Anton Khirnov 0a3ad7ff80 flvenc: use AVFormatContext, not AVCodecContext for logging. 
Encoder tag being used for muxer messages is confusing.
 2012-05-07 21:28:40 +02:00
Anton Khirnov 8134fafe9b lavfi: uninline avfilter_copy_buffer_ref_props(). 
A nontrivial public function such as this should most certainly NOT be
inline.
 2012-05-07 14:23:36 +02:00
Anton Khirnov 1432c1c429 lavf: add missing '*' in a doxy. 2012-05-07 14:22:42 +02:00
Anton Khirnov 0bbd874743 lavfi: support audio in avfilter_copy_frame_props(). 2012-05-07 07:10:48 +02:00
Anton Khirnov 828bd088f3 lavc: add sample rate and channel layout to AVFrame. 
Rationale is the same as for video width/height etc.
 2012-05-07 07:08:03 +02:00
Anton Khirnov d4ac703c7f lavfi/formats: use sizeof(var) instead of sizeof(type). 2012-05-06 16:26:41 +02:00
Anton Khirnov 25b3babe11 lavfi: always enable the scale filter and depend on sws. 
The scale filter is used for internal colorspace conversions, so it must
always be present.
 2012-05-06 16:22:29 +02:00
Anton Khirnov fd18ee0ff6 vf_split: support user-specifiable number of outputs. 2012-05-06 16:21:00 +02:00
Anton Khirnov dce415e7f1 avconv: remove stray useless comment. 2012-05-06 16:20:26 +02:00
Anton Khirnov 8c4022aceb avconv: fix a segfault on -c copy with -filter_complex. 2012-04-24 06:30:02 +02:00
Anton Khirnov 2994913d70 avconv: fix a segfault when default encoder for a format doesn't exist. 
Fail earlier and with a more descriptive error message.
 2012-04-21 06:48:28 +02:00
Anton Khirnov aff01de641 graphparser: set next to NULL on an entry extracted from inputs list 
Prevents it from referring to the rest of the list.
 2012-04-16 09:28:34 +02:00
Anton Khirnov 7ce118bae5 doc/filters: update documentation. 2012-04-15 20:37:47 +02:00
Anton Khirnov 9e8aae443b avconv: flush decoders immediately after an EOF. 
Prevents extensive buffering when overlaying a single picture.
 2012-04-15 20:37:47 +02:00
Anton Khirnov 89605e4aa0 avconv: send EOF to vsrc_buffer. 2012-04-15 20:37:47 +02:00
Anton Khirnov 3e901cbc75 avconv: reindent. 2012-04-15 20:37:42 +02:00
Anton Khirnov 3b266da3d3 avconv: add support for complex filtergraphs. 2012-04-15 20:32:09 +02:00
Anton Khirnov 560f7774a4 avconv: make filtergraphs global. 
This is the first step towards supporting complex filtergraphs with more
than one input and/or output.
 2012-04-15 20:27:32 +02:00
Anton Khirnov 836ce90566 avconv: move filtered_frame from InputStream to OutputStream. 
It more properly belongs to output, not input.
 2012-04-15 20:24:07 +02:00
Anton Khirnov 6c9eac1998 avconv: don't set output width/height directly from input value. 
Always take it from lavfi. This way we don't need a clearly defined
corresponding input stream.
 2012-04-15 20:23:09 +02:00
Anton Khirnov e77c86629f avconv: move resample_{width,height,pix_fmt} to InputStream. 
This is a more proper place for them, since they store parameters of the
input, not output, stream.
 2012-04-15 20:23:09 +02:00
Anton Khirnov 9dced85426 avconv: remove a useless variable from OutputStream. 2012-04-15 20:22:36 +02:00
Anton Khirnov b7327887ea avconv: get output pixel format from lavfi. 
This way we don't require a clearly defined corresponding input stream.

The result for the xwd test changes because rgb24 is now chosen instead
of bgra.
 2012-04-15 20:22:36 +02:00
Anton Khirnov 7af99a01c4 graphparser: fix the order in which unlabeled input links are returned. 2012-04-15 20:20:03 +02:00
Anton Khirnov 2e21526790 avconv: change {input,output}_{streams,files} into arrays of pointers. 
Right now, they are arrays of structs, reallocated when new
streams/files are added. This makes storing pointers to those structs
harder than necessary.
 2012-04-15 20:20:03 +02:00
Anton Khirnov ea9367e921 avconv: don't pass input/output streams to some functions. 
They are globals, no point in pretending they are not.
 2012-04-15 20:20:03 +02:00
Anton Khirnov 7bf9e3391f vsrc_buffer: fix check from 7ae7c41. 
The user submitted variable in this function is frame, not buf.
 2012-04-14 18:58:20 +02:00
Anton Khirnov 12e7e1d03e graphparser: allow specifying sws flags in the graph description. 2012-04-14 09:25:46 +02:00
Anton Khirnov 4e781c25b7 graphparser: fix the order of connecting unlabeled links. 
Right now, e.g. scale,[in]overlay would connect scale to the first
overlay input and [in] to the second, which goes against the
documentation and is unintuitive.

