Fixes build errors with nasm introduced in 6f40e9f0 for stack
memory alignment. Noticed by BugMaster.

The FLV muxer tries to update the header in write_trailer, which is
impossible if writing to a pipe or network stream. Don't write header
data if seek to header fails.

Consistent with the image2 muxer.

Factorize.

This requires to move the avcodec_default_free_buffers() call to
ff_MPV_common_end() since otherwise delayed pictures would get freed
during a size change.

Direct rendering capable decoders call get_buffer() which will set the
frame parameters.

Prevents frames with wrong parameters when a decoder outputs delayed
frames after a resolution or pixel format change.

Fixes a crash in the fuzzed sample sample_varPAR.avi_s26638 with
alternating bit depths.

Note the time base for the option. Add an additional example description.

The max_comp option is supposed to limit maximum compensation, but
currently the clipped value is not actually used.

Currently it will do padding, but it does not properly handle
start-of-stream trimming as documented.
