IJG swings again, and misses
1er février 2010, par Mans — MultimediaEarlier this month the IJG unleashed version 8 of its ubiquitous libjpeg library on the world. Eager to try out the “major breakthrough in image coding technology” promised in the README file accompanying v7, I downloaded the release. A glance at the README file suggests something major indeed is afoot :
Version 8.0 is the first release of a new generation JPEG standard to overcome the limitations of the original JPEG specification.
The text also hints at the existence of a document detailing these marvellous new features, and a Google search later a copy has found its way onto my monitor. As I read, however, my state of mind shifts from an initial excited curiosity, through bewilderment and disbelief, finally arriving at pure merriment.
Already on the first page it becomes clear no new JPEG standard in fact exists. All we have is an unsolicited proposal sent to the ITU-T by members of the IJG. Realising that even the most brilliant of inventions must start off as mere proposals, I carry on reading. The summary informs me that I am about to witness the introduction of three extensions to the T.81 JPEG format :
- An alternative coefficient scan sequence for DCT coefficient serialization
- A SmartScale extension in the Start-Of-Scan (SOS) marker segment
- A Frame Offset definition in or in addition to the Start-Of-Frame (SOF) marker segment
Together these three extensions will, it is promised, “bring DCT based JPEG back to the forefront of state-of-the-art image coding technologies.”
Alternative scan
The first of the proposed extensions introduces an alternative DCT coefficient scan sequence to be used in place of the zigzag scan employed in most block transform based codecs.
Alternative scan sequence
The advantage of this scan would be that combined with the existing progressive mode, it simplifies decoding of an initial low-resolution image which is enhanced through subsequent passes. The author of the document calls this scheme “image-pyramid/hierarchical multi-resolution coding.” It is not immediately obvious to me how this constitutes even a small advance in image coding technology.
At this point I am beginning to suspect that our friend from the IJG has been trapped in a half-world between interlaced GIF images transmitted down noisy phone lines and today’s inferno of SVC, MVC, and other buzzwords.
(Not so) SmartScale
Disguised behind this camel-cased moniker we encounter a method which, we are told, will provide better image quality at high compression ratios. The author has combined two well-known (to us) properties in a (to him) clever way.
The first property concerns the perceived impact of different types of distortion in an image. When encoding with JPEG, as the quantiser is increased, the decoded image becomes ever more blocky. At a certain point, a better subjective visual quality can be achieved by down-sampling the image before encoding it, thus allowing a lower quantiser to be used. If the decoded image is scaled back up to the original size, the unpleasant, blocky appearance is replaced with a smooth blur.
The second property belongs to the DCT where, as we all know, the top-left (DC) coefficient is the average of the entire block, its neighbours represent the lowest frequency components etc. A top-left-aligned subset of the coefficient block thus represents a low-resolution version of the full block in the spatial domain.
In his flash of genius, our hero came up with the idea of using the DCT for down-scaling the image. Unfortunately, he appears to possess precious little knowledge of sampling theory and human visual perception. Any block-based resampling will inevitably produce sharp artefacts along the block edges. The human visual system is particularly sensitive to sharp edges, so this is one of the most unwanted types of distortion in an encoded image.
Despite the obvious flaws in this approach, I decided to give it a try. After all, the software is already written, allowing downscaling by factors of 8/8..16.
Using a 1280×720 test image, I encoded it with each of the nine scaling options, from unity to half size, each time adjusting the quality parameter for a final encoded file size of no more than 200000 bytes. The following table presents the encoded file size, the libjpeg quality parameter used, and the SSIM metric for each of the images.
Scale Size Quality SSIM 8/8 198462 59 0.940 8/9 196337 70 0.936 8/10 196133 79 0.934 8/11 197179 84 0.927 8/12 193872 89 0.915 8/13 197153 92 0.914 8/14 188334 94 0.899 8/15 198911 96 0.886 8/16 197190 97 0.869 Although the smaller images allowed a higher quality setting to be used, the SSIM value drops significantly. Numbers may of course be misleading, but the images below speak for themselves. These are cut-outs from the full image, the original on the left, unscaled JPEG-compressed in the middle, and JPEG with 8/16 scaling to the right.
