* mp3: Tweak the probe scoresLuca Barbato2014-12-07
| | | | | | | | Having more than 10 consecutive frames decoded as mp3 should be considered a clear signal that the sample is mp3 and not mpegps. Reported-By: Florian Iragne <florian@iragne.fr> CC: libav-stable@libav.org

* exr: Add a gamma flag to exr loader to avoid bandingGonzalo Garramuno2014-12-03
| | | | | | | | This is needed to avoid banding artifacts when gammaing the picture. Currently, if done with a video filter, the process is done on uints instead of full float. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* options_table: fix colorspace minimum option valueJon Morley2014-12-02
| | | | | The min value for colorspace should be zero and not one since the first valid index into the frame colorspace array is AVCOL_SPC_RGB which is 0.
* mov: allocate the tag value dynamicallyThilo Borgmann2014-12-02
| | | | | | | | This allows to load metadata entries longer than 1024 bytes. Displaying them is still limited to 1024 characters, but applications can load them fully now. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

| | | | | With --disable-optimizations, the DCE of some compilers does not remove such unused code, causing linking failure.
* aac: Simplify decode_mid_side_stereoLuca Barbato2014-12-02

* Treat all '*.pnm' files as non-text fileReinhard Tartler2014-11-28
| | | | | | | | This convinces the pre-receive hook to not consider all *.pnm files as text files to reduce the patch sizes and avoids triggering whitespace checks, Contains a correction by Janne Grunau <janne-libav@jannau.net>

* dashenc: Avoid a VLA-like constructMartin Storsjö2014-11-28

* dashenc: Add options to make segment names configurableBryan Huh2014-11-28
| | | | | | | This allows one to specify templated segment names for init-segments, media-segments, and for the base-url in the case of single-file. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtmpproto: Only prepend @setDataFrame for onMetaData and |RtmpSampleAccessMartin Storsjö2014-11-28
| | | | | | | | | | | | | | | | | | | | | | Currently, when streaming to an RTMP server, any time a packet of type RTMP_PT_NOTIFY is encountered, the packet is prepended with @setDataFrame before it gets sent to the server. This is incorrect; only packets for onMetaData and |RtmpSampleAccess should invoke @setDataFrame on the RTMP server. Specifically, the current bug manifests itself when trying to stream onTextData or onCuePoint invocations. This fix addresses that problem and ensures that the @setDataFrame is only prepended for onMetaData and |RtmpSampleAccess. Since data is fed to the rtmp_write function in smaller pieces (depending on the calling IO buffer size), we can't generally assume that the whole packet (or even the whole command string) is available at once, therefore we can only check the command string once the full packet has been transferred to us for sending. Based on a patch by Jeffrey Wescott. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtmppkt: Make pkt->data reallocableMartin Storsjö2014-11-28
| | | | | | | | We try to avoid mixing av_malloc with av_realloc, since av_malloc may be implemented with functions that can't (formally) be mixed with the functions used in av_realloc. Signed-off-by: Martin Storsjö <martin@martin.st>

* lavu: fix memory leaks by using a mutex instead of atomicswm42014-11-27
| | | | | | | | | | | | | | | | | | | | | The buffer pool has to atomically add and remove entries from the linked list of available buffers. This was done by removing the entire list with a CAS operation, working on it, and then setting it back again (using a retry-loop in case another thread was doing the same thing). This could effectively cause memory leaks: while a thread was working on the buffer list, other threads would allocate new buffers, increasing the pool's total size. There was no real leak, but since these extra buffers were not needed, but not free'd either (except when the buffer pool was destroyed), this had the same effects as a real leak. For some reason, growth was exponential, and could easily kill the process due to OOM in real-world uses. Fix this by using a mutex to protect the list operations. The fancy way atomics remove the whole list to work on it is not needed anymore, which also avoids the situation which was causing the leak. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavu: add wrappers for the pthreads mutex APIAnton Khirnov2014-11-27
| | | | | | | | | | Also add no-op fallbacks when threading is disabled. This helps keeping the code clean if Libav is compiled for targets without threading. Since we assume that no threads of any kind are used in such configurations, doing nothing is ok by definition. Based on a patch by wm4 <nfxjfg@googlemail.com>.
* Revert "lavf: Don't try to update files atomically with renames on windows"Martin Storsjö2014-11-27
| | | | | | | | | This reverts commit b9d08c77a44390b0848c06f20bc0e9e951ba6a3c. After taking MoveFileEx into use, we can replace files with renames on windows as well. Signed-off-by: Martin Storsjö <martin@martin.st>
* lavf: Use MoveFileEx instead of rename/_wrename on windowsMartin Storsjö2014-11-27
| | | | | | | | | This allows getting the normal unix semantics, where a rename allows replacing an existing file. Based on a suggestion by Reimar Döffinger. Signed-off-by: Martin Storsjö <martin@martin.st>
* Share the utf8 to wchar conversion routine between lavf and lavuMartin Storsjö2014-11-27
| | | | | | | | This doesn't add any dependency on library internals, since this only is a static inline function that gets built into each of the calling functions - this is only to reduce the code duplication. Signed-off-by: Martin Storsjö <martin@martin.st>
* movenc: Expose the fragment index as an avoptionMartin Storsjö2014-11-26
| | | | | | | | This allows setting the right fragment number if doing random-access writing of fragments, and also allows reading the current sequence number. Signed-off-by: Martin Storsjö <martin@martin.st>
* movenc: Add a flag for indicating a discontinuous fragmentMartin Storsjö2014-11-26
| | | | | | | | | | | | | | | | | | | | | | | This allows creating a later mp4 fragment without sequentially writing the earlier ones before (when called from a segmenter). Normally when writing a fragmented mp4 file sequentially, the first timestamps of a fragment are adjusted to match the end of the previous fragment, to make sure the timestamp is the same, even if it is calculated as the sum of previous fragment durations. (And for the first packet in a file, the offset of the first packet is written using an edit list.) When writing an individual mp4 fragment discontinuously like this (with potentially writing the earlier fragments separately later), there's a risk of getting a gap in the timeline if the duration field of the last packet in the previous fragment doesn't match up with the start time of the next fragment. Using this requires setting -avoid_negative_ts make_non_negative (or -avoid_negative_ts 0). Signed-off-by: Martin Storsjö <martin@martin.st>
