Michael Niedermayer	46b865ea9f	avcodec/qdrw: Fix null pointer dereference The RGB555 PACKBITSRGN case tries to read a palette, if such palette is actually stored then it accesses a null pointer. All 16bit samples i could find use DIRECTBITSRGN.

Paul B Mahol	26a7d6a301	avcodec/qdrw: check bytes per scanline for 2bpp images One byte less is read in case of small width. Closes #6194. Signed-off-by: Paul B Mahol <onemda@gmail.com>	8 years ago

Paul B Mahol	f062947261	avcodec/qdrw: do better w/h parsing for direct bit packing Apparently using 0x0001 opcode solely is not correct. Try this instead. Signed-off-by: Paul B Mahol <onemda@gmail.com>	8 years ago

Vittorio Giovara	34efb8a169	quickdraw: Support direct pixel blocks Data is stored in separated components so rework decode_rle() to support stepping and offsets.	10 years ago
Vittorio Giovara	bb2cb0a66d	quickdraw: Switch to greedy parsing Quickdraw packs data as a series of codes that the application is supposed to handle, but it does not define any order in which they might appear. Since it's unfeasible to support all opcodes defined by the spec, only handle well-known blocks containing video data and ignore any unknown or unsupported ones. Move palette loading and rle decoding to separate functions to resue them in other blocks and drop format initialization in init since it can support more formats than pal8. Validate width and height.	10 years ago

Stefano Sabatini	01042d4123	lavc: set defaults in internal codec frames This is required specifically for setting frame->format to -1, otherwise it will be set to 0 = PIX_FMT_YUV420P and code reading the format from the output decoded frame will get misled.
