It's supposed to be called only from (de)muxers.
|
|
Specifically av_update_cur_dts(), av_seek_frame_binary() and
av_gen_search().
They are not supposed to be called outside lavf.
|
|
Manual replacements are done in this commit.
In many cases, the id is some constant made up number (e.g. 0 for video
and 1 for audio), which is then not used in the demuxer for anything.
Those ids are removed.

This patch also introduces CODEC_ID_CELT.

Between ogg_save() and ogg_restore() calls, the number of streams
could have been reduced.

Specifically crafted samples can reinit ogg->streams[] while
reading samples, and thus we should not cache old pointers since
these may no longer be valid.

Fixes Bugzilla #11.

ogg_save() copies streams[], but doesn't keep track of free()'ed
struct members. Thus, if in between a call to ogg_save() and
ogg_restore(), streams[].private was free()'ed, this would result
in a double free -> crash, which happened when e.g. playing small
chained ogg fragments.

This avoids the creation of a new AVStream instead of replacing it when
a stream reset occurs (track change with some webradios for example).

Use it instead of url_is_streamed and AVIOContext.is_streamed.
|
|
AVIOContext.eof_reached should be used directly instead.

In the name of consistency:
get_byte -> avio_r8
get_<type> -> avio_r<type>
get_buffer -> avio_read
get_partial_buffer will be made private later
get_strz is left out becase I want to change it later to return
something useful.

Currently (since the data_offset fix) the ogg demuxer assumes that
after the first non-header packets in any stream no more header packets
will follow.
This is not guaranteed, so change the code back again to wait until it
has finished the headers for all streams before returning from ogg_get_headers.
This fixes issue 2428.

This also lists the objects from those two libraries as internal (by adding
the ff_ prefix) so that they can then be hidden via linker scripts.

This fixes some old ogm files that had the 3rd vorbis header after a data
packet in another stream. This is invalid in ogg, but this change shouldn't
affect the behaviour of any valid file.

This takes into account whether the granule defines the start or end times
of packets, and sets the correct file offset of the associated page.
