[streaming source plugin] : Info needed

Hello All,

I need to develop a some source plugin that can generate source from a file(*.mp3 , which is not a file residing on the local machine, but instead a file mounted from some remote machine using djmount).

I thought of using "filesrc" plugin along with decodebin to play the file. it plays fine when the network condition is good but in case of Wireless i observe there is some cut in the playing for every certian interval

(,say 8 sec). Please let me know what could be the problem. your inputs are highly appreciated.

Thanks & Regards,

Satish Pattar

(for other djmount is a fuse thingy to mount a upnp share).

Satish, maybe you are needing some larger buffering after filesrc. Also why
don't you just use some httpsrc to play from the upnp share?

Re: [streaming source plugin] : Info needed

Hello Stefan,

Thanks for your very good input. I see "souphttpsrc" plugin installed in my pc . Do you think it can straightway be used as source plugin to stream UPnP media file. Also , I learnt that UPnP share uses SSDP protocol hence I am doubting whether I can use souphttpsrc or not.

Please provide your inputs.

Thanks & Regards

You can use libgupnp to handle the upnp parts. Once you got a media url, use
gstreamer to play from it (just use playbin2 and set the http url you got from
the upnp side).

Re: [streaming source plugin] : Info needed

Hello Stefan,

I don't want to use playbin2 since I see playbin2 is beffering & playing. Let me explain my set up to make you understand my problem.

I am mounting the media files residing on my phone (twonkey server is running on my phone) on to my PC using djmount client running on my pc over WiFi.

Once mount is successful , I see all the media files look like a regular file (i can do open/seek etc on the files).

For example I see the files mounted in my pc at /home/upnp/Twonkey_Mobile/Music/All_tracks/*.mp3

I don't know how to find out the URI associated with each file to provide it to souphttpsrc plugin.

One more experiment I did , I just tried fdsrc instead of filesrc by opening an upnp mp3 file & providing it's "fd" to it. This plays fine without any buffering & there are no breaks in the audio.

Do you see any limitation in making use of this plugin ?

Also with fdsrc I am able to seek forward correctly but on seek backward say for "n" sec , I am hearing no sound for "n" sec & exactly after n sec,

playback starts from the new seeked position in the stream. Is there any thing wrong I am doing in passing the seek event? or Is it the limitation of fdsrc. ?

// code snippet for seeking

void seek_handler (double displacement) // displacement is in second

{

GstFormat fmt = GST_FORMAT_TIME;

gint64 cur_pos;

gst_element_query_position (pipeline, &fmt, &cur_pos);

double new_pos_sec = cur_pos * (1.0 / GST_SECOND) + displacement;

seek (new_pos_sec * GST_SECOND);

}

void seek (gint64 new_pos)

{

if (new_pos < 0)

new_pos = 0;

gst_element_seek (pipeline, 1.0, GST_FORMAT_TIME, GST_SEEK_FLAG_FLUSH, GST_SEEK_TYPE_SET,

new_pos, GST_SEEK_TYPE_NONE, GST_CLOCK_TIME_NONE);

}

Thanks & Regards

Satish
