[ANNOUNCE] iStreamdev-1.0.1 - stream vdr & media files to your Iphone

Sorry my fault

You have to set the permissions of "istreamdev" for the user www-data.

Do this in /var/www :

chown -R www-data:www-data istreamdev

I tested it with permissions set to root, then I get:

vdr-ng-3:/var/www/istreamdev# ./istream.sh http://localhost:3000/TS/11 512k 64k 1 480x320 ./ 3 /usr/bin/ffmpeg

Same result as you. So the whole path must be set to www-data.
And if you want to test istream.sh from the comandline you must switch to user www-data.

Hope it will work now.

I did it before and again. Same result:

root@ubuntu:/var/www# cd istreamdev/

The user www-data does exist and I deleted from "/etc/at.deny", any other ideas. Do you need a log?

Maybe you can post your syslog showing what happend when you start istream.sh.
I saw that you start istream.sh as root. You have to switch to user www-data.

Which version of istreamdev is this?
It worked for me starting with version 0.3.5 (any other versions prior this didn't work on my VDR).

Roupi

PS: try again on the iPhone, maybe it already works. On the iphone you have to activate plug-ins (in Settings -> Safari). Otherwise it won't work.

It's version 0.3.6. Even as an user of group www-data it doesn't work:

yavdr@ubuntu:/var/www/istreamdev$ ./istream.sh http://localhost:3000/TS/11 512k 64k 1 480x320 ./ 3 /usr/bin/ffmpegyavdr@ubuntu:/var/www/istreamdev$ [mpegts @ 0xa9c6150]max_analyze_duration reached

I can start a stream on the iPhone but theres just the Quicktime symbol and a "loading" but no TV

but there are Streams in the ram folder:

root@ubuntu:/var/www/istreamdev# ls /var/www/istreamdev/ram
dummy.txt  stream-65.ts  stream-66.ts  stream-67.ts  stream-68.ts  streaminfo  stream.m3u8

syslog and messages doesn't show anything about istreamdev or istream.sh. just this:

Feb 21 17:16:32 ubuntu vdr: [3936] Streamdev: Accepted new client (HTTP) 127.0.0.1:40277
Feb 21 17:16:32 ubuntu vdr: [4126] streamdev-writer thread started (pid=2084, tid=4126)
Feb 21 17:16:32 ubuntu vdr: [4127] streamdev-livestreaming thread started (pid=2084, tid=4127)

Hmmm, nicht so einfach was

OK, let's find it out.

Have you try if the segmenter is working?

Try to call segmenter from the comandline without any path, just "segmenter"
You should get this:

Usage: segmenter <input MPEG-TS file> <segment duration in seconds> <output MPEG-TS file prefix> <output m3u8 index file> <http prefix> [<segment window size>]

Then start streaming from iPhone, check if there are files generated in /var/www/istreamdev/ram. The files called stream-1.ts, stream-2.ts and so on.

Can you play this files with vlc on your PC?

Your syslog looks good, streamdev seems to work.

Feb 21 17:16:32 ubuntu vdr: [3936] Streamdev: Accepted new client (HTTP) 127.0.0.1:40277
Feb 21 17:16:32 ubuntu vdr: [4126] streamdev-writer thread started (pid=2084, tid=4126)
Feb 21 17:16:32 ubuntu vdr: [4127] streamdev-livestreaming thread started (pid=2084, tid=4127)

Have you try the other bandwiths like Edge or 3G?

Roupi

segmenter works! I can play these files with vlc, but there are just single pictures no video and time of the files is 00:00!?

just use edge.

Jetzt aber wirklich auf deutsch: Es wird kompliziert. Das iPhone kann keinen Stream "alleine" starten. Erst nachdem ich auf der shell

./istream.sh http://localhost:3000/TS/11 512k 64k 1 480x320 ./ 3 /usr/bin/ffmpeg

eingegeben habe, kann das iPhone einen Stream vermeintlich starten, es kommt halt nur der schwarze Hintergrund mit Quicktime-Symbol.
Und die jeweiligen TS dateien in "ram" sind von dem über die shell gestarteten Kanal.
Eyeyey. Ich häng mal meine config.php ran.

.. hmm
in your config.php, the path to ffmpeg is /ffmpeg.
Is this correct ? If not, maybe it's worth a try to point this to your correct binary in /usr/bin/ffmpeg ...

rob.

