[ROM][SM-T31x][JB/KK][4.3.1/4.4.2] CyanogenMod unofficial builds thread but I don't have enough posts)
I was still having issues with the front camera recording video in my builds of your CM11 port, not that I really use it but I know lots of people were reporting issues with the cameras and saw a fix committed, so I thought I'd have a poke around.
It looks like a discrepency between the HAL and the media_profiles.xml config for the front camera frame rates. Your recent commit to android_device_samsung_lt01-common/camera/exynos_camera.c changes the front camera frame rates to 25,15 but
android_device_samsung_smdk4412-common/config/media_profiles.xml still uses 30 fps as the frameRate for all the EncoderProfiles for the front camera CamcorderProfile.
Changing media_profiles.xml to use 25 fps fixes front camera recording for me; not sure if this is the correct fix though, can't find definitive information on the supported frame rates for the SR130PC20.
