video – FFmpeg/RTSP/h264 – Could not find codec parameters for stream 0

admin

I compiled static FFmpeg to capture a frame from an RTSP stream (from a Hikvision CCTV) to an image. The stream is over TCP can be played using VLC, but I’m having a hard time with FFmpeg since ffmpeg always ended up with Could not find codec parameters for stream 0.

I’ve tried -analyzeduration 10M -probesize 10M yet not making a difference.

Is there any way to solve this?

My x264 config:

--disable-opencl

My FFmpeg configuration:

--disable-everything --disable-autodetect --enable-pic --enable-static --enable-gpl --enable-version3 --enable-libx264 --enable-demuxer=hls --enable-demuxer=rtsp --enable-demuxer=h264 --enable-decoder=h264 --enable-parser=h264 --enable-encoder=mjpeg --enable-muxer=image2 --enable-protocol=pipe --enable-protocol=tcp --enable-protocol=http --enable-decoder=aac --enable-parser=aac --enable-protocol=file --enable-protocol=udp --enable-protocol=rtmp

ffprobe seems manage to decode a frame once a while:
