Hi,
Well.. guess i found the problem (at least it solved my problem)..
I was missing the call for this function: av_find_stream_info(pFormatCtx)
So inserting it after the av_open_input_file, it shows all the info
for the video file..
My code is like this now:
AVFormatContext *pFormatCtx;
for(int j=0; j < listaDeVideos.size(); j++){
// Open video file
if(av_open_input_file(&pFormatCtx, ((QString)
listaDeVideos.at(j)).toLocal8Bit(), NULL, 0, NULL)!=0)
qDebug()<< "Couldn't open file";
int i;
//get the stream
if(av_find_stream_info(pFormatCtx)<0) //Here I get some
errors like: max_analyze_duration_reached
{
qDebug() << "cant initialize the Stream";
}
dump_format(pFormatCtx, 0, ((QString)
listaDeVideos.at(j)).toLocal8Bit(), 0);
// Find the first video stream
int videoStream=-1;
for(i=0; i<pFormatCtx->nb_streams; i++)
if(pFormatCtx->streams[i]->codec->codec_type==CODEC_TYPE_VIDEO) {
videoStream=i;
break;
}
if(videoStream==-1)
qDebug() << "Didn't find a video stream";
else
qDebug() << pFormatCtx->streams[videoStream]->duration;
Thanks for the help..
