* lavc: add new API for iterating codecs and codec parsersJosh de Kock2018-02-06

* id3v2: fix unsynchronizationwm42018-02-04
| | | | | | | | | | | | | | | The ID3v2 "unsynchronization scheme" requires replacing any 0xFF 0x00 sequences with 0xFF. This has to be done on every byte of the source data, while the current code skipped a byte after a replacement. This meant 0xFF 0x00 0xFF 00 was translated to 0xFF 0xFF 0x00 instead of 0xFF 0xFF. It feels a bit messy to do this correctly with the avio use. But fortunately, this translation can be done in-place, so we can just do it in memory. Inspired by what taglib does. Also see 9ae80e6a9cefcab61e867256ba19ef78a4bfe0cb. (The sample file for that commit is gone, so it could not be retested.)
* rtsp: rename certain options after a deprecation periodwm42018-02-04
| | | | | | The "timeout" option name inherently clashes with the meaning of the HTTP libavformat protocol option with the same name. Rename it after a deprecation period to make it compatible with the HTTP one.

* avcodec: do not use init_static_data on some codecsMuhammad Faiz2018-02-04
| | | | | | | | | | | | | | They don't modify AVCodec, no needs to call it at register. They will be wasteful if these codecs are unused. Instead, call static data initialization at codecs' init.

* librsvgdec: Fix frame clearing codeCalvin Walton2018-02-02
| | | | | | | | | | | | The existing code attempts to clear the frame by painting in OVER mode with transparent black - which is a no-op. As a result if you have many input frames (e.g. you're using a sequence of svg files), you'll start to see new frames drawn over old frames as memory gets re-used. Switch the code to paint using the CLEAR compositing operator, which fills every channel with 0 values (setting a source colour is not required).

* configure: Remove carriage return ('\r') in Windows CC_IDENTXiaohan Wang2018-02-02
| | | | | | | | | | | | | | | | | | | | | | Currently the Windows CC_IDENT is ended with '\r\n'. "head -n1" will not remove the '\r' and this is causing building error in Chromium. This CL adds "tr -d '\r'" to remove '\r' in the CC_IDENT string. Since in most cases '\r' only appears at the end of a string/line, this should work in most cases. See example: printf "hello\r\nworld\r\n" | head -n1 | hd 00000000 68 65 6c 6c 6f 0d 0a |hello..| printf "hello\r\nworld\r\n" | head -n1 | tr -d '\r' | hd 00000000 68 65 6c 6c 6f 0a |hello.| Also note a similar previous change at: https://lists.ffmpeg.org/pipermail/ffmpeg-cvslog/2013-October/069950.html Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
