Batch FLV Converter/Decoder

[Qjimbo]

Here's a rough piece of software I wrote in Delphi to help batch convert FLV files to MPG/AVI with FFMpeg:

http://share.ovi.com/media/luisfelipe7.programas/luisfelipe7.10060

You can select multiple files when adding them to the batch list, and currently it only allows you to reuse the source audio in the FLV files (since I didn't want any more data lost) but you could edit the batch file afterwards and do a find and replace on "-acodec copy" with whatever audio settings you want.

I just needed a program to do this so I wrote it, maybe some other people will find it handy!

EDIT2: New new download URL! This time I don't have to worry about hosting it. If link fails just google flv_convert.zip .

Thank you for the kind words everyone!

messa think thats spam above :P

AutoIt would have been a good language to choose for building a quick and dirty front end. But the tool works, though it's a bit basic...

Good job. Does what it says. I used it to convert http://movies.collegehumor.com/items/2006/04/collegehumor.1682247.flv

Thanks!

Well it works unless the video has VP6 compression (Flash 8 default). I'm currently not able to find any way to convert these movies to AVI. But I think I'm getting close thanks to Gabest's FLV splitter. See this thread (http://forum.doom9.org/showthread.php?t=108070&page=2), if you're interested.

Wonderful looking tool except it doesn't convert my flv files. Any hope that you could update it to work with VP6 compression ?(vlada's analysis) or maybe a quick guide that I could follow to modify your script? I've spent a week now trying to convert some pesky flv clips and finally found a player that at least plays them.

[vlada]

You should better ask FFMPEG developers to include new FLV splitter and VP6 decoder. Anyway I was finally able to convert the VP6 FLVs using Gabest's FLV splitter and his VP6 DirectShow decoder. You can find it in a thread about new MPC. After "installing" the splitter+decoder, you can convert your files using AviSynth or Graphedit.

I downloaded some .flv videos from YouTube but this thing won't convert sound, it only wants to convert the video. Any help is appreciated, thanks.

[vlada]

I would suggest you to download FLV Extract (http://www.moitah.net/#FLVExtract). It will extract the sound (I think YouTube uses MP2) and The video will be converted to AVI.

[sammo_cat]

Thank you very much for your terrific app.

I have been battling for a long time and resorted to the use of screen cap programs.



It took all of four or five clicks to make yours work.

Great job .


P.S. I think maybe in your spare time you could write a new operating system to replace XP for us all to use too.


P.S.S.
Screw the whiners and there remarks , nice one thanks


Thanks again , Sammo

I officially nominate you for king of the flv universe. You totally rule!

I've been using Riva FLV Encoder, which hasn't been too bad but hasn't been too great either. I've tried many other "free" (trial) pieces of software and other free don't-actually-work pieces of software. All I want to do is convert YouTube vids into mpegs so I can take them over to my parent's place. Is that really too much to ask???

Finally, something simple and easy that works!!! Thanks!

[tony_gr]

I test many FLV decoder software. It seems that Replay converter is more easy-to-use. Get it Here (http://www.soft29.com/dvd_video/video_converter/flv-converter.html)

I downloaded some .flv videos from YouTube but this thing won't convert sound, it only wants to convert the video. Any help is appreciated, thanks.

Actually I've had this problem with any ffmpeg-based program. Converting the audio works fine (like to PCM during playback or to any other format during a transcode), but a stream copy fails.

Anyone know why?

I would suggest you to download FLV Extract (http://www.moitah.net/#FLVExtract). It will extract the sound (I think YouTube uses MP2) and The video will be converted to AVI.

Youtube uses MP3 AFAIK. 22khz mono @ 64kbps

Have you tried to run FFMPEG from command line, to check if the problem is there too?

According to YouTubes's audio format - most files I recently chcked were really MP3. But I remember some FLVs with MP2 too.

Yes, actually I haven't tried to run the frontend yet :p

Both Mencoder and FFMPEG fail. I remember one time I got an "Error, Skipping Frame!" message but usually there is no valuble output. Here it is anyway:

Here's another file. This is the error I usually get. Also the file ffmpeg produces when played back is said not to be "properly interleaved" to the point that the AVI splitter falls back to the Microsoft one.

Any ideas on what's going on anyone?

[Qjimbo]

Problems relating to lack of audio are more likely due to the fact it leaves the audio as MP3, and not all MPEG splitters support MPEG Audio layer 3 (though they should really). The default codec supplied with Windows XP does, but others, like the Mainconcept decoder, don't.

[PatchWorKs]

...and what about MediaCoder (http://mediacoder.sourceforge.net/) ?

[cast42]

There's an online converter on http://vixy.net that remove the Flash container around the H.263 video stream and MP3 audiostream. The elementary video stream is then muxed with a MP3 or AAC audio stream. Result can be AVI(Divx+MP3), MP4(MP4+AAC), MOV or MP3 only. The conversion software is open source: http://sourceforge.net/svn/?group_id=183657. Remark that Flash video 7, as used by Google, is essentially H.263 video. H.263 is compatible with basic MPEG-4 Part 2 so no decoding/encoding for the video is necessary. Only another filecontainer is applied.

converts my 3 youtube .flv files - no problems

[youtube007]

For converting flv to avi, mpeg, etc. I use FLV to Video Converter
http://www.flvsoft.com/flv_to_video/
This software easy can convert these files. I use it long time and I haven't any problem with it. Based on batch conversion and Process Nellymoser audio FLV well for me, You can try it too. it is a desktop version programe, if you want to convert with command line, I recommend FLV Converter SDK (http://www.flvsoft.com/flv_converter_sdk/) to you, It offers the professional solutions to convert FLV to video formats directly online with the command lines, Good luck to you!

[vlada]

Why should I pay for such program if there are many programs which can do the same job for free and probably with higher quality? For example Avidemux or FLVExtract.

[Maha]

:confused:

[youtube007]

if you stick to freeware, you can try super, but when i used super, Freezes every time I click the "Encode" button after dragging and dropping an FLV file into the program. Batch convert FLV files to video formats directly online with the command lines, I used FLV Converter SDK (http://www.flvsoft.com/flv_converter_sdk/),The programe support development environment like VC/VB/Delphi/ASP/.Net, etc. or you can google its name to get it, Good luck!

Nothing special.
Not worth to try and buy.

I'm can't see any information in EULA (license) about used FFmpeg in this 'tool'...
GPL violation?

:search: I found a very good prog - Flash To Video Encoder PRO!!!
I think it will be helpful to all =)))))
