2011-07-10matroskadec: defer parsing of cues element until we seek.Aaron Colwell
This decreases startup latency. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>
2011-07-01matroskadec: matroska_read_seek after after EBML_STOP leads to failure.John Stebbins
EBML_STOP leaves matroska->current_id set. Then matroska_read_seek changes the stream position without resetting current_id. The next matroska_parse_cluster fails due to calculation of incorrect pos. So clear current_id when avio_seek happens in matroska_read_seek. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

2011-04-19avio: remove AVIO_* access symbols in favor of new AVIO_FLAG_* symbolsStefano Sabatini
Make AVIO_FLAG_ access constants work as flags, and in particular fix the behavior of functions (such as avio_check()) which expect them to be flags rather than modes. This breaks API.
2011-04-14handle malloc failures in ff_get_wav_headerMax Horn
ff_get_wav_header is reading data from a WAVE file and then uses it (without validation) to malloc a buffer. It then proceeded to read data into the buffer, without verifying that the allocation succeeded. To address this, change ff_get_wav_header to return an error if allocation failed, and adapted all calling code to handle that error. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
2011-04-07avio: AVIO_ prefixes for URL_ open flags.Anton Khirnov
2011-04-04avio: introduce an AVIOContext.seekable fieldAnton Khirnov
Use it instead of url_is_streamed and AVIOContext.is_streamed.
2011-03-25matroskadec: set default duration for simple blockJohn Stebbins
When a normal Block is parsed, duration is initialized to AV_NOPTS_VALUE. If it is not changed, then the track's default duration is used. But for SimpleBlock, duration is initialized to 0 instead of AV_NOPTS_VALUE. This is due to the difference in how EBML_NEST vs EBML_PASS are processed. Setting duration to 0 leads eventually to wrongly estimate the frame duration in util.c Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

In the name of consistency: put_byte -> avio_w8 put_<type> -> avio_w<type> put_buffer -> avio_write put_nbyte will be made private put_tag will be merged with avio_put_str Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
2011-02-21avio: avio_ prefixes for get_* functionsAnton Khirnov
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. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
2011-02-20avio: move init_put_byte() to a new private header and rename itAnton Khirnov
init_put_byte should never be used outside of lavf, since sizeof(AVIOContext) isn't part of public ABI. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

2011-02-07matroskadec: add generic element length validation.Reimar Döffinger
This validate the length of a mkv element directly after reading it. This has the advantage that it is easy to add new limits and makes it less likely to forget to add checks and also avoids issues like bits of the length value above the first 32 being ignored because the parsing functions only takes an int. Previously discussed in the "mkv 0-byte integer parsing" thread. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
2011-01-27Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice.Diego Elio Pettenò
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.
