What steps will reproduce the problem?
1. Chose a default video quality that is a higher resolution than the device
camera. 720p while using iPhone 4s front facing camera.
2. Initiate a video session with a device that supports 720p.
3. Notice that the video is stretched.
What is the expected output? What do you see instead?
Video should be cropped into new aspect ratio rather than stretched.
What version of the product are you using? On what operating system?
Latest Doubango and iOS NGN stack.
Please provide any additional information below.
When a video session is negotiated at a resolution higher than the default
device camera resolution. The video is upscaled to fit the negotiated video
size. However, the upscaling is stretching the video rather than cropping.
I have tracked down the issue down to this method in tdav_converter_video.cxx
static tsk_size_t tdav_converter_video_libyuv_process(tmedia_converter_video_t*
_self, const void* buffer, void** output, tsk_size_t* output_max_size)
It appears that this method assumes that the source and destination aspect
ratio are the same during the scaling process.
