MythPhone fix for loopback test mode

Description

The loopback test mode in mythphone is no longer working.

The avcodec_encode_video(..) call was returning -1. This was due to the pictureOut AVFrame not being initialized correctly. Specifically the pts was not initialized correctly.

The fix in the attached patch switches pictureOut to be a pointer to AVFrame and then uses avcodec_alloc_frame() to allocate and correctly initialize all the fields including pts.

I suspect this bug was revealed by one of the ffmpeg sync ups.

Updated patch v2.

Calling avcodec_get_frame_defaults() to initialize pictureOut.pts is a simpler fix for the problem.
