	Implement h264 SPS parsing, and use parsed values for codec initialisation.
no need to locate the start of the NAL unit from parseSPS

* it is already done in extractSPS_PPS
fix a vertical/horizontal inversion on the crop offsets
do not try to decode qualities that are too bg
AAC: parse the audio object type
make compile
adding HLSSampleSource.setForcedPlaylistType see #20
do not send ADTS headers, some devices do not support that...
rename setForcedPlaylistType() to setFallbackPlaylistType()
	Handle non-square pixel shapes.
	Remove unnecessary calculation.
do not crash if some PES packets are not aligned on TS packets boundaries
Merge branch 'feature/mikef/handle_aspect_ratio' of https://github.com/fougere-mike/ExoPlayer into fougere-mike-feature/mikef/handle_aspect_ratio
do not send the modified width/height to the MediaCodec yet
fix a buffer overflow.

* It might work but most of the time it just fails.
