Save Frames For Future Use (UYVY Format)

JSmit77 — Tue, 29 May 2018 17:04:58 GMT

I'm currently trying to sample a set of frames using the UYVY format. As I sample I push them back into a vector. If I try to add more than 10 elements to this vector, librealsense2 throws an exception which terminates the program. Sample code shown below.

Strangely I only have this issue when trying to save using the UYVY format, it seems to work fine using the Y8 format. Originally I had this same issue for saving in any format but the .keep() function resolved it. In the viewer the UYVY format is supported for a single IR sensor; however in order to enable it I must use cfg.enable_stream(RS2_STREAM_INFRARED, -1, 1280, 720, RS2_FORMAT_UYVY, 30); Specifying an index other than "-1" results in a thrown exception. When attempting to retrieve frames using .get_infrared_frame(), specifying an index (e.g. 1 or 2) returns a NULL pointer rather than a frame.

To summarize, I am retrieving frames, but cannot hold on to more than 10 at a time, using standard stl containers, and ".keep()" does not resolve the issue. As I am able to sample and save large quantities of frames in other formats (e.g. 500 rgb frames in 24bit rgb) I am confident I am not running out of memory. Anyone have any ideas ?

Hello,

I use 2.11.0 LibRS and revised rs-capture.cpp sample code to simulate your situation, the code works without problem, please have a try and let me know your feedback.

Also for index of the Left/Right IR, Y8 & Y16 are generated from each stream so if you want to get those two format, you can set stream parameter to 1 or 2. But few of the format is generated through software, if you want to retrieve those format, you have to set the index to 0. you can use the rs-sensor-control.cpp example to list down the available streams. Attached my enumeration from the sample.

Sensor provides the following stream profiles:

0 : Infrared # 2 (Video Stream: Y16 1920x1080@ 25Hz)

1 : Infrared # 1 (Video Stream: Y16 1920x1080@ 25Hz)
