the loglevel command line option.

Make the loglevel option help message more clear, since the option
argument is shown as a single token, and make the whole message better
aligned with the other help messages.

the wrong place, causing an empty packet to be read before EOF was
detected and the eof detection is already now handled by av_get_packet anyway.

in the raw demuxers.
Also remove special handling of 0-size reads, if they are due to an error/eof,
these are already converted to the appropriate error by get_buffer.


git-svn-id: file:///var/local/repositories/ffmpeg/trunk@20137 9553f0bf-9b14-0410-a0b8-cfaf0461ba5b

The au and aiff demuxers would always return an empty packet before
detecting EOF, this is now fixed with av_get_packet etc. returning EOF.


git-svn-id: file:///var/local/repositories/ffmpeg/trunk@20136 9553f0bf-9b14-0410-a0b8-cfaf0461ba5b

appropriate if it couldn't read any data at all.
This should make handling of EOF and error simpler or make it work right without
extra code in a few place (e.g. raw demuxer).

This is consistent with other demuxers and also fixes a memleak (memory
allocated for partial frame data was leaked).

This fixes the API breakage introduced by the check that avctx codec id and type
match the opened codec and should make (almost?) all applications work again.

undefined shift behaviour.
Document this, fix the assert and add a put_bits32 to handle writing 32
bits and use that where necessary.
