Recording camera frames to file using MPA
-
Hi, is there any existing or planned support for recording camera frames to a file using the MPA like there was using voxl-rtsp?
-
@czarsimon Are you interested in recording the raw frames coming from the sensor (voxl-camera-server) or the compressed h264 stream coming from voxl-streamer?
-
@Eric-Katzfey Ideally I would like to be able to record 4K video while streaming at a lower resolution to save on bandwidth. To answer your question I suppose it would be the h264 stream. Does either app have the ability to export video to a file? I wasn't able to find any references to it in the documentation or looking through the source. Thanks
-
@czarsimon Unfortunately, voxl-streamer does not currently support that, and we don't have a date when it will be added. You are more than welcome to add the feature to voxl-streamer. It shouldn't be too hard. You just "tee" the stream at some point and send to a "filesink" element.

@Eric-Katzfey please tell me how to recording the raw frames coming from the sensor (voxl-camera-server) to a SD card?
-
Raw frames can be had onboard using voxl-logger. For example,
voxl-logger --cam stereo --samples 60will record 60 frames in png format from the stereo camera. The frames are currently stored on /data/voxl-logger/log<XXXX>/run. You'll need to move them to the sdcard.

@Cliff-Wong Thanks Cliff this is great, is the source for this app available? I can't find it on Gitlab.
-
The source lives here in the mpa-tools repo

@Alex-Gardner Sweet, thanks!

@Cliff-Wong Thanks! Happened.
Please tell me how to record video to SD?
