Is it possible to burn in two .srt files simultaneously to the same file?
by Media Mouth 19 Aug '23

I've got 2 different .srt files and was hoping to use them both simultaneously to create burns in two different locations into the same video. Currently I've got a watermark plus one .srt working just fine. Was hoping to add the additional .srt. The following CLI works just fine (ie Time code & 1 .srt file) ffmpeg -i SourcePath \ -vf 'drawtext=fontsize=15:fontfile=/Library/Fonts/DroidSansMono-webfont.ttf:timecode='01\\:45\\:20\\:13':rate=23.976:fontsize=43.5:fontcolor=white:x=(w-text_w-35):bordercolor=black:borderw=2:y=75, subtitles=${SrtPath1}:force_style='Alignment=4,Fontname=Helvetica,FontSize=12,PrimaryColour=&Hffffff' \ DestPath The following CLI fails (ie Time code & 2 .srt files) ffmpeg -i SourcePath \ drawtext=fontsize=15:fontfile=/Library/Fonts/DroidSansMono-webfont.ttf:timecode='01\\:45\\:20\\:13':rate=23.976:fontsize=43.5:fontcolor=white:x=(w-text_w-35):bordercolor=black:borderw=2:y=75, subtitles=${SrtPath1}:force_style='Alignment=4,Fontname=Helvetica,FontSize=12,PrimaryColour=&Hffffff, subtitles=${SrtPath2}:force_style='Alignment=0,Fontname=Helvetica,FontSize=12,PrimaryColour=&Hffffff \ DestPath The error points to the use of Helvetica font, but since the successful CLI above uses Helvetica as well with no problem, it sounds like a mislead. ffmpeg version 6.0 Copyright (c) 2000-2023 the FFmpeg developers built with Apple clang version 14.0.3 (clang-1403.0.22.14.1) configuration: --prefix=/opt/homebrew/Cellar/ffmpeg/6.0 --enable-shared --enable-pthreads --enable-version3 --cc=clang --host-cflags= --host-ldflags= --enable-ffplay --enable-gnutls --enable-gpl --enable-libaom --enable-libaribb24 --enable-libbluray --enable-libdav1d --enable-libmp3lame --enable-libopus --enable-librav1e --enable-librist --enable-librubberband --enable-libsnappy --enable-libsrt --enable-libsvtav1 --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 --enable-neon libavutil 58. 2.100 / 58. 2.100 libavcodec 60. 3.100 / 60. 3.100 libavformat 60. 3.100 / 60. 3.100 libavdevice 60. 1.100 / 60. 1.100 libavfilter 9. 3.100 / 9. 3.100 libswscale 7. 1.100 / 7. 1.100 libswresample 4. 10.100 / 4. 10.100 libpostproc 57. 1.100 / 57. 1.100 [dnxhd @ 0x159905860] frame size changed: 1920x1088 -> 1920x1080 Guessed Channel Layout for Input Stream #0.1 : mono Input #0, mxf, from 'SourcePath': Metadata: operational_pattern_ul: 060e2b34.04010101.0d010201.01010900 uid : adab4424-2f25-4dc7-92ff-29bd000c0000 generation_uid : adab4424-2f25-4dc7-92ff-29bd000c0001 company_name : FFmpeg product_name : OP1a Muxer product_version_num: 58.29.100.0.0 product_version : 58.29.100 product_uid : adab4424-2f25-4dc7-92ff-29bd000c0002 toolkit_version_num: 58.29.100.0.0 material_package_umid: 0x060A2B340101010501010D0013B02329529471342CB0232900529471342CB000 timecode : 01:45:20:13 Duration: 00:00:28.40, start: 0.000000, bitrate: 37516 kb/s Stream #0:0: Video: dnxhd (DNXHD), yuv422p(bt709/unknown/unknown, progressive), 1920x1080, SAR 1:1 DAR 16:9, 23.98 fps, 23.98 tbr, 23.98 tbn Metadata: file_package_umid: 0x060A2B340101010501010D0013B02329529471342CB0232900529471342CB001 file_package_name: Source Package Stream #0:1: Audio: pcm_s24le, 48000 Hz, 1 channels, s32 (24 bit), 1152 kb/s Metadata: file_package_umid: 0x060A2B340101010501010D0013B02329529471342CB0232900529471342CB001 file_package_name: Source Package Stream mapping: Stream #0:0 -> #0:0 (dnxhd (native) -> mpeg2video (native)) Stream #0:1 -> #0:1 (pcm_s24le (native) -> pcm_s16le (native)) Press [q] to stop, [?] for help [AVFilterGraph @ 0x138e05620] No option name near 'Helvetica' [AVFilterGraph @ 0x138e05620] Error parsing a filter description around: ,FontSize=12,PrimaryColour=&Hffffff [AVFilterGraph @ 0x138e05620] Error parsing filterchain 'drawtext=fontsize=15:fontfile=/Library/Fonts/DroidSansMono-webfont.ttf:timecode='01\:45\:20\:13':rate=23.976:fontsize=43.5:fontcolor=white:x=(w-text_w-35):bordercolor=black:borderw=2:y=75, subtitles=Path/To/TcTest1.srt:force_style='Alignment=4,Fontname=Helvetica,FontSize=12,PrimaryColour=&Hffffff, subtitles=Path/To/TcTest2.srt:force_style='Alignment=10,Fontname=Helvetica,FontSize=12,PrimaryColour=&Hffffff' around: ,FontSize=12,PrimaryColour=&Hffffff Error reinitializing filters!

