* aac: Relax reserved_bit validationVittorio Giovara2015-03-04
| | | | | | | | | | | Although the specification mandates this bit to zero, it may happen that software tools incorrectly flip it to one, invalidating a possibly valid stream. Relax this restriction, by failing only when AV_EF_BITSTREAM is set. This behaviour is similar to aac decoders in Firefox and Quicktime. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* rtpdec_mpa_robust: Fix incrementing split_posMartin Storsjö2015-03-04
| | | | | | | | | This fixes an oversight in 96084251, in a refactoring done on top of Gilles' original patch. Pointed out by Gilles Chanteperdrix. Signed-off-by: Martin Storsjö <martin@martin.st>
* wma.h: #include "avcodec.h"Anton Khirnov2015-03-03
| | | | | | It's required for at least AVCodecContext. Fixes make checkheaders.
* asf: do not export XMP metadata by defaultVittorio Giovara2015-03-03
| | | | | | | | | | | Similarly to what has been done for MOV, display XMP metadata only when users explicitly require it. The Extensible Metadata Platform tag can contain various kind of data which are not strictly related to the video file, such as history of edits and saves from the project file.

* fate: Add AIC test with odd sizesVittorio Giovara2015-03-03

* aic: Fix decoding files with odd dimensionsVittorio Giovara2015-03-03
| | | | | | | | | Normally the aic decoder finds the proper slice combination (multiple of some number less than 32) but in case of odd width, it resorts to the default values, which were actually swapped. The number of slices is modified to account for such odd width cases. CC: libav-stable@libav.org

* Revert "mov: Change DTS-based seek into CTS-based seek."Martin Storsjö2015-03-02
| | | | | | | | | | | This reverts commit 4abfa387b8234736f6e0e541951e3d5eb60eb843. This commit broke playback of fragmented mp4 files with b-frames. While investigating this, it turned out that the general framework isn't ready for a PTS-based index yet. Revert this change until a better thought out solution is in place.

* v4l2: Use the codec descriptor facilityLuca Barbato2015-03-02
| | | | | The encoder or decoder might be disabled but the format would be supported for at least remuxing.
* prores: Extend the padding check to 16bitLuca Barbato2015-03-02
| | | | | | | | | | | Some files produced by the official encoder have up to 16bit of padding instead of the expected padding to the byte. Use a self-explanatory macro instead of a simple number. CC: libav-stable@libav.org Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* rtpenc: Don't set max_frames_per_packet based on the packet frame size or ↵Martin Storsjö2015-02-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | frame rate Instead check the timestamps while muxing, to avoid buffering a too long timestamp range into one single packet. This makes the AMR and AAC packetization slightly less efficient, since we set a possibly unnecessarily high max_frames_per_packet. (These packetizers end up doing a memmove of the TOC bytes if sending a packet before max_frames_per_packet is achieved, and we end up setting max_frames_per_packet to a value that should be high enough for most uses.) All packetizers that use max_frames_per_packet now set it either to a default value, or to a value calculated based on other parameters, so none of them rely on the previous default setting. For iLBC, copy one frame at a time, to allow checking the timestamp range for each of them - basically doing potentially multiple loops to simplify the code instead of trying to calculate the number of frames to buffer while honoring s1->max_delay. This is in preparation for reducing the coupling between libavformat and libavcodec, by not having the muxers use the encoder field frame_size (which may not be available during e.g. stream copy).

* rtpenc: Restructure if statements in packetizers to simplify adding more ↵Martin Storsjö2015-02-28
| | | | | | | | | | conditions Factorize out the s->num_frames check at the start of the if statements, simplifying adding more alternative causes for sending the buffered frames. Signed-off-by: Martin Storsjö <martin@martin.st>

* rtpenc: Always do the default initialization regardless of codecsMartin Storsjö2015-02-28
| | | | | | | | This avoids having to jump to the defaultcase in the switch. Manually override the stream time base back to 90 kHz for the few audio codecs that don't use the sample rate as time base (mp2, mp3). Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpenc_xiph: Don't exclude headers from max_payload_sizeMartin Storsjö2015-02-28
| | | | | | | This makes things more consistent by using the variable in the same way as in all other packetizers. Signed-off-by: Martin Storsjö <martin@martin.st>

* rtpenc_aac: Set a default value for max_frames_per_packet at initMartin Storsjö2015-02-28
| | | | | | | This avoids having to conditionally set the default within the packetizer function. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpenc_amr: Use s->num_frames instead of s->buf_ptr - s->bufMartin Storsjö2015-02-28
| | | | | | | This doesn't fix any bug, but makes the code simpler for later patches, and more straightforward to read as is. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpenc_aac: Fix sending fragmented framesMartin Storsjö2015-02-28
| | | | | | | | | | | | After sending a fragmented frame, len (s->buf_ptr - s->buf) isn't zero, while s->num_frames is zero as intended. Using s->num_frames makes it work as intended, and is less convoluted than keeping track of (resetting) s->buf_ptr. This avoids sending stray data after sending a fragmented aac packet.

* rtpdec: Free depacketizers if the init function failedMartin Storsjö2015-02-24
| | | | | | | | | | | | | | This is different from how it is handled in codecs/demuxers/muxers though (where the close function isn't called if the open function failed), but since the number of depacketizers that have an .init function is quite limited, this is easy to change. The main point is that if the init function failed, we shouldn't try to use that depacketizer at all - this makes sure that the parse function doesn't need to check for the things that were initialized in the init function. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpdec: Don't free the payload context in the .free functionMartin Storsjö2015-02-24
| | | | | | | | | | | | | | This makes it more consistent with depacketizers that don't have any .free function at all, where the payload context is freed by the surrounding framework. Always free the context in the surrounding framework, having the individual depacketizers only free any data they've specifically allocated themselves. This is similar to how this works for demuxer/muxers/codecs - a component shouldn't free the priv_data that the framework has allocated for it. Signed-off-by: Martin Storsjö <martin@martin.st>
