* avcodec/v4l2m2m: allow lower minimum buffer valuesLukas Rusak2023-01-10
| | | | | | | | | There is no reason to enforce a high minimum. In the context of streaming only a few output buffers and capture buffers are even needed for continuous playback. This also helps alleviate memory pressure when decoding 4K media. Signed-off-by: Aman Karmani <aman@tmm1.net>

* lavfi/graphparser: drop a redundant labelAnton Khirnov2023-01-10

* lavfi/graphparser: improve applying graph-level sws optionsAnton Khirnov2023-01-10
| | | | | | | | | | | | | | | | | | The current code will apply them if the options string does not contain a 'flags' substring, and will do so by appending the graph-level option string to the filter option string (with the standard ':' separator). This is flawed in at least the following ways: - naive substring matching without actually parsing the options string may lead to false positives (e.g. flags are specified by shorthand) and false negatives (e.g. the 'flags' substring is not actually the option name) - graph-level sws options are not limited to flags, but may set arbitrary sws options This commit simply applies the graph-level options with av_set_options_string() and lets them be overridden as desired by the user-specified filter options (if any). This is also shorter and avoids extra string handling.
* lavfi/avfilter: process options for filters without a private classAnton Khirnov2023-01-10
| | | | | It still makes sense to apply AVFilterContext-level options to such filters.
* lavfi/avfilter: simplify process_options()Anton Khirnov2023-01-10
| | | | | | | | | | | | This function currently treats AVFilterContext options and filter-private options differently: the former are immediately applied, while the latter are stored in a dictionary to be applied later. There is no good reason for having two branches - storing all options in the dictionary is simpler and achieves the same effect (since it is later applied with av_opt_set_dict()). This will also be useful in future commits.
* lavfi/avfilter: export a multikey dict from process_options()Anton Khirnov2023-01-10
| | | | | This way the function does not need to be able to match keys to AVOptions, which will be useful in future commits.
* lavfi/avfilter: avoid a redundant av_opt_set_dict2() callAnton Khirnov2023-01-10
| | | | | | | Current code first sets AVFilterContext-level options, then aplies the leftover on the filter's private data. This is unnecessary, applying the options to AVFilterContext with the AV_OPT_SEARCH_CHILDREN flag accomplishes the same effect.
* lavfi: remove AVFilter.init_dict()Anton Khirnov2023-01-10
| | | | | | | Nothing uses it anymore. All options on all filters can now be set with normal AVOptions mechanisms, such as av_opt_set*().
* lavfi/vf_scale: allow passing options to swscale directlyAnton Khirnov2023-01-10
| | | | | | Avoid using the dictionary mechanism, which is non-introspectable. As this is the only user of AVFilter.init_dict(), this callback can now be removed.
* fftools/ffmpeg: always generate CFR output when -r is usedAnton Khirnov2023-01-10
| | | | | | | | | | | | | | | | Current code may, depending on the muxer, decide to use VSYNC_VFR tagged with the specified framerate, without actually performing framerate conversion. This is clearly wrong and against the documentation, which states unambiguously that -r should produce CFR output for video encoding. FATE test changes: * nuv-rtjpeg: replace -r with '-enc_time_base -1', which keeps the original timebase. Output frames are now produced with proper durations. * filter-mpdecimate: just drop the -r option, it is unnecessary * filter-fps-r: remove, this test makes no sense and actually produces broken VFR output (with incorrect frame durations).

* mov: Disable advanced_editlist for fragmented MP4 inputDerek Buitenhuis2023-01-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Advanced edit list support is entirely broken for fragmented MP4s, currently. mov_fix_index is never run in mov_build_index, since in fragmented MP4s the stco, stsz, stts, and stsc boxes have zero entries, with the index being filled in as each fragment's trun box is seen. The result of this is that the skip samples is never set properly, since half the code thinks it doesn't need to, as advanced_editlist is enabled, but as mov_fix_index is never called, it doesnt get set. This means that any edits for e.g. priming are not properly applied as skip samples side data. This also means remuxing to fragmented MP4 from progressive MP4 with lavf will quietly drop the edit list, currently. Example: $ ffmpeg -loglevel quiet -advanced_editlist 1 -i non_fragmented.mp4 -f md5 - MD5=d02d929f8eb4edef624758a298d5f7c6 $ ffmpeg -loglevel quiet -advanced_editlist 0 -i non_fragmented.mp4 -f md5 - MD5=d02d929f8eb4edef624758a298d5f7c6 $ ffmpeg -loglevel quiet -advanced_editlist 1 -i fragmented.mp4 -f md5 - MD5=e38b110f586fa886ff94e0ca98a95d59 <-- wrong, extra samples are output instead of being skipped $ ffmpeg -loglevel quiet -advanced_editlist 0 -i fragmented.mp4 -f md5 - MD5=d02d929f8eb4edef624758a298d5f7c6 We cannot call mov_fix_index after reading a trun box since mov_fix_index seems to assume it is only called once, on a fully complete index, an multiple calls to it don't seem like they'd work, so the "best" option seems to be disabling advanced edit list support entirely for the time being, as it is broken for these types of files.
