Pause/Resume encoding on I/O Error

[balagemayrag]

Today it happened to me twice that FFMpeg stopped encoding a HD resolution video because there was no more space left on the device. Now I have deleted some of unnecessary files and there is enough space but it really gave me a headache that I needed to redo the whole conversion from start. I'm talking about a conversion that takes 8-10 hours. The partially-converted output file stayed there but I have found no adequate ways or howtos about resuming an interrupted conversion.

I would like to request a simple feature: If there is a write error to the disk, pause the encoding, let the user do the troubleshooting and then let them resume.

This would be really useful in all cases of I/O errors, for example a USB hub doing a reset then interrupts all the devices plugged into it. Same happens.
