Didn't tell you guys, I am restoring a Crosley 817.

https://www.radiomuseum.org/r/crosley_817.html

Electrical updating is done plus adding the optional aux input as shown in dotted lines on the schematic. There is a new phono jack and DPDT switch that selects radio/aux and at the same time grounds the grid of the 2nd IF to cut off radio signal when in the aux position. Ya gotta kill the radio in aux! So really minimal design changes, just the switch. Played it from a bluetooth board and it sounds great. I'm sold on push-pull with a big speaker. And that warm tube sound nonsense, ok.

Working on the case too. Gonna be amazing. I say case now because cabinet feels foreign foo-foo icky.

And then I can tell you about the two VTVMs I restored. So little time.

In the coming winter it can be an effective heater.

Did you see Mick Jagger simping at the King Charles Macron love fest?

Yup, upchucked big time.

I'm thinking of doing at least one bakelite AA5 and after that an early transistor radio. Just to cover the end of the wood tube radio era. Then a TV. Watch out!

It's heresy, but what I like to do is scrape off the lacquer and do a restain followed by two coats of hand-rubbed poly gel topcoat. If some dumbass wants to spray it with lacquer ok go ahead. A radio is not a frikkin piano!

Amen. The wise do at once what the fool does at last.

Hi Sherman my dear,

I started testing dgdecodenv linux 501 with some TV captures.

Input AVC stream with resolution 1280x632, same size in .dgi file.
See extract from .dgi file below.

DGAVCIndexFileNV100 DGIndexNV 2053.0.0.501 X64
/usr/local/bin/
/home/frankaboy/Demux_2D/Lost_in_Fuseta_Teil_1_1280x632_bt709_x264.avc

SIZE 1280 x 632
FPS 50 / 1
CODED 264672
PLAYBACK 264672

Is this behavior correct?

Post by **Sherman** » Tue Sep 26, 2023 11:47 am

Looks good to me. You're testing a size without a cropping rectangle. Thank you for your testing.

Next I am going to do the log file creation for you.

Hi Sherman,

may you can check creation of X265_CL for an hevc video stream, please.

The .dgi file shows:
X265_CL --colorprim 2 --transfer 2 --colormatrix 2
--master-display "G(8500,39850)B(6550,2300)R(35400,14600)WP(15635,16450)L(10000000,50)" --max-cll "0,0" --frames 3064 --chromaloc 2

Is --colorprim 2 --transfer 2 --colormatrix 2 correct?

I normally use these x265 encoding parameters
--colorprim bt2020 --transfer smpte2084 --colormatrix bt2020nc!

It reports what is in the stream, which in this case appears to be 2 = unknown. If you think that is wrong please provide a source sample. Thank you.

Of course, you can modify the settings as you like, as long as you know what you are doing.

Hi Rocky,

many thanks for your response and explanation.
I didn't know, that 2 = unknown.

You are welcome. See here and scroll down to --colorprim:

Hi Sherman,

I have finished now all tests with dgdecodenv linux 501.
Following streams I have used for testing:

TV captures:
1280x580, 50fps, x264 encoded video
1280x632, 50fps, x264 encoded video
1280x548, 50fps, x264 encoded video
1920x1080, 25fps, x264 encoded video

BD source:
2 x 1920x1080, 24000/1001fps, stream from original BD

UHD source:
3840x2160, 24000/1001fps, stream from original UHD
3840x1600, 24000/1001fps, x265 encoded video (cropped black borders)
1920x1080, 24000/1001fps, x265 encoded video (cropped and resized)

All tests done without any issue.
You have done great work, many thanks again. :bravo:

Bravo, Frankaboy! My number one tester. Thank you.

Told you guys, that's why Balzac won't come back to the present. Figure it out.

The 10-word sentence rule?

Post by **Curly** » Sat Sep 30, 2023 1:05 pm

not genius thinking if your a ruler you rule, if not not

Post by **Sherman** » Tue Oct 03, 2023 12:02 pm

Frankaboy, I've got the log file working. So far implemented AVC data. Moving on to the others.

It's just a guideline, useful for communicating with low-IQ types. I'm trying to decide between Balzac and Judy Garland to bring back. Maybe Shirley Temple?

Great

Did you make a new release?

Post by **Sherman** » Wed Oct 04, 2023 9:31 am

Not yet. Gonna finish the other formats first.

Post by **Sherman** » Thu Oct 05, 2023 11:58 am

HEVC is done. Now need to do MPG2 and VC1.

Just so you know, there is no NVDec in DGIndexNV (linux) so I am adding the needed parsing code.
