Transcoding for N810

So I know you guys mentioned that you'd talk about how you transcode your recordings for your N800 in a future show, but that doesn't help me now. :)

I think I've finally got the right ffmpeg command setup in a user job now, but it'd be really nice if I could also do like you mentioned and setup an rss feed so the nokia could auto download the recordings through gpodder. I'm not sure how to even start that, what do you use to set this up? Just a pointer in the right direction would help, I can fiddle with stuff from there to get it right.

btw, the ffmpeg command I'm using as a user job in case others want to know:
ffmpeg -y -i "%DIR%/%FILE%" -vcodec mpeg2video -ac 2 -s 512x288 -b 800k "/transcodes/%TITLE%%FILE%"

I'm on Mythbuntu 8.10 so you need to install libavcodec-unstripped if you want to encode xvid or mpeg2/4 video with ffmpeg, it'll replace the regular libavcodec library. I'm also using mplayer on the nokia to play videos, not the default player.

Krash,

I was doing it with PHP. I will post the script in a while. It was pretty easy to do.

I've been looking into this lately. In the past when dealing with standard def recordings I used nuvexport w/ffmpeg on the backend. That worked real well. Now I'm also recording some HD content via my Avermedia A180 DVB card. I tried nuvexport w/ffmpeg and I was not happy with the results. Video was choppy and audio was all out of sync. I looked at some of the other scripts out there and tried tablet-encode:

I was very happy with the files created from my HD digital recordings (MPEG2 and h264). I have created a user job in Myth that will let me use tablet-encode. The only negative is that it doesn't seem to honor the cutlist to remove the commercials. I'm looking into this.

Good place to start:

Apparently Nuvexport can use either ffmpeg, transcode or mencoder as a backend:

tablet-encode uses mencoder (mplayer) for the encoding.

I can do cut lists with nuvexport and it can use mencoder for the encoding. So I should be able to enable cutlists with tablet-encode. More to follow.
