[Solved] MKV/MP4 decoding with ffmpeg64 not working [5.1.0]

System: Win 8.1, 64-bit, latest UMS with Java 7 .
Since the update, UMS uses ffmpeg64.exe to do decoding, since it detects it's running on a 64-bit system, I presume. When it tries to launch ffmpeg64, that process fails silently, no info in logs.
The current workaround is to force it to use the 32-bit version (by deleting the original ffmpeg64.exe and renaming ffmpeg.exe to ffmpeg64.exe) - no problems when using that one.
I've attached a log file of me launching a server and trying to play an MP4 file.

Hi forceflow,
i had a similar issue, but in my case it ended up being UMS hat didn't decode correctly to my Samsung TV.
Are you decoding to a Samsung TV by any chances?

Please run the following command in command prompt and see what it says:
Code: Select all
"C:\Program Files (x86)\Universal Media Server\win32\ffmpeg64.exe" -y -i D:\Films\test.mp4 -filter_complex subtitles=D\\:/Films/test.srt:1280x536 -bufsize 7000000 -maxrate 499000000 -g 5 -q:v 1 -qmin 2 -qmax 3 -ab 448k -c:a ac3 -c:v mpeg2video -f vob output.mpeg

Nope, to a Sony Bravia TV.

Anyway running the command I posted before should fix the issue for you, and the issue has also been fixed in the upcoming version.

Running that command with the original ffmpeg64 executable indeed seems to work fine. (the signal 2 is me hitting ctrl-c :p)
