* avdevice/lavfi: pass forward video framerateTimo Rothenpieler2022-07-18

* avdevice/lavfi: output wrapped AVFramesTimo Rothenpieler2022-07-18
| | | | | | | | | | | | | This avoids an extra copy of potentially quite big video frames. Instead of copying the entire frames data into a rawvideo packet it packs the frame into a wrapped avframe packet and passes it through as-is. Unfortunately, wrapped avframes are set up to be video frames, so the audio frames continue to be copied. Additionally, this enabled passing through video frames that previously were impossible to process, like hardware frames or other special formats that couldn't be packed into a rawvideo packet.

* avdevice/lavfi: Simplify setting sample_fmtsAndreas Rheinhardt2021-12-03
| | | | | | | | | The length of this list is a compile-time constant, so there is no need to calculate it again at runtime. (This also avoids an implicit requirement of -1 == AV_SAMPLE_FMT_NONE.)

* avdevice/lavfi: Don't unnecessarily write '\0' to AVBPrintAndreas Rheinhardt2021-12-03
| | | | | | | | | An AVBPrint's internal string is always already zero-terminated; writing another '\0' is unnecessary as long as one treats the string only as a C-string. Reviewed-by: Nicolas George <george@nsup.org> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avdevice/lavfi: Remove redundant av_packet_unref()Andreas Rheinhardt2020-09-06
| | | | | | | | | Since bae8844e35147f92e612a9e0b44e939a293e5bc9, the AVPacket that is intended to be used to return the demuxed packet is automatically unreferenced when the demuxer returns an error. This makes an av_packet_unref() in the lavfi demuxer redundant. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avdevice/lavfi: Don't set pkt->size to the value it already hasAndreas Rheinhardt2020-09-01
| | | | | | | | | | av_new_packet() already sets the size. And if the packet is not allocated by av_new_packet() (which seems to be impossible atm), both pkt->size as well as size are 0, so setting it again is unnecessary in this scenario, too.
