Configuring Conversion Rules in FF DownloadHelper


I want to burn VCD's and DVD's from flash videos that will play in a standalone DVD player but have been unsuccessful at finding the correct combination of conversion choices in DownloadHelper. This is my 3rd or 4th request for help on this. Someone out there must be successful at burning. Avidemux, DeVeDe, and DVDStyler have been no help. Any recommendations would be appreciated. Thanks Michael.

Tovid will work. I use it to convert flv videos to mpg, and then, with dvdstyler, I can create a playable dvd. In fact, you may not even need dvdstyler, as I believe tovid will also burn discs after it has encoded the video file (however, I'm used to using dvdstyler for the last step in the process.) Once you install Tovid, run it with the command "tovidgui" (at least, that's what I have to do with the version I've got installed on Debian.)

BIG THANKS MARK,
Tovid happens to be in the Linux Mint repositories so I will load it up and give it a shot maybe during the coming week but most likely next weekend. I spent a good deal of time this weekend producing coasters struggling unsuccessfully to crank out some usable VCD's and DVD's I'll post another reply after I try Tovid to let you know how it worked out. Again, Thanks, Michael.

NO GO ON TOVID MARK
I gave Tovid a short effort tonight and had nothing but problems. I was going to send in a bug report and that was a big hassle also so I'll just keep fooling with DownloadHelper and hope someone posts the correct parameters for conversions. No luck on conversion codex's from here, the Mint forum, or Craig's List forums. I gotta a lot of hours in this and a lotta coasters.
Before RealPlayer got sued by Roxio or someone, I forget exactly who, in Windoz XP Pro I could convert flash videos and burn them no sweat. After the suit, they changed the program and now you can only convert into a limited number of formats, mostly for cell phones or game players, not standalone players.
My next step is to methodically write out a permutation chart of the codex choices and begin a very long process of testing. Very boring and time consuming.
Anyway, thanks for your efforts. Michael

I'm surprised. I've been able, with Tovid, to convert flv files (or avi, or whatever), to mpg, and then create DVDs. Another possibly better program is cinelerra. Install this program, and then install its documentation, and it will tell you how to render a video file (like flv) to mpeg2, which can then be used to create a dvd with dvdstyler. The link I provided gives some repositories where cinelerra is available, but it may also be available simply in the multimedia section of your distribution.

Anyway, here, below, is what they say for converting video files (like flv) into dvd burnable files (mpeg2, or, more simply --> mpg), using cinelerra. Note, I've tried this, and it works well. Once I get the mpg files, I use dvdstyler. You can also use cinelerra to join several smaller videos together.

20.9.1.2 yuv4mpeg pipe through ffmpeg

1. Select File->Render... or press <SHIFT-R>. The render dialogue pops up.

2. In the render dialogue, you have the choice to render (a) the entire project, or (b) the highlighted selection, or (c) from In-point "[" to Out-point "]".

3. Make sure the Insertion strategy is "Create new resources only".

4. Select the AC3 audio output file format.
5. Specify the audio output file name and path (example: your-movie.ac3).

6. Select Render audio tracks and deselect Render video tracks.

7. Click on the wrench next to "Audio:". A new dialogue "Cinelerra: Audio Compression" pops up.

8. Set the bitrate to 128 kbps (or leave it there).

9. Click OK, the compression dialogue disappears.

10. In the render dialogue, click OK, the dialogue disappears. Audio is rendered. Rendering audio is much faster than rendering video but might still take some seconds. Watch the progress bar in the main window's lower right corner.

11. Again, press <SHIFT-R>. The render dialogue pops up again.

12. Select the YUV4MPEG Stream file format.

13. Specify the video output file name and path (example: your-movie.m2v).

14. Deselect Render audio tracks and select Render video tracks.

15. Click on the wrench next to "Video:". A new dialogue window "Cinelerra: YUV4MPEG stream" pops up. The first textbox should already contain the output filename and path you had specified in the render dialogue.

16. Select "Use Pipe:".

17. Fill the following command line into the second textbox:
Code:
ffmpeg -f yuv4mpegpipe -i - -y -target dvd -flags +ilme+ildct %
18. Click OK in the yuv4mpeg dialogue and in the render dialogue to render video output.

19. The resulting .m2v can be further processed together with the .ac3 audio with the following shell command, producing a dvd-compatible mpeg stream:
Code:
ffmpeg -i your-movie.ac3 -i your-movie.m2v -target dvd -flags +ilme+ildct your-movie.mpg
(Yes, the stream is sent through ffmpeg a second time.)

Note on ffmpeg command line options:
-i tells ffmpeg to read from standard input (in our pipe, this means from Cinelerra's render stream).
The -y option allows to overwrite existing target files (of course, it is safer to omit this, but then you must make sure to rename or delete previous results each time you want to render a new version).
The +ilme+ildct flags are for proper interlacing, bottom fields first, tested with PAL footage. Some Cinelerra versions suggest a similar command line in the ffmpeg pipe presets for DVD, however with erroneous syntax of the interlacing flags or without the flags.

Before proceeding to put your rendered mpeg2 data on DVD, you might want to watch and check your-movie.mpg in mplayer or xine/kaffeine.

Actually, before trying cinelerra, I think you should try tovid again. After you've pressed the "Add menu" button, and then pressed the "Add video(s)" button, select the listed video. You'll see a drop-down list that gives options for encoding. Instead of the default "mpeg2enc" option, instead choose "ffmpeg" option. Then, press the encode tab, start encoding, and hopefully it will work. For me, the "mpeg2enc" option never works properly; so, I use the second option, which is the "ffmpeg" option. This really should work.

If not, then try cinelerra, as I suggested above.

ffmpeg pipe through cinelerra

I am new to Linux and am trying to edit video to create a dvd. I am using Debian lenny and have installed cinelerra (squeeze - I previously installed lenny version but had this same problem which I see has not gone away with the squeeze version). The problem is this:
When I try to render video using yuvmpeg4 exactly as described in the manual and as reproduced in this thread, I get a failed read/write error. I have tried various versions of
ffmpeg -f yuv4mpegpipe -i - -y target dvd -flags +ilme+ildct %
now in 2 different versions of cinelerra (lenny and squeeze) and get the same results. The audio using ac3 rendering worked fine. I do not know where to go with this as I have been working on it for some time to get it to work. Any suggestions would be greatly appreciated.
Thanks,
T
