/**

|
|
* @file decode-avi-player-full.ino
|
||
|
|
* @brief Same pipeline/test file as decode-avi-player.ino, but via
|
||
|
|
* AudioTools/Video/VideoPlayerFull.h (a VideoPlayer subclass that
|
||
|
|
* pre-registers H264Decoder/MJPEGDecoder/MPGDecoder and
|
||
|
|
* MP3DecoderHelix/AACDecoderHelix/MP2Decoder itself - see its own class
|
||
|
|
* comment) instead of registering the codecs by hand. VideoPlayerFull
|
||
|
|
* pre-registers no container demuxer of its own, so this still supplies
|
||
|
|
* one explicitly - a MultiVideoDemuxerFull (Video/MultiVideoDemuxerFull.h)
|
||
|
|
* rather than a plain DemuxerAVI, to demonstrate the "any container
|
||
|
|
* format just works too" pattern VideoPlayerFull's own class comment
|
||
|
|
* recommends (this file happens to only ever feed it an AVI, but the same
|
||
|
|
* player would equally auto-detect an MP4/MPG file).
|
||
|
|
*
|
||
|
|
* To build & run:
|
||
|
|
* - mkdir build && cd build && cmake .. && make
|
||
|
|
* - ./decode-avi-player-full
