MPEG-2 TS Aspect incorrect #117

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
When reading TS with TS Reader Lite, aspect shows as 1:1. Aspect is ok in most 
other programs (VLC, Mediainfo, etc), but TS Reader shows what most set top 
boxes will read.

Can you send me a file that correctly show 16:9 ? Thanks

Sure can:

http://71.13.12.26/TS

Please let me know if you need one out of ffmpeg that shows the incorrect 
aspect... though I'm sure you can make one of those.

So I re-encoded this video using:
ffmbc -i <file> -b 6000M -bf 2 test.ts
and TSReaderLite shows 16:9 as aspect ratio for test.ts

So I think it works as expected

I just tried doing exactly what you wrote (with the exception of a lower case 
"M" for the bit rate), and I still get 1:1 aspect ratio in TSReaderLite

could you send me a file you made with ffmbc that shows 16:9 in TSReaderLite?

I'm still getting 1:1... though I do see 16:9 on your file.

I'm using a Windows build of ffmbc, is that what you're using?

C:\Test>ffmbc -i test.ts -bf 2 -b 6M test2.ts

Strange.
No I'm using ubuntu, are you using the build supplied in the downloads section ?
I know it was an issue before rc7 but it was fixed, and I can confirm that it 
was fixed on my side.

Original comment by baptiste...@gmail.com on 9 Dec 2012 at 10:46

GoogleCodeExporter commented 8 years ago 
Yes, I was. I just re-downloaded (FFmbc-0.7rc7-win32-120705.zip) and re-tested 
to be sure.

So, does that indicate that it is an issue with the Windows build?

Are you able to test the current Windows build? I'm using the 32-bit, but I 
believe I got the same results with the 64-bit version - though I can test that 
one again if you'd like.

GoogleCodeExporter commented 8 years ago 
I just tested 64-bit - 64-bit works! 16:9 aspect is set correctly.

Would you be able to see about getting a fix for the 32-bit version for Windows?

Thanks so much for your help in the development of this.

GoogleCodeExporter commented 8 years ago 
Well, rc8 is not too far away so it would be fixed with it I think

Original comment by baptiste...@gmail.com on 10 Dec 2012 at 8:41

GoogleCodeExporter commented 8 years ago 
Great, I will look forward to it.

Original comment by john.dac...@gmail.com on 10 Dec 2012 at 8:48

GoogleCodeExporter commented 8 years ago 
Would you be able to contact the individual who compiles the Windows builds to 
alert them to the issue?

Or do you think I should open a new ticket for this specifying that it is only 
the 32-bit version that exhibits this problem?
