Status of Trunk?

[Jack Deslippe]

Hi,

I am hoping to get involved with this project - particularly trying to improve some of the UI elements and features for tablets.  I have developed a few android apps now on the market (search jdeslip or Droidian Apps) - but I don't know much about MythTV internals etc...

I checked out the latest source, built it, and tested it on my xoom.  Unfortunately, I couldn't get anything to stream to device (I had some success on the 0.4.4 version, but not on trunk).  Is this expected. 

Here is my mdd.log:

Is this expected on trunk?  Basically, I would like to test things to help create a better experience for Android tablets over a LAN.  There are some immediate changes to the UI I could make, but I also want to work on making sure a good bitrate / resolution options are available as well.  This is difficult given that streaming seems to be broken.

Hopefully fixed by http://code.google.com/p/mythdroid/source/detail?r=393.

Some additional bitrate options were on my todo list so that would be great. With regard to resolution, MythDroid requests a resolution equal to the screen dimensions, however mdd currently disregards this. The reason for this is that an upscale at encode time is expensive; if we stream a SD resolution program to a tablet the backend incurs the extra expense of scaling the video but, more importantly, has to do an h264 encode of many more pixels. Only very fast multi-core backends will be able to keep up. Conversely, scaling at display time is cheap (done in hardware) and we therefore do not alter the resolution at encode time. What we probably should do is check the dimensions received from MythDroid and turn on scaling if the requested dimensions are smaller than that of the source video - there's no point spending cycles on encoding a resolution that's too big.

Looking forward to seeing what you come up with.

Regards,
