[FFmpeg-user] Video and Audio is off-sync on Decklink SDI output
Dear all I am testing to setup a decoder with ffmpeg, take live stream in (RTMP/HLS,.) and output to Decklink SDI. Its working but I have the issue of audio and video is off-sync on decklink SDI output, I tried to play around with vf setpts and af asetpts but couldnt make video/audio to sync. Any input will be very appreciated. Here is my command so far * ffmpeg -i rtmp://something -vf "setpts=PTS-STARTPTS" -af "asetpts=PTS-STARTPTS" -f decklink -pix_fmt uyvy422 "DeckLink SDI" * Video and audio of input rtmp is synced on VLC or other software. --- Best regards, *Tung Tran* ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

Thank you very much Below is my command /opt/ffmpeg/ffmpeg -i 'concat:/farm/files/out/587d0488bb4262d21c8b4577/587d0488bb4262d21c8b4577_part0.3696.kbps.ts|/farm/files/out/587d0488bb4262d21c8b4577/587d0488bb4262d21c8b4577_part1.3696.kbps.ts|/farm/files/out/587d0488bb4262d21c8b4577/587d0488bb4262d21c8b4577_part2.3696.kbps.ts|/farm/files/out/587d0488bb4262d21c8b4577/587d0488bb4262d21c8b4577_part3.3696.kbps.ts' -c copy -hls_time 5 -hls_key_info_file /farm/files/key/587d0488bb4262d21c8b4577.keyinfo -hls_playlist_type vod -hls_segment_filename '/farm/files/out/587d0488bb4262d21c8b4577/587d0488bb4262d21c8b4577_3696kbps_%d.ts' '/farm/files/out/587d0488bb4262d21c8b4577/587d0488bb4262d21c8b4577_3696kbps.m3u8' Log: *ffmpeg stderr: ffmpeg version 3.2.2-static http://johnvansickle.com/ffmpeg/ <http://johnvansickle.com/ffmpeg/> Copyright (c) 2000-2016 the FFmpeg developers* * built with gcc 5.4.1 (Debian 5.4.1-4) 20161202* * configuration: --enable-gpl --enable-version3 --enable-static --disable-debug --disable-ffplay --disable-indev=sndio --disable-outdev=sndio --cc=gcc-5 --enable-fontconfig --enable-frei0r --enable-gnutls --enable-gray --enable-libass --enable-libfreetype --enable-libfribidi --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libopus --enable-librtmp --enable-libsoxr --enable-libspeex --enable-libtheora --enable-libvidstab --enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxvid --enable-libzimg* * libavutil 55. 34.100 / 55. 34.100* * libavcodec 57. 64.101 / 57. 64.101* * libavformat57. 56.100 / 57. 56.100* * libavdevice57. 1.100 / 57. 1.100* * libavfilter 6. 65.100 / 6. 65.100* * libswscale 4. 2.100 / 4. 2.100* * libswresample 2. 3.100 / 2. 3.100* * libpostproc54. 1.100 / 54. 1.100* *Input #0, mpegts, from 'concat:/farm/files/out/587d0488bb4262d21c8b4577/587d0488bb4262d21c8b4577_part0.3696.kbps.ts|/farm/files/out/587d0488bb4262d21c8b4577/587d0488bb4262d21c8b4577_part1.3696.kbps.ts|/farm/files/out/587d0488bb4262d21c8b4577/587d0488bb4262d21c8b4577_part2.3696.kbps.ts|/farm/files/out/587d0488bb4262d21c8b4577/587d0488bb4262d21c8b4577_part3.3696.kbps.ts':* * Duration: 00:00:44.06, start: 1.424067, bitrate: 86635 kb/s* * Program 1 * *Metadata:* * service_name: Service01* * service_provider: FFmpeg* *Stream #0:0[0x100]: Video: h264 (Main) ([27][0][0][0] / 0x001B), yuv420p(progressive), 1920x1080, 29.97 fps, 29.97 tbr, 90k tbn, 59.94 tbc* *Stream #0:1[0x101](eng): Audio: aac (LC) ([15][0][0][0] / 0x000F), 48000 Hz, stereo, fltp, 234 kb/s* *[hls muxer @ 0x53f7800] no key URI specified in key info file* *Could not write header for output file #0 (incorrect codec parameters ?): Invalid argumentStream mapping:* --- Best regards, *Tung Tran* *UNO IPTV* *V247 Enterprise Corp*Phone: 713.358.2257 Bellaire Blvd., Ste. * | *Houston, TX 77036 *tung.t...@v247.com | www.V247.com <http://www.v247.com/>* ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
