Anton Khirnov 6599b087de buffersrc: fix a typo. 
Vertical shift is log2_chroma_h, not log2_chroma_w.
 2013-03-19 11:12:17 +01:00
Anton Khirnov 2c328a9079 pixdesc: add a function for counting planes in a pixel format. 2013-03-19 11:12:17 +01:00
Anton Khirnov 1516bf7af1 lavc: update the doxy for avcodec_decode_{video,audio} wtih refcounting. 2013-03-19 11:12:17 +01:00
Anton Khirnov c977039e58 lavc, lavfi: fix counting number of planes in AVBufferRef wrappers 
Number of planes is not always equal to the number of components even
for formats marked with PIX_FMT_PLANAR -- e.g. NV12 has three components
in two planes.
 2013-03-19 11:12:17 +01:00
Anton Khirnov e5c32d6da7 avplay: remove the -debug option. 
It just shadows the corresponding AVOption and prevents using named
constants.
 2013-03-19 11:12:13 +01:00
Anton Khirnov 3cd93cc7b8 Revert "asfenc: return error on negative timestamp" 
This reverts commit d1bec33b46, it breaks
FATE.
 2013-03-19 11:04:55 +01:00
Anton Khirnov 358628074c print_options: do not generate docs for options without enc or dec flags 
Those are not usable from the avtools, so mentioning them in the
manpages just confuses the reader.
 2013-03-18 15:36:25 +01:00
Anton Khirnov ce0124acac mpeg12: do not fail on zero dimensions in the sequence header. 
The total frame size is a combination of the 12 bits in the sequence
header and 2 more bits in the the sequence extension. While the
specification explicitly forbids the dimensions from the sequence header
from being 0 (thus ruling out multiples of 4096), such videos
apparrently exist in the wild so we should attempt to decode them.

Based on a patch by Michael Niedermayer <michaelni@gmx.at>

Fixes Bug 416.
 2013-03-18 15:36:10 +01:00
Anton Khirnov 6552808014 lavc,lavfi: fix calculating the plane size in the AVBufferRef wrappers 
It is supposed to be height * linesize, not width * linesize.
Thanks to Hendrik Leppkes for pointing out the bug.
 2013-03-17 09:10:04 +01:00
Anton Khirnov 4750b05d67 af_join: do not leak input frames. 2013-03-16 05:37:01 +01:00

Anton Khirnov f4281f4571 asrc_anullsrc: do not set samplerate and channel layout explicitly 
They are auto-negotiated.
 2013-03-16 05:36:35 +01:00
Anton Khirnov e4a7b2177d vf_showinfo: remove its useless init function 
Filter private data is memset to 0 so there is no point in explicitly
initing anything to 0.
 2013-03-16 05:36:14 +01:00
Anton Khirnov 4d67ff8e8e AVOptions: fix using named constants with child contexts. 
The named constant needs to be searched for in the same object on which
the option is set, i.e. target_obj.
 2013-03-16 05:35:33 +01:00
Anton Khirnov 9676b9a2cd AVOption: remove an unused function parameter. 2013-03-16 05:35:20 +01:00

Anton Khirnov 42c7c61ab2 avfiltergraph: replace AVFilterGraph.filter_count with nb_filters 
This is more consistent with the naming in the rest of Libav.
 2013-03-16 05:33:23 +01:00
Anton Khirnov 556aab8f11 lavfi: use designated initializers in avfilter_class 2013-03-16 05:33:06 +01:00
Anton Khirnov aa3c779984 lavf: sanity check size in av_get/append_packet(). 
To avoid allocating ridiculous amounts of memory for corrupted files,
read the input in chunks limited to filesize or an arbitrary large
amount when that is not known (chosen to be 50M).
 2013-03-15 20:05:04 +01:00
Anton Khirnov 3e175a2a55 avconv: mark attachment streams as immediately finished 
There are never any packets for those streams.
Fixes an infinite loop with -attach.
 2013-03-15 08:59:27 +01:00
Anton Khirnov fce68c9355 pthread: unref the decoded but not returned frames on close. 
Fixes memleaks when frame mt is used and the decoder is not flushed at
the end.
 2013-03-11 18:30:35 +01:00

