So Erik,

 

Are there plans to eventually merge this with master?

I just learned that VU+ are actually working on the gstreamer/driver adaptation, so it might pay off to have a little more patience.

Yes I think indeed better wait. For audio you can tell that pli's gst-1.0 mediasink works, and i'm pretty shure 100 % ok.

 

For video not I tried to use 16 for wmv1 and wmv2 ,17 for wmv3 , but audio always ok video does not play. The video could have something to to with the servicesmp3.cpp which is not 100 % yet for gst-1.0 .

Nice, so now that the dm800se works, we'll also have VU working in the near future :D

If it works for the DM800SE, doesn't that mean it should also work for all other DMM models, like the 8000, 7020HD etc.

Buffering settings for playbin are not optimal. Currently we have buffer-size set to 5MB and buffer-duration set to 5 seconds. When one of this values is reached durring buffering than buffering stops.

This means that buffer-size of 5MB is almost never filled, since buffer-duration is too low.

 

For example:

 

SD media(45min - 350MB) : ~650KB/5s
HD media(90min - 4000MB) : ~3700KB/5s

 

This causes prefill buffer mode to be almost unusable, because of incessant re-buffering, since buffer is immediately drained after reaching 100% to bigger HW buffer.

 

So either we should increase buffer duration to some reasonable limit ~40s or turn it off, meaning that buffering will always stop after it reaches 5MB, which significantnly reduces re-buffering.

 

 

I did tests on et6500 with gst1.0:

 

There is no bottleneck on source's side

 

buffer-duration 5s:

- default buffer mode - 410MB/50min(SD)  sometimes stuttering

- default buffer mode - 900MB/50min(HD) stuttering

- prefill buffer mode - 410MB/50min(SD)  endless re-buffering

- prefill buffer mode - 900MB/50min(HD) endless re-buffering

 

buffer-duration turned off:

- default buffer mode - 410MB/50min(SD)  seamless playback

- default buffer mode - 900MB/50min(HD) stuttering

- prefill buffer mode - 410MB/50min(SD)  seamless playback

- prefill buffer mode - 900MB/50min(HD) one time re-buffering, then seamless playback

 

So it improves buffering performance, mainly in prefill buffer mode.

Ok here now adapted vuplus gst-1 branch patch. I added the gstreamer1.0-plugin-dvbmediasink.patch

 

Now on vuduo2 WMV plays with WMV3 media. video ok audio ok.

 

Here the renewed gst-1.0 git patch.

 

I also added separately the gstreamer1.0-plugin patch voor vuplus.

 

The only thing is that playing wav files from out of enigma2 does cause enigma2 crash after the song is played. unrecoverable except trough telanet by killing enigma2. The reason is a segfault.

 

When playing wav file out of telnet console (after init 5 enigma2 stopped) . It plays but we have warning concerning buffers and mutex. Which is the cause of enigma crash when playing out off enigma2.

root@vuduo2:/media/VIDAUD# gst-launch-1.0 playbin uri=file:///media/VIDAUD/Front_Right.wav

maybe the patch from mx3L could solve the crash out off enigma2 , but the reason of error is still there.

I'm still trying to find a solution to the wav file problem. But no luck.

 

What I well found out is that for wav file its tries to use

WARNING: from element /GstPlayBin:playbin0/GstPlaySink:playsink/GstBin:abin/GstAutoAudioSink:audiosink/GstDVBAudioSink:audiosink-actual-sink-dvbaudio

instead off

/GstPlayBin:playbin0/GstPlaySink:playsink/GstBin:abin/GstDVBAudioSink:dvbaudiosink0.GstPad:sink:

looks like it is cause there is no codec and it's uncompressed.

 

tag wav file

/GstPlayBin:playbin0/GstInputSelector:inputselector0.GstSelectorPad:sink_0: tags = "taglist\,\ audio-codec\=\(string\)\"Uncompressed\\\ 16-bit\\\ PCM\\\ audio\"\;"

and it plays with (it really plays but with warning )

/GstPlayBin:playbin0/GstPlaySink:playsink/GstBin:abin/GstAutoAudioSink:audiosink/GstDVBAudioSink:audiosink-actual-sink-dvbaudio.GstPad:sink: caps = "audio/x-raw\,\ format\=\(string\)S16LE\,\ layout\=\(string\)interleaved\,\ channels\=\(int\)1\,\ rate\=\(int\)48000"

 When using gst-launch-1.0 playbin uri=file///xxxxx  (after init 5) play ok but error's are :

root@vuduo2:/media/VIDAUD# gst-launch-1.0 playbin uri=file:///media/VIDAUD/Front_Right.wav

When playing out off enigma. It cause unrecoverable enigma2 crash (after the audio is played ) the audio plays that well.

 

I really can't find a solution . And problem is only for wav files . All other audio runs fine.

Would be nice if someone who nows more about gst-1.0 does have ideas to solve this wav isue. Since this issue is a blocker to any further use off gst-1.0. If any media or plugin or broadcast media such as out gemist or hbbtv has a wav format somewhere enigma2 will crash unrecoverable.

Is this only vu+ related? If not can you upload your problematic wav file and post direct link here? I will test it on xtrend.

No I do not think it's related to vu+ . Ok I test on vuplus.

 

Same file does work perfect on vu+ when using gst-0.10 (with the schwerchcraft sink from dvb elite , but also work's perfect with gst-0.10 using pli's dvb mediasink on vuduo2).

 

links  I put same file once the original .wav (it's just an audio speaker test wav file very short). Once the converted file into flac format. And one a reconvert off the flac file back to wav.

 

http://users.telenet...nsp/Front_Right.wav original play with error

 

plays perfect

 

http://users.telenet...ront_Right2.wav plays with the error .

Posted 12 March 2015 - 12:31

It seems that gst-1.4.5 uses the autoaudiosink element when a stream type is obtained with autodetect (which on it is needed for wav files). Somehow there must be a way to disable the autoaudiosink element into playbin . If that element is disabled most probably problems will be solved. Since it then should use the defined sink. which is dvbaudiosink0 .

.

 

But how ? thats the question.

 

p.s. when playing al other encoded formats autodetect is not used. That's why we have the correct bin for those formats.

Yes what's the log when You play out off enigma.

 

It's all comming from gstreamer 10 self. They there fore add a work around , if there is no new segment they create one whit start position 0 . And or won dvbmediasink does not have the keps using the old. Therefore it continu's playing while there is no audio to play anymore which result's in a usseles lock command but followed by an unlock and there it's going wrong.
