  • What can be the substitute for SDL to direct ffmpeg decoded videos to screen in IOS ?

    18 octobre 2012, par jAckOdE

    I making a iOS video player using ffmpeg, the flow likes this :

    Video File---> [FFMPEG Decoder] —> decoded frames —> [a media director] —> /iphone screen (full and partial)/

    A media director will handle the tasks of rendering decoded video frames to iOS ui (UIView, UIWindow etc), outputting audio samples to iOS speaker, and threads management.

    SDL is one of those libs, but SDL is mainly made for game making purpose and seem to be not really mature for iOS.

    What can be the substitute for SDL ?

  • azap from LinuxTV dvb-apps strange signal behavior with Hauppauge WinTV-HVR 950Q [migrated]

    27 février 2012, par mmoment

    What I want to do

    I have a Hauppauge WinTV-HVR 950Q USB-TV-Stick. I want to use this stick to successively tune to and read in a certain live TV stream.

    What I do

    I trigger a scan and save the scan results in a file. I call it channels.conf, like the v4l documentary proposes.

    scan /home/username/Documents/dvb/atsc/us-CA-SF-Bay-Area > /home/username/Documents/dvb/atsc/conf/home_channels.conf

    Everything works fine, the scan returns something like this(A correct channel file) :

    [0003]:503000000:8VSB:49:52:3
    
[0005]:503000000:8VSB:81:84:5

    Then I tune to a channel from the scan results. KIDS for example :

    azap -r -c Documents/dvb/atsc/conf/channels.conf KIDS

    What I expect the program to do :

    I expect the program to be tuned and to deliver results similar to this :

    username@username:~$ azap -r -c Documents/dvb/atsc/conf/channels.conf KIDS
    
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
    
tuning to 689000000 Hz
    
video pid 0x0061, audio pid 0x0064
    

    
status 1f | signal 00e6 | snr 00e6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 1f | signal 00e6 | snr 00e6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 1f | signal 00e6 | snr 00e6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 1f | signal 00dc | snr 00e6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 1f | signal 00e6 | snr 00e6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 1f | signal 00e6 | snr 00e6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
...

    What it does :

    In 2 out of 5 tries the azap just doesn't work at all.

    username@username:~$ azap -r -c Documents/dvb/atsc/conf/channels.conf KIDS
    
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
    
tuning to 689000000 Hz
    
video pid 0x0061, audio pid 0x0064
    

    
status 00 | signal 0000 | snr 00e6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 00 | signal 0000 | snr 00e4 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 00 | signal 0000 | snr 00e6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 00 | signal 0000 | snr 00c2 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 00 | signal 0000 | snr 00e6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
...

    The rest of the time it generally works initially, then switches the status to 00 and can not be used any more, even if there is incoming signal.

    status 1f | signal 00dc | snr 00dc | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 1f | signal 00d2 | snr 00dc | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 1f | signal 00dc | snr 00dc | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 1f | signal 00dc | snr 00dc | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 1f | signal 00d2 | snr 00d2 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 1f | signal 00c8 | snr 00d2 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 1f | signal 00d2 | snr 00d2 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 00 | signal 00d2 | snr 00d2 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 00 | signal 00d2 | snr 00d2 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 00 | signal 00d2 | snr 00d2 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 00 | signal 00dc | snr 00dc | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 00 | signal 00e6 | snr 00e6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 00 | signal 00dc | snr 00dc | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 00 | signal 00e6 | snr 00e6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 00 | signal 00e6 | snr 00e6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
status 00 | signal 00e6 | snr 00dc | ber 00000000 | unc 00000000 | FE_HAS_LOCK
    
...

    The output even shows that there is high signal to noise ratio, low or rather no block errors or uncorrected errors at all at first, then it
    This keeps me wondering since I see no reason for the program to switch. After double checking with a real TV I am very sure that I always have an incoming signal and that there should not be any reasons for a behavior like this.

    Question

    Can any of you guys see a reason for this behavior, could it be a problem with the Hardware that I'm using or rather a Software issue ? Did anybody experience the same issues, how did you fix it ? Any help is greatly appreciated !

  • ffmpeg target file size 0

    3 octobre 2012, par user1165201

    I would like to ask a question about "ffmpeg"

    I use the following command to chunk a video around 12 minutes. But after over 80 chunks, the target file size is 0.

    "ffmpeg -i " + wav_path + " -ss " + ff_hhmmss_video(t1) + " -t " + ff_hhmmss_video(t2-t1) + " -acodec copy -async 1 -y " + temp_filename

    I would like to get some suggestions about this. Thanks.
