Avidemux Forum

It just blows my mind to see MPEG-PS effectively pulled out of the grave to store HEVC. I'll ask you later to re-upload a sample, please don't do it on your own. For now, Avidemux can handle only MPEG-1 and MPEG-2 in MPEG-PS, both for loading and saving.

I attached the analysis.
Thank you.

Thank you very much for the log. Avidemux crashes on failure to load a file misdetected as MPEG-PS because of an unitialized pointer of type psPacketLinear which should be initialized to NULL.

Could you please attach the textual analysis by MediaInfo for that A02_20250210214208.mp4 file to your reply? It is either not really a MP4 file (the MP4 demuxer in Avidemux rejects it) or it is prepended by some proprietary metadata which confuses file type detection in Avidemux.

Please don't try to post textual MediaInfo output inline – CleanTalk doesn't like that.

Is this video HDR?

Please find attached the log file.

Thank you.

I took a 1080p video using OBS and AMD H265. The video colors came out OK...i then tried downscaling it to 720p and Mpeg4 AVC (x264) in Avidemux and the colors came out grayish.

What video output/settings should i be using to avoid the colors becoming grayish? I want to avoid using HEVC (x265) if possible because windows refuses to display thumbnails for videos using x265...

Please start Avidemux (r241212), reproduce the crash and attach the entire log file (%localappdata%\avidemux\admlog.txt) to your reply, ZIP-compress it if it is too large.

The crash report suggests that Avidemux crashes in MPEG-PS demuxer which absolutely cannot be used in connection with HEVC as MPEG-PS is MPEG-1 / MPEG-2-only.

I wasn't able to look at the samples while they were available, sorry for that. Please provide the log first, thank you.

I tried to open the files in Avidemux 2.8.2 (241212_ce994de41a6-fflibs 7.0.2).

This time I got following error:

Please first verify that the problem persists with the latest known good nightly build which is currently r241212 before reporting issues, thank you.

Please disregard the almost entirely obsolete Wiki altogether, it reflects mainly the features of the long gone Avidemux 2.5.
