Investigating Steam for Linux
1er mars 2013, par Multimedia Mike — Game HackingValve recently released the final, public version of their Steam client for Linux, and the Linux world rejoiced. At least, it probably did. The announcement was 2 weeks ago on Valentine’s Day and I had other things on my mind, so I missed any fanfare. When framed in this manner, the announcement timing becomes suspect– it’s as though Linux enthusiasts would have plenty of time that day or something.
Taming the Frontier
Speculation about a Linux Steam client had been kicking around for nearly as long as Steam has existed. However, sometime last year, the rumors became more substantive.I naturally wondered how to port something like Steam to Linux. I have some experience with trying to make a necessarily binary-only program that runs on Linux. I’m fairly well-versed in the assorted technical challenges that one might face when attempting such a feat. Because of this, whenever I hear rumors that a company might be entertaining the notion of porting a major piece of proprietary software to Linux, my instinctive reflex is, “What ?! Why, you fools ?! Save yourselves !”
At least, that’s how it used to be. The proposal of developing a proprietary binary for Linux has been rendered considerably less insane by a few developments, for example :
- The rise of Ubuntu Linux as a quasi de facto standard for desktop Linux computing
- The increasing homogeneity in personal desktop computing technology
What I would like to know is how the Steam client runs on Linux. Does it rely on any libraries being present on the system ? Or does it bring its own ? The latter is a trick that proprietary programs can use– transport all of the shared libraries that the main program binary depends upon, install them someplace out of the way on the filesystem, probably in /opt, and then make the main program a shell script which sets a preload path to rely on the known quantity libraries instead of the copies already on the system.
Downloading and Installing the Client
For this exercise, I installed x86_64 desktop Ubuntu 12.04 Linux on a l33t gaming rig that was totally top of the line about 5 years ago, and that someone didn’t want anymore and handed down to me recently. So it should be ideal for this project.At first, I was blown away– the Linux client is in a .deb package that is less than 2 MB large. I unpacked the steam.deb file and found a bunch of support libraries — mostly X11 and standard C/C++ runtimes. Just as I suspected. Still, I can’t believe how small the thing is. However, my amazement quickly abated when I actually ran Steam and saw this :
So it turns out steam.db is just the installer program which immediately proceeds to download an additional 160+ MB of data. So there’s actually a lot more information to possibly sift through.
Another component of the installation is to basically run a big ‘apt-get install’ command to make sure a bunch of required packages are installed :
After all these installation steps, the client was ready to run. However, whenever I tried to do so, I got this dialog which would cause Steam to close when the dialog was dismissed.
Not a huge deal ; later NVIDIA drivers are fairly straightforward to install on Ubuntu Linux. After a few minutes of downloading, installing and restarting X, Steam ran with minimal complaint (it still had some issue regarding the video drivers but didn’t seem to consider it a deal-breaker).
Using Steam on Linux
So here’s Steam running on Linux :
If you have experience with using Steam on Windows or Mac, you might observe that it looks exactly the same. I don’t have a very expansive library of games (I only started using Steam because purchasing a few computer components a few years ago entitled me to some free Steam downloads of some of the games on the list in the screenshot). I didn’t really expect any of the games to have Linux versions yet, but it turns out that the indie darling FTL : Faster Than Light has been ported to Linux. FTL was a much-heralded Kickstarter success story and sounded like something I wanted to support. I purchased this from Steam shortly after its release last year and was able to download the Linux version at no additional cost with a single click.
It runs natively on Linux (note the Ubuntu desktop window decorations) :
You might notice from the main Steam client that, despite purchasing FTL about a 1/2 year ago and starting it up at least a 1/2 dozen times, I haven’t really invested a whole lot of time into it. I only managed to get about 2 minutes further this time :
What can I say ? This game just bores me to tears. It’s frustrating because I know that this is one of the cool games that all real gamers are supposed to like, but I practically catch myself nodding off every time I try to run through the tutorial. It’s strange to think that I’ve invested far more time into games that offer considerably less stimulation. That’s probably because I had far more free time compared to gaming options during those times.
But that’s neither here nor there. We’ll file this under “games that aren’t for me.” I’m glad that people like FTL and a little indie underdog has met with such success. And I’m pleased that Steam on Linux works. It’s native and the games are also native, which is all quite laudable (there was speculation that everything would just be running on top of a Wine layer).
Deeper Analysis
So I set out wondering how Steam was able to create a proprietary program that would satisfy a large enough cross-section of Linux users (i.e., on different platforms and distros). Answer : well, they didn’t, per the stated requirements. The installation is only tuned to work on Ubuntu 12.04. However, it works on both 32- and 64-bit platforms, the only 2 desktop CPU platforms that matter these days (unless ARM somehow makes inroads on the desktop). The Steam client is quite clearly an x86_32 binary– look at the terminal screenshot above and observe that it’s downloading all :i386 support libraries.The file /usr/bin/steam isn’t a binary but a launcher shell script (something you’ll also see if you investigate /usr/bin/firefox on a Linux system). Here’s an interesting tidbit :
function detect_platform() # Maybe be smarter someday # Right now this is the only platform we have a bootstrap for, so hard-code it. echo ubuntu12_32
I wager that it’s possible to get Steam running on other distributions, it probably just takes a little more effort (assuming that Steam doesn’t put too much effort into thwarting such attempts).
As for the FTL game, it comes with binaries and libraries for both x86_32 and x86_64. So, good work to the dev team for creating and testing both versions. FTL also distributes versions of the libraries it expects to work with.
I suspect that the Steam client overall is largely a WWW rendering engine underneath the covers. That would help explain how Valve is able to achieve such a consistent look and feel, not only across OS platforms, but also through a web browser. When I browse the Steam store through Google Chrome, it looks and feels exactly like the native desktop client. When I first thought of how someone could port Steam to Linux, I immediately wondered about how they would do the UI.
A little Googling for “steam uses webkit” (just a hunch) confirms my hypothesis.

