Hello,
I am facing issue in opening the live encoded h264 stream of 8MP resolution
over tcp server in Qt Application. To open the stream in ffplay, I give
following command in terminal and it is able to play it:
ffplay -f h264 -codec:v h264 -probesize 32M <tcp://ipaddress:port>
But when I try to open the stream in Qt Application, avformat_open_input()
gives error Invalid data found while processing input.
Below is the code I am using in Qt Application
av_register_all();
avcodec_register_all();
avformat_network_init();
AVFormatContext *refrenceFormatCtx = NULL;
SwsContext *img_convert_ctx;
AVIOContext *avio_ctx = NULL;
int video_stream_index = 0;
AVCodecContext* codec_ctx = NULL;
AVSampleFormat *fmt = NULL;
char errorsdef[100];
AVDictionary *options = NULL;
av_dict_set(&options, "video_size","3264x2448",0);
av_dict_set(&options,"pixel_format","yuv420p",0);
av_dict_set(&options, "f", "h264", 0);
av_dict_set(&options, "codec:v", "h264", 0);
av_dict_set(&options, "codec:a", "aac", 0);
av_dict_set(&options, "probesize", "32M", 0);
int err = avformat_open_input(&refrenceFormatCtx,"tcp://<ipaddress:port>",
NULL, &options);
av_strerror(err,errorsdef,100);
qDebug() << "OPening Stream error: "<< err << " "<< errorsdef;
if(err<0)
{
abort();
}
av_dict_free(&options);
Is the path to set the options in avformat_open_input is correct?
Is the parameters set by me, are correct?
If any help, it will be grateful to me.
Thanks & Regards,
Niraj Gandha
