I need to develop a Linux based OMAP3530 system that can do the following:
- Capture live video (and audio) at D1 resolution (720x480)
- Pass the live video, without a memcopy(), to the DSP to encode into H.264
- Write the H.264 stream (and compressed audio, audio codec TBD) to an SDHC card.
- When not recording the system power needs to drop to 10mW or less.
- The system needs to wake up (timer or stimuli) and being recording again within 1 second of the stimulus.
What Linux should I use as a starting point?
- "Supported" or community?
- If Supported, whose? Does theirs support video capture and power management adequately?
- If Community, which kernel source?
Thanks in advance for your suggestions and comments.
