DVR_RDK RPE Add additional audio encoding

DM8168 in the audio algorithm (DVR-RDK has integrated AAC enc, DEC) using the RPE (remote program Call) mechanism, the introduction of this mechanism can refer to the document in Ti_tools/rpe, or refer to the author's blog and thesis. 1. Update the build environment variable

/remote-processor-execute/makerules/env.mk

L42:

#####################################################

# Codecs Paths

#####################################################

# AACDEC-AAC Decoder

Aaclcdec_path =$ (external_sw_root)/c674x-aaclcdec_01_41_00_00_elf

Aaclcdec_include =$ (Aaclcdec_path)/packages

# AACENC-AAC Encoder

Aaclcenc_path =$ (external_sw_root)/c674x_aaclcenc_01_00_01_00_elf

Aaclcenc_include =$ (Aaclcenc_path)/packages

#

# <integrator>: Add more codec Pathshere.

#

2. Add codec to compile list:

Ti_tools/rpe/remote-processor-execute/src/config/codecs.mk

Include_codec_interfaces = Aaclcdecaaclcenc

3. Updating the client configuration file

Ti_tools/rpe/remote-processor-execute/src/config/client_config.c

/* GET structure definitions for Aaclcaudio Decoder Interface */

#include <ti/sdo/codecs/aaclcdec/iaacdec.h>

#include <ti/sdo/codecs/aaclcenc/imp4aacenc.h>

Because the AAC enc and DEC are already integrated, the classes that use the XDm interface have already been defined, and if you want to run other codec at the same time, you may need to add them.

4. Update the server configuration file

ti_tools/rpe/remote-processor-execute/src/config/server_config_c67x.c

(1) Imitate the const Xdmserver_serverconfig ti_aacdec_serverconfig{} to write your own classconfigratiion

(2) Update:

Const rpe_serverconfig*rpe_serverconfigarray[] =

{

(const rpe_serverconfig *) & Ti_aacdec_serverconfig,

(const rpe_serverconfig *) & Ti_aacenc_serverconfig,

& Rpe_endserverconfig

};

Of course, include the necessary header files as well.

5. Modify/dvr_rdk/rules.make

L101 Line:

# Audio Framework (RPE) and Codecs

Aaclcdec_path: =$ (ti_sw_root)/codecs/c674x_aaclcdec_01_41_00_00_elf

aaclcdec_path= "${aaclcdec_path}" \

Aaclcenc_path= "${aaclcenc_path}"

L373:

Export Aaclcdec_path

Export Aaclcenc_path

6. Add a library

Dvr_rdk/makerules/rules_c674.mk

L192:

Lib_paths + = $ (Rtslib_path) \

$ (aaclcdec_path)/packages/ti/sdo/codecs/aaclcdec/lib/aacdec_tii_lc_elf.l64p\

$ (Aaclcenc_path)/packages/ti/sdo/codecs/aaclcenc/lib/mp4aacenc_tij_lc_elf.l67

Add include directory:dvr_rdk/makerules/env.mk

Aaclcdec_include =$ (Aaclcdec_path)/packages

Aaclcenc_include =$ (Aaclcenc_path)/packages

7. Specify the build containing path of RPE on arm side

dvr_rdk/makerules/ includes_a8.mk

L18:

rpe_inc=-i$ (Rpe_path)/include-i$ (Rpe_path)/src/include-i$ (Aaclcdec_path)/packages-i$ (Aaclcenc_PATH)/packages-I $ (Xdais_path)/packages

8. Dvrrdk_03.00.00.00/dvr_rdk/mcfw/src_bios6/bios_c6xdsp.cfg not sure

program.sectmap["Aacencprogram"] = "Dsp_code_mem";
