* asf: don't seek back on EOF.Ronald S. Bultje2012-02-28
| | | | | | | | | Seeking back on EOF will reset the EOF flag, causing us to re-enter the loop to find the next marker in the ASF file, thus potentially causing an infinite loop. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* asf: error out on ridiculously large minpktsize values.Ronald S. Bultje2012-02-28

* segment: implement wrap aroundLuca Barbato2012-02-28
| | | | | | | | Provide a way to wrap around the segment index so pseudostreaming live through a web server and html5 browser is simpler. Also ensure that 0 (disable) is a valid value across the options providing wrap around.

* flvdec: Remove the now redundant check for known broken metadata creatorMichael Niedermayer2012-02-27
| | | | | | The index validation identifies these indexes as broken. Signed-off-by: Martin Storsjö <martin@martin.st>
* flvdec: Validate index entries added from metadata while readingMartin Storsjö2012-02-27
| | | | | | | | | | | By validating the index entries while reading, we don't need to seek at startup to validate the entries. If the error in the index entries is not pointing to (our definition of) the start of packets, and there is an index entry pointing at some of the first packets after the metadata, the invalid index can be discarded almost immediately.

* rtsp: Handle requests from server to clientTommy Winther2012-02-27
| | | | | | | | | | | | This returns 200 OK for OPTIONS requests and 501 Not Implemented for all other requests. Even though this doesn't do much actual handling of the requests, it makes the code properly identify server requests as such, instead of interpreting it as a reply to the client's request as it did before.

* movenc: use timestamps instead of frame_size for samples-per-packetJustin Ruggles2012-02-27
| | | | | | For encoding, AVCodecContext.frame_size is the number of input samples to send to the encoder and does not necessarily correspond directly to the timestamps of the output packets.
* movenc: use the first cluster duration as the tfhd default durationJustin Ruggles2012-02-27

* lavf: don't guess r_frame_rate from either stream or codec timebase.Anton Khirnov2012-02-26
| | | | | | | Neither of those is guaranteed to be connected to framerate in any way (if it even exists). Fixes bug 56.
* lavf: don't set codec timebase in avformat_find_stream_info().Anton Khirnov2012-02-26
| | | | It's not supposed to be set outside of lavc.
* rawdec: set timebase to 1/fps.Anton Khirnov2012-02-26

* matroska: don't overwrite string values until read/alloc was succesful.Ronald S. Bultje2012-02-25
| | | | | | | | | | | | This prevents certain tags with a default value assigned to them (as per the EBML syntax elements) from ever being assigned a NULL value. Other parts of the code rely on these being non-NULL (i.e. they don't check for NULL before e.g. using the string in strcmp() or similar), and thus in effect this prevents crashes when reading of such specific tags fails, either because of low memory or because of targeted file corruption.

* lavf: move the packet keyframe setting code.Anton Khirnov2012-02-24
| | | | | | | | | | compute_pkt_fields() is for unreliable estimates or guessing. The keyframe information from the parser is (at least in theory) reliable, so it should be used even when the other guessing is disabled with the AVFMT_FLAG_NOFILLIN flag. Therefore, move setting the packet keyframe flag based on parser information from compute_pkt_fields() to read_frame_internal().
* oggenc: free comment header for all codecsJustin Ruggles2012-02-24
| | | | | | fixes a memleak for Vorbis and Theora, where the comment header from avpriv_split_xiph_headers() is replaced by a buffer that must be freed separately.

* lavf/output-example: more proper usage of the new API.Anton Khirnov2012-02-24
| | | | Passing the codec into avformat_new_stream() is preferred.

* swf: check return values for av_get/new_packet().Ronald S. Bultje2012-02-23

* rtpenc: Expose the max packet size via an avoptionMartin Storsjö2012-02-23
| | | | | | | | | | This allows opting for a lower MTU than what the AVIOContext indicated, and allows writing into outputs that don't indicate an MTU at all (such as plain files, which is useful for testing). This also allows querying for the MTU via the avoption. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpenc: Move max_packet_size to a context variableMartin Storsjö2012-02-23
| | | | | | This is in preparation for exposing this via an avoption. Signed-off-by: Martin Storsjö <martin@martin.st>

