Empty stream URL

Error message

Empty stream URL

What it means

Thrown by PlaybackResolver.throwResolverExceptionIfUrlNullOrEmpty when the stream URL is an empty string (""). The helper distinguishes null and empty to aid debugging; both are invalid for playback. Called after the stream is expected to have a URL.

Solutions

1. Validate stream.getContent() is non-empty before invoking the resolver.
2. Update/fix the extractor so the content URL is fully populated.
3. Trace where the empty string originates in the StreamInfo build pipeline.

if (stream.getContent() == null || stream.getContent().isEmpty()) {
    // skip stream; do not invoke resolver
}

static boolean hasNonEmptyStreamUrl(final Stream stream) {
    final String c = stream.getContent();
    return c != null && !c.isEmpty();
}

try {
    throwResolverExceptionIfUrlNullOrEmpty(stream.getContent());
} catch (final ResolverException e) {
    // empty content; skip this stream and pick another
}

When it happens

Trigger: throwResolverExceptionIfUrlNullOrEmpty receives an empty ("") String from stream.getContent() on a stream expected to carry a URL. Same call sites as the null case (progressive, DASH-URL, HLS, SS, YouTube progressive/HLS/OTF).

Common situations: The extractor set the content field to an empty string instead of a real URL, a string-processing step trimmed the URL to empty, or the stream was constructed from incomplete parsed data. Indicates a data-quality/extractor issue.
