本篇记录实现一个rtsp转rtmp直播流的程序！闲言少叙，接下来置入主题。
外部调用avformat_open_input方法,内部会调用init_input/avio_open2方法,接着查找协议并且打开,另外是打开fifo。整体的avio打开流程如下: avio_open()调用avio_open2(),而avio_open2()又调用ffio_open_whitelist(),代码如下: int ffio_open_whitelist(AVIOContext **s, const char *filename, int flags, cons...
But when i set rtsp url as ffmped_url value, i am getting error below: Url: private String ffmpeg_link = "rtsp://192.168.0.35:1935/live/android"; Recorder setting (note that i have replaced format to 'mp4' Log.i(LOG_TAG, "ffmpeg_url: " + ffmpeg_link); //recorder = new FFmpeg...

ffmpeg avformat_open_input 阻塞 ffmpeg aviocontext FFmpeg数据结构分析 FFMPEG中结构体很多。最关键的结构体可以分成以下几类: 1、解协议(http,rtsp,rtmp,mms) AVIOContext,URLProtocol,URLContext主要存储视音频使用的协议的类型以及状态。URLProtocol存储输入视音频使用的封装格式。每种协议都对应一个URLProtocol结构...

* If this AVIOContext is created by avio_open2(), av_class is set and * passes the options down to protocols. * * If this AVIOContext is manually allocated, then av_class may be set by * the caller. * * warning -- this field can be NULL, be sure to not pass this AVIOContext...
Hi! When streaming rtsp to rtmp I found this exception org.bytedeco.javacv.FrameRecorder$Exception: avio_open2 error() error -5: Could not open 'null' at org.bytedeco.javacv.FFmpegFrameRecorder.startUnsafe(FFmpegFrameRecorder.java:859) a...
ret = avformat_open_input(&fmt_ctx, NULL, NULL, NULL); if (ret < 0) { fprintf(stderr, "Could not open input\n"); goto end; } ret = avformat_find_stream_info(fmt_ctx, NULL); if (ret < 0) { fprintf(stderr, "Could not find stream information\n"); goto end; ...
1.1解协议(http,rtsp,rtmp,mms) AVIOContext,URLProtocol,URLContext主要存储视音频使用的协议的类型以及状态。URLProtocol存储输入视音频使用的封装格式。每种协议都对应一个URLProtocol结构。(注意:FFMPEG中文件也被当做一种协议“file”) 1.2解封装(flv,avi,rmvb,mp4) ...
