Treat Recorded Tv as a Special Case
Hi
I am currently evaluating Mezzmo and I shall definitely be purchasing it! I had thought DLNA to be a rather useless feature of my Tv but not any more...
My primary interest in Mezzmo is for the viewing of Recorded TV from my media centre PC in a second room. The PC runs Windows 7 and thus records using Windows Media Center in wtv format. The TV is a Pansonic Viera 2011 model.
I woud like to suggest that you consider treating Recorded Tv as a special case separate from Video with different configuration options for the following reasons:
Recorded Tv is much more dynamic as recordings are added and deleted than say a relatively static music library. Also the number of files involved is likely to be small say < 100. Media PC are often set to only wake up to perform recordings and when needed for playback. I find the current library update schedule in Mezzmo a little limiting as it is at most once per day and if the PC is asleep doesn't actually run. It seems to me that Record Tv really needs a very much much more frequent directory scan looking for adds and deletes that is perhaps active the whole time that the PC is running.
Thumbnails. Well I was going to mention that on H264 video that the image is often just a grey swirl but I see that you have added a -ss 3 parameter to ffmpeg in the latest version that resolves this - so thanks! On a separate issue I normally set TV recordings to start a few minutes early as some channels do occasionally start early and clocks can drift out of synchronisation. Unfortunately this means that the thumbnails that I see are usually of the previous program. I would like to be able to set a thumbnail initial offset for recorded tv to match the PC recording start padding.
Recorded Tv meta data. I only know about Window Media Centre. The title delivered to the DLNA renderer is the file name and the date shown is I think the file system modified date (which is not necessarily the date of the recording if its been part played by media center and the position updated).
Copuld you consider parsing the names of Wtv files in oder to show the tite and recording date?
If the file name is 'The Drowning Pool_BBC ONE_2010_08_24_23_30_00.wtv'- then the data before the first underscore is the title whilst the date and time of the recording follow the channel.
Alternatively ffmpeg reports all the embedded meta data -e.g for the recording above there is a title and genre - see below.
