Resume AVI files

[GBPVRkid]

It would be fantastic if one can resume AVI files when using FFMPEG

You can already resume AVI files, just like any other file...unless you're using the MVP, which requires transcoding the file.

That's what I meant...when using the MVP..

Just a wish...I know over at SageTV world, they also trancode the avi files using FFMPEG and someone was able to add the resume feature

I've been thinking about this one for a while...

I have noticed that a temporary file MVP...*.mpg gets created, and sometimes after a MVP reboot or other error the file remains afterwards. So somewhere along the line during normal operation the file gets deleted. I have been trying to think of a way to "trick" windows into not deleting the file.

I use transcoding.bat, I have been thinking of some way to do something in there. If it were Unix, I could maybe create a link and trick whatever is deleting the MVP..*.mpg file to just deleting the link. Is there something like that for Windows? Setting permissions on the file to read only?

I was also thinking of creating a mini-daemon that monitors for MVP*.mpg files and copies them on the fly so when the MVP*.mpg gets deleted I can go to the backup. I think this would be less costly than simultaneously transcoding a backup.

Sometimes I manually do the transcoding to mpg to avoid the aggrevation of the occastional reboot or other interruption.


The most frustrating thing is when the file has completely transcoded, but for whatever reason you have to stop watching. Then to get back to that part in the show you have to sit and wait for the transcoding to catch up. That scores a big negative on the WAF meter.

I apologise on beforehand, I am not very familiar with this.
But in the FFMPEG-doc (http://ffmpeg.sourceforge.net/ffmpeg-doc.html#SEC7) it seems that you can give the location from where to start transcoding, so when GBPVR remembers where it stopped, it should be able to start from there (or a little earlier) again. Forgive me if I missed something completely

Doesn't the system transcode to a temp file and the MVP pull data when it needs to? So the transcode point could be well into the future of what you are watching??

I did look into doing something like this a while ago, but unfortuntaly if you tell ffmpeg to start transcoding 30 minutes in to the file (-ss 00:30:00) then it reads and processes the whole file up to that point before it starts producing the new file. Its faster than real time, but still painfully slow. The result is, it doesnt start producing the newly transcoded file for several minutes. No one wants to wait several minutes each time they press the skip key, or when they try to resume.

If I had been able to find away around this, you would probably have this feature by now.
