Re: [FFmpeg-devel] [PATCH] avcodec/aacenc: add strict bit rate control mode

Thanks for the feedback! I was also looking at whether there is a less intrusive way to enable the code path. I have uploaded a v2 patch that looks at `bit_rate_tolerance`, with minor changes to the option table as it was ignored in the context of audio. I'm only looking at the Bluetooth

[FFmpeg-devel] [PATCH v5 5/5] lavfi/format: add a hwmap auto conversion filter

When two formats lists cannot be merged, a scale filter is auto-inserted. However, when it comes to hardware map, we have to manually add a hwmap filter to do the conversion. This patch introduces an auto hwmap filter to do the hwmap conversion automatically. Signed-off-by: Tong Wu ---

[FFmpeg-devel] [PATCH v5 4/5] lavfi/format: wrap auto filters into structures

This patch wraps auto conversion filters into new structures, making it easier to add more auto filters. And it adds a loop to automatically insert every possible conversion filter until merge succeeds. Signed-off-by: Tong Wu --- libavfilter/avfiltergraph.c | 76

When both derive_device_type and device context are not presented during hw->hw map, the hwmap filter should be able to retrieve AVHWDeviceType from outlink->format and create corresponding hwdevice context. Signed-off-by: Tong Wu --- libavfilter/vf_hwmap.c | 35

[FFmpeg-devel] [PATCH v2] avcodec/aacenc: add strict bit rate control option

From: Jeremy Wu In certain use cases, controlling the maximum frame size is critical. An example is when transmitting AAC packets over Bluetooth A2DP. While the spec allows the packets to be fragmented (but UNRECOMMENDED), in practice most headsets do not recognize nor reassemble such packets.
