Can't seek FLAC -> OPUS transcodes in the webUI

awsms commented 4 years ago

Problem description

the opus transcodes i made witth ffmpeg aren't seekable. instead of having a seekable bar, i've the following text: Live Broadcast

Steps to reproduce

put "ffmpeg -i %s -c:a libopus -b:a 96k -f opus -" in the first transcode step, "flac" in convert from, "convert to" opus
enable the previously created transcoder in the Players menu
play any song

System information

Airsonic version: latest snapshot
Operating system: ubuntu 18.04
Java version: openjdk 11.0.8 2020-07-14
Proxy server: nginx
Client: ungoogled-chromium
Language: english

Additional notes

the default FLAC transcode options werks fine and the transcodes are perfectly seekable (ffmpeg -i %s -map 0:0 -b:a %bk -v 0 -f mp3 -)

randomnicode commented 4 years ago

The code checks for the presence of a bitrate variable "%b" in the last stage of the transcode to gauge if it can guess a range.

So try: ffmpeg -i %s -c:a libopus -b:a %bk -f opus - instead of hardcoding a bitrate. Select a bitrate in the client.

Here's the line in the code: https://github.com/airsonic-advanced/airsonic-advanced/blob/d311b152cee54574479f66fcccd98fe9143bcd5b/airsonic-main/src/main/java/org/airsonic/player/service/TranscodingService.java#L539

Thansk! I actually hardcoded this value because I systematically want to transcode @96kbps when I use opus.

Select 96k in the client?

Mind closing the ticket?

I'm now having the exact same issue as https://github.com/airsonic/airsonic/issues/1783#issuecomment-673707549

2020-10-05 15:34:34.873  WARN --- o.a.p.c.StreamController                 : Stream output exceeded expected length of 8075448. It is likely that the transcoder is not adhering to the bitrate limit or the media source is corrupted or has grown larger

While transcoding a 24bit/96kHz FLAC with the following transcode settings:

ffmpeg -i %s -map 0:0 -acodec libvorbis -b:a %bk -f ogg -

So basically, I have the choice between not being able to seek in files, or missing between 5 and 10 seconds on each track?

randomnicode commented 4 years ago

Okay, so we've added some more config options so you can tell the transcoder to get a bigger byte budget when estimating the transcoded file size. Increase your time padding or byte padding in your transcoding settings and you should not have to miss 5 - 10 seconds on each track

Unfortunately, I'm still having the same issue with the latest snapshot, and the playback stops before the last minute of the song. Tried to tweak both bytes and ms values, but still the same.

Tried to tweak both bytes and ms values, but still the same.

What exactly did you "tweak"? What numbers did you provide?

These two lines are telling you exactly what you need:

2020-10-08 12:26:41.595  WARN --- o.a.p.c.StreamController                 : Stream output exceeded expected length of 17448170. It is likely that the transcoder is not adhering to the bitrate limit or the media source is corrupted or has grown larger

2020-10-08 12:26:42.211  INFO --- o.a.p.io.InputStreamReaderThread         : (/opt/airsonic/transcode/ffmpeg) video:0kB audio:17839kB subtitle:0kB other streams:0kB global headers:4kB muxing overhead: 0.690259%

Your final transcode (for that file) is around 17839kb, but your byte budget (estimated) is only 17448170 bytes. Obviously it'll cut off: you have a deficit of around 818966 bytes!

You can add either raw byte counts to your budget or a more dynamic time count.

Let's do some preliminary math:

Let's say this file is y seconds long
Your transcode bitrate you indicated earlier was going to be around 96kbps, but it seems is something different here (200kbps?). Nevertheless, it's x
You know the final transcode is 17839 x 1024 bytes. This is the number you're trying to get to
Your estimated byte budget is: (y + timepaddingInMS / 1000) x 1000 / 8 + rawbytepadding
"Tweak" this equation until you get to (or exceed) your number. You can just add rawbytepadding (if it was 0 before, you need to add about 820000 bytes), or figure out how much timepadding you need to add. The logs should tell you how close your size budget is to the final encode. Use a calculator or trial and error (keep increasing it).
Remember this affects all transcodes, not just for this file, thus the timepadding is usually a better idea (it's more "dynamic")

Note: Here is the expected length formula: https://github.com/airsonic-advanced/airsonic-advanced/blob/9d17b322f7e702a348e4eec3de1d098634e7ce6a/airsonic-main/src/main/java/org/airsonic/player/service/TranscodingService.java#L516-L518
