OMAP5 - gstreamer encoding functionality

Hi Alexandra,

Which OS are you using?

With GLSDK6.04 it is possible to use GStreamer as an interface to the HW video encoding/decoding in OMAP5 (Ducati). 

You can see what is integrated in the GLSDK on the following link: http://processors.wiki.ti.com/index.php/GLSDK_Datasheet_OMAP5_6.04.00.02#Multimedia

GST version integrated in GLSDK is 0.1 

Hope this helps you.

Best Regards,

Yordan

Hi Yordan,

The OS I am using is QNX 6.5.0.

Concerning what is integrated in GLSDK, i didn't find anything about supported encoders, i found only decoders. I am interested in the encoders as well.

Concerning the Ducati side,  is there an official repository for the latest Ducati source package?

Thanks!

Alexandra,

If you have a look at the OMAP543x TRM, you can find that IVA-HD is both HW encoder/decoder engine (see Section 6.1 IVA Overview).

Regarding Ducati source package, you can obtain it by downloading all GLSD sources (following the release notes); it is located in ti-glsdk_omap5-uevm_6_04_00_02/component-sources/ipumm_3_00_04_02
Find attached the README file with instructions how to build the  IPUMM binary: 2678.README.txt

Hi Yordan,

Thank you for your answer. I have one more question:

I'm trying to compile the package and I'm getting the following errors regarding undefined symbols. Can you help me with this? 

The error message is in the  file attached. This is my configuration:

# Repo
BIOSTOOLSROOT ?= /opt/ti
REPO  := $(BIOSTOOLSROOT)

# Different tool versions can easily be programmed by defining below variables
# in your environment.
XDCVERSION ?= xdctools_3_25_06_96
BIOSVERSION ?= bios_6_37_03_30
IPCVERSION ?= ipc_3_21_00_07
CEVERSION ?= codec_engine_3_24_00_08
FCVERSION ?= framework_components_3.30.01.07_eng
XDAISVERSION ?= xdais_7_24_00_04

# TI Compiler Settings
export TMS470CGTOOLPATH ?= /home/alexd/ti-glsdk_omap5-uevm_6_04_00_02/ti-devkit/cgt470_5_0_7

I also tried with  framework_components_3_24_00_09 and xdctools_3_30_01_25, but no luck.

Thank you,

Hi Alexandra,

If you haven't done any modifications to the code, this seems like you've missed some environment setting.

I don't have much experience with QNX, but if you use the Ducati sources from GLSDK, you should also set:
DEFAULT_IPUMM_CONFIG=omap5_smp_config
BIOS_VERSION=6_37_02_27
IPC_VERSION=3_21_00_07
IPUMM_VERSION=3_00_04_02
DUCATI_FW_GEN=omap5-m4-ipu.xem4
DUCATI_FW=ducati-m3-core0.xem3
XDC_VERSION=xdctools_3_25_05_94
PLATFORM_IPC=OMAP54XX

Check the Makefile & Rules.make, located in ti-glsdk_omap5-uevm_6_04_00_02, for reference. Instructions under  "Build ipumm. Also, an explicit cleanup target is defined."

You should use the arm-linux-gnueabihf cross compiler. 

Hope this helps.

Best Regards,

Yordan

Hi Yordan,

I am already using arm-linux-gnueabihf cross compiler and those variable were already set.

I tried with those versions, i had a lot of errors and eventually some of the symbols were solved after using the configurations in the makefiles attached.

The still unresolved symbols are the following:

Can you please take a look and tell me if i'm doing something wrong?

Thank you very much,

Hi Alexandra,

Sorry for the delayed response.

You use gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux that comes with the GLSDK, right?

Can you try the following versions of BIOS & IPC:
BIOS_VERSION=6_37_02_27
IPC_VERSION=3_21_00_07

Best Regards,

Yordan

Hi Yordan,

Yes, i use gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux that comes with the GLSDK.

I tried with the versions of BIOS and IPC you suggested, but i get the same error: unresolved symbols.

The list of unresolved symbols  is the same as the one  i give you before.

Before i used the IPC from https://git.ti.com/ipc/ipcdev/trees/2ade08907eae72ebd3d30c9fddd350d79727317f/

The IPC from https://git.ti.com/ipc/ipcdev  didn't work, because it didn't have Tiler.

Thanks,

Alexandra

Hi Yordan,

I finally compiled GLSDK. When I run either of the test applications for encoding and decoding (dce_test and dce_enc_test), I get the following error:

MmRpc_create: Error: open failed, name=/dev/rpmsg-dce

Also, regarding IPC resource manager, i tried to run a test: MessageQApp but get the following error:

Ipc_start: NameServer_setup() failed: -8

ProcId must be less than 0

Ipc_stop: MessageQ_destroy() failed: -8

Is something that I am doing wrong?

Thank you,

    Alexandra

This question is the same as this post: http://e2e.ti.com/support/omap/f/885/t/365219.aspx

Could we discuss this on only one thread?

Regards

Karthik
