Move some functions from dsputil. The idea is that videodsp contains functions that are useful for a large and varied set of video decoders. Currently, it contains emulated_edge_mc() and prefetch(). Signed-off-by:

The FLV muxer tries to update the header in write_trailer, which is impossible if writing to a pipe or network stream. Don't write header data if seeking to the header fails. Signed-off-by:

Fixes CVE-2012-2803. CC: libav-stable@libav.org

This makes the code simpler and avoids mixing designated and non-designated initializers in a potentially unsafe way in avconv.

The sample in https://bugzilla.libav.org/show_bug.cgi?id=393 and samples/F4V/H263_NM_f.mp4 both have codec_tag H263 for different codecs. H263 is apparently used by Flash Media Server for Sorensen Spark videos. Patch based on commit 5442083b by Carl Eugen Hoyos. Fixes bug 393.

The VC1 decoder uses edge_emu_buffer simultaneously for luma and chroma and needs more space. That was not a problem before f1d8763a since the size for edge_emu_buffer was always calculated with 2 byte per pixel since the linesize was not known. Fixes occasionally fate errors in vc1_sa10143.

It results in spurious errors when using the new preparser.

It splits the commandline into a more convenient internal representation for further parsing. This will allow e.g. - processing global options first independently of their location on the commandline, eliminating ugly hacks for processing e.g. cpuflags first - better options validation and error reporting. It is now possible for the parser to know that it's applying an input option to an output file or vice versa and act accordingly.

Anton Khirnov authored
Separate the code that searches for the option to use and the code that actually writes it. The writing code will be reused by the new options parser.

Fixes CVE-2012-2782.

Janne Grunau authored
Since we can't know which stride a custom get_buffer() implementation is going to use we have to allocate this scratch buffers after the linesize is known. It was pretty safe for 8 bit per pixel pixel formats since we always allocated memory for up to 16 bits per pixel. It broke hoever with cmdutis.c's alloc_buffer() and high pixel bit depth since it allocated larger edges than mpegvideo expected. Fixes fuzzed sample nasa-8s2.ts_s244342.

It is not posible to call get_buffer during frame-mt codec initialization. Libavformat might pass huge amounts of data as extradata after parsing broken files. The 'extradata' for the fuzzed sample sample_varPAR_s5374_r001-02.avi is 2.8M large and contains multiple slices.

It adds unnecessary complication for insignificant usability improvement. The user really should know if they'll need resampling compensation before opening the context. Note that only the documentation has changed. The current functionality will still work until the next major bump.

This makes it easier for receivers to decide what to do if data is lost. Refactor calculating the max payload size, to avoid hardcoding the header size in too many places, reducing the number of lines that have to be touched if the header is adjusted further. Signed-off-by:
