* AVOptions: add new API for enumerating children.Anton Khirnov2011-10-12
| | | | | | | | | This will allow the caller to enumerate child contexts in a generic way and since the API is recursive, it also allows for deeper nesting (e.g. AVFormatContext->AVIOContext->URLContext) This will also allow the new setting/reading API to transparently apply to children contexts.
* flvenc: Write the right metadata entry countMartin Storsjö2011-10-12
| | | | | | | | No application rely on this count being correct as far as I know, but if we write a nonzero count value, it might just as well be the right one. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtsp: Request that dynamic rate is disabledMartin Storsjö2011-10-12
| | | | | | | | | | | | | | | DSS enables this automatically if streaming VOD over TCP. If enabled, the server feeds packets faster than realtime, screwing up RTCP NTP based timestamps. Also, DSS doesn't indicate that this was indicated, if it was enabled automatically (although if it was requested to be enabled, a header saying that it was enabled is added, but this isn't added if it is enabled automatically), making it even harder to detect and work around properly without explicitly asking for it to be disabled(/enabled, if we were able to support it).

* rtpdec: Read the packet length for all RTCP packet typesJohn Brooks2011-10-12
| | | | | | | | | | | This allows skipping past unsupported RTCP packet types, as RFC 3550 section 6.1 mandates. Currently this only has any practical effect if a sender puts an unrecognized type before RTCP_BYE in a compounded packet, or (incorrectly) does not put RTCP_SR first. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpdec: Fix the minimum packet length for RTCP SR packetsJohn Brooks2011-10-12
| | | | | | We actually read 20 bytes of these packets. Signed-off-by: Martin Storsjö <martin@martin.st>
* flvdec: Don't export metadata entries that aren't proper metadataMartin Storsjö2011-10-12
| | | | | | | | | This avoids writing these entries doubly if transcoding from flv to flv, since the muxer blindly writes any and all metadata keys set, in addition to the fixed fields that the muxer always writes. Signed-off-by: Martin Storsjö <martin@martin.st>

* lavf: fix signed overflow in avformat_find_stream_info()Mans Rullgard2011-10-08
| | | | | | | | | | On the first iteration through this code, last_dts is always INT64_MIN (AV_NOPTS_VALUE) and the subtraction overflows in an invalid manner. Although the result is only used if the input values are valid, performing the subtraction is still not allowed in a strict environment. Signed-off-by: Mans Rullgard <mans@mansr.com>

* id3v2: read TXXX frames with two calls to decode_str() instead of one.Anton Khirnov2011-10-03
| | | | | | | Read the key in the first, value in the second. This allows to avoid pointless strdups and simplify decode_str() by dropping two of its parameters.
* id3v2: don't discard the whole tag when encountering empty frames.Anton Khirnov2011-10-03
| | | | | While they're technically invalid, it's better to skip them and try to read the rest of the tag.

* sol: return error if av_get_packet() fails.Justin Ruggles2011-09-25
| | | | This prevents sending a packet with data=NULL size=AVERROR_EOF.
* lavf: do not set codec_tag for rawvideoMans Rullgard2011-09-25
| | | | | | | | | | | | If the demuxer did not set a codec_tag, there is none and inventing one makes no sense. This change stops the rawvideo "decoder" over-writing user-supplied pixfmt with one derived from the codec_tag. The pixfmt-codec_tag-pixfmt round-trip is lossy since several pixfmts map to the same codec_tag. This fixes fate-lavf-pixfmt with avfilter disabled. Signed-off-by: Mans Rullgard <mans@mansr.com>
* flvdec: Check for overflow before allocating arraysMichael Niedermayer2011-09-25
