I have installed the lastest version of ffmpeg on another ubuntu machine. It doesn't output the error message posted before. Rather, I got this message: "Unknown HEVC profile: 0", and the decoding is successful. What does this message mean, please? This is the output (only ffmpeg): ------------------------------------- ffmpeg output ---------------------------- root@odroid:~/bin# ./ffmpeg -i AMP_A_Samsung_6.bit.bin -f null /dev/null ffmpeg version git-2019-01-19-32fb83e Copyright (c) 2000-2019 the FFmpeg developers built with gcc 5.4.0 (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.2) 20160609 configuration: --prefix=/root/ffmpeg_build --pkg-config-flags=--static --extra-cflags=-I/root/ffmpeg_build/include --extra-ldflags=-L/root/ffmpeg_build/lib --extra-libs='-lpthread -lm' --bindir=/root/bin --enable-gpl --enable-libass --enable-libfreetype --enable-libtheora --arch=arm --enable-neon --enable-thumb --enable-optimizations --enable-pthreads --enable-gray --enable-version3 --enable-postproc --enable-libxcb --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-x86asm --enable-nonfree libavutil 56. 26.100 / 56. 26.100 libavcodec 58. 44.100 / 58. 44.100 libavformat 58. 26.100 / 58. 26.100 libavdevice 58. 6.101 / 58. 6.101 libavfilter 7. 48.100 / 7. 48.100 libswscale 5. 4.100 / 5. 4.100 libswresample 3. 4.100 / 3. 4.100 libpostproc 55. 4.100 / 55. 4.100 [hevc @ 0x14bd940] Unknown HEVC profile: 0 Last message repeated 5 times Input #0, hevc, from 'AMP_A_Samsung_6.bit.bin': Duration: N/A, bitrate: N/A Stream #0:0: Video: hevc (Main 10), yuv420p(tv), 2560x1600, 25 fps, 25 tbr, 1200k tbn, 25 tbc [hevc @ 0x14befb0] Unknown HEVC profile: 0 Last message repeated 1 times Stream mapping: Stream #0:0 -> #0:0 (hevc (native) -> wrapped_avframe (native)) Press [q] to stop, [?] for help [hevc @ 0x14befb0] Unknown HEVC profile: 0 Last message repeated 1 times Output #0, null, to '/dev/null': Metadata: encoder : Lavf58.26.100 Stream #0:0: Video: wrapped_avframe, yuv420p, 2560x1600, q=2-31, 200 kb/s, 25 fps, 25 tbn, 25 tbc Metadata: encoder : Lavc58.44.100 wrapped_avframe frame= 60 fps= 30 q=-0.0 Lsize=N/A time=00:00:02.40 bitrate=N/A speed= 1.2x video:24kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown
