Re: [V4L] streamer capture

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hi ,


I am new to Linux world and need to complete a decoder class of V4L driver
in short time.  I can not find step by step information regarding how to
debug a modular driver under Linux.

Can anyone help to let me know how to debug a device driver in Linux
environment such as V4L driver.

Best Regards,

Olive
