* lavc/tak: do not store invalid values in stream infoAnton Khirnov2023-05-051-7/+13
| | | | | | | | | | When tak_get_nb_samples() fails, it will currently write AVERROR_INVALIDDATA as TAKStreamInfo.frame_samples. The parser will then use this negative value as a frame duration, which leads to various breakage. Avoid this by returning the error code from tak_parse_streaminfo() directly; never store negative values in the parsed header.

* lavf/dv: use a more granular timebase for audioAnton Khirnov2023-05-021-0/+3
| | | | | | | | | | | | | One that is fine enough to represent all DV audio sample rates. Audio packet durations are now sample-accurate. This largely undoes commit 76fbb0052df471075858c1cb82b04c8be7adba8d. To avoid breaking the issue fixed by that commit, resync audio timestamps against video if they get more than one frame apart. The sample from issue #8762 still works correctly after this commit. Slightly changes the results of the lavf-dv seektest, due to the audio timebase being more granular.
* lavf/dv: do not set video timebase more than onceAnton Khirnov2023-05-021-0/+3
| | | | | | | | | | | | | Current code will call avpriv_set_pts_info() for each video frame, possibly setting a different timebase if the stream framerate changes. This violates API conventions, as the timebase is supposed to stay constant after stream creation. Change the demuxer to set a single timebase that is fine enough to handle all supported DV framerates. The seek tests change slightly because the new timebase is more granular.
