RDK4.0 decode-display

Li Michelle

Hi,

we use RDK4.0.

I run the usecase VDEC+VDIS, use the ini file as following:

[file00]
path      = /opt/dvr_rdk/ti816x/data/720P60/720P60.h264
width     = 1280
height    = 720
enable    = 1
codec     = h264
numbuf    = 0
displaydelay    = 0

[file01]
path      = /opt/dvr_rdk/ti816x/data/720P60/720P60.h264
width     = 1280
height    = 720
enable    = 1
codec     = h264
numbuf    = 0
displaydelay    = 0

[file02]
path      = /opt/dvr_rdk/ti816x/data/720P60/720P60.h264
width     = 1280
height    = 720
enable    = 1
codec     = h264
numbuf    = 0
displaydelay    = 0

[file03]
path      = /opt/dvr_rdk/ti816x/data/720P60/720P60.h264
width     = 1280
height    = 720
enable    = 1
codec     = h264
numbuf    = 0
displaydelay    = 0

But the display is not normal, and it constantly pintf the error information on console.

The error information is:

[m3video] 17799:DECLINK::links_m3video/iva_dec/decLink_h264.c:[379]::INTERNAL ERROR:-1
[m3video] ALGPROCESS FAILED:STATUS
[m3video] outArgs->viddec3OutArgs.extendedError for channel 0 Error: 0x401
[m3video] Sequence called number 23

what's the problem?

Did you check h264 stream? It looks to be corrupted. It seems decoder did not get correct header.

Hi,

The h264 file is the data which is supported by RDK package. I play it with Elecard, it's normal.

The header is producded on running the usecase.

Hi,

I have another problem, can you help me?

You say the stream maybe have a problem, so I change the stream from 720P60 to D1, there are 9 files; It can normally display.

I use the Layout is 3x3, if I dynamicly change the Layout to 2x2, it can only display win0 and win1, why not win2 and win3?

If I dynamicly change the Layout from 2x2 to 3x3, it can only display win0, win4, win6, the other can not.

Why?

Hi,

1, you need to be in the INI file change the value of numbuf to 4.

2, run VDEC+VDIS, select the Y to generate the headeer file.

3, you need to try to change 720P60 into 1080P30, this file in TI ezsdk root file system

Hi,

about the layout, please run the 16 channel, vcap+venc+vdec+vdis usecase, and then try to change layout.
