Gaullier Nicolas	650ef18078	avformat/utils: better probing for duration in estimate_timings_from_pts() It seems it is more secure to simply duplicate the computing routine from compute_pkt_fields to estimate_timings_from_pts. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	194be1f43e	lavf: switch to AVStream.time_base as the hint for the muxer timebase Previously, AVStream.codec.time_base was used for that purpose, which was quite confusing for the callers. This change also opens the path for removing AVStream.codec. The change in the lavf-mkv test is due to the native timebase (1/1000) being used instead of the default one (1/90000), so the packets are now sent to the crc muxer in the same order in which they are demuxed (previously some of them got reordered because of inexact timestamp conversion).	11 years ago

Michael Niedermayer	1a426d5404	avformat/utils/avformat_find_stream_info: Move max_analyze_duration setup out of the packet loop Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	6f6edfe1c0	avformat/utils: Call ff_rfps_add_frame() only for video This avoids some unneeded computations Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Carl Eugen Hoyos	f284e85714	Report "unknown codec" instead of "unspecifed size" if the codec is unknown.	11 years ago
Carl Eugen Hoyos	6e67852881	Use rc_max_rate in av_find_best_stream() if bitrate == 0. Fixes ticket #2042.	11 years ago
Lazaros Koromilas	0f87b42b44	libavformat/utils: Warning about invalid cover art instead of an error This way other streams can still be used with the -map option. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Michael Niedermayer	e6a084641a	avformat/utils: set max analyze duration depending on the circumstances Fixes Ticket3673 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	52887aa409	avformat: move default for max_analyze_duration into utils.c this way we can do better tha a single fixed constant value Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	c37d179295	avformat: add format_probesize to allow tuning the maximum amount of bytes to identify the filetype Currently probesize is cliped at 1mb before being used for format detection. Alternatively this cliping could be removed but this would then tie various things like stream analysis to the file detection. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Michael Niedermayer	b3b505c73b	avformat/utils: if the id3 tag is too large for data after it to become available, use the full AVPROBE_SCORE_EXTENSION if extension matches Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	d05588e21e	avformat/utils: limit probe score in the id3 case only if there is a chance that data after the id3 tag will become available Fixes ticket3327 (sample.mp3) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Michael Niedermayer	a215b15815	avformat/utils: Set the average frame rate from the r_frame_rate if the stream appears to be cfr This permits the average fps to be set in more cases Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	34e7d3c368	avformat/utils: Ensure that average fps is probed if requested by the user even if tb_unreliable() is 0 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Michael Niedermayer	4394f82f52	avformat/utils: add gif to tb_unreliable() This improves the used timebases when gif is the source Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	1eb57e1d9b	lavc: eliminate tb_unreliable() If framerate estimation is enabled, it makes sense to always apply it, instead of limiting it to a few specific cases.	11 years ago
Anton Khirnov	f9157463db	lavf: do not use the parser duration for video The parser has no way of knowing video duration, and therefore no video parsers set it.	11 years ago
Michael Niedermayer	f3743901d7	avformat: Fix decoder search in find stream info Fixes Ticket3548 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Peter Ross	5331773cc3	ff_id3v2_read: add option to limit ID3 magic number search Several chunked formats (AIFF, IFF,DSF) store ID3 metadata within an 'ID3 ' chunk tag. If such chunks are stored sequentially, it is possible for the ID3v2 parser to confuse the chunk tag for the ID3 magic number. e.g. [1st chunk tag ('ID3 ') \| chunk size] [ID3 magic number \| metadata ...] [2nd chunk tag ('ID3 ') \| chunk size] [ID3 magic number \| metadata ...] Fixes ticket #3530.

Michael Niedermayer	ef818d8bf0	avformat: add av_format_inject_global_side_data(), and disable it by default After this commit applications needs to call av_format_inject_global_side_data() or handle AVStream side data by some other means if they want it not to be lost. This fixes a API incompatibility with libav. libav API does not allow the data to be passed through AVPackets Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
