# Report The process report captures the log output from FFmpeg. The output is split up in a prelude and log output. The prelude is everything before the first progress line is printed. Everything after that is part of the log. The progress lines are not part of the report. Each log line comes with a timestamp of when it has been captured from the FFmpeg output. The process report helps you to analyze any problems with the FFmpeg command line build from the inputs, outputs, and their options in the process configuration. If the process is running, the FFmpeg logs will be written to the current report. As soon as the process finishes, the report will be moved to the history. The report history is also part of the response of this API endpoint. You can define the number of log lines and how many reports should be kept in the history in the config for the datarhei Core in the [ffmpeg.log](https://docs.datarhei.com/core/configuration/ffmpeg#log) section. The following is an example of a report. ```json { "created_at": 1671109892, "history": [], "log": [ [ "1671111449", "[hls @ 0x7fa31f810240] Opening 'http://admin:xxx@localhost:8080/memfs/f13d9ff4-8ac1-458d-8d61-6e7d8ad06faf.m3u8' for writing" ], [ "1671111449", "[hls @ 0x7fa31f810240] Opening 'http://admin:xxx@localhost:8080/memfs/f13d9ff4-8ac1-458d-8d61-6e7d8ad06faf.mp4' for writing" ], [ "1671111451", "[hls @ 0x7fa31f810240] Opening 'http://admin:xxx@localhost:8080/memfs/f13d9ff4-8ac1-458d-8d61-6e7d8ad06faf_output_0_0778.mp4' for writing" ], [ "1671111451", "[mp4 @ 0x7fa31f80ee40] Opening 'http://admin:xxx@localhost:8080/memfs/f13d9ff4-8ac1-458d-8d61-6e7d8ad06faf_output_0_0768.mp4' for writing" ], [ "1671111451", "[hls @ 0x7fa31f810240] Opening 'http://admin:xxx@localhost:8080/memfs/f13d9ff4-8ac1-458d-8d61-6e7d8ad06faf.mp4' for writing" ], [ "1671111453", "[hls @ 0x7fa31f810240] Opening 'http://admin:xxx@localhost:8080/memfs/f13d9ff4-8ac1-458d-8d61-6e7d8ad06faf_output_0_0779.mp4' for writing" ], [ "1671111453", "[mp4 @ 0x7fa31f80ee40] Opening 'http://admin:xxx@localhost:8080/memfs/f13d9ff4-8ac1-458d-8d61-6e7d8ad06faf_output_0_0769.mp4' for writing" ], [ "1671111453", "[hls @ 0x7fa31f810240] Opening 'http://admin:xxx@localhost:8080/memfs/f13d9ff4-8ac1-458d-8d61-6e7d8ad06faf.m3u8' for writing" ], ... ], "prelude": [ "ffmpeg version 5.1.2 Copyright (c) 2000-2022 the FFmpeg developers", " built with Apple clang version 14.0.0 (clang-1400.0.29.102)", " configuration: --prefix=/usr/local/Cellar/ffmpeg/5.1.2 --enable-shared --enable-pthreads --enable-version3 --cc=clang --host-cflags= --host-ldflags= --enable-ffplay --enable-gnutls --enable-gpl --enable-libaom --enable-libbluray --enable-libdav1d --enable-libmp3lame --enable-libopus --enable-librav1e --enable-librist --enable-librubberband --enable-libsnappy --enable-libsrt --enable-libtesseract --enable-libtheora --enable-libvidstab --enable-libvmaf --enable-libvorbis --enable-libvpx --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxml2 --enable-libxvid --enable-lzma --enable-libfontconfig --enable-libfreetype --enable-frei0r --enable-libass --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libspeex --enable-libsoxr --enable-libzmq --enable-libzimg --disable-libjack --disable-indev=jack --enable-videotoolbox", " libavutil 57. 28.100 / 57. 28.100", " libavcodec 59. 37.100 / 59. 37.100", " libavformat 59. 27.100 / 59. 27.100", " libavdevice 59. 7.100 / 59. 7.100", " libavfilter 8. 44.100 / 8. 44.100", " libswscale 6. 7.100 / 6. 7.100", " libswresample 4. 7.100 / 4. 7.100", " libpostproc 56. 6.100 / 56. 6.100", "Input #0, lavfi, from 'testsrc2=rate=25:size=640x360':", " Duration: N/A, start: 0.000000, bitrate: N/A", " Stream #0:0: Video: rawvideo (I420 / 0x30323449), yuv420p, 640x360 [SAR 1:1 DAR 16:9], 25 tbr, 25 tbn", "Input #1, lavfi, from 'anullsrc=r=44100:cl=stereo':", " Duration: N/A, start: 0.000000, bitrate: 705 kb/s", " Stream #1:0: Audio: pcm_u8, 44100 Hz, stereo, u8, 705 kb/s", "Stream mapping:", " Stream #0:0 -> #0:0 (rawvideo (native) -> h264 (libx264))", " Stream #1:0 -> #0:1 (pcm_u8 (native) -> aac (native))", "Press [q] to stop, [?] for help", "[libx264 @ 0x7fa31ef08540] using SAR=1/1", "[libx264 @ 0x7fa31ef08540] using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4.2 AVX FMA3 BMI2 AVX2", "[libx264 @ 0x7fa31ef08540] profile Constrained Baseline, level 3.0, 4:2:0, 8-bit", "[libx264 @ 0x7fa31ef08540] 264 -
