alsta: Hi Eddy, have been watching the progress of the DVB-T handbrake encoding with interest as an Freeview EyeTV to AppleTV media center is exactly what I am planning.
Fantastic to have someone from NZ so involved in the development
Couple of questions,
1. how long did the encode take with the SVN version? (say benchmarked against a 2.8Ghz iMac?)I only did a TV3 1080i AVC/AC-3 stream, because EyeTV is pathetic at those, and HandBrake can't do AAC-LATM at the moment. I found it to be faster than EyeTV but not by a huge amount. What was better though was the quality, heaps better than what EyeTV/QT was putting out - plus it was nice having the AC3 pass through.Speed will be an issue - on a Mac Pro I was not getting 25fps for 1080i to 720p conversions (either with HB or QT), and so the 6 o'clock news wouldn't be ready until 8:30 - which is a tad late (assuming channel one was 1080i - which it isn't).When I get some time I want to look at improving the speed - fewer frame copies would help.2. Do you have a feeling for when a release version is likely to happen, i.e. weeks or months?There are some issues with AAC-LATM, not really technical ones. We are trying to figure out where it ought to be implemented. LATM allows multiplexing audio streams into a single AAC stream. However DVB only ever puts one stream in there. So should the feature be implemented at the codec level, or the muxer level? It's sort of inbetween the two (a bit like TCP/IP and the ISO stack with networking). If it is implemented in the codec, then we need to add one to ffmpeg to do this. If it is implemented in the demuxer, which for HB is within the HB code.I ffmpeg/HB developer is looking at it, so I've backed off for a while to see what happens.And anyway, the newest EyeTV release is really bad - useless in fact, it is crashing and putting out crap output. So elgato need to fix that before HB can really do anything useful.Cheers, Ed.
