* asfdec: make sure packet_size is non-zero before seekingAndreas Cadhalpun2016-02-07
| | | | | | | This fixes infinite loops due to seeking back. Signed-off-by: Alexandra Hájková <alexandra@khirnov.net> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* asfdec: check for too small size in asf_read_unknownAndreas Cadhalpun2016-02-07
| | | | | | | This fixes infinite loops due to seeking back. Signed-off-by: Alexandra Hájková <alexandra@khirnov.net> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* asfdec: check avio_skip in asf_read_simple_indexAndreas Cadhalpun2016-02-07
| | | | | | | | The loop can be very long, even though the file is very short. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> Signed-off-by: Alexandra Hájková <alexandra@khirnov.net> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* asfdec: break if EOF is reached after asf_read_packet_headerAndreas Cadhalpun2016-02-07
| | | | | | | | | | | asf_read_payload can unset eof_reached, so check it also before calling that function. This fixes infinite loops.

* libx264: Make sure to preserve default option valuesVittorio Giovara2016-02-01
| | | | | | | | The private options chromaoffset, sc_threshold, and noise_reduction were set to 0 rather than -1, and were always initializing values in libx264 rather than letting the library use its default. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* hls: eliminate ffurl_* usageAnton Khirnov2016-01-24
| | | | | Now all IO should go through the IO callbacks and be interceptable by the caller.
* lavf: allow custom IO for all filesAnton Khirnov2016-01-24
| | | | | | | | | | | | | | Some (de)muxers open additional files beyond the main IO context. Currently, they call avio_open() directly, which prevents the caller from using custom IO for such streams. This commit adds callbacks to AVFormatContext that default to avio_open2()/avio_close(), but can be overridden by the caller. All muxers and demuxers using AVIO are switched to using those callbacks instead of calling avio_open()/avio_close() directly. (de)muxers that use the URLProtocol layer directly instead of AVIO remain unconverted for now. This should be fixed in later commits.
* qsvenc: fix a typoAnton Khirnov2016-01-23
| | | | Introduced in 0e6c8532215790bbe560a9eea4f3cc82bb55cf92.
* x86inc: Add debug symbols indicating sizes of compiled functionsGeza Lore2016-01-23
| | | | | | | | | | | Some debuggers/profilers use this metadata to determine which function a given instruction is in; without it they get can confused by local labels (if you haven't stripped those). On the other hand, some tools are still confused even with this metadata. e.g. this fixes `gdb`, but not `perf`. Currently only implemented for ELF. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* x86inc: Avoid creating unnecessary local labelsHenrik Gramner2016-01-23
| | | | | | | | | | | | The REP_RET workaround is only needed on old AMD cpus, and the labels clutter up the symbol table and confuse debugging/profiling tools, so use EQU to create SHN_ABS symbols instead of creating local labels. Furthermore, skip the workaround completely in functions that definitely won't run on such cpus. Note that EQU is just creating a local label when using nasm instead of yasm. This is probably a bug, but at least it doesn't break anything. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* x86inc: Simplify AUTO_REP_RETHenrik Gramner2016-01-23
| | | | | | | | cpuflags is never undefined any more, it's set to 0 instead. Also fix an incorrect comment. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* x86inc: Preserve arguments when allocating stack spaceHenrik Gramner2016-01-23
| | | | | | | | When allocating stack space with a larger alignment than the known stack alignment a temporary register is used for storing the stack pointer. Ensure that this isn't one of the registers used for passing arguments. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* x86inc: Improve FMA instruction handlingHenrik Gramner2016-01-23
| | | | | | | | | | | | | | * Correctly handle FMA instructions with memory operands. * Print a warning if FMA instructions are used without the correct cpuflag. * Simplify the instantiation code. * Clarify documentation. Only the last operand in FMA3 instructions can be a memory operand. When converting FMA4 instructions to FMA3 instructions we can utilize the fact that multiply is a commutative operation and reorder operands if necessary to ensure that a memory operand is used only as the last operand.

| | | | | | | | | | This option is only used by mpegvideoenc and openh264. It is a very codec-specific option, so deprecate the global variant. The openh264 option is dropped altogether since it is just a fallback for -max_nal_size anyway. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
