Michael Niedermayer	e3d95b54db	probe: belive protocol content type if set and avoid lengthly probing. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Mans Rullgard	91ac403b13	lavf: fix arithmetic overflows in avformat_seek_file() The values compared here can be more than INT64_MAX apart. Since the difference is always positive, converting to uint64_t before subtracting gives the correct result without overflows. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Anton Khirnov	cb45553f57	Remove pointless #undefs of previously forbidden functions.	12 years ago
Nicolas George	03847eb825	lavf: compute probe buffer size more reliably. The previous code computes the offset by reversing the growth of the allocated buffer size: it is complex and did lead to inconsistencies when the size limit is reached. Fix trac ticket #1991.	12 years ago
Michael Niedermayer	83ddedbbf2	lavf: the core rfps code needs 2 durations to estimate rfps This fixes a regression where this count became 1 with HPM-GC\ EXPORT\ FCP-1A-AVCI100-1080i25-001.mxf Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Justin Ruggles	261e9348ef	lavf: add a common function for selecting a pcm codec from parameters	12 years ago
Janne Grunau	7709ce029a	lavf: avoid integer overflow in ff_compute_frame_duration() Scaling the denominator instead of the numerator if it is too large loses precision. Fixes an assert caused by a negative frame duration in the fuzzed sample nasa-8s2.ts_s202310. CC: libav-stable@libav.org	12 years ago
Michael Niedermayer	0efcf16a3e	replace av_log(0, by av_log(NULL, The first parameter is a pointer and NULL is more correct Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Carl Eugen Hoyos	d513fb1c75	Add -skip_initial_bytes option. Fixes ticket #1909.	12 years ago
Gavin Kinsey	19660a8876	Allow use of @ character in username and passwords embedded in URLs Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Marton Balint	4bee03034b	lavf: let av_find_best_stream use bitrate info if available I guess the user expects to see the stream with the highest bitrate, not with the most frames, this is especially useful for multi bitrate streams. This patch changes av_find_best_stream to select the stream based on a number of conditions, the first condition has the highest priority, the last condition has the lowest: 1) Select the stream with the highest FFMIN(5, codec_info_nb_frames) value 2) Select the stream with the highest bitrate 3) Select the stream with the highest codec_info_nb_frames 4) Select the first stream Signed-off-by: Marton Balint <cus@passwd.hu> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Michael Niedermayer	2e4ec8947d	lavf: fill in past dts based on reordered pts once the delay becomes known. Previously we had ignored the past dts and just filled in from the point where we have had sufficient information. This should fix Ticket1734 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Stefano Sabatini	bbe9fe469a	lavf/utils: remove loop on AVERROR(EAGAIN) in av_read_frame() The loop was introduced in `64d340c62a`, and was likely breaking non blocking reads as it busy loops.	12 years ago
Anton Khirnov	9eb296572e	lavf: use a malloced AVFrame in try_decode_frame(). This allows using avcodec_free_frame() to free it properly.	12 years ago
