  • FFmpeg INTEL QuickSync VAAPI FAILURE [unknown libva error]

    11 juin 2019, par Ahmet Gürer

    I have problems with FFmpeg and Intel QuickSync. If I start my ffmpeg command from shell it works correctly. But if I want to start the same ffmpeg command from an cronjob I get Failure with quicksync

    My command is :

    /bin/ffmpeg -vsync passthrough -copytb 1 -hwaccel qsv -probesize 5000000 -analyzeduration 16000000 -c:v hevc_qsv -recv_buffer_size 67108864 -i source -filter_complex "[v:0]hwdownload,format=pix_fmts=nv12[format:0]; [format:0]cvdelogo=filename=file:buffer_queue_size=150:detect_interval=25:score_min=0.4:scale_min=0.75:scale_max=1.25:padding_left=10:padding_right=10:padding_top=10:padding_bottom=10[cvdelogo]; [cvdelogo]split=outputs=1[hwupload:0]; [hwupload:0]hwupload=extra_hw_frames=10[map:v:0]" -map [map:v:0] -c:v h264_qsv -flags:v +global_header+cgop -preset:v veryfast -g 250 -b:v:0 6200k -maxrate:v:0 6200k -bufsize:v:0 6200k -map a:0 -c:a copy -f hls -hls_flags delete_segments -hls_time 10 -hls_list_size 6 output.m3u8

    If I run that on terminal everything works. But if I want to start it from php with shell_exec command over an cronjob I get this failure :

    [AVHWDeviceContext @ 0x2cc7b80] Failed to initialise VAAPI connection: -1 (unknown libva error). Error creating a QSV device

    I don’t know why FFmpeg is not founding the vaapi device from cronjob, pls help me out of this issue.

    Thanks

  • I want to know what is in unknown [WARNING : Unknown codec unknown]

    15 juin 2019, par aomi taka

    I want to new music_bot in my discord.ch
    so I found google cloud platform and Just-some-bot in git hub (https://github.com/Just-Some-Bots/MusicBot)
    I did just fallow to step ubuntu 16.04 in this site (https://just-some-bots.github.io/MusicBot/installing/ubuntu/)

    and I got a problem

    There was no problem running the bot, but An error occurred when I entered a command to download YouTube. [!play url]
    WARNING : Unknown codec unknown

    So I searched for 3 hours for WARNING : Unknown codec unknown
    I couldn’t find anything like that.

    I’ve tried to youtube-dl -U, FFMPEG update, change the locations, make another one, I’ve changed all the progress codes so that I can see them. [in musicbot’s options], change the ubuntu 18.04 [and got the same problem]

  • avformat/matroskadec : Accept more unknown-length elements II

    17 mai 2019, par Andreas Rheinhardt
    avformat/matroskadec : Accept more unknown-length elements II

    Up until now, one last kind of unknown-length element hasn't been
    
properly handled : Unknown-length elements that are supposed to be
    
skipped, i.e. the level 1 elements that might reside after the
    
clusters.
    

    This commit changes this. To do this, ebml_parse got a mode that
    
essentially tries to skip everything except when parsing is needed
    
(namely for unknown-length elements for which parsing is necessary
    
as they can't be skipped). This mode is selected by using a NULL
    
as destination where the parsed data should be written to.
    
It is used to parse the level 1 elements in matroska_parse_cluster.
    

    The syntax list used for parsing must of course include links to
    
the syntax of all the master elements that might need to be parsed.
    
In other words : Instead of matroska_clusters (which contained every
    
level 1 element except clusters as EBML_NONE elements designated to
    
be skipped) matroska_segment is needed and used ; matroska_clusters has
    
been removed.
    

    Furthermore, matroska_segment has been reordered so that clusters are at
    
the front as this is now the most common case for this list.
