Correct the typo: the only one video clip from H264 video clip play without any issue. This issue also happen in others video format like VC1, VP8.

I'm runninng the test on using BXT.

for color balance setting, need gstreamer to update some code as below. not use multiple filter buffers, but one filter buffer with multiple elements for different items.
{

        VAProcFilterParameterBufferColorBalance color_balance_param[4];
        VABufferID color_balance_param_buf_id;
        float value;
        uint32_t i, count;
        int8_t status;

        VAProcFilterCapColorBalance color_balance_caps[VAProcColorBalanceCount];
        unsigned int num_color_balance_caps = VAProcColorBalanceCount;
        va_status = vaQueryVideoProcFilterCaps(m_vaDisplay, context_id,
                                               VAProcFilterColorBalance,
                                               &color_balance_caps, &num_color_balance_caps);

        count = 0;
        printf("Color balance params: ");
        for (i = 0; i < num_color_balance_caps; i++) {
            if (color_balance_caps[i].type == VAProcColorBalanceHue) {
                color_balance_param[count].attrib  = VAProcColorBalanceHue;
                value = 150;// read_value_float(g_config_file_fd, "COLOR_BALANCE_HUE", &value);
                printf("Hue: ");
            } else if (color_balance_caps[i].type == VAProcColorBalanceSaturation) {
                color_balance_param[count].attrib  = VAProcColorBalanceSaturation;
                value = 1;// read_value_float(g_config_file_fd, "COLOR_BALANCE_SATURATION", &value);
                printf("Saturation: ");
            } else if (color_balance_caps[i].type == VAProcColorBalanceBrightness) {
                color_balance_param[count].attrib  = VAProcColorBalanceBrightness;
                value = 1;// read_value_float(g_config_file_fd, "COLOR_BALANCE_BRIGHTNESS", &value);
                printf("Brightness: ");
            } else if (color_balance_caps[i].type == VAProcColorBalanceContrast) {
                color_balance_param[count].attrib  = VAProcColorBalanceContrast;
                value = 1;// read_value_float(g_config_file_fd, "COLOR_BALANCE_CONTRAST", &value);
                printf("Contrast: ");
            } else {
                continue;
            }

            color_balance_param[count].value = value;
            color_balance_param[count].type  = VAProcFilterColorBalance;
            count++;

            printf("%4f,  ", value);
        }

        va_status = vaCreateBuffer(m_vaDisplay, context_id,
                                   VAProcFilterParameterBufferType, sizeof(color_balance_param), 4,
                                   color_balance_param, &color_balance_param_buf_id);

        filter_param_buf_id = color_balance_param_buf_id;
    }

it has two driver issues for this problem. I am working on them.
1, VEBOX sync issue. if add vaSyncSurface before output the frame, it works rightly
2, vaPutImage() with input P010 surface don't work and sometimes make GPU hang up. but I am wondering why gstreamer do this during its startup.

Use gst-launch-1.0 filesrc location=/root/video_422/Puppies_640x320_i420.yuv ! videoparse format=i420 width=640 height=320 ! vaapipostroc hue=100 ! vaapisink
to test on all platforms, and same green green stripes appears on KBL&APL&SKL, and appears occasionally.

Any update for this issue?

The issue disappear when disable libdrm cache, root cause is still unknown

Tested in APL-I and HSW platform, the issue can't reproduce anymore.
Thank you for the fixed. :)

Ops...It only fixed in HSW platform. The APL-I (BXT) still can reproduce the issue.

Sorry. My mistake forgot to patch code in my BXT system. It is truly fixed it. Run twice and confirmed fixed in BXT. Thank you.

According to the comments in va_vpp.h, I think it is mandatory.

 * This buffer defines color balance attributes. A VA buffer can hold                                                                             
 * several color balance attributes by creating a VA buffer of desired                                                                          
 * number of elements
