Streaming and recording of lecture theatres

The information in this section applies to A217, A218, A318, A319, A320 and, to a limited extent, lecture theatres outside the Faculty of Informatics. Please direct any feedback regarding this section to .

Audio for the stream is captured by ambient microphones – there is no need to bring a microphone. Sound from the computer is captured only indirectly, via ambient microphones. The video feed consists primarily of the computer screen, with a smaller picture-in-picture (PiP) view of the lectern. Unlike the audio, video streaming is subject to the lectern being activated; Unlike the audio, video streaming is conditional upon the lecture theatre being activated; furthermore, the lecturer cannot adjust the status or configuration of the stream on site.

Video streams from faculty lecture theatres are publicly available: A217, A218, A318, A319, A320. We provide information regarding streaming and recording from these rooms on their timetable panels. The error message ‘The media could not be loaded’ with the CESNET logo indicates that the stream is switched off; a black screen with sound indicates that the department has not been activated. Streaming is temporarily disabled across the board during the spring 2026 examination period. By default, streaming is enabled for lectures (the course code does not contain a slash), non-teaching bookings and during times when there is no event in the timetable. By default, it is disabled for tutorials (the code contains a slash). Streaming can be disabled for a given course or non-teaching booking upon request. For seminars, streaming can be enabled – however, please consider the risk of reduced attendance at seminars and also the exposure of students’ work on the blackboard to the internet. See the overview of streaming status.

Events can only be recorded when streaming is enabled! From spring 2026, recordings will be processed by the new video.fi.muni.cz system from unix@fi (which responds dynamically to timetable changes); the existing video.muni.cz system is now merely being phased out. Unedited lecture recordings are automatically uploaded within approximately one hour of the end of the recording to the folder /vi/ in the course materials for the module in IS, without access for students. When creating the folder /vi/ and uploading the first recording, lecturers are informed of the option to make the recordings accessible. The same applies to tutorials with an explicitly requested stream: these recordings are accessible to all students on the course (however, it is possible to manually adjust access rights to individual recording files at a later date). In the event of an urgent need to prevent the publication of a specific recording, immediately revoke access rights to the folder /vi/ for students in the IS and then contact us to resolve the matter. Recordings of non-teaching events will be made available (and, where necessary, edited) on request. Recordings are edited (in preparation for exams) throughout the semester, subject to time constraints.

Statistics on recording downloads are available here. You can filter them by period and course code.

Additional equipment in classrooms

Instructions for using the equipment:

• classrooms with Linux PCs: Technical manual for teachers in Linux classrooms,
• classrooms in A2 and A3: PC classrooms, lecture theatres by capacity ( 20, 40, 80),
• Classrooms in C: lecture theatre C416.

Ceiling-mounted projectors are available in other classrooms. The key to the cupboard containing the projector remote control can be borrowed for the whole semester from the secretary (office B513), or if you have a key to any of the offices, you can use that to open the cupboard as well. If you need to project in other areas, a portable projector can be borrowed on a short-term basis from the reception.

Please direct any suggestions regarding the department’s operations and management, and the use of AV equipment in general, to .

Resolving problems and dealing with unusual situations

See ‘Contacts for enquiries and reporting issues’.

Software in PC classrooms for teaching

Well in advance (at least two weeks) of the start of teaching, you must submit your software requirements for the teaching itself, i.e. specify which software, which version, in which classrooms and from when it is to be available. Information should be sent to , or , or both, depending on the type of operating systems on the computers in the relevant classrooms. Before the start of classes, it is advisable to test that the required software is working properly.

Faculty services (GitLab, etc.) for teaching

In the faculty’s GitLab, it is possible to set up groups that can be automatically synchronised according to the lecturers and/or students of the course.

If you are interested in a course website, please see the website options, where you will most likely be interested in the GitLab Pages or Web Directory Space sections.

Similarly, within the faculty’s Stratus.FI virtualisation environment, we can arrange for the creation of user groups that can be automatically synchronised according to the students enrolled on the course. It is also possible to set up private networks, e.g. for teaching networking courses. Subject to timely agreement we can also arrange for the bulk provision of environments – see the example on our blog.

Ensuring awareness of the rules of use

For courses held in computer labs, students (as well as lecturers) should be made aware of the operating rules and must adhere to them. In particular, this includes a ban on tampering with the cabling in the classrooms (with the exception of cables for connecting their own machines) and a ban on switching off or restarting machines.

In the case of a course that involves running more demanding calculations, students must be informed of the rules governing the running of resource-intensive processes.

In the event of a breach of the rules, a student’s account may be temporarily blocked, regardless of any inconvenience this may cause them.

