  avconv: do not abort immediately if initializing hwaccel fails
Merged-by: Michael Niedermayer <michaelni@gmx.at>

exit_program() will try to free the decoders, which is not a good idea
from within get_format().
Return an error instead.

This fixes artifacts when the dimensions are exact powers of 2

So far it is only set in roq_encode_frame, but it is used in
roq_encode_end to free the coded_frame. This currently segfaults if
roq_encode_frame is not called between roq_encode_init and
roq_encode_end.

If resyncing leads to the same position as previously, it will again
lead to a resync attempt, resulting in an infinite loop.

Thus don't seek back beyond the last syncpoint.

This avoids assuming that e.g. audio samples are marked as

This allows omitting the sample flags from trun, if the default
