e8565d21c2 avformat/flvenc: check that the codec_tag fits in the available bits 
flags is later written with avio_w8 and if it doesn't fit in one byte it
triggers an av_assert2.

4f6cd883f0 rtpenc: Don't set max_frames_per_packet based on the packet frame size or frame rate 
Instead check the timestamps while muxing, to avoid buffering a
too long timestamp range into one single packet.

This makes the AMR and AAC packetization slightly less efficient,
since we set a possibly unnecessarily high max_frames_per_packet.
(These packetizers end up doing a memmove of the TOC bytes if
sending a packet before max_frames_per_packet is achieved, and
we end up setting max_frames_per_packet to a value that should
be high enough for most uses.)

All packetizers that use max_frames_per_packet now set it either
to a default value, or to a value calculated based on other
parameters, so none of them rely on the previous default setting.

For iLBC, copy one frame at a time, to allow checking the timestamp
range for each of them - basically doing potentially multiple
loops to simplify the code instead of trying to calculate the
number of frames to buffer while honoring s1->max_delay.

This is in preparation for reducing the coupling between libavformat
and libavcodec, by not having the muxers use the encoder field
frame_size (which may not be available during e.g. stream copy).

bde2bba45c rtpenc: Restructure if statements in packetizers to simplify adding more conditions 
Factorize out the s->num_frames check at the start of the if statements,
simplifying adding more alternative causes for sending the buffered

f8c01257f9 rtpenc: Always do the default initialization regardless of codecs 
This avoids having to jump to the defaultcase in the switch. Manually
override the stream time base back to 90 kHz for the few audio codecs
that don't use the sample rate as time base (mp2, mp3).

9856395344 rtpenc_aac: Fix sending fragmented frames 
After sending a fragmented frame, len (s->buf_ptr - s->buf) isn't
zero, while s->num_frames is zero as intended. Using s->num_frames
makes it work as intended, and is less convoluted than keeping track
of (resetting) s->buf_ptr.

This avoids sending stray data after sending a fragmented aac packet.
