Anton Khirnov 6a13505c06 mpegvideo: move the MpegEncContext fields used from arm asm to the beginning 
This should reduce the frequency with which the offsets need to be
updated.

Anton Khirnov a61c2115fb configure: rework dxva in avconv handling 
Move the dxva check after the dependencies have been detected, make sure
the ole32 library exists.

Fixes build on non-Windows.

Anton Khirnov 1eb57e1d9b lavc: eliminate tb_unreliable() 
If framerate estimation is enabled, it makes sense to always apply it,
instead of limiting it to a few specific cases.

Anton Khirnov f9157463db lavf: do not use the parser duration for video 
The parser has no way of knowing video duration, and therefore no video
parsers set it.

Anton Khirnov 1ae8198bca avconv: always reset packet pts after decoding an audio frame 
Currently, if a decoder sets AVFrame.pts, we'd send the same timestamp
to it twice, which is wrong.

Anton Khirnov b19a5e5198 lavc: improve AVCodecContext.delay doxy 2014-04-22 07:44:40 +02:00
Anton Khirnov a4ed995cab txd: do not set the codec timebase. 
It is not supposed to be changed from outside of lavc.
Set the stream timebase and average framerate instead.

Anton Khirnov 21d8f4da91 resample: remove an unneeded context variable 2014-04-17 20:08:19 +02:00
Anton Khirnov ac976ed91e lavr: allocate the resampling buffer with a positive size 
This fixes cases where very few input samples (fewer than needed for one
output sample) are passed to lavr at the beginning.

Anton Khirnov b9dea23766 resample: fix avresample_get_delay() return value 
The correct "next" input sample is not the first sample of the
resampling buffer, but the center sample of the filter_length-sized
block at the beginning.

Anton Khirnov baeb59d89b avconv: rewrite output data size tracking 
Store a variable per OutputStream instead of globals for

2pass with multiple output streams.

Anton Khirnov e854b8f9f4 Work around broken floating point limits on some systems. 
The values of {FLT,DBL}_{MAX,MIN} macros on some systems (older musl
libc, some BSD flavours) are not exactly representable, i.e.
(double)DBL_MAX == DBL_MAX is false
This violates (at least some interpretations of) the C99 standard and
breaks code (e.g. in vf_fps) like
double f = DBL_MAX;
[...]
if (f == DBL_MAX) { // f has not been changed yet
    [....]
}

avcodec_flush_buffers() must release all internally held references
according to its documentation, for which all the threads need to be
flushed.

Anton Khirnov e0ab5078a7 lavc: do not force the emu edge flag

user ones) does not allocate edges when this flag is set, which may
