difficulty converting files with WinFF


January 26th, 2013
I am running an HP-Compaq dc5100 Pentium (R)4 3.20 with 796 M of RAM.
I have been running Linux Mint 14 Xfce for about a month.
Yesterday I installed WinFF—I wanted to download some Youtube videos in flv, convert them to wav, and burn them to a CD (we have found that someone suffering from Alzheimer's often finds the music from their youth comforting).
I downloaded sixteen videos with Download Helper, and then transferred them as a batch to Winff. I tried playing several of the files through WinFF with no difficulties.
I set the output details to Convert to: Audio and Preset: Wav for D and Output Folder: home/owner/Music.
When I hit “Convert”, the terminal opened, and it began to do its thing, but when it closed, I found that it had converted the first six tunes only. I attempted to do the remaining tunes as a second batch, but this time the terminal flicked open and closed again before I saw what it said, if anything.
I tried again, with six tunes, and then with two, but always with the same result: the terminal flicking open and shut.
I removed and reinstalled WinFF and ffmpeg, and this time installed codecs, but WinFF continued to do nothing (other than opening and shutting the terminal).
I had found nothing germane on the forums, and I was unsure whether this was a bug with WinFF, or Linux Mint, or whether my computer simply needed more memory, so I installed WinFF on my laptop, which is running Ubuntu 10.04 (and has 4G of memory, although only 3 are used).
Again, there was no difficulty playing the tunes in WinFF—but when I attempted to convert the same sixteen videos—WinFF did only the first nine. This time, when I attempted to do the remaining files as a second batch, it cooperated.
I installed Transmageddon, which worked the one time I have tried it, but only wants to convert one file at a time, and feels a bit limited in comparison with WinFF.
Is WinFF simply a prima donna? Or is there a fix for these hit-or-miss results? Since I eventually get results, I can't complain too much...but I'll be grateful for any help.

I suspect you are running out of /tmp disk space when the batch job is running. I had a similar problem with a different distro, compiling a large program.

To find out if this is the problem, open a command prompt, and use the 'df' command to display the /tmp file space. Some systems ( I don't know what Mint does ) mount the /tmp in ram, like a ram disk. If that runs out of space, conversion will stop. Since the same files ran on a system with much larger ram, I suspect this is the problem.

There are ways around it. You can mount the temp file system on a hard disk, instead of a ram disk. Only problem there is you have to manually remove the temporary files manually. Ram disks are self cleaning.

Run df before and during the run of Winff, and watch what happens. I have not used this program, although I have it installed now. It is just a front end for ffmpeg; a gui to make life a little easier.

I like the "temp file" solution, but I am not sure if it is a fit. I am assuming that the temp file is cleared once the operation is completed, but if I try to run WinFF a second time, it refuses to run at all, rather than blocking at the same point.
I ran the df command, and received the following result:

Filesystem 1K-blocks Used Available % Mounted on
tmpfs 151860 892 150968 1% /run

I reran the same batch of music on WinFF, and tried to rerun the df command while it was running (but it only took 3 or 4 seconds, so I might have muffed it).
The df command gave the same result, and the same result again after the fact.
WinFF stalled again after converting 6 videos correctly, and when I tried a second time refused to do anything (even with only one or two songs).
I ran the df command on my laptop, and it seemed to show an available size of 1548152 (10 times as big!) which seems huge in comparison, and leaves me wondering why it was unable to do the whole batch—although doing 9 songs was certainly better than 6.
I will keep poking away at this.
