* libvpxenc: add static-thresh private optionAnton Khirnov2014-10-18
| | | | | | | | Currently, this option is accessed through AVCodecContext.mb_threshold, which originally controlled reusing MB data when transcoding mpeg to mpeg. Since the libvpx meaning is completely different from the original mpegvideo meaning, it is better to use a separate private option for this.

* resample: Avoid off-by-1 errors in PTS calcs.Timothy B. Terriberry2014-10-18
| | | | | | | | | | | The rounding used in the PTS calculations in filter_frame() does not actually match the number of samples output by the resampler. This leads to off-by-1 errors in the timestamps indicating gaps and underruns, even when the input timestamps are all contiguous. Bug-Id: 753 Signed-off-by: Anton Khirnov <anton@khirnov.net>

* rtmpproto: Track last received timestampUwe L. Korn2014-10-17
| | | | | | | | Some RTMP commands need the most recent timestamp as their parameter, so keep track of it. This must be the most recent one and not e.g. the max received timestamp as it can decrease again through seeking. Signed-off-by: Martin Storsjö <martin@martin.st>

* libfdk-aacdec: Enable Dynamic Range Control Metadata SupportOmer Osman2014-10-17
| | | | | | | | | | For streams which contain DRC metadata, the FDK decoder is able to control rendering of the decoded output. The rendering parameters are detailed in fdk_aac_dec_options []. The default behavior is left up to the decoder. Signed-off-by: Martin Storsjö <martin@martin.st>
* libfdk-aacdec: Enable Decoder Downmix including Downmix Metadata SupportOmer Osman2014-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | The FDK decoder is capable of producing mono and stereo downmix from multichannel streams. These streams may contain metadata that control the downmix process. The decoder requires an Ancillary Buffer in order to correctly apply downmix in streams containing downmix Metadata. The decoder does not have an API interface to inform of the presence of Metadata in the stream, and therefore the Ancillary Buffer is always allocated whenever a downmix is requested. When downmixing multichannel streams, the decoder requires the output buffer in aacDecoder_DecodeFrame call to be of fixed size in order to hold the actual number of channels contained in the stream. For example, for a 5.1ch to stereo downmix, the decoder requires that the output buffer is allocated for 6 channels, regardless of the fact that the output is in fact two channels. Due to this requirement, the output buffer is allocated for the maximum output buffer size in case a downmix is requested (and also during decoder init). When a downmix is requested, the buffer used for output during init will also be used for the entire duration the decoder is open. Otherwise, the initial decoder output buffer is freed and the decoder decodes straight into the output AVFrame. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtmpproto: Add getStreamLength call to query durationUwe L. Korn2014-10-17
| | | | | | | | | | In (non-live) streams with no metadata, the duration of a stream can be retrieved by calling the RTMP function getStreamLength with the playpath. The server will return a positive duration upon the request if the duration is known, otherwise either no response or a duration of 0 will be returned.

* rtmpproto: Add function to read a number responseUwe L. Korn2014-10-17
| | | | | | | | | Packets that contain a number as a result to a rtmp function call are structured the same way (String, Number, Null, Number). This new method also includes more bounds checks to better handle packets that are not structured as expected. Signed-off-by: Martin Storsjö <martin@martin.st>

* lavc: deprecate the use of AVCodecContext.time_base for decodingAnton Khirnov2014-10-15
| | | | | | | | | | | When decoding, this field holds the inverse of the framerate that can be written in the headers for some codecs. Using a field called 'time_base' for this is very misleading, as there are no timestamps associated with it. Furthermore, this field is used for a very different purpose during encoding. Add a new field, called 'framerate', to replace the use of time_base for decoding.
* vdpau: add AV_HWACCEL_FLAG_IGNORE_LEVEL to skip the codec level checkRémi Denis-Courmont2014-10-15
| | | | | | | | | | | | | Decoding acceleration may work even if the codec level is higher than the stated limit of the VDPAU driver. Or the problem may be considered acceptable by the user. This flag allows skipping the codec level capability checks and proceed with decoding. Applications should obviously not set this flag by default, but only if the user explicitly requested this behavior (and presumably knows how to turn it back off if it fails).

| | | | | | | | | | | These allow getting the absolute start timestamp of a fragment without reading preceding timestamps. This fixes sync between tracks if starting from fragments in different streams that don't align exactly. This also is a prerequisite for producing DASH content.
