* svq3: Check for any negative return value from ff_h264_check_intra_pred_modeMartin Storsjö2013-09-17
| | | | | | | | Also pass on any returned error code. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* rtmp: rename main_channel_id to stream_id.Josh Allmann2013-09-17
| | | | | | | This more closely corresponds to the usage of the field. Its usage here is unrelated to the channel ID. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtmp: Follow Flash player numbering for channels.Josh Allmann2013-09-17
| | | | | | | | | | | Channel 4 is typically used by the Flash player to transmit audio, channel 6 for video, and various stream-specific invokes get sent over channel 8, which is designated the source channel. This more closely matches the behavior of the Flash player, including the transmission of play requests over channel 8. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtmp: Send video on a separate channel.Josh Allmann2013-09-17
| | | | | | | | | | | Sending non-monotonic packets (e.g. when the audio and video streams are monotonic within themselves but not muxed monotonically) will lead to negative values the RTMP timestamp field (where timestamps are transmitted only as deltas for each channel), and this delta can end up being incorrectly written as a large unsigned number.

* lavf: Make probe_codec return an error codeAlexandra Khirnova2013-09-16
| | | | | | This allows handling errors from av_realloc properly. Signed-off-by: Martin Storsjö <martin@martin.st>
* x86: Add an xmm clobbering wrapper for avcodec_encode_video2Martin Storsjö2013-09-16
| | | | | | | This is required since 187105ff8 when we started trying to wrap this function as well. Signed-off-by: Martin Storsjö <martin@martin.st>
* lavf: Don't explicitly flush after each written packet in muxersClément Bœsch2013-09-16
| | | | | | | | Since 596e5d4783, this is not necessary anymore. It also allows to actually disable the flushing, improving write performance (but possibly giving worse latency in real-time streaming). Signed-off-by: Martin Storsjö <martin@martin.st>
* lavf: Add a flag to enable/disable per-packet flushingLuca Barbato2013-09-16
| | | | | | | | | This is enabled by default and can be disabled with "-fflags -flush_packets". Inspired by a patch from Nicolas George <nicolas.george@normalesup.org>. Signed-off-by: Martin Storsjö <martin@martin.st>
* flv: Do not export datastream as metadataLuca Barbato2013-09-16
| | | | It is used internally.
* rtmp: Store all the notify messagesLuca Barbato2013-09-16
| | | | The onTextData is used to implement text data streams in flv.
* rtmp: Do not send the first field twice within the handshakeLuca Barbato2013-09-16
|
* rtmp: Drop an unneeded warningLuca Barbato2013-09-16
| | | | | Apparently a widely used streaming server requires that the second field always presents a version during C1 phase.
* rtmp: Support play method in listen modeLuca Barbato2013-09-16
|
* rtmp: Factor out publish specific codeLuca Barbato2013-09-16
| | | | Will be reused for supporting play.
* mem: Introduce av_reallocpLuca Barbato2013-09-16

* avpacket: Fix error checking in packet_allocMartin Storsjö2013-09-16
| | | | | | | | | | Previously the wrong buffer pointer was checked, when buf instead of *buf was checked. But checking the return value instead is even better. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>

* proresdec: Properly make sure an index doesn't run past the limitMartin Storsjö2013-09-16
| | | | | | | | | If idx equaled num_coeffs - 1 on entry to the loop, the previous check failed to break out of the loop. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* cavsdec: Make sure a sequence header has been decoded before decoding picturesMartin Storsjö2013-09-16

* vocdec: Don't update codec parameters mid-streamMartin Storsjö2013-09-16
| | | | | | | | | | | | | | | | | | If we really want to support parameter changes, they need to be signalled along with the AVPackets as parameter change side data, not just changing the AVCodecContext parameters when a packet is demuxed (since there may be other earlier packets yet undecoded). Something similar was already done for the sample rate in 0883109b2, but some parameters were left changeable. This avoids having to recheck the channel count for validity for each decoded frame in (ad)pcm decoders, unless the decoders explicitly say that they accept parameter changes.

* sierravmd: Do sanity checking of frame sizesMartin Storsjö2013-09-16
| | | | | | | | | | | Limit the size to INT_MAX/2 (for simplicity) to be sure that size + BYTES_PER_FRAME_RECORD won't overflow. Also factorize other existing error return paths.

* mathops/x86: work around inline asm miscompilation with GCC 4.8.1Hendrik Leppkes2013-09-15

* pcm-dvd: Minor leftoversChristian Schmidt2013-09-13
| | | | Drop a pointless branch in uninit and use the compact copyright.
* pcm-dvd: Support channel configuration changesChristian Schmidt2013-09-13
| | | | | | | | | | The sample buffering logic does not take into account that the blocksize could change. Reset the buffer if the channel configuration changes, since if there are leftover samples, it is most likely a broken or misconcatenated stream. This could lead to negative numbers for missing_samples during decoding. Thanks to Michael Niedermeyer for pointing these out.
