Public Member Functions | |
FLVParser (std::auto_ptr< IOChannel > lt) | |
Create an FLV parser reading input from the given IOChannel. | |
~FLVParser () | |
Kills the parser... | |
virtual bool | seek (boost::uint32_t &) |
Seeks to the closest possible position the given position, and returns the new position. | |
virtual bool | parseNextChunk () |
Parse next chunk of input. | |
boost::uint64_t | getBytesLoaded () const |
Return number of bytes parsed so far. | |
bool | indexingCompleted () const |
Return true of indexing is completed. | |
virtual void | fetchMetaTags (OrderedMetaTags &tags, boost::uint64_t ts) |
Retrieve any parsed metadata tags up to a specified timestamp. | |
Static Public Attributes | |
static const size_t | paddingBytes = 8 |
The size of padding for all buffers that might be read by FFMPEG. |

gnash::media::FLVParser::FLVParser | ( | std::auto_ptr< IOChannel > | lt | ) |
Create an FLV parser reading input from the given IOChannel.
lt | IOChannel to use for input. Ownership transferred. |
References gnash::media::MediaParser::startParserThread().
gnash::media::FLVParser::~FLVParser | ( | ) |
Kills the parser...

void gnash::media::FLVParser::fetchMetaTags | ( | OrderedMetaTags & | tags, |
boost::uint64_t | ts | ||
) | [virtual] |
Retrieve any parsed metadata tags up to a specified timestamp.
This copies pointers to a SimpleBuffer of AMF data from _metaTags, then removes those pointers from the MetaTags map. Any metadata later than the timestamp is kept until fetchMetaTags is called again (or the dtor is called).
ts | The latest timestamp to retrieve metadata for. |
tags | This is filled with shared pointers to metatags in timestamp order. Ownership of the data is shared. It is destroyed automatically along with the last owner. |

boost::uint64_t gnash::media::FLVParser::getBytesLoaded | ( | ) | const [virtual] |
Return number of bytes parsed so far.

References gnash::media::MediaParser::_bytesLoadedMutex, and gnash::media::MediaParser::_bytesLoaded.
bool gnash::media::FLVParser::indexingCompleted | ( | ) | const [inline, virtual] |
Return true of indexing is completed.
If this function returns false, parseNextChunk will be called even when buffers are full. Parsers supporting indexing separated from parsing should override this method and have parseNextChunk figure if they only need to index or to parse based on bufferFull.
Reimplemented from gnash::media::MediaParser.
bool gnash::media::FLVParser::parseNextChunk | ( | ) | [virtual] |
Parse next chunk of input.
The implementations are required to parse a small chunk of input, so to avoid blocking too much if parsing conditions change (ie: seek or destruction requested)
When LOAD_MEDIA_IN_A_SEPARATE_THREAD is defined, this should never be called by users (consider protected).
Implements gnash::media::MediaParser.
References gnash::media::MediaParser::bufferFull().
bool gnash::media::FLVParser::seek | ( | boost::uint32_t & | time | ) | [virtual] |
Seeks to the closest possible position the given position, and returns the new position.
time | input/output parameter, input requests a time, output return the actual time seeked to. |
Implements gnash::media::MediaParser.

const size_t gnash::media::FLVParser::paddingBytes = 8 [static] |
The size of padding for all buffers that might be read by FFMPEG.
This possibly also applies to other media handlers (gst). Ideally this would be taken from the current Handler, but we don't know about it here.
