openvela-robot c727fd9de4 flvdec: Check the avio_seek return value after reading a metadata packet
If the metadata packet is corrupted, flv_read_metabody can accidentally
read past the start of the next packet. If the start of the next packet
had been flushed out of the IO buffer, we would be unable to seek to
the right position (on a nonseekable stream).

Prefer to clearly error out instead of silently trying to read from a
desynced stream which will only be interpreted as garbage.

openvela-robot c83c6794f5 msvc: Properly specify dllexport for data symbols shared across dll boundaries
We currently only have exported data symbols within libavcodec, but
the concept is easy to extend to other libraries if necessary.
The attribute declaration needs to be in a private header though,
since we can't use CONFIG_SHARED in public installed headers.

AVIO context, without losing latency and performance characteristics.
