@samsamsam

As far as I know we are not using synchronization against clock, since in dvbmediasink it's turned off, so synchronization is done only by drivers.

 

How is gstreamer1.0 behaving unstable for you?

 

I was using eplayer3 on ipbox55hd, but it was some time ago. Negative thing I remember was that sometimes there were spinners on loading streams or seeking in them. It looked like that these operations were running within main thread, so gstreamer experience looked smoother, otherwise there weren't problems.

 

Can you provide link to latest eplayer3 and servicemp3 for eplayer3 sources?

 

Thanks

 

You compare very old STB ipbox55hd with VU+? Do you know why you have spinner? Because there was software decoding of AAC enableded.

Why? Due to problem with drivers. Sometimes after inserting AAC PES the drivers stuck the same problem exists with gstreamer. As workaround in eplayer3 the software decoding of AAC was enabled.

 

The clue is to make player based on ffmpeg. It not need to be libeplayer3. 

I'm not going to convince anyone here. If you really think that gstreamer 1.X is stable OK keep going

But, before this please try to play FLV file at lease for 3 hours and check how many memory is taken by E2 process. Thats all

I'm not comparing ipbox55hd with vu+. I was comparing ipbox55hd with eplayer3 with ipbox55hd with gstreamer0.10. In my experience It was smoother with gstreamer0.10 when dealing with streams, but things probably changed since then..

[betacentauri]

fast rewind back does not work...... yet.

 

Why the yet ? Well the current way off work with : GST_SEEK_FLAG_SKIP

Will be deprecated. However the change is since gst 1.6 that's what they say in gstreamer manual.

The we will be able to use seekflags.

GST_SEEK_FLAG_TRICKMODE | GST_SEEK_FLAG_TRICKMODE_NO_AUDIO

 

This should make it possible to do fast forward with up to x32 for all audio. And maybe even fast rewind will work then.

 

extract gstreamer manual:

 

http://gstreamer.fre...ml#GstSeekFlags

 

I think it will never work. Not without driver (and DVB API) changes.

Look at these slides:

https://coaxion.net/...2014/slides.pdf

 

Page 13 shows the data ABCDEF...WXY. For reverse playback the demuxer have to read the GOPs from right to left (as shown in the second row). Gstreamer can handle that. Ok. Now the data is send to the decoder (= box drivers / hardware). You need to inform the drivers that it should playback the frames in the reverse order. YXWVU and not UVWXY. How can you do that? You can't, because the DVB API only knows fast forward.

http://www.linuxtv.o...000000000000000

http://www.linuxtv.o...000000000000000

 

I guess that's why fast rewind also for TS files is not handled in HW (drivers).

[Erik Slagter]

Indeed. Every kind of trick mode must have support in the drivers and in the decoders (hardware).

@betacentauri.

 

Yes it's possible that fast rewind will not  be possible. however i've got some hopes cause we can rewind in function off frame-key then . But indeed could be that it won't work with the current dvb drivers.

 

gst-1 has well good api support which was not the case by gst-0.10. But if api does not support back indeed fast rewind will not work.

[christophecvr]

Also a small note for persons ho build image with gst-1, perviousely we used a patch disable-subtitle-hack  in to the current enigma2.bb for gst-1 on github this patch is not included anymore. With the latest enigma2 update its done automatically for gst-1 (only).

 

Persons who did not update to the latest pli gst-1 branch and are using an own made enigma2.bb do not forget to remove the patch out off you're own enigma2.bb

[samsamsam]

Fast rewind can be handled based on IFRAME only, but what for? Do you really use that?

You can inject IFRAME's only and then there is no need to support in drivers.

 

Why you not use this feature on PC? Because you have free jump...

 

Art for art's sake.

OK now?

[betacentauri]

What media framework is used by the Chrome browser?

Yes. This is ffmpeg.

 

Part of project using ffmpeg:

https://trac.ffmpeg.org/wiki/Projects

 

Oh gstreamer use ffmpeg hehe

But ffmpeg not use gstreamer.

 

Only saying others are using it, doesn't really help. It's no "proof" that it's better. Also memory consumption is for me a minor advantage. Current boxes have plenty of it.

What are the real advantages of ffmpeg? Which files can be played with ffmpeg which cannot be played with gstreamer? Or what streams are working better? If there are any, what is better? No interruptions, better support for seeking,...??

[christophecvr]

Note I curently updated to gst-1.5.2. Both boxes (dm8000 and vuduo2) with updated github enigma2 are running perfect.

 

For the ones interested here the gstreamer recipes with gst-1.5.2

 

I could make a patch for gst-1 branch git.

I'm not going to "proof" any one. 

The problem is that You and several persons "beelive" in gstreamer. It is OK. But please make the simple test with FLV file and we will see "memory consumption is for me a minor advantage.". And than check if memory is free after playback stop.

Are you using only local media to test? Or maybe you try also IPTV streams?

[christophecvr]

I already tested with some iptv streams and it worked.

 

If some can send me some links iptv streams I can insert it in a bouquets and test more explicit.

[Taapat]

What are the real advantages of ffmpeg? Which files can be played with ffmpeg which cannot be played with gstreamer?

 

The main reason why I, on my sh4 receiver don't want use gstreamer, is that it doesnt know how to play my previous receiver records.
You can try: https://taapat-enigm...ets_LTV1(1).mpg
It is a record with a lot of waste in it. Of course this is the exception, but libeplayer plays it with no problems, as well as many other formats.

For example, using libbluray library in ffmpeg it knows how to automatically select bluray tracks.

My C++ knowledge is very low but I've tried to create a separate file for libeplayer, based on servicemp3: https://bitbucket.or...l.cpp?at=master
As you can see in the code it is many times simpler.

 

But I agree with littlesat that a lot of energy and knowledge is investment in gstreamer, and I do not believe that anyone will want to change something.

[christophecvr]

Indeed that old file does not play it gives :

I'm not going to "proof" any one. 

The problem is that You and several persons "beelive" in gstreamer. It is OK. But please make the simple test with FLV file and we will see "memory consumption is for me a minor advantage.". And than check if memory is free after playback stop.

 

You get me wrong. I don't care whether ffmpeg or gstreamer is used as long as it works good. Currently Gstreamer is included and it works. Perhaps not perfect, but quite good. So why should we spend days/weeks to switch to ffmepg? It needs to be worth spending time to change it. If you or someone else show me real advantages, I might help switching to ffmpeg. But perhaps it's also the case that something works worser in ffmepg than in gstreamer... who knows.

 

In gstreamer 0.10 there was a bug, which consumed very much memory when using a file with much subtitles or external subtitles. With gstreamer 1.x I don't have the problem.

 

Do you have a link to a flv test file? Or can I use every flv file?

[christophecvr]

Yes cause subtitles are working ok now, with gst-1 no execif prebuffering more. I now start works to reimplement the vobsub support. (only internal) . This for mkv and m4v movie containers.

Every. The problem is well know. The memory is taken for indexing frames not for subtitles.

 

Why ffmpeg? For example:

How much time was needed to switch to gstreamer 1.x? 

libeplayer3 at start use ffmpeg v0.8 but simple update to ffmpeg v2.7.1 and everything works.
