Seeking BASS_StreamCreateURL
« on: 8 Feb '19 - 22:59 »
Is there an issue using BASS_ChannelSetPosition with BASS_StreamCreateURL? Maybe I'm doing something wrong. Looking around, it seems this should at least work for seeking back in time.

However trying to use BASS_ChannelSetPosition I get error 37 BASS_ERROR_NOTAVAIL, even when trying to seek to byte 0. BASS_ChannelSeconds2Bytes seems to be returning normal values.

When using StreamCreateURL as a decoding channel to a mixer and seeking the mixer channel, I get error 7 BASS_ERROR_POSITION and no error if seeking to byte 0,  the URL decode channel, I get no error but still the audio does not seek.

if it's a live stream i don't think you can seek it at all.

if it's a file stream seeking is possible only if the BASS_STREAM_BLOCK flag is not used.

I see, this does indeed work as expected for an OGG file URL I found. You're right.

I was hoping this would work for PLEX streams (mp3), I assumed it was a file URL but perhaps its not, or is not working for another reason,

EDIT: I found that downloading the steam to a file on disk while using BASS_StreamCreateFile, and reloading the file when wanting to seek, works fairly well to provide seeking functionality.

I'm out of my league here (I'm no developer!!), but since it wasn't mentioned, are you sure basshls.dll is being called properly??  I say this as its description reads: "An extension enabling the playback of HLS (HTTP Live Streaming) streams. Local media playlists and segments are also supported."  Apologies if that's a non-issue.

Na, calls to basshls.dll are optional, just the plug-in needs to be loaded and the standard bass.dll calls will then work with it automatically.

A BASS_ERROR_NOTAVAIL error from BASS_ChannelSetPosition indicates that seeking is not supported on the stream. If you're not using the BASS_STREAM_BLOCK flag then it is probably that the server didn't send a "Content-Length" header. You can check the HTTP headers with BASS_ChannelGetTags (BASS_TAG_HTTP) to confirm whether that is the case.
