I've aslo noticed that hls does not support pcm. I want the audio of my hls stream to reflect that of the mkv source:Īlthough what I get returned from the command above gives me no sound and shows me this in mediaInfo: Here is the command I'm using: ffmpeg -i './video.mkv' -ss 00:00:00 -t 00:00:30 -c copy -f hls 'output.m3u8' XMedia Recode can convert almost all known audio and video formats, including 3GP, 3GPP, 3GPP2, AAC, AC3, ADTS, AMR, ASF, AVI, AVISynth, DVD, FLAC, FLV, H.

When playing the output.m3u8 in VLC the option to choose different audio tracks is greyed out. Batch convert, Join files, Converts audio files, Converts photos.

Video converters are computer programs that can change the storage format of digital video. The mkv's by itself play both audio and video fine in VLC. You can help by adding missing items with reliable sources. The next thing I tried was using other mkv videos I have. At one point I replaced -c copy with -acodec aac -ac 6 on the first stream and I got sound which is great but I am only looking to copy the stream and not re-encode it. It's just the first audio stream that does not. I also found that when I point ffmpeg to any other audio stream in the file it works. I have tried using -map to specify the audio stream as well. The source is an mkv with multiple audio tracks. I am using ffmpeg to create an hls stream.

Xmedia recode add audio track to mkv
