thanks. It was late and whne i previously opened the file i didn't realise there was a folder inside...

anyway, here is a "hack" for the audiosink to give you sound on those streams.
BUT, i have no idea about side effects at this stage. I've changed a particular catch all routine when there is no codec data to construct the aac header from.
so please test this with other streams to see if you are loosing audio where you had audio so far.
Also test this with movie files with aac audio.

meanwhile, i'll have a think about the not smooth video..

enjoy,

Hi dazulrich.
Job well done, thank you very much!
The problem with the sound is successfully solved by you, congratulations.
I checked the video files to AAC, everything is in order.
I did not reveal new problems continue to further testing.

Hi Ingo. thanks. Just a user helping other users...
Now re the not smooth streams.
Can you use livestreamer to capture and save the stream to disk and then play it using media player? I'd like to find out whether the problem relates to streaming or the h264 profile used by those streams.
I've captured streams on my PC by using livestreamer http://docs.livestreamer.io cmd line. for eaxmple

[path.to.livestreamer\]livestreamer hls://"[url of your m3u8]" best -o savedstream.ts

more cli options are described here http://docs.livestreamer.io/cli.html (like best/worst for stream quality or httpstream://, hlsvariant:// etc for other streaming protocols)
I believe you can install livestreamer on the box via cmd line from the feed as well and do the capture there.

If you could test the stored files with the old and the new videosink and let me know which combination plays smooth and which is not smooth. That will help me look for changes that could have affected the playback.

Hi dazulrich, I am pleased to further testing.

I gave the command:

Code:

"C:\Program Files\Livestreamer\livestreamer.exe" hls://"http://s2.kodik.cc/content/stream/films/the.5th.wave.2016.720p.webdl.rus.ukr.eng/hls/720/index.m3u8" best -o savedstream.ts

MeiaInfo savedstream.ts:

Spoiler:

In mediaplaer, regardless of the version libgstdvbvideosink.so (16027,16117) savedstream.ts smooth playback (no problem).

ps
When playing .ts mediasink files also needed, because the video processing in this case, gstreamer is not used, or am I mistaken?

**dazulrich** · 16.11.2016

thanks Ingo. you are probably right. we may need to recencode the MPEG-TS format to MP4 format for this to be valid test.
you could try remuxing it like this using ffmpeg

ffmpeg -i input.ts -acodec copy -vcodec copy out.mp4

The reason I'm asking if you can do it, is my ME may not stutter the same way, so I can't really test for improvements .
But what I'll do is revert 2 changes made and post 3 videosink files (revert 1, revert 2, revert both) to test the streaming.

Introduced team:

Code:

ffmpeg -i savedstream.ts -acodec copy -vcodec copy savedstream.mp4

Gives an error message:

[NULL @ 0x487a50] Unable to find a suitable output format for 'savedstream.mp4'
savedstream.mp4: Invalid argument

Full log file attach.

thanks for trying.
it might be stupid suggestion, but googling for answers on the error i noticed that the order of "-acodec copy -vcodec copy" is the other way round "-vcodec copy -acodec copy".
also saw that in ffmpeg docs.

An empty stream specifier matches all streams. For example, -codec copy or -codec: copy would copy all the streams without reencoding.

so maybe try

ffmpeg -i savedstream.ts -codec copy savedstream.mp4

**ingo** · 16.11.2016

Thanks, but is unchanged:

[NULL @ 0x487a40] Unable to find a suitable output format for 'savedstream.mp4'
savedstream.mp4: Invalid argument

Maybe it depends on the version of ffmpeg?

@dazulrich
Convert ts to mp4 using https://convertio.co/ru/ts-mp4 service.
MeiaInfo savedstream.mp4:

Spoiler:

In mediaplaer, regardless of the version libgstdvbvideosink.so (16027,16117) savedstream.mp4 smooth playback (no problem).

**dazulrich** · 16.11.2016

Thanks for testing. Not really what I had expected. Unless the service reencoded instead of stream copy.
There were some changes that had references to streaming. Will revert those and provide test sink.
Btw. The current image from today should have the latest mediasink with the audio fix.
