* avformat/libopenmpt: Probe file format from file data if possibleJörn Heusipp2018-03-201-0/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building with libopenmpt 0.3, use the libopenmpt file header probing functions for probing. libopenmpt probing functions are allocation-free and designed to be as fast as possible. For libopenmpt 0.2, or when libopenmpt 0.3 file header probing cannot probe successfully due to too small probe buffer, test the filename against the file extensions supported by the libopenmpt library that is actually linked, instead of relying on a hard-coded file extension list. File extension testing is also allocation-free and designed to be fast in libopenmpt. Avoiding a hard-coded file extension list is useful because later libopenmpt versions will likely add support for more module file formats. libopenmpt file header probing is tested regularly against the FATE suite and other diverse file collections by libopenmpt upstream in order to avoid false positives. FATE passes with './configure --enable-libopenmpt' as well as with './configure --enable-libopenmpt --enable-libmodplug'. libopenmpt probing adds about 5%..10% cpu time (depending on precise usage pattern and host CPU and compiler version used for libopenmpt) compared to all current internal FFmpeg probing functions combined in tools/probetest for all of its module formats combined (currently 41 modules formats in libopenmpt 0.3.4 and 234 file formats in FFmpeg).

* ffmpeg.c - drain all decoded frames during stream_loop flushGyan Doshi2018-03-201-6/+11
| | | | | | | | | | | | | | When a decoded stream is being looped, after each post-EOF rewind, decoders are flushed in seek_to_start(). This only drains 1 frame, and thus the output has a few frames missing at the tail of each iteration except the last. With this patch, process_input is looped till process_input_packet reaches EOF.

* cbs_h264: Fix overflow in shiftsMark Thompson2018-03-182-11/+15
| | | | | | | | | The type of the result of a shift operation is unaffected by the type of the right operand, so some existing code overflows with undefined behaviour when the element length is 32. Add a helper macro to calculate the maximum value correctly and then use it everywhere this pattern appears. Found-by: Andreas Rheinhardt <andreas.rheinhardt@googlemail.com>

* http: fix potentially dangerous whitespace skipping codewm42018-03-181-0/+2
| | | | | | | | | | | | | If the string consists entirely of whitespace, this could in theory continue to write '\0' before the start of the memory allocation. In practice, it didn't really happen: the generic HTTP header parsing code already skips leading whitespaces, so the string is either empty, or consists a non-whitespace. (The generic code and the cookie code actually have different ideas about what bytes are whitespace: the former uses av_isspace(), the latter uses WHITESPACES. Fortunately, av_isspace() is a super set of the http.c specific WHITESPACES, so there's probably no case where the above assumption could have been broken.)
* http: avoid out of bound accesses on broken Set-Cookie headerswm42018-03-181-0/+3
| | | | | | | | It's trivial to craft a HTTP response that will make the code for skipping trailing whitespace access and possibly overwrite bytes outside of the memory allocation. Why this can happen is blindingly obvious: it accesses cstr[strlen(cstr)-1] without checking whether the string is empty.
* http: do not print a warning message for expired cookieswm42018-03-181-1/+1
| | | | | | | libavformat prints a warning that the cookie couldn't be parsed (see callers of parse_cookie()). This is obviously not true - it could be parsed, but was simply ignored. Don't return an error to avoid the warning.
* lavu/frame: add QP side datawm42018-03-186-7/+86
| | | | | | | | | | | | | | | | | | | This adds a way for an API user to transfer QP data and metadata without having to keep the reference to AVFrame, and without having to explicitly care about QP APIs. It might also provide a way to finally remove the deprecated QP related fields. In the end, the QP table should be handled in a very similar way to e.g. AV_FRAME_DATA_MOTION_VECTORS. There are two side data types, because I didn't care about having to repack the QP data so the table and the metadata are in a single AVBufferRef. Otherwise it would have either required a copy on decoding (extra slowdown for something as obscure as the QP data), or would have required making intrusive changes to the codecs which support export of this data. The new side data types are added under deprecation guards, because I don't intend to change the status of the QP export as being deprecated (as it was before this patch too).
* lavu/frame: fix inconsistent qp_table_buf deprecationwm42018-03-182-3/+5
| | | | | | Everything related to the QP data is deprecated, with qp_table_buf being an inconsistent exception. Some parts were under the deprecation guards, some not. It probably didn't even compile.
