Hi3516a osd 刷新Out of memory问题
我最近在做海思3516a的osd菜单,就像电视机上的频道选择,音量控制那样。
采用的方案是SDL+freetype+SDL_ttf。
osd的刷新放在一个线程中,osd的菜单层次改变,字符串改变,颜色改变放在其他线程中。
下面这段代码是osd刷新的线程。
void *monitor_thread(void *arg)
{
HI_S32 s32Ret;
RGN_ATTR_S stRgnAttrSet[RGN_MAX];
RGN_CHN_ATTR_S stChnAttr[RGN_MAX];
stChn.enModId = HI_ID_VPSS;
stChn.s32DevId = 0;
stChn.s32ChnId = 0;
BITMAP_S stBitmap[RGN_MAX];
TTF_Font *font;
SDL_PixelFormat *fmt;
SDL_Surface *text;
SDL_Surface *temp;
if (TTF_Init() < 0)
{
fprintf(stderr, "Couldn't initialize TTF:%s\n", SDL_GetError());
SDL_Quit();
return (void*)-1;
}
font = TTF_OpenFont("./simhei.ttf", 16);
if (NULL == font)
{
fprintf(stderr, "Couldn't load %d pt font from %s:%s\n", 18, "ptsize", SDL_GetError());
return (void*)-2;
}
fmt = (SDL_PixelFormat*)malloc(sizeof(SDL_PixelFormat));
memset(fmt, 0, sizeof(SDL_PixelFormat));
fmt->BitsPerPixel = 16;
fmt->BytesPerPixel = 2;
fmt->colorkey = 0xffffffff;
fmt->alpha = 0xff;
//创建八个region并Attach到VPSS通道上
for (item_count = 0; item_count < RGN_MAX; item_count++)
{
stRgnAttrSet[item_count].enType = OVERLAYEX_RGN;
stRgnAttrSet[item_count].unAttr.stOverlayEx.enPixelFmt = PIXEL_FORMAT_RGB_1555;
stRgnAttrSet[item_count].unAttr.stOverlayEx.stSize.u32Width = 136;
stRgnAttrSet[item_count].unAttr.stOverlayEx.stSize.u32Height = 18;
stRgnAttrSet[item_count].unAttr.stOverlayEx.u32BgColor = 0x00000000;//0x000003e0;
s32Ret = HI_MPI_RGN_Create(item_count, &(stRgnAttrSet[item_count]));
if (s32Ret != HI_SUCCESS)
{
printf("HI_MPI_RGN_Create failed! s32Ret: 0x%x.\n", s32Ret);
return (void*)s32Ret;
}
stChnAttr[item_count].bShow = HI_TRUE;
stChnAttr[item_count].enType = OVERLAYEX_RGN;
stChnAttr[item_count].unChnAttr.stOverlayExChn.stPoint.s32X = 46;
stChnAttr[item_count].unChnAttr.stOverlayExChn.stPoint.s32Y = 34 + item_count * 18;//position of region
stChnAttr[item_count].unChnAttr.stOverlayExChn.u32BgAlpha = 0;
stChnAttr[item_count].unChnAttr.stOverlayExChn.u32FgAlpha = 128;
stChnAttr[item_count].unChnAttr.stOverlayExChn.u32Layer = 0;
s32Ret = HI_MPI_RGN_AttachToChn(item_count, &stChn, &(stChnAttr[item_count]));
if (s32Ret != HI_SUCCESS)
{
printf("HI_MPI_RGN_AttachToChn failed! s32Ret: 0x%x.\n", s32Ret);
return (void*)s32Ret;
}
}
while (1) //每隔50us调用HI_MPI_RGN_SetBitMap刷新八个region
{
usleep(50);
pthread_mutex_lock(&thread_mutex);
for (item_count = 0; item_count < RGN_MAX; item_count++)
{
if (ZERO_LEVEL == Menu_Level)
text = TTF_RenderUTF8_Solid(font, strings0[item_count], forecol0[item_count]);
else if (FIRST_LEVEL == Menu_Level)
text = TTF_RenderUTF8_Solid(font, strings1[item_count], forecol1[item_count]);

else if (SECOND_LEVEL_GAMMA == Menu_Level)
text = TTF_RenderUTF8_Solid(font, strings2_gamma[item_count], forecol2_gamma[item_count]);
else
{}
temp = SDL_ConvertSurface(text, fmt, 0x00);
stBitmap[item_count].u32Width = temp->w;
stBitmap[item_count].u32Height = temp->h;
stBitmap[item_count].pData = temp->pixels;
stBitmap[item_count].enPixelFormat = PIXEL_FORMAT_RGB_1555;
s32Ret = HI_MPI_RGN_SetBitMap(item_count, &(stBitmap[item_count])); //刷新region
if (s32Ret != HI_SUCCESS)
{
printf("HI_MPI_RGN_SetBitMap failed with %#x!\n", s32Ret);
return (void*)s32Ret;
}
free(stBitmap[item_count].pData);
stBitmap[item_count].pData = NULL;
}
if ('q' == g_ch)
break;
pthread_mutex_unlock(&thread_mutex);
}
free(fmt);
fmt = NULL;
SDL_FreeSurface(text);
SDL_FreeSurface(temp);
TTF_CloseFont(font);
TTF_Quit();
return (void*)0; //退出线程前释放资源
}
在运行这个demo的时候过段时间会自动退出并报out of memory信息,如果加大usleep(5000),也就是增大刷新间隔,这个demo会坚持更长的时间才自动退出。所以基本可以确定问题是出在刷新Region的地方。大家在做海思osd的时候有没有遇到类似的问题?
