4601735e51 Add support for AAC audio codec 
Add option --audio-codec=aac.

13a3395a33 Disable audio on initialization error 
By default, audio is enabled (--no-audio must be explicitly passed to
disable it).

However, some devices may not support audio capture (typically devices
below Android 11, or Android 11 when the shell application is not
foreground on start).

In that case, make the server notify the client to dynamically disable
audio forwarding so that it does not wait indefinitely for an audio
stream.

Also disable audio on unknown codec or missing decoder on the
client-side, for the same reasons.

609b098a97 Do not merge config audio packets 
For video streams (at least H.264 and H.265), the config packet
containing SPS/PPS must be prepended to the next packet (the following
keyframe).

For audio streams (at least OPUS), they must not be merged.

e02f30f895 Remove unnecessary error logs 
When a call to a packet or frame sink fails, do not log the error on the
caller side: either the "failure" is expected (explicitly stopped) or it
must be logged by the packet or frame sink implementation.

680ddf64be Fix demuxer error message 
Now that there are several possible codecs, do not hardcode H.264 in the
error message.

49eb326ce9 Extract packet merging 
Config packets must be prepended to the next media packet. Extract the
logic to a new sc_packet_merger helper to simplify the demuxer code.

730eb1086a Properly report demuxer errors 
All demuxer errors were reported as "device disconnected", even if the
failure was not related to device socket read.

953edfd1df Split codec_id reading 
Receive codec id and convert it to AVCodecID separately.

This will allow the caller to distinguish between EOS and unknown codec
id.

bf8696d02e Avoid unnecessary copy on config packets demuxing 
Use av_packet_ref() to reference the packet without copy.

This also simplifies the logic, by making the "offset" variable and the
memcpy() call local to the if-block.

e3c2398aa2 Store packet flags in PTS most significant bits 
A special PTS value was used to encode a config packet.

To prepare for adding more flags, use the most significant bits of the
PTS field to store flags.

61b6324ee9 Remove LOGC()

LOGE().

Moreover, enum sc_log_level has no "critical" log level.

7dec225ceb Rename stream to sc_demuxer 
For consistency with recorder and decoder, name the component which
demuxes a "demuxer".

And add the missing sc_ prefix.
