To see stats,audio & video during streaming from rc interfac

[anoopvuppala]

Hej,
I want to view the statistics in a console for that i am using "vlc --intf rc" and another window opens,there I am using stats but a reply like this appears "stats:returned (no error)"----------1)what i have to do now to view the statistics in console.

2) when i am using this command "vlc filename input_stream --sout "#std{access=udp,mux=ts,dst=194.47.147.138:1234}:display{audio,video,delay=5ms}" i am able to stream and can see video on receiving side but my problem is i am not able to see them on streaming side. so can anyone tell me what are the modifications to be done to the command to see the audio and video on streaming side

3) when i am using this command vlc --intf rc another window opens and there i have to type "stats" for viewing the statistics but is there any direct command to see the statistics directly in command line.
thanks and regards,
anoop vuppala

2. It would help us if you told how you try to open the video in client.

[anoopvuppala]

i used this command "vlc udp://@:1234" to view the video from client side but here also i am not able to view the statistics by using stats command --intf rc interface.

please guide me what i have to add to the command to view the statistics on both side

one more thing yesterday i used this command "vlc filename input_stream "#std{access=udp,mux=ts,dst=194.47.147.138:1234}" --intf rc and the video opens with a title like this "vlc (hardware YUV overlay DirectX output)" and also an rc interface open where i gave command stats and i got everything over there but i am not able to transmit i mean the video is not opened in client side.

please help me,
thanks and regards,

Is the 194.47.147.138 address of client?

[anoopvuppala]

hey,
-> few of my problems were solved i can see audio and video on client with statistics using a modified command
client side:vlc udp://@:1234 --intf rc
-> when coming to streaming side i can see only statistics of input bitrate but no audio and video and the command is
streaming side: vlc filename,location and format --sout "#std{access=udp,mux=ts,dst=ip address of client:portnumber}" --intf rc
-> when i use this command i can view the statistics of all the things but its not receiving on client side.
streaming side: vlc filename,location and format --sout-all "#std{access=udp,mux=ts,dst=ip address of client:portnumber}" --intf rc
the problem left was
-> what are the modifications to be done to the command to get audio and video on streaming side
-> i want to store the statistics obtained in "--intf rc" interfaceand how can i do that

[VLC_help]

I haven't used the statistics option so I cannot help you with those.

[anoopvuppala]

I haven't used the statistics option so I cannot help you with those.

ok then, but can you help me whats the problem that why i am not able to see audio and video on streaming side when i use this command "vlc filename input_stream "#std{access=udp,mux=ts,dst=194.47.147.138:1234} --intf rc" please still what i had to add or remove to this command.
thanks and regards,
anoop vuppala.

[anoopvuppala]

filename input_stream

you have two inputs you want to play?

i didn't got you and my problem was solved.

[anoopvuppala]

filename input_stream

you have two inputs you want to play?

i didn't got you and my problem was solved.

i used transcode function along with std in command line to see audio and video on streaming side
-> one more thing left was that is there any where in the source code to put a function so that it will call some functions every minute so that i can print the statistics to a file.

thanks and regards,

You can modify statistics writing function and add new thread there that uses mwait.
http://git.videolan.org/?p=vlc.git;a=tr ... misc/stats it might be that, or not.

Code: Select all

if (UPDATE == null)

?

Code: Select all

if (UPDATE == null)

?

update is a void function so it will not return anything so i want to check it update is null then execute the entire steps if not so i will remove null and i will call update with pointer
just like here "update( input_item_t *p_item )"
and i will declare ifdef function in info_pannels.hpp with a time_t mytime.

[VLC_help]

UPDATE is a macro, and it takes 3 parameters.

it showing me an error saying that "File and fp were not declared in this scope"
so where should i have to declare them
please tell me

[VLC_help]

#include at the beginning should make them OK.

i assigned the function in two different ways: the above is output for first method.
Method1:
{
FILE *fp = fopen ("/media/9C1CC0671CC03DD0/1.txt","a");
float reme = (float)(p_item->p_stats->i_read_bytes)/1024;
float stat[] = {reme};
fwrite (stat,sizeof(float),sizeof(stat),fp);
fclose(fp);
}
Method2:
FILE *fp = fopen ("/media/9C1CC0671CC03DD0/1.txt","a");
float reme = (p_item->p_stats->i_read_bytes);
fprintf(fp,"%f",&reme);
i think i am at the end i am working very hard for a simple things but even though i am not able to do.
guide me please
thanks and regards,
anoop vuppala.

IIRC fprintf works with variables, so something like

Code: Select all

float reme = (float)(p_item->p_stats->i_read_bytes); fprintf(fp,"%f",reme);

might work.

You could create a plugin that you could just add to other VLC installations, if you don't want to share your whole VLC setup to other computers.

i want to share the whole vlc i mean example like ".exe" file. which parameter stores the necessary information of buffer (empty, full) and where it is located in source code
thanks and regards,
