这里有一个蟒蛇新手.我想我的网站支持英文和中文.所以我只是按照django书,第19章国际化.但它似乎对我不起作用,字符串我希望显示为中文,仍然是英文.我的代码和设置如下.
[settings.py]
LANGUAGE_CODE = 'zh-cn'
USE_I18N = True
USE_L10N = True
LANGUAGES = (
('en', 'English'),
('zh-cn', 'Chinese')
)
TEMPLATE_CONTEXT_PROCESSORS = {
'django.core.context_processors.i18n',
}
MIDDLEWARE_CLASSES = (
'django.middleware.locale.LocaleMiddleware',
'django.middleware.common.CommonMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
)
在我的app views.py中,我强制在索引中将语言代码设置为'zh-cn'
def index( request ):
response= render_to_response( 'index.htm' )
response.set_cookie('django_language','zh-cn')
return response
那么我希望在index.htm之后加载的另一个页面会显示一个中文字符串.
另一页由upload.html呈现
{% load i18n %}
<html>
<head>
{% block head %}
{% endblock %}
</head>
<body>
{% block body %}
<h1>{% trans 'Upload Demo' %}</h1>
{% endblock %}
</body>
</html>
那之后,我做到了
django-admin.py …尝试使用sws_scale将YUV420p转换为RGB24时，图像失真。
码：
ret = avcodec_decode_video2(video_dec_ctx, frame, got_frame, &pkt);
if (ret < 0) {
fprintf(stderr, "Error decoding video frame\n");
return ret;
}
if (*got_frame)
{
printf("video_frame%s n:%d coded_n:%d pts:%s\n",
cached ? "(cached)" : "",
video_frame_count++, frame->coded_picture_number,
"#"/*av_ts2timestr(frame->pts, &video_dec_ctx->time_base)*/);
/* copy decoded frame to destination buffer:
* this is required since rawvideo expects non aligned data */
av_image_copy(video_dst_data, video_dst_linesize,
(const uint8_t **)(frame->data), frame->linesize,
video_dec_ctx->pix_fmt, video_dec_ctx->width, video_dec_ctx->height);
/* write to rawvideo file */
fwrite(video_dst_data[0], 1, video_dst_bufsize, video_dst_file);
AVPicture pic;
avpicture_alloc( &pic, AV_PIX_FMT_RGB24, frame->width, …