Nur mal ein paar Vermutungen:

- Welche iPhone FW? Ich bin auf 3.1.3, 3.1 geht aber auch.
- Sauber gestartet? D.h. alle alten ffmpeg Tasks am VDR gekillt?
- am iPhone alles aktiviert (JavaScript, Plug-Ins)?
- iPhone mal rebootet?
- Wie funktioniert das bei Dir? Wenn Du einen Kanal wählst und dann auf Edge gehst kommt oben das Senderlogo mit nem Stoppschild überlagert. Das verwandelt sich nach ner Weile in ein Play-Symbol welches Du dann drücken kannst?

Ufffargh... It works! Sometimes it's so easy. It was from an "older" version I compiled, i didn't updated. ARRRGH.

Thank You Rob and roupi

Somebody101 you are the king!!!

Thanks for help!

hi *

anybody try to look over 3g or edge?

if i look over these options the iphone download the next segment and play it, after reaching the end of this segment the iphone make a pause and dowload the next segment if download completed it play til end than it download the next .. and so on ..

you can't enjoy looking tv over 3g or edge ..

is it possible to say the iphone that it download the next segment in background ..

hmmm over wifi the download is so fast that there is no problem ..

greetings mentox ..

i have also try with only 64k on 3d .. same effect

hmm .. any idea to debug?

mentox

I checked it to, and I have the same behavior. It plays a bit of a segment, stops and continues with the next segment.
I also set the bitrate to 48/12 K
I think my upstream is still to low for this. I will try even lower bitrattes, but than It's no fun to watch anymore.

Same problem here.
I tried it using EDGE setting over the German T-Mobile 3G network (HSDPA enabled), the streaming stops on every single stream-* file.
When I press "pause" and then "play" the stream starts again.
Sometimes it stops completely an I have to start over again from the beginning.
Also same behavior using 3G setting.

Today I will try it over the Vodafone network.

When I increase the value of SEGDUR from 10 to 20 in istream.sh, then the stream plays for exactly 20s before it stops.
So I think it has'nt to do with the 3G network speed but with the file segmentation.
Every time a new stream file is requested, the 3G network needs to much time to deliver it to the iPhone.

Can anybody explain this behavior?

Hi all,

I can not confirm that behaviour in my setup.
I just made a test, sitting here in my office in Frankfurt City and streamed SAT.1 from my server at home over 3G Network using the Edge-Profile in istreamdev. I was also connected (parallel) over my netbook (with another 3G connection) to my vdr-server to watch the behaviour on the server, especially the /ram-directory, over a terminal.

Everything works flawlessly ... the stream came without any interruption!
In the /ram-directory I saw, that over 200 Segments were generated...

After watching a while, I went out of my office, more inward the building, where the 3G-connection isn't as good as in my office room ... and the stream stops immediately ... after loading a while, it plays again but stops after about 30 seconds again ...

So I think, it maybe has something to do with the "connection-quality" (and maybe also the upstream, you have at home (1 Mbit for me)).

I use istreamdev 0.3.6.1.

so long
rob.

Maybe the following can be the the problem when streaming over mobile networks:

Using WiFI:
When the iPhone plays a stream, for example stream-3.ts, in /ram there are the following stream files: stream-2.ts, stream-3.ts and stream-4.ts.

Using EDGE/3G:
When the iPhone plays a stream, for example stream-3.ts, in /ram there are the following stream files: stream-6.ts, stream-7.ts and stream-8.ts. The stream files 2, 3, 4 and 5 are already deleted. Now the streaming on iPhone stopps because the next file number 4 is missing.

I've tested this several times with the same result. There are always only 3 stream files left in /ram. I'd remember that in istreamdev version 0.3.3 all the stream files still exists in /ram until the stream were stopped.

Just for information: my VDR is connected to the internet via T-Home VDSL-50 with an upload of round about 10 Mbit/s.

i only have 3 stream.ts at one moment ..

tested over wifi, 3g and edge

and i think if the iphone is ready to play the next segment is already deleted on the server ..
is is possible to hold more than 3 segments?

hi mentox,

as far as I know, the amount of segments can be controlled by the "segment window size" - option of segmenter.

In istream.sh, segmenter is called this way:

segmenter - $SEGDUR $PREFIX $PREFIX.m3u8 $HTTP_PATH $SEGWIN &

default of $SEGWIN is (as far as I know) 2
(two files ready to stream, while the third one will be written - so you should see three files)

You can change this in istream.sh to e.g. this:

segmenter - $SEGDUR $PREFIX $PREFIX.m3u8 $HTTP_PATH 5 &

Then you will always have 5 files in /ram to stream (while the sixth one will be written)

give it a try...
