Unable to access stream on ZCam K1 Pro #67

Closed doughtmw closed 2 years ago

doughtmw commented 2 years ago

Thanks for the great work on this repo, @summershrimp. I'm trying to access the live feed for the ZCam K1 Pro camera in OBS, but am running into some errors and am not able to receive a stream.

I've included the relevant log(s) below for the stream mode with "Don't Check Device Status" toggled off/on.

  1. Disabled:

Thanks in advance for any insight.

Hi, It seems that the ssp protocol of K1 Pro does not fully compatible with E2 series. The audio metadata returns an unknown encoder type of zero

ssp a meta: uinit: 1024, timescale:48000, encoder:0, bitrate:128000, channel:2, sample_rate:48000, sample_size:2048

On libssp's definition, 0 means unknown

#define AUDIO_ENCODER_UNKNOWN   (0)
#define AUDIO_ENCODER_AAC   (37)
#define AUDIO_ENCODER_PCM   (23)

Currently obs-ssp only support AAC audio stream and E2 series always use them.

I'd ask the libssp's original developers for more info about K1 pro

Thanks for the prompt response and suggestions, @summershrimp! I'll reach out to the libssp devs to see if they've run into this issue before. Thank you!
