Media Information (Ctrl+I) bug/feature?

[ev1te]

For some video formats the framerate and resolution is displayed in the media information window under Codec Details (Advanced Info. in v0.8 ). But for most of the formats I use, DVD for example, there is no way to see what resolution and framerate the video has?!

Since this haven't been fixed, I guess it is not classified as a bug that the information about the played media is lacking for some formats, and why is that ? My question is simply, how to display some kind of advanced information that includes framerate and resolution? Since the resolution can easily be measured using print screen and a image processing software (if the aspect ratio doesn't interfere) and the framerate can be calculated from the decoded blocks information under Statistics(but not very accurately) why can one not see those values directly under Codec Details?

I don't think it has ever been in V0.8
I could do that for V1.0

Mmh, I've tested 3 video files and one DVD.

The statistics page was always non-functional, like this: Statistics

Here are results for three different files: File 1, File 2, File 3 (file names pixelized).
Playing the DVD gave this: DVD

I've found another bug: When drag&dropping a video into a running, video playing instance of VLC or start them via double click (also when VLC already runs) the pages "Extra Metadata" and "Codec Details" remain empty!: Metadata, Codec Details

Yes, it would be nice to have the resolution and framerate of the different video tracks in a DVD under the Codec Details (as it was meant to be I guess).

I also found two bugs, at least on my computer.
Bug! The FPS counter under the statistics tab doesn't work, it always shows "0" (at least for me), but decoded blocks works and since "delta decoded blocks" = FPS -> this would easily be fixed.
Bug! The text in the left part of the statistics tab is cut of due to, too narrow columns. -> make the columns resizable.



Is there other people that would like to see additional statistical information?

Here is some examples of additional information fields under the statistic tab that I would like to have (realtime information);
Fix/Bug/Feature! Display resolution and framerate of all video streams under Codec Details when viewing DVD's or other formats with several video streams.
Feature! Display original resolution of video stream that is played right now.
Feature! Display rendered resolution. (Good for cases when the VLC window is resized or if the aspect ratio changes the displayed resolution from the original)
Feature! Bitrate of video and audio separately.
Feature! Information of which streams that are played right now, in a DVD with several streams under Codec Details it is difficult to see which one is the actual video and which is the menu.

Resize of column is fixed.
FPS is fixed by being removed because it is not working.

That was fast!

Is there some other way of seeing statistics when playing a media file? console maybe?

[Jean-Baptiste Kempf]

No.
DVD Resolution isn't displayed, because it is supposed to be standard.
Rendered resolution, this has nothing to do with the file data, so it has nothing to do with this dialog.
Bitrate of audio and video are already in the codec part.
Showing the selected one is a good idea.

No it is not standard, since you have NTCS and PAL, both which supports 4 different resolutions (8 total). If you do not know if the DVD is PAL or NTSC and you want to find out which one it is, one could look at the resolution and the framerate. For bluray discs the movie can be ether 720p or 1080p i think (don't have a bluray reader myself)?

Rendered resolution, this has nothing to do with the file data, so it has nothing to do with this dialog.

I agree to some extent; But since you don't have any information regarding the displayed size of the video, maybe the default aspect ratio would be a more realistic feature in that case. Since many videos have aspect ratios that doesn't correspond to the aspect ratio of the video stream. (placed under Codec Details or directly under Aspect Ratio in the video drop down menu so one can see which aspect ratio that is choosen for the moment, by the way that menu lacks the anamorphic aspect ratio of 2.35-40:1)

Bitrate of audio and video are already in the codec part.

I don't agree; This only works if you have a format that actually displays the information of the video and audio in the codec details, which it doesn't for DVD's for example. Also for most videos you have variable bitrate which requires one to see realtime bitrates to be accurate, even some cheap dvd players i have seen can display realtime video and audio bitrates on screen.


I have some basic programming skills myself which says that displaying some basic information should be easy, but when it comes to media and entire programs which is something that i haven't had much experience with, it is not always as easy to understand which features requires more work than others.

Thanks for the good response!

I'm not entirely sure, but where it comes to the Media information dialog, I believe one of the problems is that we can only display information that is known after the Demux state atm. Unfortunately, DVD resolution is not known until you start decoding the video.

That explains why there are basic information missing out or bugs with different formats.

I hope the dev's in the future takes the time to add some of these features since I have seen many other threads on the net of people using (wanting to use) VLC or other programs as measurement of frames in high speed cameras, or for personal dvd making etc. Adding some of these features would probably increase the popularity of VLC.
