OMX capture encode application at 720p

Hi,

I am using the OMX capture encode application for capturing video at 720p. But after executing the application, the output video created has the resolution of 1920x1080p. I want the output video at 1280x720p .

I have attached the logs

root@dm814x-evm:~/app#
root@dm814x-evm:~/app# cat /sys/devices/platform/vpss/display0/mode
720p-60
root@dm814x-evm:~/app#

root@dm814x-evm:~/app# ./capture_encode_a8host_debug.xv5T -o xyz.h264 -m 720p -f
 60 -b 1000000 -d 0 -n 1000
output file: xyz.h264
bit_rate: 1000000
frame_rate: 60
num_frames: 1000
mode: 720p
display_id: 0

    Hi Debashish,

    You are seeing 1920x1080 from encoder and on display because, De-Interlacer output and encoder input is hard-coded to output 1920 and 1080 (check IL_CLIENT_ENC_WIDTH and IL_CLIENT_ENC_HEIGHT).

    You can simply redefine these two defines in ilclient_utils.h as shown below and rebuild the application

    #define IL_CLIENT_ENC_WIDTH (1280)
    #define IL_CLIENT_ENC_HEIGHT (720)

    You should be able to see 72p video.

    Thanks

    Ram