Downscaling a video from 1080p to 480p using swscale and encoding to x265 gives a glitched output
5 mai 2023, par lokit khemkaI am basically first scaling a frame and then sending the frame to the encoder as below :


scaled_frame->pts = input_frame->pts;
scaled_frame->pkt_dts = input_frame->pkt_dts;
scaled_frame->pict_type = input_frame->pict_type;
sws_scale_frame(encoder->sws_ctx, scaled_frame, input_frame);
if (encode_video(decoder, encoder, scaled_frame))
 return -1;


The scaling context is configured as :


scaled_frame->width = 854;
scaled_frame->height=480; 
encoder->sws_ctx = sws_getContext(1920, 1080,
 decoder->video_avcc->pix_fmt, 
 scaled_frame->width, scaled_frame->height, decoder->video_avcc->pix_fmt, SWS_BICUBIC, NULL, NULL, NULL );
 if (!encoder->sws_ctx){logging("Cannot Create Scaling Context."); return -1;}


The encoder is configured as :


encoder_sc->video_avcc->height = decoder_ctx->height; //1080
 encoder_sc->video_avcc->width = decoder_ctx->width; //1920
 encoder_sc->video_avcc->bit_rate = 2 * 1000 * 1000;
 encoder_sc->video_avcc->rc_buffer_size = 4 * 1000 * 1000;
 encoder_sc->video_avcc->rc_max_rate = 2 * 1000 * 1000;
 encoder_sc->video_avcc->rc_min_rate = 2.5 * 1000 * 1000;

 encoder_sc->video_avcc->time_base = av_inv_q(input_framerate);
 encoder_sc->video_avs->time_base = encoder_sc->video_avcc->time_base;


When I get the output, the output video is 1080p and I have glitches like :


I changed the encoder avcc resolution to 480p (854 x 480). However, that is causing the video to get sliced to the top quarter of the original frame.
I am new to FFMPEG and video processing in general.


EDIT : I am adding the minimal reproducible code sample. However, it is really long because I need to include code for decoding, scaling and then encoding because the possible error is either in scaling or encoding :

FFmpeg fails to draw text
6 avril 2024, par Edoardo BalducciI've rarely used ffmpeg before, so, sorry If the question is too dumb.
I have a problem adding a text layer to a video frame using ffmpeg.


This is my current code :


import subprocess
from PyQt5.QtGui import QPixmap, QImage
from PyQt5.QtWidgets import QLabel

class VideoThumbnailLabel(QLabel):
 def __init__(self, file_path, *args, **kwargs):
 super().__init__(*args, **kwargs)
 self.video = video
 video_duration = self.get_video_duration(file_path)
 thumbnail_path = self.get_thumbnail(file_path, video_duration)
 if thumbnail_path:
 self.setPixmap(QPixmap(thumbnail_path).scaled(160, 90, Qt.KeepAspectRatio))
 self.setToolTip(f"{video.title}\n{video.description}")

 def get_video_duration(self, video_path):
 """Returns the duration of the video in seconds."""
 command = [
 'ffprobe', '-v', 'error', '-show_entries',
 'format=duration', '-of',
 'default=noprint_wrappers=1:nokey=1', video_path
 ]
 try:
 result = subprocess.run(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True)
 if result.returncode != 0:
 print(f"ffprobe error: {result.stderr}")
 return 0
 duration = float(result.stdout)
 return int(duration) # Returning duration as an integer for simplicity
 except Exception as e:
 print(f"Error getting video duration: {e}")
 return 0

 def get_thumbnail(self, video_path, duration):
 """Generates a thumbnail with the video duration overlaid."""
 output_path = "thumbnail.jpg" # Temporary thumbnail file
 duration_str = f"{duration // 3600:02d}:{(duration % 3600) // 60:02d}:{duration % 60:02d}"
 command = [
 'ffmpeg', '-i', video_path,
 '-ss', '00:00:01', # Time to take the screenshot
 '-frames:v', '1', # Number of frames to capture
 '-vf', f"drawtext=text='Duration: {duration_str}':x=10:y=10:fontsize=24:fontcolor=white",
 '-q:v', '2', # Output quality
 '-y', # Overwrite output files without asking

 ]
 try:
 result = subprocess.run(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
 if result.returncode != 0:
 print(f"ffmpeg error: {result.stderr}")
 return None
 return output_path
 except Exception as e:
 print(f"Error generating thumbnail with duration: {e}")
 return None


and it is used like this :


for i, video in enumerate(self.videos):
 video_widget = VideoThumbnailLabel(video.file)
 video_widget.mousePressEvent = lambda event, v=video: self.onThumbnailClick(
 v
 )
 self.layout.addWidget(video_widget, i // 3, i % 3)


I'm facing a problem where I am not able to get the thumbnail if I try to add the duration (I've tested it without the draw filter and worked fine)


I get this error (from the
