Hello. Please check the playback URL for typos. It looks like you have .mp4.mp4 as the extension: ```auto BBB_Main_10s_deu_20_12000k-HEVC-4K[B].mp4.mp4[/B] ``` Regards, Salvadore ---

If you are trying to access files in a sub folder of the /content folder, for example /content/dt/your-file.mp4 toy will need to include **_definst_** in the playback URL. For example: ```auto [[I]protocol[/I]]://[[I]ip-address[/I]]:1935/vod/_definst_/mp4:[[I]sub-folder-name[/I]]/mp4:[[I]some-file[/I]].mp4 ``` Regards, Salvadore ---

Support for h.265 was added to Wowza 4.1.0 but only as a preview. Assuming you are running Wowza 4.1.0 or higher, you can transcode an incoming h.265 stream as well as record the live stream for VOD playback. The playback options are also limited and in preview still. You can read about this in the [Wowza 4.1.0 release notes](https://www.wowza.com/docs/wowza-streaming-engine-4-1-0-release-notes) Regards, Salvadore ---

According to the Wowza 4.1.0 release notes. The following support for H.265 was added: > Added support for HEVC/H.265 stream ingestion and playback over MPEG-TS (preview) > > Added support for HEVC/H.265 stream ingestion and playback over RTP (preview) There is nothing notable about this in the Wowza 4.2.0 release notes to suggest anything has changed at this point. I can only figure that since HDS is not mentioned that it is not supported at this time. For further questions, you might consider opening a support ticket by emailing support@wowza.com They may be able to provide more detailed information for you in this regard. Salvadore ---

Hi Salvadore, thank you for the help, i was doing this in the past without using _definst_ , but anyway its still not working with that as well, still not going to subdirectory from reason, [http://10.56.194.240:1935/vod/_definst_/mp4:dt/sample.mp4/manifest.f4m](http://10.56.194.240:1935/vod/_definst_/mp4:dt/sample.mp4/manifest.f4m) so now i recognize 2 issues 1. when requesting the file from subdirectory under content its not working, 2. the H.265 file is not playing even when its coming directly from content folder (bbb sample file is working well) thank you for the support Yariv ---
