Encoding .png images with h264 to a file on disk
by laddoe 21 Feb '21

21 Feb '21

Hi there, Can somebody help me to find out why I end up with a file on disk that is only 24 kb and not readable by vlc or so, while I send valid YUV images to the codec. I have added the .h and .cpp file. Up till "avcodec_receive_packet" everything seems to be OK. The function call "avcodec_send_frame" returns 0, so that must be OK but "avcodec_receive_packet" returns -11. If I flush the encoder (currently commented) then "avcodec_receive_packet" returns 0 and I can see encoded data if I store it on disk. Also the input image to the encoder is also correct (currently commented) and checked. I'm aiming for an intra-frame encoding, so I should get the encoded frame data back, but I don't get anything back even if I send 24 images to it.

Re-writing hot .ts file that rotates every 24 hours in realtime
by Korn Moffle 20 Feb '21

20 Feb '21

Hello, we have a file that is written in realtime into .ts (MPEG-2). The file is written for 24 hours and then a new file starts. Can we use ffmpeg to: a. copy the file in realtime ? So, ffmpeg would be rewriting file1.ts into file2.ts as file1.ts is constantly being written into. b. tell ffmpeg to read the file with a constant 3 second delay from the most updated frame? c. if a new file appears, detect it and switch to it? Thank you! Sent from Outlook<http://aka.ms/weboutlook>

Muxing Video from Cam1 with Audio from Cam2?
by Steven Kan 20 Feb '21

20 Feb '21

After buying 6 new IP cameras recently, I have suddenly discovered that none of them has a microphone :facepalm: I can’t return them because I’ve done some surgery on them to bypass their 12 V power input diodes, but now I want to stream video from them with audio. I do have a crummy older IP camera laying around that does have audio, but the video quality and features are not what I want. What’s the correct syntax to mux the video from new Cam1 with the audio from older Cam2, while completely discarding the unwanted video from Cam2? Preferably without transcoding anything, since I want to minimize CPU usage. I ran the following command, but it just stalls at time=00:00:09.58 and never returns, and the resulting out.mp4 is an invalid movie with a size of 44 bytes. How do apply “-vn” to Input #1 only? Thanks! ffmpeg -re -thread_queue_size 1024 -rtsp_transport tcp -i "rtsp://anonymous:password1@192.168.1.13:554/cam/realmonitor?channel=1&subtype=0" -i "rtsp://anonymous:password@192.168.1.39:554" -vn -acodec copy -t 00:00:10 out.mp4 ffmpeg version N-100466-g29cef1bcd6-tessus https://evermeet.cx/ffmpeg/ Copyright (c) 2000-2020 the FFmpeg developers built with Apple clang version 11.0.0 (clang-1100.0.33.17) configuration: --cc=/usr/bin/clang --prefix=/opt/ffmpeg --extra-version=tessus --enable-avisynth --enable-fontconfig --enable-gpl --enable-libaom --enable-libass --enable-libbluray --enable-libdav1d --enable-libfreetype --enable-libgsm --enable-libmodplug --enable-libmp3lame --enable-libmysofa --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenh264 --enable-libopenjpeg --enable-libopus --enable-librubberband --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvmaf --enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxavs --enable-libxvid --enable-libzimg --enable-libzmq --enable-libzvbi --enable-version3 --pkg-config-flags=--static --disable-ffplay libavutil 56. 62.100 / 56. 62.100 libavcodec 58.115.102 / 58.115.102 libavformat 58. 65.100 / 58. 65.100 libavdevice 58. 11.103 / 58. 11.103 libavfilter 7. 94.100 / 7. 94.100 libswscale 5. 8.100 / 5. 8.100 libswresample 3. 8.100 / 3. 8.100 libpostproc 55. 8.100 / 55. 8.100 Input #0, rtsp, from 'rtsp://anonymous:password1@192.168.1.13:554/cam/realmonitor?channel=1&subtype=0': Metadata: title : Media Server Duration: N/A, start: 0.100000, bitrate: N/A Stream #0:0: Video: h264 (Main), yuv420p(progressive), 1920x1080, 100 tbr, 90k tbn, 180k tbc Input #1, rtsp, from 'rtsp://anonymous:password@192.168.1.39:554': Metadata: title : Session streamed by "preview" comment : Duration: N/A, start: 0.000000, bitrate: N/A Stream #1:0: Video: h264 (High), yuv420p(progressive), 2560x1440, 29.97 tbr, 90k tbn, 180k tbc Stream #1:1: Audio: aac (LC), 16000 Hz, mono, fltp Output #0, mp4, to 'out.mp4': Metadata: title : Media Server encoder : Lavf58.65.100 Stream #0:0: Audio: aac (LC) (mp4a / 0x6134706D), 16000 Hz, mono, fltp Stream mapping: Stream #1:1 -> #0:0 (copy) Press [q] to stop, [?] for help [rtsp @ 0x7fa887008000] Thread message queue blocking; consider raising the thread_queue_size option (current value: 8) [rtsp @ 0x7fa887008000] max delay reached. need to consume packetx [rtsp @ 0x7fa887008000] RTP: missed 1 packets size= 0kB time=00:00:09.58 bitrate= 0.0kbits/s speed=1.11x

