  • ffmpeg proress 4444 produce low quality output

    3 mai 2017, par Panupat

    I have a bunch of HQ clips in Proress 4444 format with alpha I’m trying to scale down with ffmpeg. The output do produce the correct alpha, however the quality seems really bad. I’m curious if there’s something wrong with my command ?

    ffmpeg.exe -i in.mov -vf scale=iw/2:-2 -c:v prores_ks -profile:v 4444 -pix_fmt yuva444p10le -alpha_bits 16 out2.mov

    Above, output. Below, source.

    the log is here - https://docs.google.com/document/d/19TdJwwDp0QD00f_7XB8sBAYMUWUrn2moRuCC6r6rI0k/edit?usp=sharing

    Any help appreciate, thanks !

  • Installing FFMPEG via WHM Terminal (VPS Server)

    22 juillet 2020, par Alien Joe

    I apologize in advance if any necessary information is missing. Please don't hesitate to comment if I've made any noob mistakes.

    


    What I'm trying to do is install FFMPEG on our VPS following the instructions here : https://stackposts.com/docs/detail/21747459/installating-ffmpeg

    


    I am getting hung up after step 3 - all commands being executed from the Terminal linked inside of our WHM as the root user. I'm getting a permission denied error at step 4, and then errors on every step thereafter if I try to skip it.

    


    I did notice in the course of trying to ad-hoc the install based on other tutorials that the ffmpeg-3.3.4 directory for some reason belongs to another user NOT root. I'm not sure what part of steps 1-3 would have caused this to happen. There may be something there.

    


    I'm hoping someone has run into similar issues and can provide some direction. I've been at it all morning searching for ways to complete this install. I've checked the source file's site, I've reached out to my host, I've reached out to the software support, and I'm reaching out here.

    


    I've accomplished the FFMPEG file downloads - how to I proceed with install ?

    


  • Java IO Streaming Large Files Video/Data/Sound [on hold]

    2 mars 2015, par James Relic

    I have a series of questions listed below regarding java.io streaming and sockets.

    1. What is a video streaming server ? How does it differ from a standard web server.

    2. Remember Napster/Morpheus etc ? They’re P2P programs, did they allow users to stream data to each other ? Is there a difference between streaming and downloading (on the clients end) ?

    3. How would you go about writing a generic program in java that streams anything to the client , word docs, mp3 files, videos files ? Would you use serverlets for this purpose ?

    4. If all you are doing is sending files video/sound/docs/text etc from one computer to another would you need to use specialist APIs like FFMPEG-Java, Red5 ?

    5. if you are sending video or sound as a file supposedly you don’t need to worry about encoding or decoding ?

    6. Do I need to worry about RTSP if im streaming videos as a file ? Rather then wanting them to play live on the client end ?

    I understand my questions sound very untechnical and basic, but I’m a little confused on this whole streaming topic and want to know the best way to stream large files of all types using the Java EE/Spring platform.
