vpp_rkrga filter causes hang and memory leak when using drm_prime

@nyanmisaka commented on GitHub (Nov 12, 2025):

There are thousands of users running the same commands here. If such a significant leak were to occur, I couldn't possibly have missed it…

请问3588用当前的ffmpeg编码4kp60的nv12数据成h264,cpu消耗很高,把一个核占满了,但用是mpp_enc_test 测试编码消耗的cpu不到%4,这个怎么解决?

@nyanmisaka commented on GitHub (Nov 9, 2025):

The v4l2 device input in ffmpeg does not support zero-copy, meaning it cannot output AV_PIX_FMT_DRM_PRIME. I don't have time to work on this right…

Can it be used on the RV1126 chip?

@wgsP commented on GitHub (Oct 31, 2025):

It runs very well on the rv1126 device (since testing these days). My device is ARMv7, so I need to compile MPP, RGA, and FFmpeg for ARMv7. The code used…

编码开始延迟一帧输出

@changliwu commented on GitHub (Oct 9, 2025):

h265编码时,我这样设置的 av_opt_set(m_pRKEncodecCtx->priv_data,"flags","+low_delay",0),但是输出没起作用,请问哪里有问题吗?

@nyanmisaka commented on GitHub (Oct 31, 2025):

That's great. My concern was about the memory allocator MPP used on RV series.

@nyanmisaka commented on GitHub (Oct 29, 2025):

I don't think so. The RV series uses a special version of MPP, which might be incompatible with this. I have no experience using those chips;…

No, it doesn't. Most of FFmpeg's hardware encoders only support setting encoding parameters during the init phase. To change it you need to reinit…

Use -flags +low_delay to disable async encoding.
