Store the file duration in the same timebase it arrives (i.e.
milliseconds) and only convert it to the file duration units (100ns)
when it's actually written, thus simplifying some calculations. Also,
store the duration as unsigned, since it cannot be negative.

The plugin loaded may not match the general implementation capability
wise.

It currently just calls av_init_packet(), which does not touch those
fields.

This will be useful in the following commits.

Do not pass just a bare AVFormatContext pointer around, wrap it in
struct. This will be useful in the following commits.

avprobe is not doing any decoding, so this is more correct than printing
information from a random codec implementation.

AVStream.codec is always non-NULL

Also, remove a stray line (apparently fallout from conflict resolution).

This avoids accessing NULL pointers in case of error.

The deinit function in the 'error' section will correctly free
everything.

This prefix is reserved for public functions only.

The reasoning is the same as for the corresponding qsvenc patch.

The QSV runtime expects the sync point address passed to
MFXVideoENCODE_EncodeFrameAsync() to be valid until
MFXVideoCORE_SyncOperation().

AVStream.codec is now deprecated. Allocate a separate codec context
instead.

The switch is not yet complete because the parsers and the bistream
filters do not have a new AVCodecParam-based API yet.

Open decoders first, next encoders. This makes sure that that
subtitle_header is always set properly, without relying on
avformat_find_stream_info() setting it.
