Hello.

Please check the playback URL for typos. It looks like you have .mp4.mp4 as the extension:

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:

[[I]protocol[/I]]://[[I]ip-address[/I]]:1935/vod/_definst_/mp4:[[I]sub-folder-name[/I]]/mp4:[[I]some-file[/I]].mp4

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

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.

you right,

that was after to many tries and was mistake

the problem now is when i try to play i “get Playback failed null” with no specific reason - i have checked the content with VLC and he played well

from the logs i can see that the system is not looking at folder dt

from the logs : MediaReaderH264.open[vod/dt]: Not found: /usr/local/WowzaStreamingEngine/content/BBB_Main_10s_deu_20_16000k-HEVC-4K.mp4.: java.io.FileNotFoundException: /usr/local/WowzaStreamingEngine/content/BBB_Main_10s_deu_20_16000k-HEVC-4K.mp4 (No such file or directory)|at java.io.RandomAccessFile.open(Native Method)|at java.io.RandomAccessFile.(RandomAccessFile.java:243)|at com.wowza.io.WowzaRandomAccessFile.(WowzaRandomAccessFile.java:12)|at com.wowza.io.DirectRandomAccessReader.open(DirectRandomAccessReader.java:236)|at com.wowza.wms.mediareader.h264.MediaReaderH264.open(MediaReaderH264.java:252)|

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

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

so , this is the right syntax that its working with subfolder http://10.56.194.240:1935/vod/mp4:vod/dt/mp4:sample.mp4/manifest.f4m but still H265 content is not playing