Anton Khirnov f08fefc4d0 h264: remove a useless svq3 condition 
The svq3 decoder does not call ff_h264_frame_start() anymore.
 2013-03-11 18:24:36 +01:00
Anton Khirnov 07054015cf mpegvideo: remove FMT_H264 2013-03-11 18:24:25 +01:00

Anton Khirnov 19cac8e301 mpegvideo: remove useless references to h264 and svq3 
The h264 decoder does not use mpegvideo anymore. The svq3 decoder only
uses ff_draw_horiz_band().

Anton Khirnov e7553f4c78 avconv: do not silently ignore unused codec AVOptions. 
Print an error and abort when the option is of the wrong type (decoding
for output file or vice versa), since this could never be correct for
any input or output configuration.

Print a warning and continue when the option is of the correct type,
just unused, so same commandlines can be reused for different kinds of
input or output files.

Anton Khirnov db2d65ce1e avconv: fix a typo 2013-03-08 14:14:25 +01:00
Anton Khirnov 64bfc3e205 FATE: replace -vb with -b:v 
The -{vas}<option> syntax is now obsolete and deprecated, and has never
been documented or encouraged.
 2013-03-08 14:14:17 +01:00
Anton Khirnov 6deae8e053 FATE: remove the -dct option from some decoding tests. 
It is an encoding option, it has no effect when applied to decoding.
 2013-03-08 14:14:05 +01:00
Anton Khirnov 41d2008b15 avconv: use a local variable for InputFile in open_input_file().

 2013-03-08 08:12:41 +01:00
Anton Khirnov 4c0080b7e7 wmaprodec: return an error, not 0, when the input is too small. 
Returning 0 may result in an infinite loop in valid calling programs. A
decoder should never return 0 without producing any output.

 2013-03-08 08:12:26 +01:00
Anton Khirnov cacad1c058 wmaprodec: require block_align to be set.

Anton Khirnov 3e2f200237 roqvideodec: fix a potential infinite loop in roqvideo_decode_frame(). 
When there is just 1 byte remanining in the buffer, nothing will be read
and the loop will continue forever. Check that there are at least 8
bytes, which are always read at the beginning.

Anton Khirnov 8a49d2bcbe xxan: fix invalid memory access in xan_decode_frame_type0() 
The loop a few lines below the xan_unpack() call accesses up to
dec_size * 2 bytes into y_buffer, so dec_size must be limited to
buffer_size / 2.

Anton Khirnov bde48aa92d FATE: enable multiple slices in the ffv1 vsynth test 
This allows us to test the slice threading code.

it.

Anton Khirnov 37045e4229 mpegvideo: drop vismv code 
It has been broken for over a year without anyone complaining or
noticing, thus proving that nobody ever uses it.
 2013-03-08 07:40:41 +01:00
Anton Khirnov 2eba9087f3 lavc: make up a fake frame channel layout when there is no real one. 
This should ensure that a valid channel layout is always set on a frame,
until a better solution is implemented.
 2013-03-08 07:40:06 +01:00
Anton Khirnov 192f1984b1 lavc: limit maximum number of channels to 63 
This is the most that can be represented with the current channel layout

Anton Khirnov 6e7b50b427 mpegvideo_enc: drop support for reusing the input motion vectors. 
This misfeature is most likely completely useless and conflicts with
removing the mpegvideo-specific fields from AVFrame. In the improbable
case it is actually useful, it should be reimplemented in a better way.
 2013-03-08 07:37:45 +01:00
Anton Khirnov 7e350379f8 lavfi: switch to AVFrame.

Add AVBuffer-based reference counting API to it.
 2013-03-08 07:36:15 +01:00
Anton Khirnov ad0c9f2d5d lavc: move AVFrame.hwaccel_picture_private to Picture. 
This field is private and should not be present in a public struct. It
