The commits eac4324bfb and
cd8211527e renamed the examples, but the
targets were not updated. Hence, the builds are missing -lm.

Stop claiming the argument is always a floating point number, which
* confuses floating point and decimal numbers
* is not always true even accounting for the above point
Read the timebase from FrameData rather than the input stream. This
should fix#10393 and generally be more reliable.
Replace the use of '-1' to indicate demuxing timebase with the string
'demux'. Also allow to request filter timebase with
'-enc_time_base filter'.
This decoding flag makes decoders drop all frames after a parameter
change, but what exactly constitutes a parameter change is not well
defined and will typically depend on the exact use case.
This functionality then does not belong in libavcodec, but rather in
user code
Useful for discovering bugs that depend on a specific thread count.
Use like THREADS=randomX for a random thread count from 1 to X, with
X=16 when not specified. Note that the thread count is different for
every test.
Uses the existing code for av_get_random_seed() to return a buffer with
cryptographically secure random data, or an error if none could be generated.

Support decoding and embedding VANC packets delivered via SMPTE 2038
into the SDI output. We leverage an intermediate queue because
data packets are announced separately from video but we need to embed
the data into the video frame when it is output.
Note that this patch has some additional abstraction for data
streams in general as opposed to just SMPTE 2038 packets. This is
because subsequent patches will introduce support for other
data codecs.
Thanks to Marton Balint for review/feedback.

- text is now shaped using libharfbuz
- glyphs position is now accurate to 1/4 pixel in both directions
- the default line height is now the one defined in the font
Adds libharfbuzz dependency.
I've been sitting on this for 3 1/2 years now(!), and I finally got
around to fixing the loose ends and convincing myself that it was
correct. It follows the same basic structure as yadif_cuda, including
leaving out the edge handling, to avoid expensive branching.
The contents of this field are not defined for decoding. Use
pkt_timebase, which is the timebase of demuxed packets.
Drop a tautological av_packet_rescale_ts() call, as the stream and
decoder timebases are the same.
Added prerequisites that must be met before providing support for the MPEG-5 EVC codec
- Added new entry to codec IDs list
- Added new entry to the codec descriptor list
- Bumped libavcodec minor version
- Added profiles for EVC codec
