本文对应的ijkplayer版本为: k0.7.9
ijkplayer播放器在拉到第一条数据流的时候如果没有解出音频包，ijkplayer 就一直没有声音了！
正常能播放时 ijkplayer 解到的首包 包含音频stream 和视频stream
ijkplayer播放器的read_thread数据接受线程在处理音频的时候如果首个数据包没有发现audio stream 以后就不会有音频数据了 这是个bug 解决方法如下:
pkt->flags = 0;
ret = av_read_frame(ic, pkt);
if (is->audio_stream >= 0) {
//之前已经发现音频信息
}else{
if (!ffp->audio_disable){
av_log(NULL, AV_LOG_INFO, "is->audio_stream = %d\n", is->audio_stream);
#if 1
int audio_stream_idx = av_find_best_stream(ic, AVMEDIA_TYPE_AUDIO,
st_index[AVMEDIA_TYPE_AUDIO],
st_index[AVMEDIA_TYPE_VIDEO],
NULL, 0);
if (audio_stream_idx >= 0){
//之前没有发现音频信息
av_log(NULL, AV_LOG_WARNING, "重要信息发现 -> 音频流\n");
refind_audio_stream(ffp, ic, audio_stream_idx);
}
av_log(NULL, AV_LOG_INFO, "is->audio_stream = %d\n", is->audio_stream);
#endif
}
}
//static int refind audio stream
static int refind_audio_stream(FFPlayer *ffp, AVFormatContext *ic, int stream_index) {
/* open the streams */
if (stream_index >= 0) {
#warning 测试代码
//打开音频流
stream_component_open(ffp, stream_index);
av_log(NULL, AV_LOG_INFO, "打开音频流stream\n");
}
ijkmeta_set_avformat_context_l(ffp->meta, ic);
if (stream_index >= 0){
ijkmeta_set_int64_l(ffp->meta, IJKM_KEY_AUDIO_STREAM, stream_index);
av_log(NULL, AV_LOG_INFO, "音频原始数据初始化\n");
}
return 0;
} //直接用下面的代码替换ff_play.c 文件就可以了
