FLV Extract

[[ReX]]

The MediaInfo DLL package has a C# example with a wrapper.

I know that MKV now supports it directly in v6.0.0 and FLVExtractCL.exe 1.6.3 w/ timecodes to MKV using v5.9.0 or earlier also works.

I'm trying to go from VFR FLV to MP4 & I tried using latest v0.22 of mp4fpsmod.exe to insert the timecodes but it didn't work (some error about "monotone").

So, my current method involves converting the VFR FLV container to MP4 containers using latest daily build of ffmpeg. They "appear" to be in sync.

But after examining the extracted timecodes of the converted mp4 files using both mkvextract (mkv as an intermediate) & mp4fpsmod.exe, I notice the timecodes differ from those extracted from FLVExtractCL.exe 1.6.3.

I trust FLVExtractCL.exe 1.6.3 because they match exactly those from an MKV converted from a VFR MP4 and then extract using MKVextract.

So, what is the best method to convert VFR FLVs to VFR MP4s.

Any help is greatly appreciated!

The timecodes of a VFR flv file often start like this:

# timecode format v2
0
0
0
40
80
....

Try to change that to something like:

# timecode format v2
0
1
2
40
80
...

Thanx.. Most of my timecodes contain something like:

# timecode format v2
0
0
1
3
43
83

OR

# timecode format v2
0
0
40
80

It's strange that mp4fpsmod could not handle such errors as it is VERY common in my FLVs.

Could I simply delete one of lines w/ the "0"?

Or if I do delete one line, do I have to add an extra line at the end?

I'm thinking of using a sed command in a bat/cmd file to batch process the timecodes text files....

Thanks...

Could someone compile and share a 64bit build of FLVExtractCL ?
Thanks!
