2021-01-29Relax constraints on Y4M header parsingElliott Karpilovsky1-24/+54
Previous parser assumed that the header would not exceed 80 characters. However, with latest FFMPEG changes, the header of Y4M files can exceed this limit. New parser can parse an arbitrarily long header, as long each tag is 255 or less characters. BUG=aomedia:2876 Change-Id: I9e6e42c50f4e49251dd697eef8036485ad5a1228
2021-01-28Relax constraints on Y4M header parsingElliott Karpilovsky1-31/+45
Previous parser assumed that the header would not exceed 80 characters. However, with latest FFMPEG changes, the header of Y4M files can exceed this limit. New parser can parse up to ~200 characters. Arbitrary parsing in future commit. BUG=aomedia:2876 Change-Id: I2ab8a7930cb5b76004e6731321d0ea20ddf333c1
2021-01-14Relax constraints on Y4M header parsingElliott Karpilovsky1-188/+206
Some refactoring and cleanup -- do not count the first 9 bytes against the header limit. Add a unit test. BUG=aomedia:2876 Change-Id: Id897d565e2917b48460cc77cd082cec4c98b42cb
2018-04-09vpx_image: remove unused image formatsJames Zern1-24/+0
libvpx only emits: VPX_IMG_FMT_{I420,I422,I440,I444,I42016,I42216,I44016,I44416} and additionally supports YV12 as input. interleaved yuv, rgb and alpha formats are unused. Change-Id: Ie2ab1099e950c6e696f475d46882f5c47a174042
2018-04-02remove support for yuv 411Johann1-0/+2
Previously we attempted to convert 411 input. Remove support because malformed 411 input can cause the conversion to crash. BUG=webm:1386 Change-Id: I3d41465a94867ee7f8eaa43fb76beb41f8fa644b

2014-07-05Adds support for reading and writing 10/12-bit y4mDeb Mukherjee1-10/+115
The y4m extension used is the same as the one used in ffmpeg/x264. The patch is adapted from the highbitdepth branch. Also adds unit tests for y4m header parsing and md5 check of the raw frame data, as well as y4m writing.

2013-05-06Y4M input support for 4:2:2, 4:4:4, 4:4:4:4John Koleszar1-35/+76
Adds a new experiment CONFIG_NON420 that allows other chroma subsamplings to be passed to the codec. This commit allows the data to be passed from a y4m input file through vpxenc to the codec, where they're currently rejected. Later commits will finish support for this inside the codec.

2010-10-27Eliminate more warnings.Timothy B. Terriberry1-1/+1
This eliminates a large set of warnings exposed by the Mozilla build system (Use of C++ comments in ISO C90 source, commas at the end of enum lists, a couple incomplete initializers, and signed/unsigned comparisons). It also eliminates many (but not all) of the warnings expose by newer GCC versions and _FORTIFY_SOURCE (e.g., calling fread and fwrite without checking the return values). There are a few spurious warnings left on my system: ../vp8/encoder/encodemb.c:274:9: warning: 'sz' may be used uninitialized in this function gcc seems to be unable to figure out that the value shortcut doesn't change between the two if blocks that test it here. ../vp8/encoder/onyx_if.c:5314:5: warning: comparison of unsigned expression >= 0 is always true ../vp8/encoder/onyx_if.c:5319:5: warning: comparison of unsigned expression >= 0 is always true This is true, so far as it goes, but it's comparing against an enum, and the C standard does not mandate that enums be unsigned, so the checks can't be removed.

2010-06-02Add support for reading YUV4MPEG2 files to ivfenc.Timothy B. Terriberry1-0/+880
A large collection of example files may be found at http://media.xiph.org/video/derf/ This also fixes a bug in ivfenc for uncompressed IVF input, which previously appeared not to skip past the file header the second time it opened the file. I don't actually have an IVF file with which to test this fix, however. Change-Id: Id69a1e11a3fa16c4a4fa8944e880bcea090cd52b
