FFMPEG cannot encode .MP4 to usable .Y4M RAW video : "Operation not permitted"
26 janvier 2020, par Ham789I am running ffmpeg version 4.2.2 on macOS Sierra and I cannot decode a RAW video.
First I create the .Y4M video :
ffmpeg -y -i inputfolder/GH012088.MP4 temp_raw_video.Y4MThen I try to input it to ffmpeg :
ffmpeg -i temp_raw_video.Y4MHowever I get the following error in the terminal :
temp_raw_video.Y4M: Operation not permittedI have checked the permissions for the ’temp_raw_video.Y4M’ file and I have both read and write permissions.
I have tried the above with .MOV videos from an iPhone and it works fine.
The problem seems to be with the .MP4 videos I am trying to convert. These videos were taken with a GoPro camera.
What is going on here ? Please see the GH012088.MP4 file info below :

"Smooth" the ffmpeg showwaves video filter output
24 décembre 2019, par goodytxI think I’m close to what I’m after, thanks to excellent answers like : FFMPEG : Fill/Change (part of) audio waveform color as per actual progress with respect to time progress ...but not quite there !
I’m scripting the generation of a waveform video with
showwaves, and overlaying that onto a static image background, turning the whole thing into video. All is well, except I’d like to "smooth" the waveform. In most tutorials/answers you will see jagged "peaks" in the waveform animation, as of course the audio data varies widely into peaks and troughs. (The differences expressed between the lowest and highest amplitude (I think) in each audio frame sample.) I’d like to get more of a consistent "flowing wave", without the sharp spikes up and down.Currently using the filter much as described in the previous link :
[1:a]aformat=channel_layouts=mono,asplit[red][white]; \
[red]showwaves=s=1280x100:rate=15:mode=cline:scale=sqrt:colors=0xff0000[red]; \Which results in the following (ignoring the red on white overlay, which I may drop) :
This generates the type of wave plot I want (solid vs a sine, for example), but I think I need to either tweak the audio stream or...possibly post filter the
showwavesvideo stream (but I think the former) to get the effect I want. I tried to reduce therateofshowwavesbut that just results in juddery video. So to me that feels like the audio data needs to be the changed factor.My limited audio knowledge leads me to think I should gain, compress, normalize, or all of the above, the audio input, which I have tried, but can’t seem to nail it. Keep in mind the audio stream in this filter chain is purely feeding the
showwavesfilter, so I can "trash" it as much as needed in order to get the visualization I want.I hope this all makes sense, and if I need to provide more info, please let me know. Thanks !

FFMPEG "Could not allocate memory" Errors through php
10 décembre 2019, par ApplepieeI’ve tried to find a solution online for days now but cannot find any solution.
I just switched server (Intel Xeon to AMD) and since the switch I’ve not been able to get ffmpeg conversions working through the php script. ffmpeg was the exact same version and all php settings are set.
All commands that the script executes (copied from log files) were tried in shell and executed with no problems.
The errors look like this :
