avconv provides an option to set it externally and there isn't a way for
the outer demuxer to report the inner demuxer flag.
Solves a bad interaction between mpegts and x264, but requires
additional setting for the user.
Regression since 5f847bf61d.
After this commit, timestamps pushed by FFmpeg won't be relative
anymore, but absolute (based on the date/time at the beginning of the
push). This will allow seeking to work properly. Before this patch, the
seek was done, but ffm timestamps were way smallers than the absolute
requested timestamp (based on a date), so the seek was done, but to the
end of the stream (which was similar to no effect at all).
Some software does not support edit lists at all, the adobe flash
player seems to be one of these. Which results in AV sync errors when
edit lists are used to adjust AV sync.
2nd try on implementing this, the first try had various issues

We don't need to return an error if the directory already existed.
We make sure that the directory actually is properly writeable later
within ism_write_header by writing a manifest anyway.

Some HLS servers return 403 when the Range header is present. Disabling http
seekability probing prevents the header from being added.

Add an tri-state (seek, non seek, automatic detection) option to HTTP to control seekability (default: automatic).

This makes sure any buffered data is written to the segment, for
muxers that buffer up data internally (e.g. fragmented mp4).

This makes sure new inline headers are emitted when the next
packet is written. This allows segmenting mpegts without calling
write_header/write_trailer (nor freeing/reiniting the muxer)
for each segment.

Some segmented formats (such as fragmented mp4) are "bare", as in,
the segment files do not have the same headers/trailers as full normal
files of that format have.

This makes sure the muxers are set up in the way they expect
with no data left around from the previous run (which could
cause various issues including memory leaks, depending on the chaine
muxer).
This fixes memory leaks with the mpegts and flv muxers. It also
makes the usage of chained muxers correct.

With this change, the segmenter muxer doesn't rely on anything
not available/supported to libavformat external users, making
the segmenter muxer do things just like a normal segmenter
application using libavformat would do.

Before, the chained muxer reused the AVStreams array from
the outer muxer, which made it impossible to use the proper
public functions (such as av_write_frame) when calling the
chained muxer.

The timebases before where only guranteed to be 1/fps precisse
and could cause AV sync errors on low fps
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
otherwise a unexpected timebase could be choosen
that is one that is thousand times more precisse than requested
which can have sideeffects.

The new fields are only printed when they differ from their defaults

This might not be needed at the moment, but it's good practice to
pass it to all chained AVFormatContexts, if it would happen to be
used there at a later point.

While a 25 fps stream can in general store frame durations in 1/25
units, this is not true for the timestamps. For example a 25fps
and a 25000/1001 fps stream when they are stored together might have
a matching 0 timestamp point but when for example a chapter from
this is cut the new start is no longer aligned. The issue gets
MUCH worse when the streams are lower fps, like 1 or 2 fps.
This commit thus makes the muxer choose a multiple of the
framerate as timebase that is at least about 20 micro seconds precise
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
With this, when we use a finer timebase than neccessary to store
durations the demuxer still knows what the original timebase was.
