* pcm_dvd: consolidate pieces from pcm.c and mpeg.cChristian Schmidt2013-08-31
| | | | | | | | | | | | | | | | | | | | Remove the header decoding for PCM audio from mpeg.c and the 20/24bit parts from pcm.c and merge them into a new decoder in pcm-dvd.c. The decoder has added support for samples that span multiple packets and modified 20/24bit group decoding. Both is needed to decode samples that have been generated with DVD-Lab Pro 2. The decoding of 16bit PCM and two channel 24bit is identical to before. No other samples are known to verify the correctness of the encoding this software does. The complete list of tested formats is 48kHz/16bit/2-8 channels 48kHz/24bit/2-5 channels 96kHz/16bit/2-4 channels 96kHz/24bit/2 channels Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* rtmpproto: Fix limelight authentication with abbreviated app namesMartin Storsjö2013-08-28
| | | | | | | | | When streaming to limelight, the app name is either a full "appname/subaccount" or "appname/_definst_". In the latter case, the app name can be simplified into simply "appname", but the authentication hashing assumes the /_definst_ still to be present. Signed-off-by: Martin Storsjö <martin@martin.st>
* smoothstreamingenc: Write to a temp file while updating the manifestMartin Storsjö2013-08-27
| | | | | | | | If a client tries to read the file while it's being updated, the client would get an incomplete manifest. Instead write to a separate temp file and atomically rename it to replace the previous one. Signed-off-by: Martin Storsjö <martin@martin.st>

* matroskaenc: Fix writing TRACKDEFAULTFLAGJohn Stebbins2013-08-27
| | | | | | | | The element was only being written when the value == 1. But the default value of this element is 1, so this has no useful effect. This element needs to be written when the value == 0. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* movenc: Check for errors from mov_create_chapter_trackMartin Storsjö2013-08-27
| | | | | | | | | | | On failures in the write_trailer function, we could also ignore the errors and try to finish the file despite these errors (which would only leave an incomplete chapters track). It's probably better to signal the error clearly to the caller though (and if this function failed there's no guarantee that there's enough memory to finish the trailer either).

* movenc: Make tkhd "enabled" flag QuickTime compatibleJohn Stebbins2013-08-23
| | | | | | | | QuickTime will play multiple audio tracks concurrently if this flag is set for multiple audio tracks. And if no subtitle track has this flag set, QuickTime will show no subtitles in the subtitle menu. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* movenc: add faststart option for web streamingClément Bœsch2013-08-21
| | | | | | | Faststart moves the moov atom to the beginning of the file and rewrites the rest of the file after muxing is complete. Signed-off-by: Martin Storsjö <martin@martin.st>
* movenc: Allow chapters to be written in trailerJohn Stebbins2013-08-20
| | | | | | | | This allows creation of frame accurate chapter marks from sources like DVD and BD where the precise chapter location is not known until the chapter mark has been reached during reading. Signed-off-by: Martin Storsjö <martin@martin.st>

* mkv: Allow flushing the current cluster in progressMartin Storsjö2013-08-19
| | | | | | | | Allow emitting the current cluster that is being written before starting a new one, simplifying how to figure out where clusters are positioned in the output stream (for live streaming). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* movenc: Indicate that negative timestamps are supportedMartin Storsjö2013-08-17
| | | | | | | | | | | | | The mov/mp4 muxer has support for handling negative timestamps via edit lists (which customarily is used for handling the 1-frame delay due to B-frames as well). Using the muxer's native way of handling it is better than using the generic offsetting. The generic offsetting is a bit too crude when e.g. the timebase of one track is 1/fps, where the edit lists can handle it accurately. Signed-off-by: Martin Storsjö <martin@martin.st>
* hlsenc: Don't reset the number variable when wrappingCarl Eugen Hoyos2013-08-15
| | | | | | | | The counter itself shouldn't be wrapped, since it is used for determining end_pts for the next segment - only wrap the number used for the segment file name. Signed-off-by: Martin Storsjö <martin@martin.st>
* hlsenc: Append the last incomplete segment when closing the outputStefano Sabatini2013-08-15
| | | | | | | Also avoid comparing NOPTS values. Bug-id: 551 Signed-off-by: Martin Storsjö <martin@martin.st>
* hlsenc: Add a proper dependency on the mpegts muxerMartin Storsjö2013-08-15
| | | | | | | | | The hls muxer itself doesn't have any direct (object file level) dependencies on mpegtsenc.o, and including that object file directly doesn't ensure that it is registered so that the muxer actually is accessible. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpproto: Check the right feature detection macroMartin Storsjö2013-08-15
| | | | | | | | IPPROTO_IPV6 is unrelated here (it's only used in udp.c for multicast sockopts), check for support for the sockaddr_in6 struct itself. Signed-off-by: Martin Storsjö <martin@martin.st>

* sdp: Add an option for sending RTCP packets to the source of the last packetsMartin Storsjö2013-08-14
| | | | | | | | | | | | | | | | | | | An SDP description normally only contains the target IP address and port for the packets. This means that we don't really have any clue where to send the RTCP RR packets - previously they're sent to the destination IP written in the SDP (at the same port), which rarely is the actual peer. And if the source for the packets is on a different port than the destination, it's never correct. With a new option, we can choose to send the packets to the address that the latest packet on each socket arrived from. --- Some may even argue that this should be the default - perhaps, but I'd rather keep it optional at first. Additionally, I'm not sure if sending RTCP RR directly back to the source is desireable for e.g. multicast. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpproto: Add an option for writing return packets to the address of the ↵Martin Storsjö2013-08-14
| | | | | | | | | | | last received packets If we've received packets on the same socket before, the return packets are sent to that address. If we've only received packets on the other socket, try to guess the source port for the other one assuming the basic +1/-1 logic. Signed-off-by: Martin Storsjö <martin@martin.st>
