@WanWizard: If a hd51 rc 7.0 image could be available before 8 o'clock pm, I can test it. Afterwards 2 records start.

 

I'll try, but don't hold your breath, the current rc run that started 12:00 GMT+1 isn't finished yet.

I didn't know that we used there hardcoded values.

We need to use something like videoStream::vtH265_HEVC

So if we choose to change internally something it won't break again.

Generally E2 if full of hardcoded values.

I just tried to use the same values everywhere and expose them to userspace in order to have the codec in UI.
 

lib/dvb/decoder.h:	enum { MPEG2, MPEG4_H264, VC1 = 3, MPEG4_Part2, VC1_SM, MPEG1, H265_HEVC, AVS = 16 };
lib/dvb/pmtparse.h:		enum { vtMPEG2, vtMPEG4_H264, vtVC1 = 3, vtMPEG4_Part2, vtVC1_SM, vtMPEG1, vtH265_HEVC, vtCAVS = 16 };

// not finally values i think.. !!
#define VIDEO_STREAMTYPE_MPEG2 0
#define VIDEO_STREAMTYPE_MPEG4_H264 1
#define VIDEO_STREAMTYPE_VC1 3
#define VIDEO_STREAMTYPE_MPEG4_Part2 4
#define VIDEO_STREAMTYPE_VC1_SM 5
#define VIDEO_STREAMTYPE_MPEG1 6
#define VIDEO_STREAMTYPE_H265_HEVC 7
#define VIDEO_STREAMTYPE_AVS 16

@athoik: Why did you add the "= 3" for vtVC1?

As I said now streamtype is equal everywhere. So streamtype = 3 = vc1.

My 7.0rc is from 20th december

Sw Update works?
Clear I made everytime before updating an image backup ;-)

[betacentauri]

@athoik: Yes, you be great to use only 1 enum in E2 and use it everywhere. We should put it on the todo list...

A new rc build for the uno4kse  is finished, I'll start one for the hd51, just in case.

[anudanan]

Is the uno4kse rc Image from today 19:11 in the download area? Can I also make a sw update to test it?

i do it in 1 houre after watching a movie

[WanWizard]

Also finished.

[anudanan]

It works now with travelxp 4K and UHD1 by Astra

 

Also the reconstruct works

 

But one question

 

a record of RTL UHD only creates an SC file but not an AP file. 

[betacentauri]

Yes, on SES UHD Demo Channel ap and sc files are created.
On RTL UHD I couldn’t test as I first need to install and configure oscam. Can’t do it today and also the next days it will become difficult.
But I will check it. If not, please remind me.

[anudanan]

The special thing on RTL UHD was today that there is only a still picture you can see.

 

Ist that a reason for the missing AP file?

[betacentauri]

If you only recorded a few seconds, then most likely yes. Ap file contains the position of I frames (maybe called differently in the h265 standard) to be able to cut without de- and encoding of the video data.

[anudanan]

Now I made a record of the still picture for 20 min but there is  no AP file.

 

I´ll make a next test when the RTL UHD channel will send a normal  movie

[betacentauri]

h265 uses NALs. The "access unit delimiter" NAL show which kind of frames are included in the data. There are 3 possibilities: Only I frames, P and I, B and P and I (see h265 spec). Currently we only search for the "only I frames" case. This seems to work in several cases, but not on RTL UHD. Maybe only because RTL UHD shows at the moment a still picture only changing every few minutes.

[betacentauri]

@anudanan: Does cutting h265 recordings work properly? So are there any artifacts visible after cutting?

 

For RTL UHD we currently don't have a good solution. Only a quite complex implementation might fix the problem. But as it's only one channel and the channel really don't transmits something useful, I don't really like to implement that.

[anudanan]

Yes, cutting works fine.

 

I´ll check RTL UHR if the channel send normal program

[betacentauri]

It only shows Formula 1 in March 2019. So we have to wait "a little bit".

[anudanan]

Tomorrow I will make a record of RTL UHD  formula F1 racing to check if the AP file is now there and then I will cut the movie

Edited by anudanan, 16 March 2019 - 19:49.

[anudanan]

I works. Now the ap file is also there if a recording is finished. Cutting works also

 

I have seen today RTL UHD has used an AC3+ audiotrack, which I only can hear if I have AC3 downmix enable or PCM Multi enabled. I think that has to do with my older AVR which can´t decode AC3+ so the Box must do it. Last year I have heared audio with my AVR Maybe that RTL has swich to AC3+ this year.
