Hi Ohheyitscortex, would u plz share a video how action camera works with mobile encoder?
Or How other camera works a live stream as u mentioned ? so that we may have a comprehensive understanding of the case you described.
Hi ytao - sorry for the late reply, I've been away over christmas/new years.
I can't personally provide you with a demonstration video, as I don't have any other action cameras, I sold them after I got my OA3.
Basically, a lot of us use these kind of cameras in order to stream to Twitch/YouTube, etc. This is referred to as "IRL" (In real life) streaming, and is a burgeoning market segment, it's starting to become more and more popular. Some people will use their phones for this purpose, others often use the Sony FDR-X3000. Some also use GoPro 8/9/10/11, etc.
These cameras mentioned above offer an HDMI out, which is typically what is being used, this output is sent to a mobile encoder like the LiveU or TBS2603 - or in my case, the Muxer One, a product made by the replier above me, kevmo314.
This signal is then encoded and sent on to an intermediary server or direct to the streaming platform, this is taken care of by the mobile encoder.
Regarding your camera, the Muxer One, which runs Linux, can pick up the camera UVC output, but as kevmo314 has described above, only seems to be able to negotiate MJPG profile, whereas on windows it has a much higher quality H264 negotiation take place. Firstly, we'd love it if you could fix whatever is causing this issue, so that we can use the higher quality H264 output on Linux, for the aforementioned streaming purposes.
Secondly, and even more ideally, if you could allow us access to parameters while in UVC webcam mode, for instance, the ability to adjust the FOV, colour profile, bitrate and most especially, the stabilisation - as we are all typically walking around with these cameras on our shoulder or a selfie stick, or mounted to a bike/motorbike/vehicle, etc. As such, stabilisation is an absolute must. Any extra parameters you can expose for us would be super appreciated, but stabilisation is most important.
I'm not sure if based on your pin configuration for the USB C port, whether it's possible to allow charging/UVC webcam mode + external mic at the same time over a USB adapter, but that would also be extremely helpful.
Thanks! |
