![]() Is there some way to tell ffmpeg to use the last 1024 frames from the previously-encoded MP3 (e.g., radio-12344. Here's the ffmpeg I've got so far encoding from WAV files that we write to a temp folder on disk in advance of this step: ffmpeg \ Losslessly rearrange the order of video/audio segments. hi, iam trying to encode rtsp streaming from ffmpeg and decode it in vlc player. See this answer to this question on video StackExchange: LosslessCut aims to be the ultimate cross platform FFmpeg GUI for extremely fast and lossless. However, when I perfectly replicate the output of that ffmpeg -f hls process above using manual ffmpeg runs, we hear audio discontinuities, tiny pieces of silent mortar between the bricks of audio. Ideally, I can consume that stream using ffplay without errors. ![]() FFmpeg can help with this situation: ffmpeg -i input.webm -c:v copy -c:a flac output.mkv. hls_segment_filename /tmp/radio-%d.mp3 \ It can be very time consuming to re-encode the correct stream. for YouTube, then I suggest to split the process to. ffmpeg: outputargs: - record: -f segment -segmenttime 10. If you just want to embed a cover you might consider keeping the result as mp3, for example: ffmpeg -i original.mp3 -i cover.png -map 0:0 -map 1:0 -metadata:s:v title'Album cover' -metadata:s:v comment'Cover (Front)' -id3v2version 3 -writeid3v1 1 result.mp3. I've gotten a test version working with ffmpeg running inside of another process that feeds PCM data to its stdin: ffmpeg \ Note the use of -c:a copy which enables stream copy mode so your MP3 does not get re-encoded to avoid generation loss.-ss and -t or -to. When using -c:a aac, do not forget to replace -c copy with -c:v copy. Furthermore, the audio stream is MP3-encoded so you need to enable LAME support. In a perfect world, the catch is that to support high fault tolerance, these MP3 files are all individually generated from the source WAV files. ffmpeg -i INPUT -map 0 -c copy -c:v:1 libx264 -c:a:137 libvorbis OUTPUT. I'm shipping a 24/7 live HLS stream with only MP3 files. ![]() I've abstracted the real-world constraints into a toy problem for simplicity, but these constraints are real for me. My use case is essentially DIY internet radio. ![]()
