828d3b4432 doc/examples/transcode: set packet timebase for decoding 
It is recommended for callers to set it, though not required.

da23151eaf avformat/oggparseflac: use the GetByteContext API 
All but one read are byte aligned, so there's no point in using the
GetBitContext API.

ba2c791627 fftools/ffmpeg_filter: do not flush encoders on parameter change

106167374c fftools/ffmpeg_mux: flush bsfs immediately on exceeding recoding time 
Current code marks the output stream as finished and waits for a flush
packet, but that is both unnecessary and suspect, as in theory nothing
should be sent to a finished stream - not even flush packets.

2262df5e8a fftools/ffmpeg_filter: drop unreachable code 
Filtergraphs with no inputs are initialized as soon as all their outputs
are bound, so this code should not be reachable.

f3e0a83e8e fftools/ffmpeg_enc: stop configuring filters from encoder flush 
There is no way for a filtergraph to have all input parameters, yet not
be configured, so this code should not be reachable.

f8abab673c fftools/ffmpeg: move sub2video handling to ffmpeg_filter 
Make all relevant state per-filtergraph input, rather than per-input
stream. Refactor the code to make it work and avoid leaking memory when
a single subtitle stream is sent to multiple filters.

20cacfe493 fftools/ffmpeg: rework setting sub2video parameters 
Set them in ifilter_parameters_from_dec(), similarly to audio/video
streams. This reduces the extent to which sub2video filters need to be
treated specially.

ea5c39cef6 fftools/ffmpeg: tweak sub2video_heartbeat() arguments 
This function should not take an InputStream, as it only uses it to get
the InputFile and the timebase. Pass those directly instead and avoid
confusion over dealing with multiple InputStreams.

a6d67b11f5 fftools/ffmpeg_filter: move sub2video subtitle queue to InputFilterPriv 
This queue should be associated with a specific filtergraph input - if
a subtitle stream is sent to multiple filters then each should have its
own queue.

5d530e3a72 fftools/ffmpeg_dec: move sub2video submission to ffmpeg_filter 
This code is a sub2video analogue of ifilter_send_frame(), so it
properly belongs to the filtering code.

Note that using sub2video with more than one target for a given input
subtitle stream is currently broken and this commit does not change
that. It will be addressed in following commits.

ad4efb9158 fftools/ffmpeg_filter: try to configure filtergraphs earlier 
When the filtergraph has no inputs, it can be configured immediately
when all its outputs are bound to output streams. This will simplify
treating some corner cases.

dc5864a00c fftools/ffmpeg_filter: create Input/OutputFilters together with FilterGraph

da7ae627e1 fftools/ffmpeg_filter: always pass graph description to fg_create() 
Currently NULL would be passed for simple filtergraphs, which would
make the filter code extract the graph description from the output
stream when needed. This is unnecessarily convoluted.

859c34706d avdevice/decklink_common: Convert to using avpriv_packet_list functions 
The existing DecklinkQueue implementation was using the PacketList
structure but wasn't using the standard avpriv_packet_list_get and
avpriv_packet_list_put functions.  Convert to using them so we
eliminate the duplicate logic, per Marton Balint's suggestion.

Updated to reflect feedback from Marton Balint provided on 05/11/23.

a9042db1d3 avformat/oggparseflac: check init_get_bits' result 
Check init_get_bits' result for NULL, to avoid dereferencing a NULL
pointer later (CWE-476).
Without this, a segfault happens when trying to decode a handcrafted
ogg-flac file with an absurdly long (e.g. 268435455 bytes) ogg header.
