The new name is more meaningful in that context.

Keeping the set options in the context when the component is still used
can be useful for debugging purposes.

Avoid to fill the same picture again and again with the same content.

Optimize computation, and provides an example for the use of the
AV_PERM_REUSE permission flag.

The values are listed if setting them fails.
Using "-profile help" or "-profile list" have that effect.
Similar to 3aba391f.
Suggested by "rogerdpack" in trac ticket #1529.

AVPacket.duration is mostly made up and thus completely useless, this is
especially true for video streams.
Therefore use dts difference for framerate estimation and
the max_analyze_duration check.

The asyncts test now needs -analyzeduration, because the default is 5
seconds and the audio stream in the sample appears at ~10 seconds.

Useful in cases where a significant analyzeduration is
still needed, while minimizing buffering before output.

An example is processing low-latency streams where all
media types won't necessarily come in if the
analyzeduration is small.

MMX-enabled systems by default use some dsputil functions differing
from the C versions.  Adding these flags ensures accurate ones are
used everywhere.

This allows us to unconditionally set the cglobal num_args
parameter to a bigger value, thus making writing yasm code
even easier than before.
Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

Without this, cglobal will expand "z" to "zh" to access the high byte
in a register's word, which causes a name collision with the ZH(x) macro
further up in this file.

concat_in.pts starts at 0 for each segment, so the duration
of the silence was too long, except at the first stitch.

The voice register functions return the same voice structure
upon multiple registration. It causes us two problems:

If we delete a voice without deregistering it, it leaves
a dangling pointer inside the library.

If we delete or unregister a voice at uninit, it may still
be in use by another instance of the filter.

The second problem is solved by keeping an usage counter inside
asrc_flite. This is not thread-safe, but neither is flite itself.

Don't invent a bogus EIO error.

The code now doesn't check for ret == 0, but that check is redundant,
av_get_packet() never returns 0.
