I am developing DVR using mcvip for dm365.I would like migrate mcvip to dvsdk3.1.I read sourcecode in mcvip directory and find lsp_files.I want to know if i need lsp_files in dvsdk3.1 and linux2.6.32.I can understand source code of dm365 mcvip.But i couldn't know difference between  c code in lsp_files and orignal c code in linux2.6.32.If i migrate mcvip,how to deal with these .c files in lsp_files.If remove lsp_files in linux2.6.32,do my mcvip work well?

    Hi,

    The lsp_files folder is not really used in the current builds. It is kept there as reference so that user can refer to the changes done in DVR RDK for supporting the multi-channel capture (video and audio) w.r.t. base release of LSP. The key changes that you need to worry about when moving to LSP are related to EDMA programing and audio capture. Please refer to EDMA examples in kernel 2.6.32 and you would need to map those parameters to the EDMA used in Demux part of the McVIP code.

    Meanwhile, i will try to find out if we already have McVIP ported on DM365 kernel 2.6.32. There was work happening on it but not sure if it has gone upstream or in any of the SDKs.

    Hi Anshuman

    Thank you for your help.I appreciated for your work all the time on this forum.

    you say  "The lsp_files folder is not really used in the current builds.It is kept there as reference so that user can refer to the changes done in DVR RDK for supporting the multi-channel capture (video and audio) w.r.t. base release of LSP. ",Does it mean that original files in LSP are revised by DVR RDK for multi-channel capture?

    when I port to 2.6.32,I want to know if  original LSP or linux2.6.32 supports multi-channel capture ?Need i revise those files of same name with DVR RDK's lsp_files for new LSP to support multi-channel capture ?But I don't know where DVR RDK revises for those files in lsp_files .

    Also I look forward to see MCVIP on 2.6.32.If available,please post some messages here.

    Best regards

    Stefan
