Currently qsv (m)jpeg encoding is broken. Regression introducing by the commit(id: c1bcd3): fix async support, which requires the minimum async_depth to be 1, instead previous zero. But the default async_depth of qsv (m)jpeg encoding is still initialized (mostly) as zero. This patch also abviously improves qsv (m)jpeg encoding performance due to the default async_depth is changed to 4. Signed-off-by:

64c50c0e declared support for decomposing them but omitted to implement it; this adds an implementation. Also do the same for end-of-stream NAL units, since they are equivalent.

If we don't copy this value first, it is seen as 0 by h264_slice_header_init, due to zero-allocation of the new context, triggering an old hack that multiplied the denominator by 2 for files produced by old x264 versions, but only if more than one thread was used.
