userland's Introduction

This repository contains the source code for the ARM side libraries used on Raspberry Pi. These typically are installed in /opt/vc/lib and includes source for the ARM side code to interface to: EGL, mmal, GLESv2, vcos, openmaxil, vchiq_arm, bcm_host, WFC, OpenVG.

Use buildme to build. It requires cmake to be installed and an ARM cross compiler. For 32-bit cross compilation it is set up to use this one: https://github.com/raspberrypi/tools/tree/master/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian

Whilst 64-bit userspace is not officially supported, some of the libraries will work for it. To cross compile, install gcc-aarch64-linux-gnu and g++-aarch64-linux-gnu first. For both native and cross compiles, add the option --aarch64 to the buildme command.

Note that this repository does not contain the source for the edidparser and vcdbg binaries due to licensing restrictions.

hello_mmal_jpeg fails with images from USB webcam

Describe the bug
Sometimes, perfectly valid jpeg images fail to decode. They come from a USB webcam.

$ ./hello_mmal_jpeg.bin frame.jpeg
vc.ril.image_decode:out:0(I420)
 type: 3, fourcc: I420
 bitrate: 0, framed: 0
 extra data: 0, (nil)
 width: 736, height: 368, (0,0,724,362)
start decoding
stop decoding

For reference, a typical successful run of the program looks like this:

$ ./hello_mmal_jpeg.bin test-image.jpg 
vc.ril.image_decode:out:0(I420)
 type: 3, fourcc: I420
 bitrate: 0, framed: 0
 extra data: 0, (nil)

To reproduce

The above image isn't viewable with most programs. It can be fixed with this ffmpeg command, which turns a Motion JPEG frame into a full JFIF image file:
ffmpeg -i frame-og.jpg -c:v copy -bsf:v mjpeg2jpeg frame-fixed.jpg

Both of them fail when inputted to hello_mmal_jpeg.bin. Other images work fine.

probe_sensor in raspiraw.c is leaking

If the while loop does not find any sensor, the function still return the last sensor searched, instead of NULL.

raspivid locks up above 202 fps for unclear reasons

You state that in this posting:
https://www.raspberrypi.org/forums/viewtopic.php?f=43&t=204775#p1270144

This is major blocker of bringing over raspiraw high framerate features from raspiraw (v2 camera can do easily 640x480 at 240fps with raspiraw, and even 640x215 at 420fps with very few frame skips; v1 camera can do 640x64 at 665fps with raspiraw without frameskips).

I would expect raspivid to show >500fps with v1 camera at least if this blocker issue will be fixed.

Capping raspivid fps at 120 is too conservative for v2 camera

See several videos taken with raspivid at 180fps (with the help of I2C commands injected later), starting here:
https://www.raspberrypi.org/forums/viewtopic.php?f=43&t=204775#p1275741

Please increase cap value to 180 at least, that will allow everybody with standard raspivid to take 640x480 videos at 180fps (and not only at 120fps, or 90fps as documented).
