FLV Extract

[[ReX]]

M4A muxing works, but shows a dialog with no text before muxing each file for some reason. MKA has no problems.

I think i forgot remove a MessageBox that i made for test

Hello,
I don't know if I'm doing something wrong because I haven't seen my problem anywhere. Everytime I extract an FLV that contains an AVI file inside, it disappears after it's done (only when I have the setting: remux to mkv). Everything else works great.

Thanks for your feedback.
have you set disable for the option "Remove temp files" yet? Or can you please send me link of the file you're trying to extract (mediafire like please) so i can check it detailedly.

Yes, I've tried the disable "Remove temp files" and they don't disappear but I was curious why they don't remux into MKV. Here's the link to an FLV file with an AVI inside:

Mkvmerge can mux those streams without a problem, so probably the command-line generated by the GUI for remuxing is wrong. (expecting ".264" instead of ".avi"?)
But FLV1 video in mkv will not offer great compatibility anyways...

it might be true, if i remember right, i didn't use switch case for .264/.avi in here (i don't like avi muxing into mkv as well).
I will fix the code a bit.

I did add the case for avi input file, but i wonder the command-line is still wrong format?
---
I found the problem in here, the command-line for avi input file got repeated.

And there are still a problem in setting ratio for mp4 file :/ it needs both of input/output file ratio, and i still dont know how to set values of command-line right.

It's got typo from the start so i don't want to chance the url (or maybe not allowed) of Google page, it might be a problem

[N586Z]

Wow, that was quick!

[jofori89]

anyway, anyone has a way to set ratio for output file of mp4 file? I dont get what method Yamb used in muxing at all

Some folks are having issues with extracting files to the correct framerate. 29.97 ends up playing at 33.303fps. I don't have the source file to find out though.

Yeah, i got that bug too when i tried remux some 29.970 FLV files from youtube to MP4. If i did not specify the output framerate but just leave it be original, it become 25fps. There are not that bug with mkv

It seems to be a common issue: par in mp4box

well, when i tried change a 6:5 video to 16:9 video, it showed correct in Video info but still incorrect in video player.

ratio = "ar=1.78:1.33";

If you have a video with storage ar of 6:5 and need a display ar of 16:9, par is 40:27 ( 1.48:1).

that is what i wanted to know, how to get that 40:27, and not like mkv doesn't require storage ar to calculate display ar.

Currently there is no code to auto get ratio of flv video in project, should i let user manually input resolute of video?

How about offering the ability for users to input their own settings within the 'FPS' and 'Aspect Ratio' boxes?

mediainfo (or whatever) --> get storage ar
user input --> set display ar (4:3, 16:9 ... custom)
FLV Extract --> calculates "PAR"
