Video capture demo application

Other Parts Discussed in Thread: TVP5146M2

 Hi,

I am using TI EVM for OMAP 3530. I tried to run "saMmapLoop" video capture application supplied with the EVM. I am able to successfully capture video through USB webcam. When I run the application for composite input I receive "Cannot allocate memory error" as below:

 

root@omap3evm:/opt/video_examples# ./saUsrMmapLoopback

<6>tvp514x 3-005c: tvp5146m2 found at 0xb8 (OMAP I2C adapter)

tvp514x 3-005c: tvp5146m2 found at 0xb8 (OMAP I2C adapter)

 

Capture: Opened Channel

Capture: Current Input: COMPOSITE

Capture: Input changed to: COMPOSITE

Capture: Capable of streaming

Cannot allocate memory: Cannot allocate memory

Error in opening capture device for channel 0

I have boot linux using tftp and mount file system using NFS. Please suggest a solution.
Thanks,
Dhaval

    Hi, Dbaval,

    Were you able to run the saMmapLoop as you described? I was not able to I got VIDIOC_ENUMINOUT invalid argument error when I try to run it. I am using OMAP 35x EVM Rev. G board. Also can you tell me how did you do it with the USB webcam. Thanks.
