It's done when loading the decoder/packetizer.

This avoids probing video or SPU decoders for audio format and vice-
versa.

Will only workaround the bug for those 7.1 mappings

FAAD can't properly map channels with instance > 2.
This will fix it at least for the FDK setup.

Most blocks contains aligned samples.

Causes out of sync, frame dropping.

Use only one callback for every decoder types:

int (*pf_decode)(decoder_t *, block_t *p_block);

There is now only one way to send output frames/blocks from a decoder module:
using decoder_QueueVideo(), decoder_QueueAudio() and decoder_QueueSub()
functions.

This fixes transcoding not receiving any output when a decoder used
decoder_Queue*() function.

The pf_packetize callback is kept unchanged. A packetizer shouldn't be
asynchronous at all (and this simplify the locking for decoder core).

The pf_decode callback returns, for now, only one value: SUCCESS. This will
allow a module to send more status.

Decoder modules are now responsible for calling decoder_UpdateAudioFormat()
before decoder_NewAudioBuffer().

In a lot of modules, decoder_UpdateAudioFormat() could be called in a better
place. Just after dec->fmt_out is updated for example.

For now, a lot of decoder/packetizer are also flushing on
BLOCK_FLAG_DISCONTINUITY flag. Some others are also flushing on
BLOCK_FLAG_CORRUPTED flag (omxil, videotoolbox, avcodec audio).

This patch doesn't change the current behavior.
But maybe we shouldn't flush anymore on DISCONTINUOUS/CORRUPTED.

Most of the cases it's enought just to set pts so codec resyncs itself.
Also flushing on discontinue isn't good idea.

This reverts commit 5e36cb2c.

This reverts commit 48a867c7.

Revert for futher checking

If blocks are marked BLOCK_FLAG_DISCONTINUITY then do not drop them,
unless BLOCK_FLAGS_CORRUPTED is set. Instead flush old blocks from decoder
queue and restart at this new stream access point (new timeline).

When needed (fmt->b_packetized == false), create a packetizer before creating a
decoder. The fmt_in of the decoder is copied either from the fmt_out of the
packetizer, or from the fmt of CreateDecoder.

output pts/length is computed from input block pts.
If sample rate is wrong, all timings are borked.
Try to use the declared sample rate if possible.

If source has wrong sample rate
