Kostya Shishkov	31980b6abd	vmd: decode videos with no LZ buffer size provided - they might not need it The buffer is used for an additional pass of frame compression, so videos can be coded without ever using it (and some are coded so indeed, e.g. in Woodruff and the Schnibble of Azimuth game).	12 years ago

Matthew Heaney	8f75ba9926	lavf/webvttdec: save cue id and settings as side data Currently the WebVTT demuxer parses the cues but throws away the cue id (the optional first line of the cue) and cue settings (the optional rendering instructions that follow the timestamp). However, in order to write inband text tracks (to WebM files), the entire cue payload from the WebVTT source must be preserved. This commit makes no change to the data part of the output buffer packet (where the actual cue text is stored), but does add the cue id and settings as a side data items, if they're present in the cue. Existing code that cares only about the data part of the packet can continue to ignore the side data. There are two new packet data type flags, AV_PKT_DATA_WEBVTT_IDENTIFIER and AV_PKT_DATA_WEBVTT_SETTINGS.	12 years ago
Clément Bœsch	151b4947e5	lavc/avpacket: fill padding area on side data split. The padding data is assumed to be 0 in several places, notably in subtitles. This problem was not detected with fate-sub-srt test because the first element of the side data (x1) is 0 in the test, so the trailing side data present in the packet wasn't read by the decoder. The issue can be observed with a large enough x1. It is also noted in FF_INPUT_BUFFER_PADDING_SIZE doxy that MPEG bitstreams require that padding with 0, so it might fix other issues.	12 years ago

Kostya Shishkov	33f64fd5d5	indeo4: expand allowed quantiser range Indeo 4 has quantiser range 0-31 instead of 0-23 for Indeo 5, and clipping quantiser leads to incorrect quantisation and DC prediction on low-quality videos. This fixes bug 259.	12 years ago
