auto downscale ffplay sdl windows regression

[burek]

Summary of the bug:
The entire thread can be viewed here: ​http://ffmpeg.gusari.org/viewtopic.php?f=26&t=856

How to reproduce:

ffplay -i "FileName"

and after that pressing the "F" key.

This version of ffplay works as expected: ​http://ffmpeg.zeranoe.com/builds/win32/static/ffmpeg-git-41a097a-win32-static.7z

This version does not work: ​http://ffmpeg.zeranoe.com/builds/win32/static/ffmpeg-20121105-git-c995644-win32-static.7z

So this is possibly a regression of some sort and should be investigated.

[Carl Eugen Hoyos]

Please add the complete, uncut console output of your failing command.
If this is a regression, please find the change introducing it.

[burek]

Please read the forum post.

[Carl Eugen Hoyos]

Please reopen if you can add the missing information.

carl , can you leave these bugs open so others can work on them, even if they dont have the information in the trac?

Why don't you read the forum entry, reproduce the ticket, add the missing information here and reopen the ticket? (If the problem really is Zeranoe-only, it will probably help more to either post on his forum or contact him directly, I suspect he is not following this tracker regularly.)

This ticket is missing information about how to reproduce the problem as well as a description of the problem. It may be on the linked forum but that is IMHO not ok. copy and pasting at least 1 paragraph or writing a summary is neccessary. I also tried ffplay random file and "f" switched to fullscreen as expected
so iam no smarter from that.

I agree with this for one simple reason: the ticket will still be understandable in 1, 2, 3, or 10 years even if the forum doesn't exist anymore.

On a practical note, it's also handy for developers not to have to crawl another forum thread just to pick hints on the problem.

[burek]

ok, i'll avoid reposting forum issues here in the future and let people decide if they want to do it themselves. it's even easier for me that way, but it will be ffmpeg project's lost.. after all ffmpeg needs bug reports, and those users that experience those issues probably won't have time nor will to report anything, they'll probably move to another tool/player or they will wait for some time and check if the bug is gone.. the grand total is that ffmpeg is loosing the information it needs, the end users will quickly adopt to some other tools even if ffmpeg project dies at some point (god forbid).. so, for users, it's not a big deal, but i guess for ffmpeg it is..

imho it is far better to leave some (maybe even invalid) tickets open (i mean it's not like they cause cancer or something), rather than close them pretending they never existed :) it looks to me as if some people are afraid of open tickets and they close them as soon as they find any reason to do so, which is rather funny to me :)

[compn]

if i must, i must... :)

i can report reproduction of bug. in old version, with desktop res set small , say 800x600 , if you open a file which is larger than the desktop res (say 1920x1080) then ffplay will automatically downscale the video when pressing f to fullscreen.

Is the problem reproducible with the following commands?
$ ffmpeg -i tests/lena.pnm -s 4000x4000 out.png
$ ffplay out.png
(and do I understand correctly that ffplay -fs out.png works fine?)

[compn]

ffplay out.png opens a video window. i am able to see the part of the image that fits on the screen. so i get to see a corner of the 4000x4000 image, due to my small desktop size.

ffplay -fs out.png does not open any video window.

ffplay also hangs here and needs ctrl-c to return back to cmd prompt.

if anyone wants me to test some ffmpeg revisions, i will be happy to.
bonus if you link me to the zeranoe static build you want me to test.

[compn]

also, viewing a small res video (smaller than my desktop res, say 720x480 on a 800x600 desktop resolution)
when i ffplay -fs file.jpg my monitor goes blank like when its changing the resolution. then it returns to normal and the jpg is on display in windowed mode.

if i press f again, nothing happens.
if i press f one more time, ffplay finally displays the small res file fullscreen.

ffplay out.png
press f once = rescaled image to 720x480 somehow?
press f twice = nothing happens, still windowed 720x480 image
press f three times = full screen properly scaled image

hope this clears it up ;)
