2012-01-31lavf: remove the pointless value field from flv and iv8Anton Khirnov
The demuxers don't use it in any way.
2012-01-31flvdec: Interpret a toplevel 'object' type metadata item as normal metadata, tooMartin Storsjö
Previously, we've only passed the key string on to the recursive amf_parse_object for the mixedarray type, not for 'object'. By passing the key string on, the recursive amf_parse_object can store the amf objects as metadata. This kind of data was seen in data from XSplit Broadcaster, received over RTMP via Wowza. This patch allows reading this metadata. Signed-off-by: Martin Storsjö <martin@martin.st>
2012-01-27lavf: remove AVFormatParameters from AVFormatContext.read_header signatureAnton Khirnov
2012-01-05flvdec: Fix compiler warning for uninitialized variablesJean First
These can't be used uninitialized in practice, but the compiler doesn't realize it. Signed-off-by: Martin Storsjö <martin@martin.st>
2011-12-22flvdec: Add param change side data if the sample rate or channels have changedMartin Storsjö
Signed-off-by: Martin Storsjö <martin@martin.st>
2011-12-22flvdec: Export new AAC/H.264 extradata as side data on the next packetMartin Storsjö
Compared to just overwriting the old extradata, this has the advantage of letting the decoder know exactly when the extradata changed (otherwise it is changed immediately when the new extradata packet is demuxed, even if there's old queued packets awaiting to be decoded). This makes it easier for decoders to actually react to the change, so they won't have to inspect the extradata for each packet to see if it might have changed. This works when sequentially playing a file with sample rate changes, but if seeking past a new extradata packet in the file, it obviously doesn't work properly. That case doesn't work in flash player either, so it's probably ok not to handle it. Signed-off-by: Martin Storsjö <martin@martin.st>
2011-12-11lavu: replace int/float punning functionsMans Rullgard
The existing functions defined in intfloat_readwrite.[ch] are both slow and incorrect (infinities are not handled). This introduces a new header with fast, inline conversion functions using direct union punning assuming an IEEE-754 system, an assumption already made throughout the code. The one use of Intel/Motorola extended 80-bit format is replaced by simpler code sufficient under the present constraints (positive normal values). The old functions are marked deprecated and retained for compatibility. Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-12-03latmdec: fix audio specific config parsingJanne Grunau
Pass the correct size in bits to mpeg4audio_get_config and add a flag to disable parsing of the sync extension when the size is not known. Latm with AudioMuxVersion 0 does not specify the size of the audio specific config. Data after the audio specific config can be misinterpreted as sync extension resulting in random and wrong configs.
2011-11-30lavf: make av_set_pts_info private.Anton Khirnov
It's supposed to be called only from (de)muxers.
2011-10-22flvdec: Do not call parse_keyframes_index with a NULL streamReimar Döffinger
Signed-off-by: Martin Storsjö <martin@martin.st>
2011-10-20lavc: use avpriv_ prefix for some mpeg4audio symbols used in lavf.Anton Khirnov
Specifically, ff_mpeg4audio_sample_rates, ff_mpeg4audio_get_config and ff_copy_pce_data
2011-10-19lavf: replace av_new_stream->avformat_new_stream part II.Anton Khirnov
Manual replacements are done in this commit. In many cases, the id is some constant made up number (e.g. 0 for video and 1 for audio), which is then not used in the demuxer for anything. Those ids are removed.
2011-10-12flvdec: Don't export metadata entries that aren't proper metadataMartin Storsjö
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>
2011-10-12flvdec: Split out setting of numeric fields from storing metadataMartin Storsjö
Signed-off-by: Martin Storsjö <martin@martin.st>
2011-09-25flvdec: Check for overflow before allocating arraysMichael Niedermayer
On allocation, the array length is multiplied by sizeof(int64_t), this prevents the multiplication from overflowing. Signed-off-by: Martin Storsjö <martin@martin.st>

2011-07-17lavf: use designated initialisers for all (de)muxers.Anton Khirnov
It's more readable and less prone to breakage.

2011-05-18flvdec: clenup debug codeAlex Converse
2011-04-13flvdec: Allow parsing keyframes metadata without seeking in most casesMartin Storsjö
Stop the avio input at a point where amf_parse_object can continue parsing the end of the object seamlessly, when all data is available. If unsupported data is encountered within the keyframes object, try seeking to the start of the keyframes object - if the seek back was successful, the caller can continue parsing the rest of the AMF data. Signed-off-by: Martin Storsjö <martin@martin.st>
2011-04-12avio: undeprecate av_url_read_fseek/fpause under nicer namesAnton Khirnov
It seems their replacements won't be ready anytime soon.
2011-04-12flvdec: Fix support for flvtool2 "keyframes based" generated indexKharkov Alexander
Current keyframes data parser unconditionally rewind metadata to the end at the end of function. As result ALL metadata located after keyframes index not parsed, and as metadata object can have ANY placement inside metadata it can lead to unpredictable result (bitrate can not be found, etc.). As result FLV movie will not play at all in such situation. Signed-off-by: Martin Storsjö <martin@martin.st>
2011-04-04flvdec: fix segfault in amf_parse_object() due to NULL keyJustin Ruggles
fixes Issue 2674
2011-04-04avio: introduce an AVIOContext.seekable fieldAnton Khirnov
Use it instead of url_is_streamed and AVIOContext.is_streamed.
2011-03-31flvdec: read index stored in the 'keyframes' tag.Kharkov Alexander
'keyframes' metatag is not part of the standard, it is just convention to use such kind of metatag information for indexing. Structure is following, it allows to have it inconsistent: keyframes: times (array): time0 (num) time1 (num) time2 (num) filepositions (array) position0 (num) position1 (num) Signed-off-by: Anton Khirnov <anton@khirnov.net>

In the name of consistency: get_byte -> avio_r8 get_<type> -> avio_r<type> get_buffer -> avio_read get_partial_buffer will be made private later get_strz is left out becase I want to change it later to return something useful. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

2011-01-27Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice.Diego Elio Pettenò
This also lists the objects from those two libraries as internal (by adding the ff_ prefix) so that they can then be hidden via linker scripts.

2010-04-18Implement librtmp seek support.Howard Chu
Implement flv_read_seek(), add a missing check on stream_index and fix timestamp rounding in rtmp_read_seek(). Also add the flv_read_seek2() function, which is not enabled but is useful as reference. To actually implement flv_read_seek2() correctly, there would need to be some corresponding av_url_read_fseek2() function to propagate the timestamps down to the ByteIOContext and URLContext.