The bug happens because of the ordering mess in curr_inputs variable:
1) the unlabeled links from the previous filter are added to it in
correct order
2) input labels are parsed and inserted to the beginning one by one
(i.e. in reverse order)
3) curr_inputs is matched against filter inputs in reverse order

Fix the problem by always using proper ordering without trying to be
clever.
 2012-04-14 09:25:46 +02:00
Anton Khirnov d7bcc71dad graphparser: add avfilter_graph_parse2(). 
Unlike avfilter_graph_parse(), it returns unlinked inputs and outputs
to the caller, which allows parsing of graphs where inputs/outputs are
not known in advance.
 2012-04-14 09:25:46 +02:00
Anton Khirnov 7ae7c41413 vsrc_buffer: allow using a NULL buffer to signal EOF. 2012-04-14 09:25:46 +02:00
Anton Khirnov e36b25d1df vf_overlay: implement poll_frame() 
Signal that it can output a frame when there are frames on the main
input and EOF on the overlay input, but a frame is buffered -- e.g.
single picture overlay.
 2012-04-09 21:30:21 +02:00
Anton Khirnov 90f65dc6cf vf_scale: support named constants for sws flags. 2012-04-09 21:29:05 +02:00
Anton Khirnov 7c59b5c2a5 lavc doxy: add all installed headers to doxy groups. 2012-04-09 21:25:17 +02:00
Anton Khirnov ec57b7de74 lavc doxy: add avfft to the main lavc group. 2012-04-09 21:24:46 +02:00
Anton Khirnov 8a74029ea2 lavc doxy: add remaining avcodec.h functions to a misc doxygen group. 2012-04-09 21:18:47 +02:00
Anton Khirnov 6aadfbda09 lavc doxy: add AVPicture functions to a doxy group. 2012-04-09 21:18:28 +02:00
Anton Khirnov 56512ce104 lavc doxy: add resampling functions to a doxy group. 2012-04-09 21:18:19 +02:00
Anton Khirnov 40ca0e6a75 lavc doxy: replace \ with / 
It's the more proper symbol to use and it prevents doxygen from thinking
it's a command.
 2012-04-09 21:16:37 +02:00
Anton Khirnov f038515f0a lavc doxy: add encoding functions to a doxy group. 2012-04-09 21:16:24 +02:00
Anton Khirnov c8ef8464c2 lavc doxy: add decoding functions to a doxy group. 2012-04-09 21:14:05 +02:00
Anton Khirnov 199ada4944 lavc doxy: fix formatting of AV_PKT_DATA_{PARAM_CHANGE,H263_MB_INFO} 2012-04-09 21:13:49 +02:00
Anton Khirnov 30f3f62563 lavc doxy: add AVPacket-related stuff to a separate doxy group. 
Also move AV_PKT_DATA_PARAM_CHANGE/AV_PKT_DATA_H263_MB_INFO to the
proper place.
 2012-04-09 21:13:17 +02:00
Anton Khirnov 294b3a5074 lavc doxy: add core functions/definitions to a doxy group. 2012-04-09 21:12:53 +02:00
Anton Khirnov b6c4518a87 avconv: remove OutputStream.picref. 
It's only used inside transcode_video() and there's no point in
preserving it between subsequent calls. So use a local variable instead.
 2012-04-09 05:13:00 +02:00
Anton Khirnov 695ec04e6a avconv: only set SAR once on the decoded frame. 
No point in repeating the assignment for each output stream.
 2012-04-09 05:10:38 +02:00
Anton Khirnov d4936548f4 avconv: remove an unused function parameter. 2012-04-06 20:21:07 +02:00
Anton Khirnov 4648fe6324 avconv: remove now pointless variables. 2012-04-06 20:21:07 +02:00
Anton Khirnov e06d2dfcde avconv: drop support for building without libavfilter. 
Since the mandatory memcpy in vsrc_buffer has been eliminated, there
shouldn't be any significant reason to build without lavfi anymore.

