* avformat/argo_brp: remove block_align check for audioZane van Iperen2020-11-05
| | | | | | | | | | | | | | | | | Causes a divide-by-zero in the rare case where: - the file has an audio stream, - the first audio frame isn't within the first BRP_BASF_LOOKAHEAD frames, - an audio frame is encountered later, and - its chunk header (except num_blocks) contains all zeros (matching the uninitialised structure in the context) The decoder will discard any garbage data, so the check isn't really needed.

* avformat/argo_brp: allow v1.1 ASF streams to have a non-22050 sample rate in ↵Zane van Iperen2020-09-27
| | | | | | | | | | | | | | | | certain circumstances It seems that in files where the BASF block isn't first, v1.1 ASF streams are allowed to be non-22050. Either this format is really inconsistent, or FX Fighter and Croc just ignored the sample rate field, requiring the v1.1 restriction in the first place. This bumps the version to 1.2 in these streams so they're not "corrected".

* avformat: add Argonaut Games BRP demuxerZane van Iperen2020-09-14
Used in FMVs for FX Fighter and Croc. Supports BVID and BASF streams, requests samples for anything else. Due to the way BASF streams are contained in the file, only one is supported. I have yet to see a BRP file with multiple. Signed-off-by: Zane van Iperen <zane@zanevaniperen.com>
