* lavf/utils.c Protect against accessing entries[nb_entries]Matt Wolenetz2016-12-30
| | | | | | | | | | | In ff_index_search_timestamp(), if b == num_entries, m == num_entries - 1, and entries[m].flags & AVINDEX_DISCARD_FRAME is true, then the search for the next non-discarded packet could access entries[nb_entries], exceeding its bounds. This change adds a protection against that scenario. Reference: https://crbug.com/666770 Reviewed-by: Sasi Inguva <isasi@google.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* avformat: close parser if codec changedAndreas Cadhalpun2016-11-02
| | | | | | | | | The parser depends on the codec and thus must not be used with a different one.

| | | | | | | | | | | | | in basic computations Allowing larger timestamps makes it impossible to calculate basic things like the difference of 2 timestamps or their sum without checking each individual computation for overflow.

* avformat: prevent triggering request_probe assert in ff_read_packetAndreas Cadhalpun2016-10-19
| | | | | | | | | | | | | If probe_codec is called with pkt == NULL, it sets probe_packets to 0 and request_probe to -1. However, request_probe can change when calling s->iformat->read_packet and thus a probe_packets value of 0 doesn't guarantee a request_probe value of -1. In that case calling probe_codec again is necessary to prevent triggering the assert.

* ffmpeg: switch to codecparClément Bœsch2016-09-21
| | | | | | | | | | | | | | | | | | | | This commit is largely based on commit 15e84ed3 from Anton Khirnov <anton@khirnov.net> which was previously skipped in bbf5ef9d. There are still a bunch of things raising codecpar related warnings that need fixing, such as: - the use of codec->debug in the interactive debug mode - read_ffserver_streams(): it's probably broken now but there is no test - lowres stuff - codec copy apparently required by bitstream filters The matroska references are updated because they now properly forward the field_order (previously unknown, now progressive).

* avformat/utils: Fix find_stream_info not considering the extradata it foundAnssi Hannula2016-07-28
| | | | | | | | | | | | | | | | | | | Commit 9200514ad8717c6 ("lavf: replace AVStream.codec with AVStream.codecpar") merged in commit 6f69f7a8bf6a0d01 changed avformat_find_stream_info() to put the extradata it got from st->parser->parser->split() to st->internal->avctx instead of st->codec (extradata in st->internal->avctx will be later copied to st->codecpar). However, in the same function, the "is stream ready?" check was changed to check for extradata in st->codecpar instead of st->codec, even though st->codecpar is not yet updated at that point. Extradata retrieved from split() is therefore not considered anymore, and avformat_find_stream_info() will therefore needlessly continue probing in some cases. Fix that by checking for the extradata at st->internal->avctx where it is actually put.
