ffmpeg自身写了一个的支持rtmp协议的代码,与rtmp对应的AVInputFormat为:
AVInputFormat ff_flv_demuxer = {
.name = "flv",
.long_name = NULL_IF_CONFIG_SMALL("FLV (Flash Video)"),
.priv_data_size = sizeof(FLVContext),
.read_probe = flv_probe,
.read_header = flv_read_header,
.read_packet = flv_read_packet,
.read_seek = flv_read_seek,
.read_close = flv_read_close,
.extensions = "flv",
.priv_class = &flv_class,
};
在文件libavformat/flvdec.c中
对应的URLProtocol为:
#define RTMP_PROTOCOL(flavor) \
static const AVClass flavor##_class = { \
.class_name = #flavor, \
.item_name = av_default_item_name, \
.option = rtmp_options, \
.version = LIBAVUTIL_VERSION_INT, \
}; \
\
const URLProtocol ff_##flavor##_protocol = { \
.name = #flavor, \
.url_open = rtmp_open, \
.url_read = rtmp_read, \
.url_read_seek = rtmp_seek, \
.url_read_pause = rtmp_pause, \
.url_write = rtmp_write, \
.url_close = rtmp_close, \
.priv_data_size = sizeof(RTMPContext), \
.flags = URL_PROTOCOL_FLAG_NETWORK, \
.priv_data_class= &flavor##_class, \
};
RTMP_PROTOCOL(rtmp)
RTMP_PROTOCOL(rtmpe)
RTMP_PROTOCOL(rtmps)
RTMP_PROTOCOL(rtmpt)
RTMP_PROTOCOL(rtmpte)
RTMP_PROTOCOL(rtmpts)