This will make upcoming support for complex filtergraphs easier to do.
 2012-04-06 20:21:07 +02:00
Anton Khirnov a03f8ea0a8 vsrc_buffer: when no frame is available, return an error instead of segfaulting. 2012-04-05 09:30:09 +02:00
Anton Khirnov cfec77aaf8 configure: add dl to frei0r extralibs. 2012-04-05 09:20:03 +02:00
Anton Khirnov 95587d29d7 vsrc_buffer: allow buffering arbitrary number of frames. 2012-04-01 09:04:19 +02:00
Anton Khirnov 416fd90ead vf_scale: avoid a pointless memcpy in no-op conversion. 
I.e. just pass the buffer along when src parameters == dst parameters.
 2012-04-01 09:04:14 +02:00
Anton Khirnov 63736fe48c avfiltergraph: try to reduce format conversions in filters. 
Current code, with a filterchain such as
(input - yuv411) -> (scale - any) -> (sink - any)
will result in yuv420 being chosen for the second link, which is clearly
not right.

This commit attempts to improve in the following way:
repeat until convergence:
  loop over all filters
    find input link with exactly one format
    force this format on all output links of the same type (if possible)
 2012-04-01 09:04:09 +02:00
Anton Khirnov 996f9f0c32 avfiltergraph: add an AVClass to AVFilterGraph on next major bump. 
It will be used for logging, possibly also AVOptions.
 2012-04-01 09:03:35 +02:00
Anton Khirnov ddb4431208 id3v2: fix skipping extended header in id3v2.4 
In v2.4, the length includes the length field itself.
 2012-04-01 09:02:24 +02:00
Anton Khirnov a839dbb94e dvenc: print allowed profiles if the video doesn't conform to any of them. 2012-03-28 09:29:04 +02:00
Anton Khirnov 3c6607eb6f avcodec_encode_{audio,video}: only reallocate output packet when it has non-zero size. 
Otherwise realloc would free it, which would result in double free
later.
 2012-03-28 09:28:47 +02:00
Anton Khirnov e2e165c00f FATE: add a test for vp8 with changing frame size. 2012-03-28 09:28:29 +02:00
Anton Khirnov 967923abd1 lavf doxy: expand AVStream.codec doxy. 2012-03-26 10:59:43 +02:00
Anton Khirnov e44ada129c lavf doxy: improve AVStream.time_base doxy. 
Remove confusing sentence that implied the user should set the timebase.
Elaborate on how the timebase is set for muxing.
 2012-03-26 10:59:43 +02:00
Anton Khirnov f58b8cc3e3 lavf doxy: add some basic documentation about reading from the demuxer. 2012-03-26 10:59:43 +02:00
Anton Khirnov 10fa4ff7bc lavf doxy: document passing options to demuxers. 2012-03-26 10:59:43 +02:00
Anton Khirnov dca9c81d82 lavf doxy: clarify that an AVPacket contains encoded data. 2012-03-26 10:59:42 +02:00
Anton Khirnov 9c47f2b294 APIchanges: mark the place where 0.7 was cut. 2012-03-26 10:08:58 +02:00
Anton Khirnov 75bdd55e77 APIchanges: mark the place where 0.8 was cut. 2012-03-26 10:08:57 +02:00
Anton Khirnov 5d20e7b7ea APIchanges: fill in missing dates and hashes. 2012-03-26 10:08:56 +02:00
Anton Khirnov 677df4d2ef pngenc: better upper bound for encoded frame size. 
Fixes encoding very large pictures.

