avconv: only retry decoding on actual decoding errors
...
Errors during decoding are currently considered non-fatal and do not
terminate transcoding, so even if parts of the data are corrupted, the
rest may be decodable.
However, that should apply only to the actual decoding calls, not to the
failures elsewhere (e.g. configuring filters).

avconv: make sure the filtergraph is freed on init failure
...
The filtergraph's existence is used in several places to mean that the
filtergraph is fully configured. This causes problems if it's allocated,
but the initialization fails (e.g. if a non-existent filter is
specified).

lavf: fix usage of AVIOContext.seekable

It is supposed to be a flag. The only currently defined value is
AVIO_SEEKABLE_NORMAL, but other ones may be added in the future.
However all the current lavf code treats this field as a bool (mainly
for historical reasons).
Change all those cases to properly check for AVIO_SEEKABLE_NORMAL.

vaapi_encode: Sync to input surface rather than output
...
While outwardly bizarre, this change makes the behaviour consistent
with other VAAPI encoders which sync to the encode /input/ picture in
order to wait for /output/ from the encoder. It is not harmful on
i965 (because synchronisation already happens in vaRenderPicture(),
so it has no effect there), and it allows the encoder to work on
mesa/gallium which assumes this behaviour.
