2008-05-07xine_xmalloc() deprecation: replace its use with static and non-zero size.Diego 'Flameeyes' Pettenò
The xine_xmalloc() function is going to be deprecated, as its behaviour is rarely needed as such, and it's thus misused. With this, almost all uses of xine_xmalloc() with static size (for instance the value returned by sizeof()) or with a size that is guaranteed not to be zero (like strlen()+1) are replaced with calls to either calloc(1, ...) or malloc(). malloc() is used whenever the allocated memory is going to be immediately overwritten, while calloc() is used in every other case, as it sets the whole memory area to zero. --HG-- extra : transplant_source : %8F%98%EC%02%1E%83%F0s%06X%83C%205Y%80%B12%CC%E1

For contributed code, leave whatever the version we last synced for is using to make simpler future syncs.
2007-09-19Convert the "AFD changed" message into a LOG message.Darren Salt
2007-08-15Workaround for recent glibc & -D_FORTIFY_SOURCE=2 (defines open() as a macro).Darren Salt
According to bug 1773769, this breaks foo->open(). The fix (as used in Ville Skyttä's patch, which doesn't cover all cases) is to replace this with (foo->open)(). This patch was generated using sed -i -re 's/(([[:alnum:]_]+(->|\.))+open) ?\(/(\1) (/' `grep '[>.]open \?(' include -rIl` One change (in a comment) is not committed.
2007-05-17Convert comments (and the occasional string where it doesn't matter) to UTF-8.Darren Salt
2007-04-12Speed up start code scanning.Reinhard Nißl
The current code implements hardware (a shift register) in software just to find the byte pattern 00 00 01 xx, which causes remarkable CPU load on less powerful machines. The new approach uses memchr() to find the 01 in the buffer, which most often hits a start code. memchr() seems to be even faster then implementing a real pattern search (i. e. by just looking at every third byte to find 01). The new implementation causes significantly fewer CPU load on less powerful machines.
2007-04-11Special handling of sequence end code to improve still frames.Reinhard Nißl
The current code emits a frame when a non slice start code is seen. For still frames, this is typically a sequence end code. But the current code doesn't call parse_chunk() immediately because it waits for a further start code to determine the chunk of data to pass to parse_chunk(). But there isn't such a further start code for still frames after the sequence end code and thus, the still frame will not be emitted. As sequence end code is the only start code which has no data according to the MPEG specification, let's use this information to call parse_chunk() immediately.
2007-04-11Detect absence of AFD and report only changes.Reinhard Nißl
The current code cannot detect the absence of AFD once it has been seen in the stream. As AFD can appear in user data after sequence, group or picture start codes, the idea is to reset the stored AFD value when processing the sequence start code. In the case where AFD is seen in user data, it is stored internally, to have it ready when the first slice is processed. At least at that time, AFD data has been seen and can be analyzed for changes. At any change, the AFD value will then be stored into a stream property. Doing this only for changes avoids locks while writing the same value over and over to the stream's property.
2007-04-11Improve MPEG2 detection to have it ready for correct aspect ratioReinhard Nißl
determination. The current code detects MPEG2 when parsing the sequence extention which appears only in MPEG2 streams. But this is to late for correct aspect ratio determination which happens earlier and therefore assumes MPEG1. The result is a totally wrong aspect ratio. To fix this issue, the next start code (which is already available at that time) is passed to parse_chunk() too, which can then be used to detect a MPEG2 extension start code early enough before the aspect ratio is determined.
