Ask for support to create a obs encoder

[PMGZED]

Hi, you helped me to got running this ffmpeg on my radxa zero 3w
now i try to create a obs encoder. Obs work fine with the panfrost driver for send the stream obs need a encoder

i have copy the nvenc encode and change to use the rkmpp eincoder but if the stream try to init the encoder it failed.

the cops ffmpeg-video-encoder calls the avcodec_open2 function. this function return -542398533 but i don know why.
maybe you have a idea?
i have already start a thread in obs forum and discord https://obsproject.com/forum/threads/is-there-a-esay-way-to-add-ffmpeg-with-a-videocodec-as-a-streaming-encoder.182707/

the call of avcidec_open2 are in https://github.com/obsproject/obs-studio/blob/master/plugins/obs-ffmpeg/obs-ffmpeg-video-encoders.c line 13

the value of the settings

	info("settings:\n"
	     "\tencoder:      %s\n"
	     "\trate_control: %s\n"
	     "\tbitrate:      %d\n"
	     "\tcqp:          %d\n"
	     "\tkeyint:       %d\n"
	     "\tprofile:      %s\n"
	     "\twidth:        %d\n"
	     "\theight:       %d\n"
	     "\tb-frames:     %d\n",
	     enc->ffve.enc_name, rc, bitrate, cqp, enc->ffve.context->gop_size, profile,
	     enc->ffve.context->width, enc->ffve.height, enc->ffve.context->max_b_frames);

	return ffmpeg_video_encoder_init_codec(&enc->ffve);

i think the parameter are wrong. can u tell me what the minimum parameter require the encoder need?

Ok i had not permissions vor the rkmpp devices. (how can i set the device rights permanent after every restart i need to change with chmod ? )

so now it dont got a error but the fps brake down to 1 fps but dont know why.
cpu usage is about 25%

is it possible thats the dual use with panfrost for obs and mpp not work well?

set the device rights permanent

https://jellyfin.org/docs/general/administration/hardware-acceleration/rockchip/#configure-on-linux-host

but the fps brake down to 1 fps but dont know why

I also have no experience with ffmpeg-rockchip in obs-studio. You can turn on ffmpeg logging and track what is causing the 1fps.

i have switch to the rock 5b with more power.
if i use the record it works but not if i want to use my stream encoder


ignore the settings on the right side i overwrite them to test in my code

maybe i forgot to set some information?
int profile =0;
int bitrate = 5000;
int keyint_sec = 250;
enc->ffve.context->height = 1080;
enc->ffve.context->width = 1920;
enc->ffve.context->framerate.num = 30;
enc->ffve.context->time_base.num = 1;
enc->ffve.context->pix_fmt = AV_PIX_FMT_NV12;
info("settings:\n"
"\tencoder: %s\n"
"\trate_control: %i\n"
"\tbitrate: %d\n"
"\tkeyint: %d\n"
"\tprofile: %i\n"
"\twidth: %d\n"
"\theight: %d\n"
"\tb-frames: %d\n"
"\tFramerate: %d\n"
"\tTimebase: %d\n"
"\tFormat: %d\n",
enc->ffve.enc_name, rcmode, bitrate, enc->ffve.context->gop_size, profile, enc->ffve.context->width,
enc->ffve.context->height, enc->ffve.context->max_b_frames, enc->ffve.context->framerate.num,
enc->ffve.context->time_base.num, enc->ffve.context->pix_fmt);

There are no special parameters that need to be set. Therefore I think the error is in obs-ffmpeg rather than ffmpeg-rockchip.
