#7053 new enhancement
bitpacked codec too limited

Description
I am currently using ffplay to check RTP streams generated by third-party programs (along with their SDP files)
Currently, ffplay can only decode YUV422 8 and 10 bits, sent to the bitpacked codec.
However the RFC4175 (about RTP streams) submits far more formats :
YUV422 12bits,
YUV422 16bits,
RGB888,
RGB101010,
RGB121212, (with variants BGR/RGBA...)
it would be great if rtpdec_4175.c and bitpacked.c could be updated to handle those formats (that must be decoded somewhere else in libavformat with another codepath linked to another codec)

I have attached a program I made to genenerate such streams and their sdp files.
Currently it can generate RGB888, YUV422-8b, YUV422-10b, YUV422-12b, YUV422-14b, YUV422-16b
It can be compiled under Windows or Linux with a c++-11 compliant compiler

The rtp streams can be displayed by ffplay (currently only with YUV422-8b or YUV422-10b) with such a command :
ffplay -protocol_whitelist "file,rtp,udp" -strict -2 -i rtpgenerator.sdp

I have added a patch that adds 12, 14, 16 bit depths variations to YUV422 packed.

Please send your patch to the FFmpeg development mailing list where it can be reviewed.
Where can I find sample streams?
