The VideoLAN Forums

Been using it on all my computers for at least 6 months, can't tell any difference between it and the 32bit version. I can tell the difference when I transcode to x265 a live stream input in realtime and restream it. There's like 30% increase in needed processing power for the 32bit variant... ie I...

Hi, Where do you think I can get more info about x265 and its practical uses with VLC? Because it seems these forums aren't exactly lively, so maybe it's the wrong place for noob users like me who try to get thinks working. I get acceptable results, but I'm not there yet, particularly for the upstre...

No, i didn't find a solution. As I understand, x265 is pretty much a work in progress and most options are not activated yet. I guess there's a documentation related to the x265 version included in the last VLC nightlies. as for x264, I played a bit with it in the past, before being able to use x265...

So I started using latest winx64 nightly to transcode a live streaming input with HEVC and restream the output all in realtime on a xDSL line with a 1mbps upload limit. The input live stream is either a 576p50 x264 2 mbps stream or a 1080p50 5mbps x264 stream. I do not encode the audio, I only reenc...

6 months later, big update: The computer I used for the transcoding has been replaced by an overkill machine with an i7-4790k enough ram and a SSD. Thing is, the power reserve is so immense I can transcode 1080p to 720p25FPS HEVC with a 1mbps target in realtime and still only use 80% of the processi...

So far, the encoding works, with problems related to the encapsulation. Avi: Works, image is fine, but no audio is muxed MP4: it seems it works, but the file is not playable with either VLC or other HEVC compatible players. MKV: Works, but video is sometimes garbled, like every 3 seconds. Audio is p...

I wonder if I can speak my trial and errors here...

So, with a transcode command to only encode in hevc and resize the video so that the encoding time is not too long, I get files that can't be played with VLC itself. I'll post a log later. I wonder if I should start a new thread.

Ok thanks for the help.
So the error is "generic" unless you watch the logs. Clear them and then see what happens.
After setting height/width manually, the encoder started.

Now I will try different settings and see what happens.
Thanks a lot!

Thanks for the reply. Regarding the flv settings, well at the time I wanted to try realtime transcoding, and adjusting size/parameters if needed. I used the gui that got me those settings. But even a file convert gives the same error. Example: vlc.exe "input.h264" :sout=#transcode{vcodec=h...

So "vlc --list" shows x265 as an encoder.
But "vlc -p x265 --advanced" says there's no module by that name.

Can someone just drop a word to confirm there's no usable x265 encoder in vlc yet?

I've been trying to update to latest FFmpeg since the error message states it doesn't come from VLC.
But it seems I'm not skilled enough to understand what happens... and what to do to correct my problem.

Any help appreciated.

Thanks

Yup, it was up sometime after I posted.
It probably just was a coincidence, the server being up again after I posted

Hi,
It seems that the server(s) for the nightlies is(are) down. Seems like it started on May 1st.
I guess people from the team are already aware?

Have a nice day,
David

First I'd try to increase verbose mode and check messages. Maybe you've got hints there. Next, I'd try to do the same thing, but with a source file instead of a stream, to reduce the possible sources of problems. If it works with a file, then the problem would be with the stream. I'd try to play tha...

Hi, I wanted to try to use HEVC for a transcoding task. I downloaded a nighlty build (vlc-2.2.0-git-20140430-0402) To start from something simple, I used the built-in vlc functions and got those parameters: :sout=#transcode{vcodec=hevc,scale=0.25}:http{mux=ffmpeg{mux=flv},dst=:8080/} :sout-keep Then...
