Fixes issue for me when doing transcode{}:gather: --sout-keep and subtitle
overlaying from dvbs. Otherwise keeps last subtitles on video if new channel
doesn't contain dvbs track.
also consistenty as spu_Create is called on transcode_spu_new()
Sends NULL-pict to encode when it's closing time, then encoder knows to
flush buffers and check that it has outputted all the frames.
Contains changes to x264/avcodec-module to implement that on encoder-side.
Add quick check on omxil/dirac/theora for that, so they don't crash.
And add likely-macro to x264/avcodec in check of NULL
If someone more familiar with dirac/theora/omxil encoder-modules could
check if they have buffers that need to be outputted, would be nice.
Fixes some tickets, but I failed to find any of those in trac.
The stream_out_t chain creation is modified: all modules are created by
the core (or by stream_out_duplicate) instead of being created by the
previous module.
sout_StreamChain{New,Delete} replace sout_Stream{New,Delete} to handle
modules chains instead of individual modules
sout_Stream{New,Delete} are still used by those new functions but made
static inside stream_output.c
Remove now unneeded psz_chain from struct sout_instance_t
Replace pointer to chain of next module by pointer to next module in
struct sout_stream_t
Example use:
vlc --sout-all input.mp4 --sout
"#duplicate{dst=transcode{vcodec=mp2v},select=es=0,dst=transcode,select=es=1}:std{...}"
(dst=transcode without acodec/vcodec is a hack to pass the encoded stream to
stream_out_standard without transcoding)