FFplay: How to show the first frame of a video
by Michael Koch 14 Aug '23

14 Aug '23

Hello, I'd like to make a batch file for FFplay that shows only the first frame of a video until the window is closed. It should also work for still images. This command line works for still images and for most videos, but not for all: ffplay -loop 0 -t 0 -x 500 -an %1 Below is the console output for a video where it doesn't work. I saw these three messages: [mov,mp4,m4a,3gp,3g2,mj2 @ 000001e8bef96180] st: 0 edit list: 1 Missing key frame while searching for timestamp: 1000 [mov,mp4,m4a,3gp,3g2,mj2 @ 000001e8bef96180] st: 0 edit list 1 Cannot find an index entry before timestamp: 1000. [h264 @ 000001e8c4a4fc00] co located POCs unavailable I have two questions: 1. How must the command line be modified to make it work with all videos? 2. Any idea how to show the n_th frame of a video?

looking for paid service for amr transcode on gpu
by Jery soon 08 Aug '23

08 Aug '23

Hi FFmpeg developers, I'm Jim, from a Chinese telecom system provider, Genew Tech, and also a FFmpeg user. We find that transcoding 3gpp amr-nb is the bottleneck of our service. It's currently done on CPU, we want to scale up the transcoding ability by ulitizing CUDA/GPU, it's a cheaper solution for us. So, we want to know the feasibility of transcoding amr-nb on GPU, and we want to hire somebody can do it, please reply me if you are, really appreciate!

Is it possible to create an encrypted DASH stream using ffmpeg only?
by Alexey Rodionov 07 Aug '23

07 Aug '23

Here's a command to create an encrypted HLS stream (see https://stackoverflow.com/a/76815067/4050470) ffmpeg -i input.mp4 -f hls -hls_enc 1 stream.m3u8 And here's a command to create DASH and HLS streams at once: ffmpeg -i input.mp4 -f dash -hls_playlist true manifest.mpd But how to encrypt the stream(s) in this case? As an experiment, I've tried to add to the command the following options: -encryption_scheme cenc-aes-ctr -encryption_key 76a6c65c5ea762046bd749a2e632ccbb -encryption_kid a7e61c373e219033c21091fa607bf3b8 but it has no effect. I would like to avoid using third-party tools like `shaka-packager` and `bento4`.

I’m try using ffmpeg to encode HEVC video in Windows 10 , just like this ffmpeg -ss 10:00 -i test.mkv -to 0:30 -c:v hevc_qsv test2.mkv the ouput file test2.mkv can be played , but it can’t be fast forward or back forward, once use the left key or right key to seek the movie, the video will be frozen. I’ve tried some paras , -idr_interval … They all can’t work. How can I solve this problem My CPU i5-6500 Video card is HD530 Memory 16G 从 Windows 版邮件<https://go.microsoft.com/fwlink/?LinkId=550986>发送
