fmtconvert: Add a new method, int32_to_float_fmul_array8 · 31c6f6f6

Ben Avison authored Jul 15, 2013

This is similar to int32_to_float_fmul_scalar, but
loads a new scalar multiplier every 8 input samples.
This enables the use of much larger input arrays, which
is important for pipelining on some CPUs (such as
ARMv6).

avfilter/REDUCE_FORMATS: fix bug that ended reducing too early · 51691111

Michael Niedermayer authored Jul 21, 2013

Prior to this it was possible that format reduction was ended
before it fully propagated leading to failure later in picking
formats.
No testcase with unmodified source exists, the case was reproduced
with less aggressive list merging though.

Revert "avformat/utils: Close codec context since it is allocated by avformat_new_stream in refrence to ticket 2716"

This causes a race condition with VLC. Its plausible that other
applications also would have races with it and its just fixing a memleak when
the user application forgets to free the codec. It causes more
problems than it solves in its current form, thus the revert.
Better solutions are welcome

This reverts commit 0f229f9b.
