If an audio stream is present, the Sega FILM muxer checks for its
compability with the container during init, so that the very same check
needn't be repeated during writing the trailer.
Essentially the same is true for the presence of a video stream: It has
already been checked during init. Furthermore, after the check for the
presence of a video stream succeeded, a pointer is set to point to the
video stream. Yet said pointer (which was NULL before) will be
derefenced anyway regardless of the result of the check. Coverity thus
complained about this in CID 1434155 and removing this pointless check
will also fix this issue.

Commit 36e156bef0 ("avformat/spdifenc: fix handling of large TrueHD
frame") added an obviously incorrect bitshift that caused incorrect
samples-per-frame calculation for TrueHD streams over 48kHz.
Fix that.
The TrueHD IEC 61937 encapsulation code uses a very naive method of
always inserting 24 TrueHD frames evenly in a MAT frame. This does not
work for larger frames as they may exceed the size of 1/24th of a MAT
frame.
To fix that, use the input_timing field in the TrueHD frame to determine
the proper position of the TrueHD frame in the MAT frame. That field is
basically a dts field, telling the time to feed this frame to the
decoder in sample count units.
This can cause a TrueHD frame to be split between two MAT frames, so a
second concatenation hd_buf is added, alternating with the first buffer.
Large frames are preceded by smaller frames that have input_timing
values that cause the frames to be sent out faster than the nominal rate
(i.e. increasing decoder latency, long decoder buffer), allowing the
larger frames to then be sent out slower than the nominal rate as the
decoder has enough data buffered to keep it busy.
This is preparation for adding a second hd_buf in a followup commit.
Also, slightly improve the comments for hd_buf_x members to clarify
which ones are actually used and kept up-to-date depending on which
codec is being muxed.
wtvfile_read_packet did not abide by the requirements of an
AVIOContext's read_packet-function: If it did not read anything,
it returned zero, which currently leads to a warning in read_packet_wrapper
in aviobuf.c. Said warning will be an av_assert2 as soon as
FF_API_OLD_AVIO_EOF_0 is zero (probably the next major version bump).
So instead forward the error code from the underlying protocol.
This error/assert is triggered in the wtv-demux FATE test.
