Minimal ffmpeg build configure RTSP cameras H264 e HEVC

[eusoubrasileiro]

I have been using motion for almost 2 years I guess. I have always built ffmpeg from source due my bad quality IP cameras.
Now I am trying to make a minimal ffmpeg build for motion for SOC (nvidia jetson-nano 2GB)
I only have h264 an hevc cameras. And I am using a custom library for hardware accelerate those (--enable-nvmpi). That makes me include also decoders --enable-decoder=hevc_nvmpi --enable-decoder=h264_nvmpi.

So, I'm trying using the following configure.

./configure --enable-nvmpi --disable-outdevs  --disable-indevs  \
--disable-ffprobe --disable-ffplay --disable-encoders --disable-filters \
--disable-devices --disable-protocols --disable-decoders \
--disable-muxers --disable-demuxers \
--enable-protocol=rtmp \
--enable-encoder=mpeg2video --enable-encoder=mpeg4 \
--enable-muxer=mpeg2video --enable-muxer=mp4 \
--enable-decoder=hevc_nvmpi --enable-decoder=h264_nvmpi \
--enable-muxer=rtsp --enable-muxer=h264 --enable-muxer=hevc --enable-muxer=mp4 \
--enable-demuxer=rtsp --enable-demuxer=h264 --enable-demuxer=hevc  \
--enable-shared --prefix=/usr/local

I am also enabling mpeg2video, mpeg4, mp4 encoders/muxers for timelapse recording.
Everything works fine with ffmpeg command line like to stream through ffmpeg. Like, bellow:

 ffmpeg -v quiet -stats -rtsp_transport tcp -y -c:v  hevc_nvmpi -i rtsp://user:pass@ipcam-kitchen:554/onvif2 -f null -

Unfortunately I'm getting errors with timelapse recording . Saying file exists but I check it doesn't exist. Something like:

Someone knows what else is required I am missing on configure to make timelapse work in this minimal ffmpeg build?

[tosiara]

Never seen that and never tried compiling ffmpeg that way
The only I could suggest is to try compiling ffmpeg in a default way and see if that ever works. Then, try adding your custom flags one by one until you find which one breaks the things

[eusoubrasileiro]

@tosiara thanks you are always willing to help us! Yeah as it is working the default way without problems. It's just a 'branch on my repository' trying to make ffmpeg build faster and optimized.
I will keep on trying that way then. When I finish I will post here the final configure options.

Updating with what works for far.
Note that I only have h264 an hevc RTSP cameras and I use nvpmi library for hardware accelerated decoding.

./configure --enable-nvmpi \
--disable-ffprobe --disable-ffplay \
--disable-outdevs --disable-indevs --disable-devices --disable-filters \
--enable-shared --prefix=/usr/local \
--disable-encoders \
--enable-encoder=mpeg2video --enable-encoder=mpeg4 \
--disable-muxers \
--enable-muxer=mpeg2video --enable-muxer=mp4 --enable-muxer=rtsp \
--enable-muxer=h264 --enable-muxer=hevc --enable-muxer=mp4 \
--disable-decoders \
--enable-decoder=hevc_nvmpi --enable-decoder=h264_nvmpi \
--enable-decoder=hevc --enable-decoder=h264
