- Update build.gradle of demo-transformer module, add dependency:
implementation project(modulePrefix + 'lib-exoplayer-hls')
- Update ConfigurationActivity of demo-transformer module, add hls url:
private static final String[] PRESET_FILE_URIS = {
"https://devstreaming-cdn.apple.com/videos/streaming/examples/bipbop_4x3/bipbop_4x3_variant.m3u8",
...
};
private static final String[] PRESET_FILE_URI_DESCRIPTIONS = { // same order as PRESET_FILE_URIS
"Apple 4x3 basic stream (TS)",
...
}
- Update TransformerActivity of demo-transformer module, set InAppMuxer.Factory:
private Transformer createTransformer(@Nullable Bundle bundle, Uri inputUri, String filePath) {
...
if (!bundle.getBoolean(ConfigurationActivity.ABORT_SLOW_EXPORT)) {
transformerBuilder.setMuxerFactory(new InAppMuxer.Factory(C.TIME_UNSET, null));
}
...
}
- Run demo-transformer, click choose preset file, select Apple 4x3 basic stream (TS), then click the export button.
Expected result
Convert hls stream to MP4.
Actual result

@lyh8577 Thank you for your patience. We have found some suspected root cause for this issue. We are still investigating it. Meanwhile can you please describe you scenario? Are you just trying to convert HLS to and MP4? Or eventually you want to apply some effects as well? If you want to apply some effects as well then the export should just work fine.
@SheenaChhabra I only convert HLS to MP4. Because the Transformer output is MP4, I want to use it as a converter.
Hey @krishnasen2401, We are aiming to fix this issue in 1-2 weeks. We should be able to release this fix in the media3 1.3.1 version which is expected to get released in the first week of April.
Thanks for your patience.
Hey @krishnasen2401, The issue has been fixed now but unfortunately it will be available in next minor release i.e 1.4.0 which is planned to get released in July. I appreciate your patience.