* rtpenc: Allow packetizing H263 according to the old RFC 2190Martin Storsjö2012-02-23
| | | | | | | | | | | | | | | | | | According to newer RFCs, this packetization scheme should only be used for interfacing with legacy systems. Implementing this packetization mode properly requires parsing the full H263 bitstream to find macroblock boundaries (and knowing their macroblock and gob numbers and motion vector predictors). This implementation tries to look for GOB headers (which can be inserted by using -ps <small number>), but if the GOBs aren't small enough to fit into the MTU, the packetizer blindly splits packets at any offset and claims it to be a GOB boundary (by using Mode A from the RFC). While not correct, this seems to work with some receivers. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpenc: Move the trailing comma into FF_RTP_FLAG_OPTSMartin Storsjö2012-02-23

* rm: prevent infinite loops for index parsing.Ronald S. Bultje2012-02-22
| | | | | | | | | Specifically, prevent jumping back in the file for the next index, since this can lead to infinite loops where we jump between indexes referring to each other, and don't read indexes that don't fit in the file.

* lavf: don't set AVCodecContext.has_b_frames in compute_pkt_fields().Anton Khirnov2012-02-22
| | | | | | | | | | | It is not supposed to be done outside lavc. This is basically a revert of 818062f2f346df30f4ec0c0c1f54e8025cc3a80a. It is unclear what issue this was supposed to fix, if it reappears again it will have to be fixed in a more proper place. The wtv-demux test change is because the sample starts with a B-frame.
* rmdec: when using INT4 deinterleaving, error out if sub_packet_h <= 1.Ronald S. Bultje2012-02-22
| | | | | | | | | We read sub_packet_h / 2 packets per line of data (during deinterleaving), which equals zero if sub_packet_h <= 1, thus causing us to not read any data, leading to an infinite loop. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

* movenc: Buffer the mdat for the initial moov fragment, tooMartin Storsjö2012-02-22
| | | | | | | | | | | | This allows writing QuickTime-compatible fragmented mp4 (with a non-empty moov atom) to a non-seekable output. This buffers the mdat for the initial fragment just as it does for all normal fragments, too. Previously, the resulting atom structure was mdat,moov, moof,mdat ..., while it now is moov,mdat, moof,mdat. Signed-off-by: Martin Storsjö <martin@martin.st>

| | | | | | Also split a long line. Signed-off-by: Martin Storsjö <martin@martin.st>
* movdec: Don't parse all fragments if ignidx is setMartin Storsjö2012-02-22
| | | | | | | | | | In nonseekable files, we already stop parsing the toplevel atoms after finding moov and one mdat. In large seekable files (or files that are seekable, but slowly, e.g. http), reading all the fragments at the start can take a considerable amount of time. This allows opting out from this behaviour. Signed-off-by: Martin Storsjö <martin@martin.st>
* movdec: Restart parsing root-level atoms at the right spotMartin Storsjö2012-02-22
| | | | | | | | | | | If parsing moov+mdat in a non-seekable file, we currently abort parsing directly after parsing the header of the mdat atom. If we want to continue parsing later (if looking to parse later fragments), we need to skip past the content of the mdat atom, otherwise we end up parsing the content of the mdat atom as root level atoms.

* movdec: Adjust keyframe flagging in fragmented filesMartin Storsjö2012-02-21
| | | | | | | | | | | | | | For video, mark the first sample in a trun which doesn't have the sample-is-non-sync-sample flag set as a keyframe. In particular, the "sample does not depend on other samples" flag isn't enough to make it a keyframe, since later frames still can reference frames prior to that one (the flag only says that that particular frame doesn't depend on other frames). This fixes bug 215. Signed-off-by: Martin Storsjö <martin@martin.st>
* avcodec: add duration field to AVCodecParserContextJustin Ruggles2012-02-20
| | | | | This will allow parsers to export the duration of the current frame being output, if known, instead of using AVCodecContext.frame_size.
* hls: Reset the AVIOContext when seekingMartin Storsjö2012-02-20
| | | | | | | | This avoids reading any old data in the AVIOContext buffer after the seek, and indicates to the mpegts demuxer that we've seeked, avoiding continuity check errors. Signed-off-by: Martin Storsjö <martin@martin.st>
* applehttp: Do seeking within segments, tooPanagiotis H.M. Issaris2012-02-19
| | | | | | | | | | | Enhance seeking by demuxing until the requested timestamp is reached within the segment selected by the seek code using the playlist info. Some mpegts streams don't have dts set for all packets though, this seeking method doesn't work well for that case. Signed-off-by: Martin Storsjö <martin@martin.st>
