#4344: XSUBs are too low in PAL video, on PS3 -------------------------------------+------------------------------------- Reporter: edumj | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: xsub dxsb | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Hi, I'm making test with subtitles, and when I try to convert a PAL VOB to Xvid with embed subs (idx/sub to xsub) it looks ok in VLC, but stretched and off the screen in PS3. It seems that only happens with videos with height over 480 pixels, because 720x480 subs are ok in PS3. It's like the PS3 thinks the bitmap subtitle are 720x480 and stretches them to 720x576, so lower subs are off the screen. Does the "-scodec xsub" encoder has any options?? I didn't find any info about xsub encoder, nor any parameters in FFMPEG documentation. Are the bitmaps fullscreen or clipped? Is there a way to set position of subs? It's like the bitmaps are 720x576 but marked somewhere as 720x480?? Summary of the bug: How to reproduce: {{{ ffmpeg -i input -scodec xsub output ffmpeg versión N-70148-g418be7c built with gcc 4.9.2 (GCC) }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/4344> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#5891(undetermined:new): "-t" not applied to streams when using channelsplit filter

#5891: "-t" not applied to streams when using channelsplit filter -------------------------------------+------------------------------------- Reporter: MReedAustin | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: I was using volumedetect to check each channel of a file to ensure that program start handles were mute, and got misleading readings when the incoming audio was split (using channelsplit). I have fixed my code by using atrim instead of -t but though the inconsistency was worth highlighting. How to reproduce: {{{ (Any stereo audio source) ffmpeg -ss 149 -i [stereo wav] -filter_complex "[0:0] channelsplit=channel_layout=2c [A1] [A2], [A2] anullsink, [A1] volumedetect" -t 0.96 -vn -f null - Results in: [Parsed_volumedetect_2 @ 0000000002a463a0] n_samples: '''135634560''' [Parsed_volumedetect_2 @ 0000000002a463a0] mean_volume: -25.3 dB [Parsed_volumedetect_2 @ 0000000002a463a0] max_volume: -7.7 dB [Parsed_volumedetect_2 @ 0000000002a463a0] histogram_7db: 57 [Parsed_volumedetect_2 @ 0000000002a463a0] histogram_8db: 40871 [Parsed_volumedetect_2 @ 0000000002a463a0] histogram_9db: 98220 whereas: ffmppeg -ss 149 -i [stereo wav] -filter_complex "[0:0] channelsplit=channel_layout=2c [A1] [A2], [A2] anullsink, [A1] atrim=start=0:duration=0.96, volumedetect" -vn -f null - results in: [Parsed_volumedetect_3 @ 00000000003400c0] n_samples: '''46080''' [Parsed_volumedetect_3 @ 00000000003400c0] mean_volume: -91.0 dB [Parsed_volumedetect_3 @ 00000000003400c0] max_volume: -91.0 dB [Parsed_volumedetect_3 @ 00000000003400c0] histogram_91db: 46080 ffmpeg version N-81894-g54220ce Zeranoe build }}} Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker. -- Ticket URL: <https://trac.ffmpeg.org/ticket/5891> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
