Clarify the fact that `encodebasebin->src_pad` is set when using a static source pad (`encodebin`) and when not set it's dynamically added source pads (`encodebin2`). Fixes usage of encodebin2 when profiles are updated Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/6667>

/**
|
|
* SECTION:element-encodebin
|
|
* @title: encodebin
|
|
*
|
|
* EncodeBin provides a bin for encoding/muxing various streams according to
|
|
* a specified #GstEncodingProfile.
|
|
*
|
|
* Based on the profile that was set (via the #GstEncodeBaseBin:profile property),
|
|
* EncodeBin will internally select and configure the required elements
|
|
* (encoders, muxers, but also audio and video converters) so that you can
|
|
* provide it raw or pre-encoded streams of data in input and have your
|
|
* encoded/muxed/converted stream in output.
|
|
*
|
|
* ## Features
|
|
*
|
|
* * Automatic encoder and muxer selection based on elements available on the
|
|
* system.
|
|
*
|
|
* * Conversion of raw audio/video streams (scaling, framerate conversion,
|
|
* colorspace conversion, samplerate conversion) to conform to the profile
|
|
* output format.
|
|
*
|
|
* * Variable number of streams. If the presence property for a stream encoding
|
|
* profile is 0, you can request any number of sink pads for it via the
|
|
* standard request pad gstreamer API or the #GstEncodeBaseBin::request-pad action
|
|
* signal.
|
|
*
|
|
* * Avoid reencoding (passthrough). If the input stream is already encoded and is
|
|
* compatible with what the #GstEncodingProfile expects, then the stream won't
|
|
* be re-encoded but just passed through downstream to the muxer or the output.
|
|
*
|
|
* * Mix pre-encoded and raw streams as input. In addition to the passthrough
|
|
* feature above, you can feed both raw audio/video *AND* already-encoded data
|
|
* to a pad. #GstEncodeBaseBin will take care of passing through the compatible
|
|
* segments and re-encoding the segments of media that need encoding.
|
|
*
|
|
* * Standard behaviour is to use a #GstEncodingContainerProfile to have both
|
|
* encoding and muxing performed. But you can also provide a single stream
|
|
* profile (like #GstEncodingAudioProfile) to only have the encoding done and
|
|
* handle the encoded output yourself.
|
|
*
|
|
* * Audio imperfection corrections. Incoming audio streams can have non perfect
|
|
* timestamps (jitter), like the streams coming from ASF files. #GstEncodeBaseBin
|
|
* will automatically fix those imperfections for you. See
|
|
* #GstEncodeBaseBin:audio-jitter-tolerance for more details.
|
|
*
|
|
* * Variable or Constant video framerate. If your #GstEncodingVideoProfile has
|
|
* the variableframerate property deactivated (default), then the incoming
|
|
* raw video stream will be retimestampped in order to produce a constant
|
|
* framerate.
|
|
*
|
|
* * Cross-boundary re-encoding. When feeding compatible pre-encoded streams that
|
|
* fall on segment boundaries, and for supported formats (right now only H263),
|
|
* the GOP will be decoded/reencoded when needed to produce an encoded output
|
|
* that fits exactly within the request GstSegment.
|
|
*
|
|
* * Missing plugin support. If a #GstElement is missing to encode/mux to the
|
|
* request profile formats, a missing-plugin #GstMessage will be posted on the
|
|
* #GstBus, allowing systems that support the missing-plugin system to offer the
|
|
* user a way to install the missing element.

/* TODO/FIXME
|
|

|
|
* Handling mp3!xing!idv3 and theora!ogg tagsetting scenarios:
|
|
* Once we have chosen a muxer:
|
|
* When a new stream is requested:
|
|
* If muxer isn't 'Formatter' OR doesn't have a TagSetter interface:
