Convert .mp3 to .mov or .mp4 on iPhone SDK
2 août 2014, par SebastianHow are you guys ? I’m working on a little idea I had yesterday and I’m a little stuck with an mp3 conversion.
At this time, my app does the following :
- Receive an input text.
- The app generate a speech using an online API and download the generated .mp3 file to the app document’s folder.
Now I need to convert the .mp3 to .mov or .mp4 and then grab it to the camera roll, so the user can share the video on Facebook, Whatsapp, or wherever he wants.
Is there some easy and memory friendly way to convert from .mp3 to .mp4 without "writing a video" ?
Thank you ! -
Mathematically lossless encoding and decoding of RGB24 image sequence
25 avril 2013, par curryageI am trying to encode a RGB24 image sequence into a mathematically (not merely visually) lossless video. huffyuv was suggested on many online forums so I tried the following.
ffmpeg -i frames\%06d.png -vcodec huffyuv test.avi
The resulting video was then decoded into frames again using ffmpeg
ffmpeg -i test.avi outframes\%06d.png
However, the input and output frames are not bit-by-bit identical as promised by huffyuv here. Any idea how I can accomplish this ? My eventual goal is to read the video file using OpenCV but I am willing to cross that bridge later once I obtain a losslessly encoded video file.
This SO question mentions an attempt to obtain a lossless h264 avi and the summary of responses seems to indicate h264 cannot completely accomplish lossless encoding.
Once again, to emphasize, I am interested in bit-by-bit identical encoding, not just visually similar. Large file sizes are acceptable as is large compression/decompression time.

Installing Older FFmpeg Version Using Homebrew
19 mars 2015, par mf_2015I have the latest version of Homebrew and FFmpeg on OSX 10.9.5.
I need to install an older version of FFmpeg using Homebrew, rather than just running :
brew install ffmpeg
Could someone please explain how to do this ? I know older versions of FFmpeg are readily available online : just need to figure out how to get Homebrew to find them, either online or on my system after downloading.
MF.
