demuxer->filepos contains the byte offset of the last read packet. This
is so that the player can estimate the current playback position, if no
proper timestamps are available. Simplify it to use demux_packet->pos in
the generic demuxer code, instead of bothering every demuxer
implementation about it.
(Note that this is still a bit incorrect: it relfects the position of
the last packet read by the demuxer, not that returned to the user. But
that was already broken, and is not that trivial to fix.)
Using -demuxer mpegts -correct-pts triggered the assertion in
ds_get_packet2(). This is not surprising, because the correct-pts code
was changed to accept _complete_ packets, while all the old demuxers
(including the mpegts demuxer) require you to use "partial" packet
reads, together with the video_read_frame(). (That function actually
parses video frames, so fragments of the original "packets" can be fed
to the decoder.)
However, it returns out demux_ts packet's are mostly useable. demux_ts
still adds an offset (i.e. ds->buffer_pos != 0) to the packets when
calling internal parser functions, such as in parse_es.c. While this is
unclean design due to mplayer's old video demuxing/decoding path, it can
be easily be made work by modifying the packet as returned by
ds_get_packet2(). We also have to change the packet freeing code, as
demux_packet->buffer doesn't have to point to the start of the memory
allocation anymore.
MPlayer handles this "correctly" because it doesn't have a function that
reads a complete packet.
Tis drops the silly lib prefixes, and attempts to organize the tree in
a more logical way. Make the top-level directory less cluttered as
well.
Renames the following directories:
libaf -> audio/filter
libao2 -> audio/out
libvo -> video/out
libmpdemux -> demux
Split libmpcodecs:
vf* -> video/filter
vd*, dec_video.* -> video/decode
mp_image*, img_format*, ... -> video/
ad*, dec_audio.* -> audio/decode
libaf/format.* is moved to audio/ - this is similar to how mp_image.*
is located in video/.
Move most top-level .c/.h files to core. (talloc.c/.h is left on top-
level, because it's external.) Park some of the more annoying files
in compat/. Some of these are relicts from the time mplayer used
ffmpeg internals.
sub/ is not split, because it's too much of a mess (subtitle code is
mixed with OSD display and rendering).
Maybe the organization of core is not ideal: it mixes playback core
(like mplayer.c) and utility helpers (like bstr.c/h). Should the need
arise, the playback core will be moved somewhere else, while core
contains all helper and common code.
