* avcodec/decode: Fix leaks upon subtitle decoding errorsAndreas Rheinhardt2021-12-16
| | | | | | | | | | | | | | Up until now, various subtitle decoders have not cleaned up the AVSubtitle on error; this task must not be left to the user because the documentation explicitly states that the AVSubtitle "must be freed with avsubtitle_free if *got_sub_ptr is set" (which it isn't on error). Leaks happen upon failure in ff_ass_add_rect() or in ass_decode_frame(); freeing generically also allows to remove now redundant freeing code in pgssubdec and dvbsubdec. While just at it, also reset got_sub_ptr generically on error. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat/demux: Remove redundant prevention against infinite loopAndreas Rheinhardt2021-12-16
| | | | | | | | | | | | | | | | | | | This piece of code has been added as FFmpeg's answer to infinite loops in try_decode_frame() in commit 6072a19b4f311cb172d45e90daad90824e40e4b6. There is no loop around try_decode_frame() any more, so this code can be removed. This code is only triggered in case a) the codec parameter could not be determined, b) the decode delay could not be guessed or c) no packet was ever encountered and the encoder has the AV_CODEC_CAP_CHANNEL_CONF. In these cases the new code will no longer emit a "decoding for stream %d failed" message, which is prima facie false. In case a) an additional "Could not find codec parameters" message is (and will be) emitted. No warning will be emitted any more in case b) (this happens e.g. with some h264-conformance FATE-files).

* avformat/demux: Remove fake-loopAndreas Rheinhardt2021-12-16
| | | | | | | When flushing, try_decode_frame() itself loops until the desired properties have been found or the decoder is drained. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/h2645_parse: Move ref_idc further up in H2645NALAndreas Rheinhardt2021-12-16
| | | | | | | | This puts it directly near the NALU type which is more natural and furthermore reduces the size of the structure because it can be placed in padding (on 64-bit systems). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

| | | | | | | | | | Forgotten in 03b82b3ab9883cef017e513c7d0b3b986b3b3e7b. (Moving data to the front is only done to make existing initializations like H2645NAL nal = { NULL } not emit int->pointer conversion warnings.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* lavfi/vf_libplacebo: update deprecated option nameNiklas Haas2021-12-15
| | | | | | | | This was renamed upstream quite a while ago (v3.112.0). Rename the option name as well for consistency (and expand the description just slightly). Signed-off-by: Niklas Haas <git@haasn.dev>
* vf_libplacebo: switch to newer libplacebo helpersNiklas Haas2021-12-15
| | | | | | | | | | | | | | | | | Support for mapping/unmapping hardware frames has been added into libplacebo itself, so we can scrap this code in favor of using the new functions. This has the additional benefit of being forwards-compatible as support for more complicated frame-related state management is added to libplacebo (e.g. mapping dolby vision metadata). It's worth pointing out that, technically, this would also allow `vf_libplacebo` to accept, practically unmodified, other frame types (e.g. vaapi or drm), or even software input formats. (Although we still need a vulkan *device* to be available) To keep things simple, though, retain the current restriction to vulkan frames. It's possible we could rethink this in a future commit, but for now I don't want to introduce any more potentially breaking changes.
