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	3a7f8d2a1f	avcodec/qdrw: consume bytes when end is reached for 8bpp case This should really be part of previous commit. 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

Carl Eugen Hoyos	b453e76842	lavc/qdrw: Also support real-world qdraw images.	10 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
Vittorio Giovara	d00f1e0fc1	quickdraw: Convert to bytestream2 Add appropriate error messages and reduce r, g, b variables scope. Drop the now redundant line checks in RLE decoding.	10 years ago

Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	13 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. In particular fix regressions occurring with the pending vsrc_buffer patch.	14 years ago

Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in.

Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
