[mfw_isink]What is this problem (vssconfig-->format=RGB3)

[tongchunyang]

Dear FSL All

I have met a problem about playing videos by gst-fsl-plugin mfw_isink.

The Detail just like below.

1, OK playing status image with vssconfig-->format=RGBP by mfw_isink

------------------------------------------------------------------------------------------------

①　/usr/share/vssconfig

　　# vss device definition

　　# Master=DVI, Slave=TV

　　# please add "video=video=mxcdi1fb:YUV444,720P60 video=mxcdi0fb:RGB24,1024x768M-16@60" to kernel startup command line

　　# master display

　　[master]

　　type = framebuffer

　　format = RGBP

　　fb_num = 1

　　main_fb_num = 0

②　/root/test.sh script

　　#! /bin/sh

    export VSALPHA=1

    gst-launch filesrc location=WhereTheHellIsMatt_720p.mp4 typefind=true ! aiurdemux ! vpudec ! mfw_isink axis-top=100 axis-left=100 disp-width=800 disp-height=600

2, Flickering playing status image with vssconfig-->format=RGB3 by mfw_isink

------------------------------------------------------------------------------------------------

①　/usr/share/vssconfig

　　# vss device definition

　　# Master=DVI, Slave=TV

　　# please add "video=video=mxcdi1fb:YUV444,720P60 video=mxcdi0fb:RGB24,1024x768M-16@60" to kernel startup command line

　　# master display

　　[master]

　　type = framebuffer

　　format = RGB3

　　fb_num = 1

　　main_fb_num = 0

②　/root/test.sh script

　　#! /bin/sh

    export VSALPHA=1

    gst-launch filesrc location=WhereTheHellIsMatt_720p.mp4 typefind=true ! aiurdemux ! vpudec ! mfw_isink axis-top=100 axis-left=100 disp-width=800 disp-height=600

Who can tell me what is the reason about this problem for mfw_isink?

1, When playing the video with screen size set over 640x480(include this size), it must be flickering or strange color.

2, When playing the video screen screen size set less than 640x480, it palys normally and with correct color.

The gst-fsl-plugins' version is 3.0.7

Could anyone help for this problem?

All right.

I have just fixed this problem

Reason:      mfw_gst_vss_common.c can not supply to convert the RGB24(RGB3) to correct pixel format.

File:            gst-fsl-plugins-3.0.7/libs/vss/mfw_gst_vss_common.c

Function:     int fmt2bit (unsigned long fmt)

Fixing:        Line 147 adding

                 case IPU_PIX_FMT_RGB24:  // added by TongChunyang for fixing the problem of vssconfig set as RGB3

Evidence:

1, bug status log

2, fixed status log
