Hello,

 

This is patch for ffmpeg libs. So, there is need to re-compile libs with this patch.

 

Regards,

SSS

[samsamsam]

If you want to try:

here are compiled libs with patch (mips32el, hard fpu, openssl 1.0.2):

 

http://iptvplayer.pl...0.2_dash.tar.gz

SSS

Many thanks SSS,

using atv 5.3 I've just transferred the files over and getting this error;

 

 PlayerApp::stderrAvail: exteplayer3: relocation error: /usr/lib/libavformat.so.57: symbol SSL_library_init, version OPENSSL_1.0.0 not defined in file libssl.so.1.0.0 with link time reference

 

St.O

[samsamsam]

Hmmm, so it seems that I compiled libs with OpenSSL 1.0.0 not 1.0.2

I will re-compile in free time with 1.0.2, but generally I will not compile libs for each E2 distribution.

 

Regards

[ian1095]

Ah ok

 

That explains why I too when I tested had the same problem as posted above.

 

Thanks SSS

@ian1095

 

I re-compiled ffmpeg libs for you:

 

http://iptvplayer.pl...0.2_dash.tar.gz

[ian1095]

Unfortunately not working through Serviceapp set to Exteplayer3

 

No errors though, it just doesnt work.

 

But heres the debug anyway.

I forgot to say.

 

The above is using the Mastag image based on Pli 4.0 with Serviceapp from around the end of October 2016 I dont know if having this older version of Serviceapp makes a difference or not ?

@ian1095

 

I do not know. I am not using service app.

 

This mpd can use different profile.

 

Please try to execute following command:

 

ffmpeg -i "http://vod-dash-uk-live.akamaized.net/usp/auth/vod/piff_abr_full_hd/ee96af-b08d4341/vf_b08d4341_7b4660af-5853-4419-a464-ebe27fed16db.ism/pc_hd_abr_v2_dash_master.mpd?__gda__=1485873400_506eef2986a9d67a01404d9e9fe05ba6" -logleve debug

 

and provide output.

 

Please also try to play stream which I know that works to make sure that proper ffmpeg libs are used.

Your known working stream gives this, but other than BBC iplayer used in my first log ive no other way of testing dash at the moment. Its for BBC iplayer that I'm most interested in this new mod.

Ok further testing has shown that you known working stream does indeed play.

 

Its just streams from BBC iplayer that do not.

 

(  I wish someone would set the forum to allow a slightly longer time period for members to edit posts )

@ian1095

 

In BBC iplayer there is two problems:

1. not recognized mpeg dash profile 

2. not playing h264 codec, probably due to AVC3 format

 

First one is very easy to fix (there is need to small change in dash demux patch - I will prepare it).

Second one (AVC3 h264 variant) is hard one. Hardware decoder is not able to play h264 AVC3. 

There is probably need to change PES formater to allow to play such stream.

 

I will fix first problem, so you will be able to play this stream but you will have only sound due to second problem.

At now I do not know how to fix second problem. I must do more investigation.

 

Regards,

SSS

[ian1095]

Thanks SSS

 

That's how it is currently when using Serviceapp set to use Mediaplayer and Gstreamer without your new patched libs , only the audio is played, there is no picture displayed.

 

Bummer eh ? I hope you can find a resolution to this.

 

Ian.

Edited by ian1095, 31 January 2017 - 11:36.

[samsamsam]

Good news

 

I was able to play stream

There is need to make some changes in PES formater for H264, but good new that it is possibile.

I must clear my code and then I will provide you new version for test.

 

Regards,

SSS 

[ian1095]

Awesome news SSS

 

It will be great to have the 1080 streams from BBCiplayer, however I think even though the json says they are 1080, they are in actual fact 720.

 

None the less, getting DASH to stream on our boxes is a massive step forward, because I'm sure in the future, they will offer true 1080

 

Ian.

Edited by ian1095, 31 January 2017 - 21:46.

[samsamsam]

@ian1095

 

Here you can download test binaries:

http://iptvplayer.pl/temp/dash_test/

 

You must update both exteplayer3 binary and ffmpeg libs,

 

 

My patch for ffmpeg adding MPEG-DASH not hande auto resolution/quality/bitrate management.

There is need to select one quality at start and this quality is used. If not selected the first one from the list is used.

 

So, there will be also need to change service app to handle this behavior similar as it is for HLS.

 

So, for example to play best quality from cmd line:

 exteplayer3 "http://a.files.bbci.co.uk/media/live/manifesto/audio_video/simulcast/dash/uk/dash_pc/llnw/bbc_one_london.mpd" -0 3 -1 0

 

Where:

[-0 idx] video MPEG-DASH representation index

[-1 idx] audio MPEG-DASH representation index

[ian1095]

Yep that's working SSS nice one.

 

BBCIplayer is now streaming using DASH.

 

However like you say there is a quality issue and its streaming the lowest res, so the plugin is going to have to be adapted not to use auto res and/or auto bitrate, but that can be looked at tomorrow.

 

For now though I can report its working.

 

Many thanks.

 

Ian.

Edited by ian1095, 31 January 2017 - 22:46.

[samsamsam]

This is why I suggest you to test from command line.

From command line you will be able to choose quality as described.

SSS
