Michael Niedermayer	171dd67520	avformat/mp3dec: optimize mp3_seek() for dir < 0 this minimizes the amount of protocol seeks and reading needed in that case Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	7546ac2fee	avformat/mp3dec: fix start time in light of initial skip samples Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Vittorio Giovara	c0779a67e8	mp3: add .mpa extension Signed-off-by: Diego Biurrun <diego@biurrun.de>	11 years ago
Michael Niedermayer	8d679bc7e6	avformat/mp3dec: improve detection of mp3s with huge id3 tags When a id3 tag is larger than the amount of space we will probe give it a score similar to what a .mp3 extension would have given it Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	1787432b23	mp3dec: make const tables static const Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	e096283ea5	mp3dec: detect CBR and use CBR axiom to seek This should also work reasonable with truncated and growing mp3s. Fixes Ticket2590 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	19d4163331	avformat/mp3dec: read TOC even if not all needed information is available This fixes hyothetical bugs with parsing of elements after the TOC Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	4cc32e5cad	avformat/mp3dec: read xing toc independant of usetoc, only skip filling index if requested Fixes hypothetical parsing bug with -usetoc 0 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	0844630e6b	avformat/mp3dec: Add usetoc option to allow dlsabling the use of the xing TOC The toc is inexact and not using it can thus make sense. Using it is faster though, thus the opposite can similarly makes sense Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Diego Biurrun	e0f8be6413	avformat: Add AVPROBE_SCORE_EXTENSION define and use where appropriate	12 years ago
Michael Niedermayer	505642f182	mp3dec: fallback to generic seeking when a TOC is not present Fixes seeking without a Xing/Info header. CC: libav-stable@libav.org Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago
Alexander Kojevnikov	eae0879d96	mp3dec: Fix VBR bit rate parsing When parsing the Xing/Info tag, don't set the bit rate if it's an Info tag. When parsing the stream, don't override the bit rate if it's already set, otherwise calculate the mean bit rate from parsed frames. This way, the bit rate will be set correctly both for CBR and VBR streams. CC:libav-stable@libav.org Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago

Michael Niedermayer	91295f03d4	mp3dec: remove unused variable Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	b6267901c4	mp3demux: Rewrite xing TOC based seeking The libav code depends on mp3 startcodes only occuring at the start of frames. But there is nothing in mp3 that prevents them occuring elsewhere by chance. Thus the code would fail randomly, the new code searches for 3 consecutive valid frames. If this turns out to be still insufficient the number can be raised further, or additional checks added. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	6d87781758	mp3dec: fix seeking without xing TOC fixes regression from the xing toc support Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Diego Biurrun	0177b7d23a	Improve descriptiveness of a number of codec and container long names	13 years ago
Anton Khirnov	f73e3938ac	mp3dec: forward errors for av_get_packet(). Don't invent a bogus EIO error. The code now doesn't check for ret == 0, but that check is redundant, av_get_packet() never returns 0.	13 years ago
Anton Khirnov	67b1156fe8	mp3dec: remove a pointless local variable.	13 years ago

Reimar Döffinger	7effbee66c	Mark truncated packets as corrupt in av_get_packet. Manually remove that flag again for formats that read an arbitrary amount of data and thus truncation is not an error. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Martin Storsjö	20234a4bd7	cosmetics: Align muxer/demuxer declarations Also add missing trailing commas, break long codec_tag lines and add spaces in codec_tag declarations. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago

Ingo Brückl	c05e2be9a2	mp3dec: Fix reading file size and frames in VBRI headers The fields "Number of Bytes" and "Number of Frames" are mixed up. "Bytes" come first, "Frames" behind.

Clément Bœsch	6a3cc21242	mp3dec: fix truncating packet error message while decoding a complete MP3. The MP3 demuxer split the data in packets of 1024B which are later split in MP3 frames by the MPEG audio parser. The last read is "truncated", but this should not raise any error.

Michael Niedermayer	b51eaf3b8c	mp3probe: Detect mp3 stronger with just 200 frames, this should speed up detection on mp3 streams. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	82ab61f901	lavc: use avpriv_ prefix for some mpegaudio symbols used in lavf. Specifically, ff_mpa_freq_tab, ff_mpa_bitrate_tab, ff_mpa_decode_header, ff_mpegaudio_decode_header.	13 years ago
Anton Khirnov	3b3bbdd3e6	lavf,lavd: replace av_new_stream->avformat_new_stream part I. Trivial replacements with sed are done in this commit: sed 's/av_new_stream(\([^)]*\), 0)/avformat_new_stream(\1, NULL)/'	13 years ago
