder and streamer to create wrong stream advertising 25fps, which are skipping upon playback

this is a problem now also for all 30fps cams such as Wyze V3 default, ref #245