Thanks to Костя for providing the formula.
 2012-03-22 19:50:35 +01:00
Anton Khirnov a6733202cc lavf: make av_interleave_packet_per_dts() private. 
There is no reason for it to be public, it's only meant to be used
internally.
 2012-03-20 20:12:16 +01:00
Anton Khirnov 3c90cc2ef2 lavf: deprecate av_read_packet(). 
The caller can achieve the same effect (i.e. getting raw unparsed/mangled
packets) with av_read_frame() and AVFMT_FLAG_NOPARSE |
AVFMT_FLAG_NOFILLIN
 2012-03-20 20:12:16 +01:00
Anton Khirnov 0d0b81f941 Generate manpages for AV{Format,Codec}Context AVOptions. 2012-03-20 07:10:06 +01:00
Anton Khirnov 4fea8959d8 doc/avconv: remove entries for AVOptions. 
Documentation for those will be generated automatically.
 2012-03-20 07:09:54 +01:00
Anton Khirnov 5626697104 Move AVFormatContext/AVCodecContext option tables to separate files. 
This will allow us to automatically generate manpages for them.
 2012-03-20 07:09:18 +01:00
Anton Khirnov 40b41be3fa lavf: use AVStream.discard to disable queueing attached pictures. 2012-03-20 06:53:44 +01:00
Anton Khirnov 01fcc42b90 lavf: requeue attached pictures after seeking. 
This allows the caller to get them without special code even after
seeking before receiving any data.
 2012-03-20 06:52:33 +01:00
Anton Khirnov 713f3062a7 id3v2: set the keyframe flag on attached pictures. 2012-03-20 06:52:07 +01:00
Anton Khirnov 8bc5d90a7e lavf: remove some disabled code. 2012-03-17 22:37:55 +01:00
Anton Khirnov f35f8eeb0d lavf: only set average frame rate for video. 2012-03-17 22:36:56 +01:00
Anton Khirnov 9ade26ee91 lavf: remove a pointless check. 
Timebase is already checked in avpriv_set_pts_info().
 2012-03-17 22:36:48 +01:00
Anton Khirnov cd9a3c3512 lavf: don't select an attached picture as default stream for seeking. 2012-03-15 14:01:05 +01:00
Anton Khirnov 251422982b avconv: remove pointless checks. 
OutputStream.picref is guaranteed to be non-NULL if
get_filtered_video_frame() succeeds.
 2012-03-15 09:01:18 +01:00
Anton Khirnov ce326c1130 avconv: check for get_filtered_frame() failure. 2012-03-15 09:00:55 +01:00
Anton Khirnov 2636e691ce avconv: remove a pointless check. 
output_video_filter is always guaranteed to be set and is in fact
dereferenced right above the check.
 2012-03-15 09:00:49 +01:00
Anton Khirnov 972880f597 doc/general: update supported devices table. 
Add libcdio and fbdev, remove v4l1.
 2012-03-13 22:01:51 +01:00
Anton Khirnov 29e4046e83 doc/general: add missing @tab to codecs table. 2012-03-13 22:01:51 +01:00
Anton Khirnov 64334ddbbc avconv: reindent 
CC: libav-stable@libav.org
 2012-03-13 12:21:44 +01:00
Anton Khirnov 6e8be949f1 avconv: link '-passlogfile' option to libx264 'stats' AVOption. 
Fixes bug 204.

CC: libav-stable@libav.org
 2012-03-13 12:21:14 +01:00
Anton Khirnov d533e395e1 libx264: add 'stats' private option for setting 2pass stats filename. 
x264 always opens the file itself with fopen, so we cannot use the
standard lavc stats mechanism.

CC: libav-stable@libav.org
 2012-03-13 12:20:50 +01:00
Anton Khirnov 9d5c131ece libx264: fix help text for slice-max-size option. 
CC: libav-stable@libav.org
 2012-03-13 12:20:34 +01:00
Anton Khirnov 018f39ef49 FATE: add CPUFLAGS variable, mapping to -cpuflags avconv option. 2012-03-06 15:03:36 +01:00
Anton Khirnov 4138cd2907 avconv: add -cpuflags option for setting supported cpuflags. 
Useful for testing.
 2012-03-06 15:03:22 +01:00
Anton Khirnov 4d851f8dcf cpu: add av_set_cpu_flags_mask(). 2012-03-06 15:02:28 +01:00
Anton Khirnov 39da3b223f avconv: fix counting encoded video size. 
avcodec_encode_video2() return value is 0 on success, encoded frame size
is stored in the packet.
 2012-03-06 10:06:21 +01:00
Anton Khirnov 27c7ca9c12 lavf: deobfuscate read_frame_internal(). 
Split off packet parsing into a separate function. Parse full packets at
once and store them in a queue, eliminating the need for tracking
parsing state in AVStream.

The horrible unreadable loop in read_frame_internal() now isn't weirdly
ordered and doesn't contain evil gotos, so it should be much easier to
understand.

compute_pkt_fields() now invents slightly different timestamps for two
raw vc1 tests, due to has_b_frames being set a bit later. They shouldn't
be more wrong (or right) than previous ones.
 2012-03-05 18:47:05 +01:00
Anton Khirnov dcee811505 lavf: make read_from_packet_buffer() more flexible. 
Make packet buffer a parameter, don't hardcode it to be
AVFormatContext.packet_buffer.

Also move the function higher in the file, since it will be called from
read_frame_internal().
 2012-03-05 18:44:45 +01:00
Anton Khirnov 52b0943f10 lavf: factorize freeing a packet buffer. 2012-03-05 18:44:30 +01:00
Anton Khirnov 3faa141d15 cmdutils: use new avcodec_is_decoder/encoder() functions. 
Fixes listing encoders.
 2012-03-04 21:09:35 +01:00
Anton Khirnov 44fe77b350 lavc: make codec_is_decoder/encoder() public. 2012-03-04 21:08:52 +01:00
Anton Khirnov 02beb9826b lavc: deprecate AVCodecContext.sub_id. 
In most places where it's used, it's as a pointless write-only field.

Only rv10 decoder actually reads from it, but it stores some internal
version info in it. There is no reason for it to be in a public field.
 2012-03-04 21:02:45 +01:00
Anton Khirnov 87392b1fd5 libcdio: add a forgotten AVClass to the private context. 2012-03-04 21:01:41 +01:00
