git clone git://github.com/kolyvan/kxmovie.git
cd kxmovie
git submodule update --init
rake
二、使用kxmovie 1.把kxmovie/output文件夹下文件添加到工程 2.添加框架:MediaPlayer, CoreAudio, AudioToolbox, Accelerate, QuartzCore, OpenGLES and libz.dylib,libiconv.dylib 3.添加lib库:libkxmovie.a, libavcodec.a, libavformat.a, libavutil.a, libswscale.a, libswresample.a 4.播放视频:
ViewController *vc;
vc = [KxMovieViewController movieViewControllerWithContentPath:path parameters:nil];
[self presentViewController:vc animated:YES completion:nil];
5.具体使用参考demo工程:KxMovieExample 三、碰到的问题 播放本地视频和网络视频正常,播放网络摄像头实时监控视频流(h264)的时候出现错误:
[rtsp @ 0x906cc00] UDP timeout, retrying with TCP
[rtsp @ 0x906cc00] Nonmatching transport in server reply
[rtsp @ 0x906cc00] Could not find codec parameters for stream 0 (Video: h264): unspecified size
Consider increasing the value for the ‘analyzeduration‘ and ‘probesize‘ options
Couldn‘t find stream information
跟踪代码,错误是在avformat_find_stream_info获取流信息失败的时候的时候触发。
if(avformat_find_stream_info(pFormatCtx,NULL) < 0) {
av_log(NULL, AV_LOG_ERROR, "Couldn‘t find stream information\n");
goto initError;
}
经过几天的摸索,最终确定是网络的问题(在模拟器播放一直出错,在3G网络下能播放……
// Open video file
pFormatCtx = avformat_alloc_context();
//有三种传输方式:tcp udp_multicast udp,强制采用tcp传输
AVDictionary* options = NULL;
av_dict_set(&options, "rtsp_transport", "tcp", 0);
if(avformat_open_input(&pFormatCtx, [moviePathcStringUsingEncoding:NSASCIIStringEncoding],NULL,&options) != 0) {
av_log(NULL, AV_LOG_ERROR, "Couldn‘t open file\n");
goto initError;
}
// Retrieve stream information
if(avformat_find_stream_info(pFormatCtx,NULL) < 0) {
av_log(NULL, AV_LOG_ERROR, "Couldn‘t find stream information\n");
goto initError;