Looking at these images, I do not need to hesitate before picking the JPEG variant I prefer.
Frame offset
The third and final extension proposed is quite simple and also quite pointless : a top-left cropping to be applied to the decoded image. The alleged utility of this feature would be to enable lossless cropping of a JPEG image. In a typical image workflow, however, JPEG is only used for the final published version, so the need for this feature appears quite far-fetched.
The grand finale
Throughout the text, the author makes references to “the fundamental DCT property for image representation.” In his own words :
This property was found by the author during implementation of the new DCT scaling features and is after his belief one of the most important discoveries in digital image coding after releasing the JPEG standard in 1992.
The secret is to be revealed in an annex to the main text. This annex quotes in full a post by the author to the comp.dsp Usenet group in a thread with the subject why DCT. Reading the entire thread proves quite amusing. A few excerpts follow.
The actual reason is much simpler, and therefore apparently very difficult to recognize by complicated-thinking people.
Here is the explanation :
What are people doing when they have a bunch of images and want a quick preview ? They use thumbnails ! What are thumbnails ? Thumbnails are small downscaled versions of the original image ! If you want more details of the image, you can zoom in stepwise by enlarging (upscaling) the image.
So with proper understanding of the fundamental DCT property, the MPEG folks could make their videos more scalable, but, as in the case of JPEG, they are unable to recognize this simple but basic property, unfortunately, and pursue rather inferior approaches in actual developments.
These are just phrases, and they don’t explain anything. But this is typical for the current state in this field : The relevant people ignore and deny the true reasons, and thus they turn in a circle and no progress is being made.
However, there are dark forces in action today which ignore and deny any fruitful advances in this field. That is the reason that we didn’t see any progress in JPEG for more than a decade, and as long as those forces dominate, we will see more confusion and less enlightenment. The truth is always simple, and the DCT *is* simple, but this fact is suppressed by established people who don’t want to lose their dubious position.
I believe a trip to the Total Perspective Vortex may be in order. Perhaps his tin-foil hat will save him.

h264 extracting frames works only on certain operating system / ffmpeg version
15 juin 2018, par J. S.I have received parsed h264 data from my phone, and I am trying to extract frames from the data.
I used the following ffmpeg command lines :
ffmpeg -i temp.h264 -ss 5 -pix_fmt yuv420p -vframes 1 foo.yuv
ffmpeg -s 1280:720 -pix_fmt yuv420p -i foo.yuv output.jpgThis results in the right output image on Ubuntu (KDE neon User Edition 5.12) with ffmpeg version 2.8.14.
However, it does not work on macOS High Sierra (10.13.4) with ffmpeg version 4.0 and instead shows an output message :
Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used)I am not sure whether this is a mere ffmpeg version-related issue or not because as an experiment, when I converted the h264 data into mp4 format and played it on macOS High Sierra, the video sometimes shows a sequence of black distorted image (screenshot), and other times, a normal video.
If I play that same video on Ubuntu (KDE neon User Edition 5.12), the video plays perfectly.
I don’t understand why this problem would occur, and whether this has to do with OS or ffmpeg library version.
What would be some good ways to approach this problem ? Thanks.EDIT :

Android FFmpegPlayer Streaming Service onClick notification
8 octobre 2013, par agonyI have a MainActivity class that displays the list of streams available for my project and the StreamingActivity class where the streaming is done.
If the user selected an item from the list it will start the StreamingActivity and start playing the stream.
I'm having trouble to continue streaming music when the user pressed the notification and returning it to the StreamingActivity class if the user pressed or clicked the home menu or when the app goes to onDestroy().I'm using FFmpegPlayer for my project 'coz it requires to play mms :// live streams for local FM station.
Here's my code :
