Attached AAC file cannot be played by the Poweramp. Message: "Failed to play file!" The same file can be played by default android and Huawei musical players. Also there is no issue playing this file on a PC. What is the issue cause? Track 09.aac Link to comment Share on other sites More sharing options...
andrewilley Posted October 1, 2023 Share Posted October 1, 2023 That file plays inconstantly across my various PC players, particularly with regard to duration-related features (it seems to be a VBR file with no specified duration data), and not at all in Poweramp. Max will be able to say more though as to whether the file is badly encoded, and if so whether he can devise a work-around if there are more like it in the wild.

ufedor Posted October 1, 2023 Author Share Posted October 1, 2023 As I wrote there is no issue playing the file on my PC - I'm using VLC. Please note that main problem is that Poweramp refused to play the file - i.e. does not even try... Link to comment Share on other sites More sharing options...
andrewilley Posted October 1, 2023 Share Posted October 1, 2023 When I tried, VLC played the file but had trouble calculating its end-time (the duration kept jumping). Foobar2000 played it but could not seek at all (again, I suspect duration issues). The file is definitely not quite standard (insofar as Apple's AAC format has any documented standard anyway) but Max would be better placed to say why and hopefully create a word-around.

6b6561 Posted October 2, 2023 Share Posted October 2, 2023 I pushed the file through MediaInfo at https://mediaarea.net/MediaInfoOnline. The file is a ADTS stream, probably recorded from a stream, the codec of the audio is AAC LC. Please see https://www.lifewire.com/adts-file-2619508 for some info about ADTS.

6b6561 Posted October 2, 2023 Share Posted October 2, 2023 https://www.lifewire.com/adts-file-2619508 How do I convert an ADTS file to MP3? Use VLC to open and convert ADTS files. Select Media > Convert/Save > Add > find the ADTS file to convert > Open > Convert/Save. From the Convert dialog box, choose MP3 for the conversion format > set a destination for the converted file > and click Save > Start. Link to comment Share on other sites More sharing options...
ufedor Posted October 2, 2023 Author Share Posted October 2, 2023 Still not clear what is the reason for the Poweramp to refuse playing the file while several other payers do not complain. Link to comment Share on other sites More sharing options...
6b6561 Posted October 2, 2023 Share Posted October 2, 2023 It's not a .aac file, the proper extension should be .adts. ADTS is a audio stream protocol used for streaming music over internet and not intended to be listened to locally. Some players such as VLC can handle it.

ufedor Posted October 2, 2023 Author Share Posted October 2, 2023 Are you saying that Poweramp is unable to play such files by design? Are you the Poweramp developer to claim that? Link to comment Share on other sites More sharing options...
andrewilley Posted October 2, 2023 Share Posted October 2, 2023 He is saying this is not a normal AAC file, it appears to be something akin to a capture of an audio stream. Presumably hence the lack of duration information that I noted. Where did you obtain this file, and are there others available from the same source?

6b6561 Posted October 2, 2023 Share Posted October 2, 2023 By pure coincidence I got a similar file earlier today when I was trying to extract a radio stream url. So basically this is what you get when you capture a stream to disk. I'm not a developer and what I have been commenting on is your file which is a adts file and not a plain aac file. Poweramp uses the ffmpeg library to decode files for playback, I had a very quick look at it and I'm not sure if it's supporting adts. This looks pretty much like what you see when you capture video streams which are often in some stream transport format and must be re-muxed into a normal mp4 container better suitable for local playback. My strong recommendation is that you use VLC and convert the file to AAC, should be lossless as the audio stream in the adts file is AAC. Link to comment Share on other sites More sharing options...
ufedor Posted October 3, 2023 Author Share Posted October 3, 2023 How can you explain the fact that attached track is played flawlessly by the Poweramp? Track 01.aac Link to comment Share on other sites More sharing options...
MotleyG Posted October 3, 2023 Share Posted October 3, 2023 Both files are adts format, and simply stored in an aac container. While neither are typical aac files, there seems to be enough info in the second file to play that doesn’t exist in the first example. I guess the bigger question is what the original source was for these files. If possible I would try to get these in a more widely usable type for players to be able to use. Poweramp is designed first and foremost as a local music player. Link to comment Share on other sites More sharing options...
ufedor Posted October 3, 2023 Author Share Posted October 3, 2023 Both files were produced by the EZ CD Audio Converter. Exactly the same conversion settings were used. Link to comment Share on other sites More sharing options...
maxmp Posted October 3, 2023 Share Posted October 3, 2023 @ufedor thanks for the file. Large id3v2 image caused adts desync. I added support for raw aac files with id3v2 tag like this to the next build. You can make it playable in the current Poweramp builds by removing album art images or for example, changing it to somewhat else (currently the image takes 5mb of 8.9 mb aac file and is not that high quality anyway, but it's not the most extreme case I've seen).