Network in teaching rooms

In departmental teaching rooms, there is typically an Ethernet cable connected, which, following authentication via https://wifi.fi.muni.cz/ using faculty login details, provides a connection to the internet. (This can be used as a more reliable and faster alternative to the Wi-Fi network wlan_fi.)

Exams in the computer lab

During the examination period, large courses may also use the computer lab ( room B106), which has 73 Linux computers and 20 dual-boot computers ( map of the computer lab). Dual-boot computers are set to Linux by default during the exam period; the 6 macOS machines cannot be used for exams. Slots must be booked via IS:

• If your needs can be met by other computer labs, please give them priority.
• Book at least one week in advance – the PC hall is also used by students for independent study.
• Minimise the number of exam days in the PC hall. Where possible, use free time slots on days when other exams are taking place.
• Book time slots consecutively from the morning so that the exam block takes place first and the computer hall is then available for the rest of the day (from 18:00 at the latest) for students.
• If possible, at least one computer lab should be available to students as an alternative during the exam.

If using containerisation, please refer to the relevant section here and also bear in mind that disk space is more limited on dual-boot systems (we share space with Windows) or non-stop machines ( /var/tmp is more full) – avoid these where possible.

Following consultation with unix@fi or win@fi, test modes may be used (see the following section). Please submit your requests in good time; for exam sessions with a restricted environment, or if you have not yet used exam mode, please submit your request at least one month in advance!

Please send exam dates as a CSV export from the IS (we strongly discourage manual transcription – it is prone to errors): Managing exam dates → Further operations with dates → Export dates. Select the CSV format for Excel and UTF-8 encoding (without BOM). Please also specify the duration of the exam sessions.

Exam sessions with the IS answer key

On both Linux and Windows computers, it is possible to use a special restricted session, in which students, via the home page, can only access pre-defined URLs in the browser (typically the answer sheet in the IS). In this session, the following are not possible: manipulating the address bar, or accessing other programmes and files on the PC.

To use this exam session, please email and/or (depending on the computers required) with the times and rooms for the exams, and for each time slot, the URL of the exam portal in the IS (this is the address of a file with the extension .qref). For Windows computer labs, please specify whether you wish to keep any computers in normal mode as a teacher’s computer.

Enabling and disabling answer sheet mode on Linux computers will require an action to be carried out by the invigilator in the Faculty Administration system at the start of the exam. Details will be provided by the administrators. At the end, do not forget to end the exam session (Linux) or ensure that students have logged out (Windows).

Exam sessions with a restricted environment

In Linux classrooms and the hall, you can use a restricted environment (not only) for programming examinations, in which students can use text editors, programming language interpreters, etc., but do not have access to the internet or their own files.

We will tailor the session parameters (available software from modules and standard sessions, network restrictions, available offline documentation) to suit your course. The method of distributing assignments and collecting solutions also needs to be agreed in advance; currently, we are connected to the Frag system (managed by and Dr Ročkai ) and submissions are made via a web application on Aise. We can set up other methods as required. To allow students to try out the special session in a trial run, we can set aside one computer in the computer lab on which a demonstration version of this session will run continuously.

The start of the session and each time slot is managed manually by the lecturer via the Faculty Administration application, in which they have the right to control the computers in the classrooms at agreed times. Once all exam slots have finished, the lecturer must cancel the restricted session and thus restore the computers to their normal state.

If you are interested in using this exam session, please contact well in advance. We will discuss the technical details with you. If you wish to use standard Windows PCs (Titans in the hall) outside the exam period, please also include in your email.

Using containers in Linux classrooms

If you plan to use Podman containers in lessons on Linux machines, bear in mind that containers can take up a significant amount of space on the local shared drive (containers are stored in /var/tmp/containers) and try to conserve space by:

• assign students fixed seating arrangements (this will also prevent images from being downloaded repeatedly)
• give preference to pre-built images ( Docker Hub or GitLab Container Repository) rather than having students build them themselves
• to reduce the load on the network and storage (parallel initial downloads on first use), please contact us at to agree on the distribution of files in advance if they exceed 5 GB
• we cannot guarantee that data on /var/tmp/containers will remain available for the entire semester
• Once you have finished your work, please ensure you clean up properly! podman system prune -a will delete terminated containers and images (see the link below for further tips)

See also the information on the page about Linux classroom machines.

Seating plans for computer labs

If you wish to view the current list of students logged in to the computer labs, you can use the room map.

To arrange seating for students during exams in computer labs and lecture theatres, you can use the seating plans.

Bulk conversion between the computer lab and faculty logins

To convert between the UČO and faculty logins, you can use the scripts uco2login and login2uco, which are hosted on the Aisa and Anxur servers.

For instructions on how to use them, see uco2login --help.
