Michael Niedermayer	5082fcc0e2	avformat: add support to force specific AVCodecs previously only codec_ids could be forced, which did not allow forcing a specific implementation like libopenjpeg vs jpeg2000.

Michael Niedermayer	8c9d6ee4f2	avformat/utils: functions that add entries should not destroy the whole list on failure The caller does not expect this, and in case of adding new streams would then not even be able to deallocate them anymore. This reverts a hunk from "avformat: Use av_reallocp_array() where suitable" Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Anton Khirnov	26f027fba1	lavf: fix the comparison in an overflow check CC: libav-stable@libav.org Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Clément Bœsch	36cd017acd	avformat: make avformat_close_input() more tolerant. The purpose of this commit is to make error management simpler and less error prone, just like av_free() which is safe with NULL.	11 years ago
Michael Niedermayer	e5c338ba7a	avformat/utils: assert position monotonicity in ff_find_last_ts() This ensures that no read timestamp functions finds packets before the search window in ff_find_last_ts() which could cause an infinite loop Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	a5d67bc796	avformat/utils: Fix bitrate overflow check The check added in `df33a58e53` does not work at all, rather it broke the summing of bitrates completely. The comparission was wrong way around. This commit replaces it by a simpler and hopefully clearer check Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Michael Niedermayer	c5b46a064d	lavf: Don't interpret just slightly broken timestamps as wraparound This avoids breaking some slightly incorrect (dts > pts) timestamps in sample HLS streams from Apple. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	37ecd67b5e	Revert "avformat/utils: Close codec context since it is allocated by avformat_new_stream in refrence to ticket 2716" This causes a race condition with VLC. Its plausible that other applications also would have races with it and its just fixing a memleak when the user application forgets to free the codec. It causes more problems than it solves in its current form, thus the revert. Better solutions are welcome This reverts commit `0f229f9b91`.	12 years ago
Anshul Maheshwari	0f229f9b91	avformat/utils: Close codec context since it is allocated by avformat_new_stream in refrence to ticket 2716 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Martin Storsjö	e740929a07	lavf: Make sure avg_frame_rate can be calculated without integer overflow If either of the deltas is too large for the multiplications to succeed, don't use this for setting the avg frame rate.

Michael Niedermayer	5312c319be	avformat_find_stream_info: fallback to timestamps in analyzeduration check in more cases This fixes speex in rtmp Fixes Ticket2409 the nellymoser in flv case actually needs larger analyzeduration. The code previously just failed to calculate the duration If this causes any problems, like premature analyze/probe end, please report!

Michael Niedermayer	c5ddd75354	avformat_find_stream_info: Do not consider no streams an error in flush codecs This should have no functional effect, but allows a cleaner diff when moving it down Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Carl Eugen Hoyos	2492f7774f	avformat: Print "Consider increasing the value for analzeduration and probesize" even more often The sample from ticket #2691 currently does not trigger "Consider increasing the value for analzeduration and probesize" because the audio streams are only added after calling estimate_timings(). Attached patch moves the message below this function call. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

wm4	e59fb3f8b1	lavf: silence max_analyze_duration warning This is part of normal operation with some formats. A warning should indicate that something is wrong, and the documentation for AV_LOG_WARNING says: "Something somehow does not look correct." Since this message is most likely useful for debugging only, raise the log level accordingly.