Hello everybody, as I've said before, I am a student and I'm triyng to learn how to use ffmpeg. It is not an easy task, because there is not a lot of documents that explain it in a easy way. I would like to share with you the tools I found useful, and I ask you to reply linking the resourcies and tools you find useful. Hoping to create a list of pages and tools that everybody can use. Here's mine: https://ffmpeg.org/ https://en.wikipedia.org/wiki/FFmpeg https://linux.die.net/man/1/ffmpeg https://wiki.archlinux.org/index.php/FFmpeg http://dranger.com/ffmpeg/ https://wiki.debian.org/ffmpeg https://jsfiddle.net/r6wz0nz6/2/ https://www.binpress.com/generate-video-previews-ffmpeg/ https://www.whoishostingthis.com/compare/ffmpeg/resources/ https://freetoolonline.com/ffmpeg-online.html https://bgrins.github.io/videoconverter.js/demo/ Thanks.

fmpeg exits due to aac error

Hi, I have a very long (24 hour) video stream that I am processing in near realtime. And after a while, ffmpeg exits with the following error: [mpegts @ 0000018aa073f740] PES packet size mismatch [mpegts @ 0000018aa073f740] Packet corrupt (stream = 1, dts = 2733992293). overread 8 [mpeg2video @ 0000018aa2355dc0] Warning MVs not available [mpeg2video @ 0000018aa2355dc0] concealing 6030 DC, 6030 AC, 6030 MV errors in B frame E:\TVRecData\1ch\taskrec_1ch_20210216_121354.ts: corrupt decoded frame in stream 0 [aac @ 0000018aa2353dc0] TYPE_FIL: Input buffer exhausted before END element found Error while decoding stream #0:1: Invalid data found when processing input frame=218550 fps= 30 q=-0.0 Lsize=N/A time=02:01:33.51 bitrate=N/A speed= 1x video:114397kB audio:1366210kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown I am using the following command: fmpeg -err_detect ignore_err -re -sseof -3 -i 20210216_234639.ts -af silencedetect=noise=0.001:d=0.4 -f null - > 20210216_234639.txt 2>&1 Note: the overall file is written is a particular format with several streams, where some streams (EPG, etc) we cannot read. But, we can play the file, and focusing on stream 0 and stream 1 we can get the video and audio. Yet, when reading audio, we get this error. We see a lot of corrupted packets, but strangely, MediaPlayerClassic has no problem playing it. So info is definitely there. Video and audio seem to be ok when playing. I can replay the whole file (including sound) no problem using MediaPlayerClassic, VLC, etc... I am enclosing the whole ffmpeg log for your enjoyment attached to this post. I am stuck and really need help. Thank you! I am also attaching ffprobe output below: (note garbled characters is because it is East Asian language) ffprobe version N-101088-g6f80953554 Copyright (c) 2007-2021 the FFmpeg developers built with gcc 9.3-win32 (GCC) 20200320 configuration: --prefix=/ffbuild/prefix --pkg-config-flags=--static --pkg-config=pkg-config --cross-prefix=x86_64-w64-mingw32- --arch=x86_64 --target-os=mingw32 --enable-gpl --enable-version3 --disable-debug --enable-shared --disable-static --disable-w32threads --enable-pthreads --enable-iconv --enable-zlib --enable-libxml2 --enable-libfreetype --enable-libfribidi --enable-gmp --enable-lzma --enable-fontconfig --enable-opencl --enable-libvmaf --disable-vulkan --enable-libvorbis --enable-amf --enable-libaom --enable-avisynth --enable-libdav1d --enable-libdavs2 --enable-ffnvcodec --enable-cuda-llvm --disable-libglslang --enable-libass --enable-libbluray --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvpx --enable-libwebp --enable-libmfx --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-librav1e --enable-librubberband --enable-schannel --enable-sdl2 --enable-libsoxr --enable-libsrt --enable-libsvtav1 --enable-libtwolame --enable-libuavs3d --enable-libvidstab --enable-libx264 --enable-libx265 --enable-libxavs2 --enable-libxvid --enable-libzimg --extra-cflags=-DLIBTWOLAME_STATIC --extra-cxxflags= --extra-ldflags=-pthread --extra-libs=-lgomp libavutil 56. 65.100 / 56. 65.100 libavcodec 58.123.100 / 58.123.100 libavformat 58. 67.100 / 58. 67.100 libavdevice 58. 11.103 / 58. 11.103 libavfilter 7.106.100 / 7.106.100 libswscale 5. 8.100 / 5. 8.100 libswresample 3. 8.100 / 3. 8.100 libpostproc 55. 8.100 / 55. 8.100 [aac @ 000001d5562aa880] Multiple frames in a packet.

Hi, I had a video that I wanted to convert using this command: > ffmpeg -i INPUT.mkv -c:v libx264 -c:a ac3 -map 0 OUTPUT.mkv But I always got the following error: > Could not write header for output file #0 (incorrect codec parameters > ?): Invalid data found when processing input Reason was, that the start-time and end-time of a chapter was mixed up. It was possible to convert the video with option -map_chapters -1, but I wanted to preserve the chapters. I've extracted the metadata using this: > ffmpeg -i INPUT.mkv -f ffmetadata METADATAFILE I've fixed the chapter times in the metadata file and tried this: > ffmpeg -i INPUT.mkv -i METADATAFILE -map_metadata 1 -c:v libx264 -c:a > ac3 -map 0 OUTPUT.mkv I got the same error as before. The chapter information from input file #1 was listed correctly though. I've even tried it this way like in the example from the documentation: > ffmpeg -i INPUT.mkv -i METADATAFILE -map_metadata 1 -codec copy > OUTPUT.mkv That didn't work either. In the end I had to create a temp file without the corrupt metadata like this: > ffmpeg -i INPUT.mkv -map_chapters -1 -map 0 TEMP.mkv After that I was able to join the fixed metadata I've prepared with this command: > ffmpeg -i TEMP.mkv -i METADATAFILE -map_metadata 1 -c:v libx264 -c:a > ac3 -map 0 OUTPUT.mkv I'm glad it worked but I can't help wondering if there would have been an easier way to do it. Is it possible to fix the chapter time automatically when start-time and end-time are mixed up? Is it possible to make ffmpeg completely ignore the corrupt metadata of input file #0 and just override it with metadata from file #1?
