Vittorio Giovara	f22aa6b841	flvdec: avoid unitialized use of a struct member CC: libav-stable@libav.org Bug-Id: CID 718141	10 years ago
Steven Liu	03efd73082	avformat/flvdec: read the correct bits into the tag type from the flv spec, the flvtag define the tagtype as one byte, the spec desc is: Reserved UB[2] Reserved for FMS, should be 0 Filter UB[1] Indicates if packets are filtered. 0 = No pre-processing required. 1 = Pre-processing (such as decryption) of the packet is required before it can be rendered. Shall be 0 in unencrypted files, and 1 for encrypted tags. See Annex F. FLV Encryption for the use of filters. TagType UB[5] Type of contents in this tag. The following types are defined: 8 = audio 9 = video 18 = script data Signed-off-by: Steven Liu <qi.liu@chinacache.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Andrew Stone	0f789322ef	flvdec: update AVFormatContext.event_flags with METADATA_UPDATED whenever metadata changes. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Andrew Stone	93c04e095d	Expose metadata found in onCuePoint events in .flv files. Currently, only onMetaData is used, but some providers (wrongly) put metadata into onCuePoint events, and it's still nice to be able to use that data. onCuePoint events also present metadata slightly differently than onMetaData events: all metadata is found inside an object called "parameters". In order to extract this metadata, it's easiest to recurse through the object tree and pull out anything found in child objects and put it in the top-level metadata.

Uwe L. Korn	a1859032e3	flvdec: Do not default to a video and audio stream If no streams were indicated in the FLV header, do not automatically allocate by default a video and an audio stream. Instead, in the case that the header did not indicate the presence of any data, allocate no stream until data actually arrives for one type.

Benjamin Larsson	547f834537	flv: Workaround for buggy Omnia A/XE encoder The Omnia A/XE encoder writes the explicit extra data incorrectly and wrongly disables parametric stereo. Truncating the extra data by setting the size to 2 works around this. The AAC extra data parser will then only parse the correct parts. Bug-id: 599	11 years ago

Justin Ruggles	e46a2a7309	flvdec: read audio sample size and channels metadata This is needed in order for the FLV demuxer not to detect a codec change when using the "flv_metadata" option.	12 years ago

Martin Storsjö	c5a738ca4e	flvdec: Check the return value of a malloc The callers of this function can't report errors sanely. If this one malloc fails, don't write the extradata byte, make sure we try to malloc it the next time we're called instead, and make sure we still consume the input data byte.

Martin Storsjö	c91c63b538	flvdec: Don't read the VP6 header byte when setting codec type based on metadata This header byte is only present when actually reading a VP6 frame, not when reading the codec type field in the metadata.

Roman Arutyunyan	c0daa73a0f	fix flv new stream handling after head already parsed This fixes stream lookup in flv demuxer. When used with librtmp protocol streams are sometimes added after head arrived. If the first stream added in flv header reader is Audio stream then it is messed with Video stream added later in the code patched. The result is I have 2 Audio streams (first of them is said to have a video codec like h264) instead of Audio/Video pair. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
